RESUMO

BACKGROUND: This single-centered randomized controlled clinical trial aimed to evaluate the effectiveness of micro-osteoperforations (MOPs) in accelerating the orthodontic retraction of maxillary incisors. METHODS: Forty-two patients aged 16-40 were recruited and randomly assigned into two groups, one which underwent MOPs (MOPG) in the buccal and palatal region of all maxillary incisors immediately before the start of retraction and one which did not (CG). Eligibility criteria included the orthodontic need for maxillary first premolars extraction and space closure in two phases. The primary outcome of the study consisted of measuring the rate of space closure and, consequently, the rate of incisors' retraction using digital model superimposition 14 days later and monthly thereafter for the next 4 months. The secondary outcomes included measuring anchorage loss, central incisors' inclination, and root length shortening, analyzed using cone beam computed tomography scans acquired before retraction and 4 months after retraction. Randomization was performed using QuickCalcs software. While clinical blinding was not possible, the image's examinator was blinded. RESULTS: Twenty-one patients were randomly assigned to each group. However, due to various reasons, a total of 37 patients (17 male and 20 female) were analyzed (mean age: 24.3 ± 8.1 years in the MOPG; 22.2 ± 4.2 years in the CG) during the trial. No statistically significant difference was found between the MOPG and the CG regarding the incisors' retraction measured at different time points at the incisal border (14 days, 0.4 mm vs. 0.5 mm; 1 month, 0.79 mm vs. 0.77 mm; 2 months, 1.47 mm vs. 1.41 mm; 3 months, 2.09 mm vs. 1.88 mm; 4 months, 2.62 mm vs. 2.29 mm) and at the cervical level (14 days, 0.28 mm vs. 0.30 mm; 1 month, 0.41 mm vs. 0.32 mm; 2 months, 0.89 mm vs. 0.61 mm; 3 months, 1.36 mm vs. 1.10 mm; 4 months, 1.73 mm vs. 1.39 mm). Similarly, no statistically significant differences were detected in the space closure, anchorage loss, central incisors' inclination, and radicular length between groups. No adverse effect was observed during the trial. CONCLUSIONS: MOPs did not accelerate the retraction of the maxillary incisors, nor were they associated with greater incisor inclination or root resorption.

RESUMO

Background: Mini-implants are devices used to provide absolute and temporary anchorage for tooth movement. Objectives: The present study was carried out to compare the use of periapical radiographs and computed tomography (CT) for planning mini-implants performed by orthodontists. Material and Methods: Five radiographs and five CT scans of premolars and molars regions. These were analyzed by ten Orthodontists. Initially (T1), the evaluators indicated the preferred location for the insertion of a mini-implant, as well as the diameter and length of the device, using only a periapical radiograph. After 30 days (T2), the same evaluation was performed. Sixty days later (T3), the orthodontists reassessed the radiographs in association with the CT scans. Finally, after 90 days (T4), the evaluation was performed with the same exams. The comparison of the chosen diameter and length of the mini-implants was performed using the Student's t-test. The evaluation of the chosen insertion sites was analyzed by the Wilcoxon test. For both tests, the level of significance was 5%. The kappa concordance test was also performed for the intra- and inter-examiner evaluations. Results: The results of the study showed substantial or perfect intra-examiner and reasonable to perfect inter-examiner agreement. Considering the length and diameter of the mini-implants, no statistical difference was found between the groups. Regarding the insertion site, more than 20% of the treatment plans were changed when the CT scan was associated. Conclusions: The results showed that the association of a CT scan with radiography frequently leads the professional to change the insertion point for the installation of mini-implants.

RESUMO

The topical glucocorticoid budesonide has been prescribed before and after sinus lift surgery as adjuvant drug treatment for maxillary sinus membrane inflammation. However, there is no study on the effects of budesonide on the regenerative process of bone grafting biomaterials. We investigated the effect of the association of budesonide with some biomaterials on the growth and differentiation capacity of pre-osteoblastic cells (MC3T3-E1 subclone 4). Xenogeneic (Bio-Oss and Bio-Gen) and synthetic hydroxyapatites (Osteogen, Bonesynth, and HAP-91) were tested in conditioned medium (1% w/v). The conditioned medium was then supplemented with budesonide (0.5% v/v). Cell viability was assessed using the MTT assay (48, 96, and 144 h), and mineralized nodules were quantified after 14 days of culture using the Alizarin Red Staining. Alkaline phosphatase activity was assessed through the release of thymolphthalein at day seven. All biomaterials showed little or no cytotoxicity. The Bio-Gen allowed significantly less growth than the control group regardless of the experimental time. Regarding differentiation potential of MC3T3-E1, the HAP-91-conditioned medium showed remarkable osteoinductive properties. In osteodifferentiation, the addition of budesonide favored the formation of mineral nodules when cells were cultured in medium conditioned with synthetic materials, whereas it weakened the mineralization potential of cells cultured in xenogeneic medium. Regardless of whether budesonide was added or not, Osteogen and Bio-Oss showed higher alkaline phosphatase activity than the other groups. Budesonide may improve bone formation when associated with synthetic biomaterials. Conversely, the presence of this glucocorticoid weakens the mineralization potential of pre-osteoblastic cells cultured with xenogeneic hydroxyapatites.

RESUMO

PURPOSE: This study aimed to evaluate changes of the alveolar bone and interdental bone septum of the mandibular incisors through cone-beam computed tomography (CBCT) after orthodontic treatment of mandibular dental crowding without dental extraction. MATERIALS AND METHODS: The sample consisted of 64 CBCT images (32 pre-treatment and 32 post-treatment) from 32 adult patients with class I malocclusion and an average age of 23.0±3.9 years. The width and height of the alveolar bone and interdental septum, the distance between the cementoenamel junction (CEJ) and the facial and lingual bone crests, and the inclination of the mandibular incisors were measured. RESULTS: The distance between the CEJ and the marginal bone crest on the facial side increased significantly (P<0.05). An increased distance between the CEJ and the bone crest on the facial and lingual sides showed a correlation with the irregularity index (P<0.05); however, no significant association was observed with increasing mandibular incisor inclination (P>0.05). The change in the distance between the CEJ and the marginal bone crest on the facial side was correlated significantly with bone septum height (P<0.05). CONCLUSION: Bone dehiscence developed during the treatment of crowding without extraction only on the incisors' facial side. Increasing proclination of the mandibular incisor was not correlated with bone dehiscence. The degree of dental crowding assessed through the irregularity index was associated with the risk of developing bone dehiscence. The interdental septum reflected facial marginal bone loss in the mandibular incisors.

RESUMO

BACKGROUND: Regardless of the kind of biomaterial used for the graft, it is clear that, over time, the graft undergoes dimensional changes that could influence the final bone volume obtained, which could alter the stability of the installed implants. The aim of the present study was to compared and correlated the graft behavior with the amount (in grams) of xenogeneic and alloplastic biomaterials used in grafts for maxillary sinus lift. MATERIAL AND METHODS: This retrospective cohort study used 148 CBCT images of 74 grafts from 68 maxillary sinuses lift patients in a university, post-graduate clinic. The weights of biomaterials, categorized in intervals according to amount used, were correlated with the graft volumes at V1 (10 days) and V2 (180 days). Kruskal-Wallis test was used to evaluate the possible bias effect of weight on graft maintenance. RESULTS: Mean weights of biomaterials used were: Bio-Oss Small® (1.58g); Bio-Oss Large® (1.35g); Endobon® (0.72g); BoneCeramic®+Emdogaim® (0.96g); Cerasorb® (1.13g) and Osteogen® (2.70g). No significant differences (p>0.05). Were found for the influence of these mean amounts in graft maintenance: Bio-Oss Small® (18); Bio-Oss Large® (10); Endobon® (17); BoneCeramic®+Emdogaim® (10); Cerasorb® (11); and Osteogen® (08) at V1 and V2. However, when biomaterials were categorized by intervals, all Cerasorb® interval groups showed statistically significant differences (p<0.001) in graft volume at V2. CONCLUSIONS: The amounts of the biomaterials used could influence the final volume; depending on the biomaterial characteristics. Implant installation was possible with all studied grafts, although graft volume shrinkage should be considered when selecting biomaterial for sinus lift.

RESUMO

Rehabilitation of patients through implants in areas with severe bone resorption in the posterior mandible is a challenge in implant dentistry. In this context, extra short implants configure a treatment option for this type of patient, as they can avoid increased financial cost, treatment time and patient morbidity. The present study evaluated the marginal bone stability in individualized extra-short implants for masticatory function in the posterior mandible. Using digitized periapical radiographs of 13 extra-short implants performed on 7 patients. The mesial and distal regions of each implant were selected, from the bone crest to the region parallel to the apex, and the bone stability of this crest was measured using the Image J software immediate T1 and 1 year after rehabilitation (T2). The height of the bone crest remained stable, showing no statistically significant difference between T1 and T2 (p> 0.005) for both the mesial bone crest and the distal bone crest in individual or united crowns rehabilitation. Marginal bone stability was observed in extra short implants, corroborating the biological and biomechanical stability of these implants presented in the literature. Despite the limited sample size and proservation time, extra-short implants are predictive treatment options for patients with severe bone atrophy in the posterior mandible. Key words:Extra-short implants, marginal bone loss, mandibular bone atrophy.

RESUMO

ABSTRACT The replacement of missing teeth by implant retained prostheses is a predictable form of rehabilitation in the population as a whole. Due to thesimilarity between periodontal disease and peri-implantitis, the hypothesis is inferred that patients with a history of periodontal disease would be more susceptible to peri-implantitis. This concept has been discussed and supported by new scientific evidence. The purpose of this review was to evaluate whether there is any relationship between periodontitis and greater peri-implant bone loss in periodontally compromised patients. The pertinent literature has concluded that rehabilitation by means of implants in patients with a history of periodontal disease was predictable and has shown success rates similar to those obtained in patients with no history of periodontitis.

RESUMO A substituição dos dentes ausentes, por próteses implanto retidas, é uma forma previsível de reabilitação na população como um todo. Devido à similaridade da doença periodontal com a periimplantite, infere-se a hipótese de que pacientes com histórico de doença periodontal seriam mais suceptíveis a periimplantite. Este conceito vem sendo discutido e suportado por novas evidencias científicas.O objetivo desta revisão é avaliar se pacientes historicamente periodontalmente comprometidos apresentam relação com maior perda óssea peri-implantar. A literatura pertinente conclui que a reabilitação por meio de implantes em pacientes com histórico de doença periodontal é previsível e com índice de sucesso semelhantes pacientes sem histórico de periodontite.

RESUMO

O desvio de septo nasal, concha bolhosa e a obstrução do óstio são alterações do complexo osteomeatal, que podem interferir no volume dos seios maxilares, em sua oxigenação, drenagem adequada de fluidos e nos resultados de cirurgias nessa região. A adoção de um protocolo de avaliação do complexo osteomeatal envolvendo uma equipe multidisciplinar no planejamento de cirurgias de levantamento de seio maxilar pode proporcionar a diminuição do surgimento de complicações pós-operatórias relacionadas à drenagem e ventilação, prejudicadas pelo desvio de septo nasal, concha bolhosa e obstrução do óstio.

Nasal septum deviation, concha bullosa and ostium obstruction are alterations of the osteomeatal complex that may interfere with the volume of the maxillary sinuses, their oxygenation, adequate drainage of fluids and the results of surgeries in this region. The adoption of a protocol for evaluation of the osteomeatal complex involving a multidisciplinary team in the planning of surgeries of maxillary sinus can provide a reduction in the appearance of postoperative complications related to drainage and ventilation impaired by nasal septum deviation, concha bullosa and obstruction of the ostium.

RESUMO

This study aimed to compare the primary and secondary stability, measured by resonance frequency analysis (RFA), in implants of different lengths installed in areas submitted to maxillary sinus lift. Correlation between RFA and implant insertion torque was also assessed. Twenty implants of 9 and 11 mm were inserted in areas submitted to maxillary sinus lift. The insertion torque was measured by the Bien Air motor. Osstell, through RFA, determined the implant stability quotient (ISQ) 2 times: the day of implant installation (T1) and 90 days after implant installation (T2). No differences were observed in the ISQ between T1 and T2 when the 20 implants were grouped, nor when the 9 mm implants were evaluated separately. In contrast, when the 11 mm values were evaluated separately, the ISQ was significantly higher in T2 than in T1 ( P < .05). In T1, 9 mm implants had a higher ISQ than 11 mm ones ( P < .05), whereas in T2, the implants of 11 mm showed a higher ISQ than did the 9 mm implants ( P < .05). There was no difference in insertion torque between 9 and 11 mm implants ( P > .05), nor was there a correlation between ISQ and insertion torque ( P > .05). In conclusion, longer implants (11 mm) presented a significant increase in ISQ values during the healing period when installed in areas previously submitted to maxillary sinus lift. This phenomenon was not observed for shorter implants (9 mm). Finally, no correlation was observed between ISQ and insertion torque.

RESUMO

OBJECTIVE: Using computed tomography, to compare vertical and volumetric bone augmentation after interposition grafting with bovine bone mineral matrix (GEISTLICH BIO-OSS® ) or hydroxyapatite/tricalcium phosphate (STRAUMANN® BONECERAMIC) for atrophic posterior mandible reconstruction through segmental osteotomy. MATERIAL AND METHODS: Seven patients received interposition grafts in the posterior mandible for implant rehabilitation. The computed tomography cone beam images were analysed with OsiriX Imaging Software 6.5 (Pixmeo Geneva, Switzerland) in the pre-surgical period (T0), at 15 days post-surgery (T1) and at 180 days post-surgery (T2). The tomographic analysis was performed by a single trained and calibrated radiologist. Descriptive statistics and nonparametric methods were used to analyse the data. RESULTS: There was a significant difference in vertical and volume augmentation with both biomaterials using the technique (P < 0.05). There were no significant differences (P > 0.05) in volume change of the graft, bone volume augmentation, or augmentation of the maximum linear vertical distance between the two analysed biomaterials. CONCLUSIONS: The GEISTLICH BIO-OSS® and STRAUMANN® BONECERAMIC interposition grafts exhibited similar and sufficient dimensional stability and volume gain for short implants in the atrophic posterior mandible.

RESUMO

OBJECTIVE: : The composition and morphology of the internal and external surfaces of membranes are important for preventing migration of epithelial and connective cells, and allow the installation of osteogenic cells for bone growth. The objective of this study was to analyze the morphology and composition of three types of commercially available resorbable collagen membranes. METHODS: Three types of collagen membranes, with different compositions and coming from different animals, were used: 1) Dental Surgidry F (bovine collagen type I); 2) Bio-Gide® (porcine collagen type I and III); and 3) OsseoGuard™ (bovine collagen type I). These membranes were analyzed using scanning electron microscopy and energy dispersive spectrometry. RESULTS: The membranes showed distinct superficial architectures, porosities and chemical compositions. The membranes exhibited different surfaces and thicknesses, ranging from 0.32 mm to 0.75 mm. The chemical compositions exhibited a high percentage of niobium (Nb) in the Surgidry and OsseoGuard™ membranes; the Bio-Gide® membrane showed a greater proportion of calcium and aluminum relative to other elements. CONCLUSION: Different types of resorbable collagen membranes exhibit different morphologies and chemical composition, which could lead to differences in the mode and time of resorption of the membranes used for guided tissue regeneration procedures.

RESUMO

OBJECTIVE: This study aimed to evaluate the effect of initial periodontal clinical parameters on the final outcome of the treatment of periodontal recessions by means of a coronally positioned flap (CPF). MATERIALS AND METHODS: The CPF technique was used in a total of 39 Miller Class I/II gingival recessions of the upper canines and/or premolars. The clinical periodontal parameters evaluated were: probing depth, gingival recession height, gingival recession width, keratinized mucosa, attached keratinized mucosa, flap thickness and free gingival margin thickness. The degree of root coverage was evaluated 6 months and 1 year after the surgery. The data were analyzed by Student's t-test, Mann-Whitney and Pearson's correlation tests, as well as linear regression. RESULTS: A significant reduction in gingival recession height, gingival recession width, keratinized mucosa, and attached keratinized mucosa were observed. A significant negative correlation was found between gingival recession and root coverage percentage at 1 year, and a significant negative correlation between gingival margin thickness and coverage percentage at 1 year. The gingival recession and flap thickness significantly predicted the amount of root coverage. CONCLUSIONS: The initial dimensions of gingival recession and the mucosa thickness were correlated to the percentage of root coverage. The gingival recession width was the major predictor of root coverage.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the influence of periodontal clinical parameters on the treatment of gingival recession by means of a coronally positioned flap (CPF). MATERIALS AND METHODS: In this clinical study, the coronally positioned flap technique was used in a sample of 14 individuals with Miller's Class I or II gingival recession of the canines and/or maxillary premolars, totaling 39 recessions. The clinical periodontal parameters evaluated were: probing depth (PD), gingival recession height (GRH), gingival recession width (GRW), clinical attachment level (CAL), keratinized mucosa (KM), attached keratinized mucosa (AKM), gingival thickness (GT) and free gingival margin thickness (GMT). The degree of root coverage was evaluated 3 months after the surgical procedures were performed. The data were analyzed using Student's-t, Mann-Whitney and Pearson's correlation tests, as well as the Cohen's d. RESULTS: After root coverage, there was no significant change in PD. Significant reductions in GRH and GRW were observed. In addition, a significant reduction in KM and AKM, and an increase in GMT were also observed. A significant negative correlation was found between initial GMT and gingival recession at 3 months, and a significant negative correlation between GT and periodontal recession at 3 months. There was large effect size for GRH, GRW, CAL, KM, AKM and GMT parameters. CONCLUSIONS: The initial gingival recession height, keratinized mucosa and free gingival margin thickness were the parameters that had the most influence on root coverage by the coronal sliding flap technique.

RESUMO

Dental anatomy is quite complex and diverse factors must be taken into account in its analysis. Teeth with anatomical variations present an increase in the rate of severity periodontal tissue destruction and therefore a higher risk of developing periodontal disease. In this context, this paper reviews the literature regarding enamel pearls and their implications in the development of severe localized periodontal disease as well as in the prognosis of periodontal therapy. Radiographic examination of a patient complaining of pain in the right side of the mandible revealed the presence of a radiopaque structure around the cervical region of lower right first premolar. Periodontal examination revealed extensive bone loss since probing depths ranged from 7.0 mm to 9.0 mm and additionally intense bleeding and suppuration. Surgical exploration detected the presence of an enamel pearl, which was removed. Assessment of the remaining supporting tissues led to the extraction of tooth 44. Local factors such as enamel pearls can lead to inadequate removal of the subgingival biofilm, thus favoring the establishment and progression of periodontal diseases.

RESUMO

The aim of the present study was to review the literature regarding the utilization of 2-octyl cyanoacrylate's (Dermabond®, Ethicon US, USA) as a tissue adhesive in dentistry; also, to report its use in the stabilization and fixation of a free gingival graft, indicated to increase the width of the keratinized attached mucosa at the lower incisive region. Literature analysis revealed numerous indications for this tissue adhesive in the medical field related to maxillofacial injuries. In dentistry, clinical reports, as well as controlled clinical studies conducted in humans and in animal models, using histological analysis described positive results for the use of different cyanoacrylate-based tissue adhesives. These studies reported that the use of tissue adhesives reduced the surgical procedure time period, eliminated postoperative visits as well as the discomfort of suture removal and, in addition, did not interfere with the clinical repair process. Favorable results, like the ones described in the literature, were obtained in the present case report using Dermabond®.

O objetivo do presente estudo foi revisar a literatura pertinente sobre a utilização do 2-octil cianoacrilato (Dermabond®, Ethicon US, USA) como adesivo tecidual na Odontologia, assim como relatar seu uso na estabilização e fixação de um enxerto gengival livre indicado para aumento da mucosa ceratinizada inserida na região dos incisivos inferiores. A análise da literatura revelou ampla aplicabilidade deste adesivo tecidual na área médica relacionada aos ferimentos maxilofaciais. Na Odontologia existem relatos clínicos e estudos controlados em humanos e em modelos animais, descrevendo resultados positivos, inclusive por meio da análise histológica, sobre a utilização de diferentes adesivos teciduais, à base do cianocrilato. Estes estudos relataram que o uso dos adesivos teciduais, reduz o tempo operatório, elimina visitas pós-operatórias, não apresenta o desconforto da remoção de suturas, além de não interferir no processo de reparo clínico. Resultados favoráveis como os descritos na literatura, foram obtidos no presente relato de caso com a utilização do Dermabond®.

RESUMO

A recessão gengival é uma alteração comum que gera transtornos funcionais e estéticos nos indivíduos acometidos. Na busca por uma melhor resolução dessa condição, diversos métodos de tratamento têm sido desenvolvidos ao longo das últimas três décadas, sendo que, atualmente, as técnicas e os biomateriais regenerativos estão em evidência. O presente artigo é uma revisão da literatura científica, pertinente sobre o potencial clínico da utilização do derivado da matriz do esmalte, composto 90% por amelogeninas, no tratamento das recessões gengivais classes I e II de Miller.
