RESUMEN
The success of implants depends on the biological and mechanical factors of the implant, as well as on the chosen prosthesis, which has different characteristics that can affect the survival of the implant and its marginal bone levels. Therefore, when choosing the type of prosthesis, it is necessary to understand and consider each of these variables and tailor them to the relevant clinical situation. In this narrative review, we will assess the types of prostheses, their different characteristics, timing, and their impact on implant survival and marginal bone levels, as accepted in today's literature.
RESUMEN
Clinicians who place and restore implants are always concerned about the success and longevity of the same. There are several local and systemic factors that affect osseointegration and the health of the peri-implant tissues. In this study, we review the systemic factors that can affect implant survival, osseointegration, and long-term success. The study highlights the importance of delineating, and taking into consideration these systemic factors from the planning phase to the restorative phase of dental implants. A thorough medical history, including prescription and over-the-counter medications, is vital, as there may be numerous factors that could directly or indirectly influence the prognosis of dental implants.

PURPOSE: The present study evaluated osteopenia (OPN) and osteoporosis (OP) as risk factors for dental implant failure and repeat failure. METHODS: We performed a retrospective study on over 100 randomly selected patients per analysis to determine the effect of health status, smoking status, sex, implant location and operative conditions on first and second (re-implantation) implant survival. Analyses were conducted first using chi-squared test, followed by multiple logistic regression for significant variables. RESULTS: In the cohort examining the effect of myriad risk factors on second implant survival, it was found that OPN and OP greatly impacted implant survival, wherein patients with osteoporosis or osteopenia had significantly more implant failures (p = 0.0353). Sex and operative conditions had no effect on implant survival, while implant location showed a notable effect wherein significantly more failures occurred in the maxilla vs mandible (p = 0.0299). Upon finding that OPN and OP have a significant effect on second implant survival, we conducted an additional study focusing on the impact of health status. Based on the multiple logistical regression analysis, we found that OPN and OP are the most significant factor in first implant survival (p = 0.0065), followed by diabetes (p = 0.0297). Importantly, it was observed that early implant failure is also significantly correlated with osteoporosis (p = 0.0044). CONCLUSION: We show here a marked relationship in which the risk of first and second implant failure are significantly higher in patients with osteoporosis and osteopenia.

Successful dental implant therapy relies on a bone-implant interface that is mechanically strong and capable of dynamic remodeling in response to functional loads. There are a number of medical conditions or therapies that can affect either bone metabolism or the resistance of bone to infection. However, their effects are often mitigated by local factors or individual responses so the impact of these conditions is not clear-cut. This article will review a number of these conditions and therapies and describe existing studies that have studied these conditions to guide practitioners in their implant practice.
RESUMEN
BACKGROUND: Total shoulder arthroplasty (TSA) is a common procedure that may be considered for patients with glenohumeral osteoarthritis. Patients undergoing this procedure may be afflicted by comorbid conditions, such as systemic lupus erythematosus (SLE), which may impact odds of various postoperative complications. METHODS: Adult patients with and without SLE who underwent TSA (anatomic or reverse) were queried from the Jan 2010 to Oct 2022 PearlDiver M165 database. Patients with and without SLE were matched (1:4) based on age, sex, and Elixhauser Comorbidity Index. Ninety-day adverse events and five-year implant survival were assessed and compared with multivariable analysis. Sub-analyses were done for SLE patients with and without a prescription of immunomodulatory therapy (IMT - corticosteroids, hydroxychloroquine, and/or biologics) within 90 days prior to surgery and compared to non-SLE patients with multivariable analyses. Lastly, SLE patients with and without a 90-day history of IMT were directly compared with multivariate logistic regression. A Bonferroni correction was applied to univariable analyses and multivariable regressions. RESULTS: Of 211,832 TSA patients identified, SLE was noted for 2,228 (1.1%). After matching, 8,261 patients without SLE and 2,085 patients with SLE were selected. SLE patients were at an increased odds of 90-day aggregated events including severe (OR=3.50), minor (OR=3.13), all (OR=2.35), and orthopedic-related (OR=1.41) adverse events (p<0.0030 for all). There was no difference in 5-year implant survival. Of those with SLE, IMT medications were being received by 1,267 (60.8%). Any, severe, minor, and orthopedic 90-day adverse events were significantly elevated for both those with and without IMT relative to those without SLE (p<0.0030 for all except for orthopedic-related adverse events for those not on IMT which were not significant). Relative to those not on IMT medications, those on IMT medications were at significantly higher odds of any, severe, minor, and orthopedic-related adverse events. CONCLUSION: Following TSA, patients with SLE were found to be at an increased odds of 90-day adverse events but not of 5-year revisions. Furthermore, those on IMT medications were at higher risk of any, severe, minor, and orthopedic-related adverse events compared to those who were not on these medications. These findings may help with patient counselling and surgical planning when those with SLE are considered for TSA.
RESUMEN
This systematic review investigates the probable effect of proton pump inhibitor (PPI) use on the severity of periodontal disease and peri-implantitis and implant survival. We conducted a literature search in PubMed, Scopus, and Cochrane Central Library up to April 2024. Two review authors independently screened the title and abstracts and then the full texts of retrieved studies. Observational and clinical trial studies that assessed the association between PPIs use and periodontal disease severity and peri-implantitis or implant survival were included. Data extraction from the included studies was done by two reviews independently. Of 940 studies initially retrieved from online searching, 7 research met the inclusion criteria. Three studies examined periodontitis, while four focused on peri-implantitis and implant longevity. On the contrary, evidence regarding the impact of PPIs use on peri-implantits and implant survival is conflicting. Therefore, more well-designed RCTs are warranted to come to a definite conclusion. Since proton pump inhibitors alter the gut microbiome, and affect bone, plus the pathogenesis and etiology of periodontal disease are affected by bacteria within the periodontal pocket, it is hypothesized that they may affect periodontal pathogenesis.
RESUMEN
INTRODUCTION: The integrity of the femoral bone is crucial when considering reconstructive options for the first-time revision of a total hip arthroplasty (THA). Aseptic loosening of primary stems, whether cemented or uncemented, significantly affects the volume and quality of resultant femoral bone loss. This study evaluates the impact of the initial fixation method on femoral bone defect patterns by comparing the extent of bone loss. MATERIALS AND METHODS: A retrospective cohort of 215 patients with either cemented or uncemented stems, indicated for aseptic stem loosening, and undergoing first-time stem revision from 2010 to 2022 at our institution was analyzed. Femoral bone loss extent at first-time revision was preoperatively gauged using radiographs and categorized by the Paprosky classification. Survival probabilities pre-first-time revision for both stem types were calculated using Kaplan-Meier methods. Hazard ratios were applied to compare the risk of initial revision for uncemented versus cemented stems within the first and subsequent 2nd to 10th years post-primary implantation. RESULTS: Cemented stems were associated with a higher occurrence of significant bone defects of type 3a (23.53% vs. 14.02%, p = .108), 3b (39.22% vs. 1.22%, p < .001), and 4 (3.92% vs. 0.00%) compared to uncemented stems. Conversely, smaller defects of type 1 and 2 were more prevalent in uncemented stem loosening (84.76% vs. 33.33%, p < .001). Notably, cemented stems exhibited a significantly prolonged revision-free period over the complete decade following primary insertion (p < .001). The unadjusted risk of first-time revision due to stem loosening showed a tendency to an increase in uncemented stems within the initial postoperative year (HR 5.55, 95% CI 0.74; 41.67, p = .096), and an adjusted risk of 2.1 (95% CI 0.26; 16.53, p = .488). However, these differences did not reach statistical significance. In the subsequent 2nd-10th years, the risk was lower compared to cemented stems (HR 2.35, 95% CI 1.39; 3.99, p = .002). CONCLUSIONS: Uncemented primary stems necessitating first-time revision due to aseptic loosening demonstrated notably smaller femoral bone defects in comparison to primary cemented stems.
RESUMEN
BACKGROUND: This study aimed to determine the clinical outcomes, predictors of suboptimal functional improvement, and factors influencing patient satisfaction following conversion of a fused hip to total hip arthroplasty (THA). METHODS: A retrospective analysis of clinical and radiographic data was performed on 83 patients (83 hips) who underwent fused hip conversion to THA. Implant survival and predictors of poor functional outcome (Harris hip score < 70) were analyzed. In addition, factors associated with patient dissatisfaction (visual analog scale < 25th percentile) were analyzed in 63 patients (63 hips) who completed a patient-reported outcome measures questionnaire. RESULTS: The median Harris hip score improved from 55 (range, 18 to 77) to 78 (range, 36 to 100) at a mean follow-up of 10.2 ± 4.8 years (P < .001). Implant survival was 97.4% at 10 years and 91.3% at 20 years, with any revision as the endpoint. Multivariate analysis identified preoperative reliance on mobility aids as an independent predictor of poor functional outcome (P = .021). There were 48 of 63 patients (76%) satisfied (satisfaction visual analog scale ≥80) with the operated hip. Demographics and preoperative/postoperative clinical data did not differ between satisfied and unsatisfied patients. Among the patient-reported outcome measures, the Forgotten Joint Score-12 emerged as an independent discriminator of patient satisfaction. CONCLUSIONS: Conversion of a fused hip to THA provides functional improvement, favorable implant survival, and high patient satisfaction. However, patients dependent on mobility aids may experience suboptimal functional recovery, underscoring the need for careful preoperative counseling and patient selection.

BACKGROUND: There is major controversies surrounding the use and longevity of Pyrocarbon Interposition Shoulder Arthroplasty (PISA). The objective of this study was to investigate the long-term survival and outcomes (minimum 10-year) following PISA for osteoarthritis (OA) in young /active patients. METHODS: This was a retrospective review of prospectively collected data of patients who underwent PISA (InSpyre, Tornier-Stryker, USA) for OA between 2009 and 2012. Arthroplasty survival was known for 71 patients followed longitudinally for a minimum of 10 years. The clinical and radiological outcomes were assessed in 62 patients (62 shoulders) reviewed with radiographs. The mean age at surgery was 60 years (range, 23-72 years) and 31 shoulders (50%) underwent prior surgery before PISA. The diagnosis was primary osteoarthritis (POA=29), post-traumatic osteoarthritis (PTOA=23), post-instability osterarthritis (PIOA=10). Clinical failure was defined as repeat surgical intervention involving prosthesis revision. Clinical outcomes were assessed with Constant score (CS) and Subjective shoulder Value (SSV). The mean duration of follow-up was 11 ± 0.6 years (range, 10 to 14 years). RESULTS: Overall, the survival rate was 90% (95% CI: 82.8-96.8) at 5 years and 87% (95% CI: 79-94.8) at 10 years follow-up. Survival was 100% in PTOA (type 1 fracture sequelae) and in PIOA as well as 95% in primary OA with type-A glenoid. Revision surgery was significantly higher in biconcave (type-B2) glenoid (44%) compared to concentric (type-A) glenoid (2%), respectively (p=0.002). Among the 7 patients who were revised to RSA, 5 had painful glenoid erosion and 2 had bipolar (glenoid and humeral) erosion with thinning and finally fracture of the greater tuberosity (GT). Two shoulders with glenohumeral erosion were associated with secondary rotator cuff tears (one supraspinatus and one subscapularis tear). The mean time to revision and revision was 4 ± 1.7 years. Glenoid wear was more often superior (81%) than central (19%), p<0.001. For those shoulders not revised, the mean CS and SSV significantly increased from 39 ±14 to 70 ±14 points and 34% ±15 to 75% ±17, respectively (p<0.001). CONCLUSION: PISA is an efficient and durable surgical procedure for the treatment of young/active patients with post-traumatic OA, post-instability OA, and primary OA with concentric (type A) glenoid erosion, but not for those with biconcave (type B2) glenoid. Biconcave (type B2) glenoid and subscapularis tear or insufficiency are risk factors for failure and revision.
RESUMEN
Objective: The objective is to compare and evaluate the hard and soft tissue parameters by using short and standard long implants with sinus lifting in the posterior maxilla. Materials and Methods: Eleven patients with complaints of missing upper back teeth were enrolled in the study for implant-supported rehabilitation and were categorized into two groups: Group long (GL): longer implant (>8 mm) placement, preceded by Sinus Augmentation. Group short (GS): short implant (≤8 mm) placement, without sinus augmentation. The primary outcome measured was cumulative survival rate (CSR) in the compromised partial edentulous posterior maxilla. Secondary outcomes measured were implant stability (IS), marginal bone level alterations (MBL), pocket probing depth (PPD), crown-to-implant ratio, and any complications. Results: The difference in CSR between the groups was not statistically significant (P = 0.317). High stability was achieved immediately after the placement of the implants, in both groups (GS: 64 ± 4.07, GL: 65.58 ± 9.75); this difference in the mean ISQ (IS quotients) values was not found to be statistically significant at implant placement (P = 0.7). The mean MBL reported in the study at the end of 12 months of prosthesis function was - 0.762 ± 0.48 mm and - 0.7 ± 0.34 mm for GS and GL, respectively. The mean PPD measurements in GS and GL groups were 1.917 ± 0.68 mm and 1.833 ± 0.38 mm, respectively, and it was not statistically significant (P = 0.8). Conclusion: Within the limitations of the present study, the obtained results indicate that short implants provided a similar clinical and radiographic performance compared to long implants placed in combination with a sinus augmentation procedure (lateral window) up to 12 months after prosthetic loading.
RESUMEN
Background/Objectives: Short-stem prostheses were introduced as an alternative to conventional straight-stem prostheses. Despite their benefits, including minimally invasive approaches, soft-tissue- and bone-sparing implantation, and physiological load transfer to the metaphysis, data on postoperative complication and revision rates as well as on implant survival are scarce. Methods: A retrospective analysis of 1327 patients who underwent primary total hip arthroplasty (THA) using the Metha® short stem between 2006 and 2023 was conducted. Complication and revision rates were analysed for the intraoperative, direct postoperative, and follow-up episodes. Implant survival was analysed with the endpoint of all-cause stem revision. Results: Intraoperative complications were observed in 3.77% of the cases and included 44 hairline cracks and 6 fractures. In 15 cases (30.0%), conversion to a straight-stem or revision implant was necessary. The direct postoperative complication rate was 2.44%, and 11 revision procedures were performed during inpatient stay (0.84%). Mean follow-up was 7 years (range 1-17). During follow-up, femoral component revision was performed in 60 cases. Aseptic loosening and stem subsidence accounted for a combined percentage of 80% of all indications. Implant survival rate was 95.66% after 5 years, 95.58% after 10 years, and 95.50% after 15 years. Conclusions: Our study provides a comprehensive analysis of postoperative complication and revision rates in a large sample undergoing primary short-stem THA. Postoperative complication rates were favourable, and the long-term implant survival rates were comparable to conventional straight-stem prostheses. Therefore, short-stem THA may be considered an alternative for younger patients.
RESUMEN
BACKGROUND: Total hip arthroplasty (THA) is a common procedure that requires consideration of preexisting comorbidities. Factor V Leiden (FVL), an inherited thrombophilia, is one such condition that predisposes patients to venous thromboembolism (VTE, deep vein thrombosis, and pulmonary embolism). The present study aimed to characterize the risks associated with FVL patients undergoing THA and evaluate the effect of VTE chemoprophylactic agents on these risks. METHODS: A total of 544,022 adult patients who underwent primary THA for osteoarthritis indications between 2010 and October 2021 were identified in an administrative claims database. Of these, FVL was identified in 1,138 (0.21%). Patients who had and did not have FVL were matched at a 1:4 ratio (1,131 with FVL and 4,519 without FVL) based on age, sex, and Elixhauser comorbidity index. Univariable and multivariable analyses were assessed for 90-day complications. Implant survival at 5 years was assessed and compared with log-rank tests. The relative use of different chemoprophylactic agents, including aspirin, warfarin, heparin, or direct oral anticoagulant (DOAC), was assessed. Bleeding events and VTE were compared for those prescribed either aspirin or warfarin, heparin, or DOAC. A Bonferroni correction was applied. RESULTS: On multivariable analysis, FVL patients were found to have increased odds of 90-day deep vein thrombosis (odds ratio (OR) = 9.20), pulmonary embolism (OR = 6.89), and aggregated severe and all adverse events (OR = 4.74 and 1.98, respectively), but not elevated risk of other perioperative adverse events or 5-year reoperations. More potent chemoprophylactic agents (warfarin, heparin, DOAC) reduced, but did not completely eliminate, the increased VTE risks (without increasing bleeding events). CONCLUSIONS: This study quantified the significantly elevated VTE risk associated with FVL patients undergoing THA. The lack of difference in other specific adverse events and 5-year reoperations is reassuring. Clearly, chemoprophylactic agents are important in this population and may need further attention.

The purpose of this paper was to retrospectively assess the local factors that are likely to be associated with the risks for one-year dental implant loss.A retrospective study was designed and implemented. The sample consisted of patients who underwent an implant loss or removal caused by peri-implantitis or infection after prosthesis loading. The chi-squared test and generalised estimating equations (GEE) were used to explore the potential risk factors for one-year implant loss. A total of 279 patients with 287 failed implants were enrolled in this study. Immediate implant placement exhibited a 3.373 (95% CI: 1.652 to 6.886) significantly increased risk to experience one-year implant loss than early and late implant placement (p = 0.001). In addition, implants loaded during a healing period fewer than two months after implant placement were at 18.139 (95% CI: 8.925 to 36.866) significantly higher risk of one-year implant loss when compared with those that loaded within more than two months after implant placement (p < 0.001). Smokers were 1.866 (OR = 1.866,95% CI: 0.993 to 3.510) times as high risk for one-year implant loss as non-smokers, but there were no significant statistical differences (p = 0.053). Immediate implant placement and early implant loading were considered risk factors for one-year implant loss.

OBJECTIVE: This study aims to collect data on implant survival, bone volume maintenance, and complications associated with the socket shield technique. BACKGROUND DATA: The socket shield technique was introduced in 2010. Since then, several systematic reviews have been published, showing good clinical outcomes. The behaviour of the buccal bone plate is so far not completely understood. METHODS: The study involved the placement of 23 implants using the socket shield technique in 20 patients. AstraTech EV implants were used, and no bone substitutes or connective tissue grafts were applied. Patients were monitored for 18 months, recording implant survival, volumetric bone analysis on CBCT scans, interproximal bone levels, bone sounding, pink esthetic scores, and complications. Prosthetic procedures were also described, including temporary and final restorations. RESULTS: A 95.7% cumulative 18-month implant survival rate was obtained using the socket shield technique, with a significant but limited reduction in buccal bone thickness (BBT) after implant placement. One implant did not integrate and two shields were partially exposed. The mean pink esthetic score, 1 year after loading was 12.93 ± 1.22. CONCLUSION: The study suggests that the socket shield technique can result in limited reduction of the buccal bone volume, with a high implant survival rate. Re-entry studies are recommended to investigate the causes of bone resorption.
RESUMEN
PURPOSE: The objective of the present systematic review and meta-analysis was to assess randomised controlled trials (RCTs) which assessed the efficacy of mini dental implants (MDIs) and standard-diameter implants (SDIs) in retaining mandibular overdentures (MO). MATERIALS AND METHODS: The focused question was "Is there a difference in the mechanical stability between MDIs and SDIs in retaining MO?" Indexed databases were searched up to and including November 2023 using different keywords. Boolean operators were used during the search. The literature was searched in accordance with the PRISMA guidelines. The PICO characteristics were: patients (P) = individuals with complete mandibular dentures requiring dental implants; Intervention (I) = placement of MDIs under mandibular dentures; Control (C) = placement of SDIs under mandibular dentures; Outcome (O) = comparison of stability between MDIs and SDIs in supporting mandibular dentures. Only RCTs were included. Risk of bias (RoB) was assessed using the Cochrane RoB tool. RESULTS: Five RCTs were included. The numbers of participants ranged between 45 and 120 edentulous individuals wearing complete mandibular dentures. The mean age of patients ranged between 59.5 ± 8.5 and 68.3 ± 8.5 years. The number of MDIs and SDIs ranged between 22 and 152 and 10 and 80 implants, respectively. The follow-up duration ranged between one week and 12 months. Three RCTs reported an improvement in the quality of life (QoL) of all patients after stabilisation of mandibular dentures using MDIs or SDIs. In one RCT, peri-implant soft tissue profiles were comparable between MDIs and SDIs at the 1-year follow-up. The implant survival rate was reported in two RCTs, which were from 89% to 98% and 99% to 100% for MDIs and SDIs, respectively. All RCTs had a low RoB. CONCLUSION: Mini dental implants represent a viable alternative to traditional standard-diameter implants when seeking optimal retention for mandibular overdentures.

Total hip arthroplasty (THA) is the mainstay therapy for patients with terminal hemophilic arthropathy of the hip. However, the largest case series published between 2017 and 2023 in the literature on THA in patients with hemophilia have found a higher 1-year infection rate (8.1% versus 3.4%) in hemophilia patients than in the general population, a higher rate of in-hospital bleeding complications (38.7% versus 16.1%), a higher length of stay (6 days versus 3 days) and a higher 30-day readmission rate (22.6% versus 4.1%). Finally, a lower 5-year survival rate has also been observed in hemophilia patients than in the general population (91.9% versus 95.3%). In the last decade there have been dramatically positive improvements in implant designs and hematological treatment, and therefore it does not seem that THA in hemophilia is so far from that in osteoarthritic patients.
RESUMEN
Introduction: A recent study has demonstrated that social factors have an impact on the condition of dental implants. The present investigation investigated how varied alcohol intake quantities might alter the condition of dental implants and related peri-implant inflammation. Materials and Methods: This retrospective research was piloted in a tertiary care center, and implants inserted between 2010 and 2022 were evaluated through a retrospective cohort analysis. Within 3 months following implant implantation, information on alcohol intake was gathered from the health maintenance records and employed as the predictor variable. The implant results as well as peri-implantitis were examined at follow-up visits. Using the logistic regression model, the Wald test analysis analyzed the statistical consequences of each parameter. The findings were translated using an odds ratio that was determined with a 95% confidence level. The data were generated and analyzed using descriptive statistics, with statistical significance defined as P < 0.05. Results: At the time of implant placement, the enrolled patients were 59 ± 11.3 years old on average. The median time before peri-implantitis occurred was 31.3 ± 22.2 months. Within the first 2 years following implant implantation, the majority of people experienced peri-implantitis. The incidence of peri-implantitis was the lowest among light and moderate alcoholics (11.5%) and the highest among heavy alcoholics (46.2%). Moderate alcohol use was associated with a 79.1% decrease in peri-implantitis when compared to not drinking (P = 0.0365), whereas light alcohol consumption was connected to a 51.3% decrease (P = 0.026). The incidence of peri-implantitis among heavy drinkers was significantly significant (P = 0.0001). Conclusion: According to the findings of the current retrospective cohort analysis, drinking alcohol at mild-to-moderate levels is connected to a reduction in the incidence rate of peri-implantitis compared to heavy drinkers. In contrast, high alcohol consumption was found to be associated with an increase in the prevalence of peri-implantitis among the participants who had dental implants.
RESUMEN
Background: This study aims to compare the long-term success rates of immediate implant placement and delayed implant placement in patients with periodontally compromised teeth. Materials and Methods: A total of 30 patients presenting with periodontally compromised teeth requiring extraction and subsequent implant placement were enrolled in this retrospective study. Patients were divided into two groups based on the timing of implant placement: Group A (immediate implant placement) and Group B (delayed implant placement). Implants were placed according to standard protocols. Patient records were reviewed for implant survival, peri-implant bone loss, and prosthetic complications. Data were statistically analyzed using appropriate tests. Results: The mean follow-up period was 5 years. In Group A, the implant survival rate was 90%, while in Group B, it was 83%. The mean peri-implant bone loss was 1.5 mm in Group A and 2.2 mm in Group B. Prosthetic complications were observed in three cases in Group A and five cases in Group B. The differences in implant survival and bone loss between the two groups were not statistically significant (P > 0.05). Conclusion: Both immediate implant placement and delayed implant placement demonstrated comparable long-term success rates in patients with periodontally compromised teeth.
RESUMEN
Objectives: It is commonly accepted that immediate implantation is the best option for patients since it shortens the time patients must wait for ultimate restoration and provides a predictable functional and aesthetic result. However, this approach is still controversial in patients with apical pathosis. The goal of this systematic review and meta-analysis was to determine the efficacy of immediate implant insertion in patients with apical pathosis. Material and methods: Between 2000 and 2023, PRISMA-compliant keywords were used to search PubMed, MEDLINE, CENTRAL, and the Cochrane Library. All English-language clinical studies that met PICOS criteria were included in a manual search. The included studies' demographic profile and event data for immediate dental implantation success in patients with or without apical pathosis were meta-analyzed using RevMan. The implant survival rate was assessed using risk ratio of plaque index and bleeding index. Begg's test using MedCalc and RevMan risk of bias assessment assessed publication bias. Results: A meta-analysis of 10 trials with 849 dental implantation patients found a substantial difference in initial implant placement success rates in infected sites. The pooled risk ratio for plaque index is 0.59 (95% CI: 0.36-0.96) with heterogeneity of Tau2 = 0.62, chi2 = 109.69, df = 11, I2 = 90%, z = 2.12, and p < 0.05. While, the pooled risk ratio for bleeding index is 0.77 (95% CI: 0.60 to 0.98) with Tau2 = 0.16, chi2 = 103.67, df = 11, I2 = 89%, z = 2.12, and p < 0.05. The pooled odds ratio of implant survival rate is 2.08 (95% CI: 1.56 to 1.79) with Tau2 0.16; chi2 52.43; df 9; I2 83%; z 4.93 and p < 0.05. As evidenced by the funnel plot and statistically insignificant Begg's test p values of 0.45. Conclusion: The placement of immediate implants in locations affected by apical pathosis is a clinically beneficial surgery, resulting in favorable aesthetic and functional outcomes for patients.
RESUMEN
OBJECTIVES: To compare the clinical and radiological outcomes of novel fully tapered tissue-level implants in immediate implant placement (type 1) versus late implant placement (type 4) for the first time. MATERIALS AND METHODS: For this clinical study, 318 fully tapered tissue-level implants in 65 patients were inserted immediately (n = 68 implants) or late (n = 250 implants) in two different centers. Implant survival and success rates and marginal bone levels were analyzed. RESULTS: After a mean follow-up of 12.0 ± 5 months, implant survival rates were 97.8% for all implants. No statistically significant difference in implant survival rates between type 1 and type 4 could be detected (98.5% vs 97.6%, HR 0.70, 95%-CI 0.084-5.81). Neither for implant length (HR 0.53, 95%-CI 0.055-5.08) nor for implant width (HR 0.27, CI 0.028-2.55), a significant influence on implant survival could be detected. Type of used biomaterial for filling the gap and immediate loading showed no effect on implant survival. Mean marginal bone loss was 0.02 ± 0.05 mm for type 1 and 0.04 ± 0.1 for type 4. CONCLUSIONS: Within the limitations of this retrospective study and the short follow-up, the results demonstrated comparable high survival and success rates and stable marginal bone levels for type 1 and type 4 placement of this novel tissue-level implant (no clinical trial registration as retrospective study design).
