RESUMEN

Microstomia and orofacial contractures continue to garner interest regarding the effectiveness of treatment methodologies utilized to impact functional change. Oral splints are an accepted tool in the management of microstomia. However, the concepts of which oral splints to use, timing of initiation, and duration of treatment have not gained a consensus. This article reviews approaches to oral splinting and an alternative intraoral approach using splints designed to provide a graded, low load, multidirectional, and prolonged stretch specifically in facial burn survivors including those with mature scars. Two participants participated in a trial using oral splints placed inside the mouth at established contracture points. Participants were requested to use the splints for 1 h twice daily. Participants were photographed weekly producing 9 facial expressions, and distance between 13 facial landmarks was measured to evaluate change in tissue length. Numerical changes observed from beginning to end of the trial indicate positive and negative alterations, signifying lengthening or shortening of tissue. Negative changes denote reduction in distance between endpoints, while positive changes signify an increase. Participants verbalized functional improvements in oral motor and psychosocial function posttreatment. To date, oral splints can be custom fabricated for each individual patient. However, few oral splints are created to provide multidirectional stretch focusing on problem areas across the mid and lower face. The intraoral splints and regimen described here have the capability of providing a stretching intervention that could be applicable in various stages of burn recovery.

RESUMEN

Objective: We have used ultrasound imaging technology to objectively demonstrate changes in the degree and quality of diseased fascia in patients with Dupuytren's disease treated nonoperatively with therapeutic splinting and tissue mobilization. Materials and Methods: Measurement of active proximal interphalangeal and metacarpophalangeal joint extension along with ultrasound elastography imaging of the fascia was performed prior to, and 6 months after, the initiation of therapy. Results: Improvement in active joint extension over the course of therapy was associated with a consistent decrease in the radiologic dimensions of the diseased fascia in combination with qualitative changes in its composition. Conclusion: The use of a simple orthosis and soft tissue mobilization techniques have a quantifiable effect on the degree of deformity and the quantity and quality of contracted fascia in Dupuytren's disease, and would appear to have a role in the management of mild to moderate presentations of the disease when enzymatic or surgical interventions may not be practical.

RESUMEN

OBJECTIVE: Aim: To study the specifics of the impact of immediate intraoperative loading with a splinting component on supporting tissues during a one-stage implantation protocol. PATIENTS AND METHODS: Materials and Methods: In the course of the study, orthopedic treatment was carried out for 55 patients aged 29 to 60 years. The following were performed: cone-beam computed tomography, software planning and intraoral scanning with an optical scanner, one-stage implantation protocol, assessment of implant stability with the Osstell ISQ device, microcirculation study in the peri-implant area using laser Doppler flowmetry (LDF). RESULTS: Results: It was established that around loaded implants there is an increase in blood flow and vasomotor activity of the microcirculatory channel of the supporting tissues, an increase in the volume of bone tissue and an increase in torque, which is the optimal forecast for the acceleration of the pace of osseointegration. CONCLUSION: Conclusions: The use of a splinting component during immediate intraoperative functional masticatory load accelerates the dynamics of bone tissue remodeling processes around the implant, which is an optimal prediction of osseointegration rates in various dental implantation protocols and is consistent with high values of the implant stability coefficient.

RESUMEN

External nasal splints are commonly used for immobilization following nasal fracture reduction or rhinoplasty procedures. The literature documents the use of various materials like thermoplastic materials, aluminum, Orthoplast, fiberglass, plaster of Paris, and polyvinyl siloxane. These materials are bulky, time-consuming, expensive, and cumbersome to use, and have been associated with complications including contact dermatitis and epidermolysis. Furthermore, they cannot be retained if the situation warrants prolonged stabilization and immobilization. We introduce a new technique using readily available scalp vein catheter flanges as an external nasal stent. The technique is easy to master, inexpensive, and limits edema and ecchymosis, while stabilizing the reconstructed nasal skeleton in position during the healing period.

RESUMEN

OBJECTIVES: To compare periodontal parameters of splinted posterior teeth versus control teeth over ten years of supportive periodontal therapy (SPT) and to assess the survival rate of splints. MATERIAL AND METHODS: Retrospective data of 372 SPT-patients was screened for splints (composite/fiberglass-reinforced composite) in the posterior (molars/premolars) which were inserted at least ten years before due to increased tooth mobility. For each splinted tooth (test), a corresponding control tooth had to be present at the first SPT-session after splint insertion (T1). Data was assessed at T1 and ten years later (T2). Possible influencing covariates for splint survival (mobility degree/Eichner class) were tested by Cox regression. The change in clinical attachment level (ΔCAL), probing pocket depth (ΔPPD) and the testing of possible influencing covariates was analyzed by using mixed linear regression. RESULTS: Twenty-four patients (32 splints, 58 splinted teeth) were included. Ten test and two control teeth were lost. No differences were observed between ΔCAL and ΔPPD of test teeth compared to control teeth (ΔCAL -0.38 ± 1.90 vs. 0.20 ± 1.27 mm; ΔPPD -0.17 ± 1.18 vs. 0.10 ± 1.05 mm). Twenty-two splints fractured during the observation period (survival-rate: 31%). Mobility degree and Eichner class did not influence time until fracture. CONCLUSIONS: Splinting of periodontally compromised and mobile posterior teeth does not have any disadvantage regarding the clinical periodontal situation when regular SPT is applied. However, splint fractures occur very often. CLINICAL RELEVANCE: Splinting of posterior teeth is a treatment option in addition to active periodontal therapy when patients are disturbed by tooth mobility but splints have a high susceptibility to fracture.

RESUMEN

Clinical indications for the newly released Ti-Zr (Roxolid®) alloy mini-implants (MDIs) aimed for overdenture (OD) retention in subjects with narrow alveolar ridges are not fully defined. The aim of this study was to analyze peri-implant and posterior edentulous area microstrains utilizing models of the mandible mimicking a "real" mouth situation with two (splinted with a bar or as single units) or four unsplinted Ti-Zr MDIs. The models were virtually designed from a cone beam computed tomography (CBCT) scan of a convenient patient and printed. The artificial mucosa was two millimeters thick. After MDI insertion, the strain gauges were bonded on the oral and vestibular peri-implant sites, and on distal edentulous areas under a denture. After attaching the ODs to MDIs, the ODs were loaded using a metal plate positioned on the first artificial molars (posterior loadings) bilaterally and unilaterally with 50, 100, and 150 N forces, respectively. During anterior loadings, the plate was positioned on the denture's incisors and loaded with 50 and 100 N forces. Each loading was repeated 15 times. The means with standard deviations, and the significance of the differences (two- and three-factor MANOVA) were calculated. Variations in the MDI number, location, and splinting status elicited different microstrains. Higher loading forces elicited higher microstrains. Unilateral loadings elicited higher microstrains than bilateral and anterior loadings, especially on the loading side. Peri-implant microstrains were lower in the four-MDI single-unit model than in both two-MDI models (unsplinted and splinted). Posterior implants showed higher peri-implant microstrains than anterior in the four-MDI model. The splinting of the two-MDI did not have a significant effect on peri-implant microstrains but elicited lower microstrains in the posterior edentulous area. The strains did not exceed the bone reparatory mechanisms, although precaution and additional study should be addressed when two Ti-Zr MDIs support mandibular ODs.

RESUMEN

BACKGROUND: Without surgical repair, flexor tendon injuries do not heal and patients' ability to bend fingers and grip objects is impaired. However, flexor tendon repair surgery also requires optimal rehabilitation. There are currently three custom-made splints used in the rehabilitation of zone I/II flexor tendon repairs, each with different assumed harm/benefit profiles: the dorsal forearm and hand-based splint (long), the Manchester short splint (short), and the relative motion flexion splint (mini). There is, however, no robust evidence as to which splint, if any, is most clinical or cost effective. The Flexor Injury Rehabilitation Splint Trial (FIRST) was designed to address this evidence gap. METHODS: FIRST is a parallel group, superiority, analyst-blind, multi-centre, individual participant-randomised controlled trial. Participants will be assigned 1:1:1 to receive either the long, short, or mini splint. We aim to recruit 429 participants undergoing rehabilitation following zone I/II flexor tendon repair surgery. Potential participants will initially be identified prior to surgery, in NHS hand clinics across the UK, and consented and randomised at their splint fitting appointment post-surgery. The primary outcome will be the mean post-randomisation score on the patient-reported wrist and hand evaluation measure (PRWHE), assessed at 6, 12, 26, and 52 weeks post randomisation. Secondary outcome measures include blinded grip strength and active range of movement (AROM) assessments, adverse events, adherence to the splinting protocol (measured via temperature sensors inserted into the splints), quality of life assessment, and further patient-reported outcomes. An economic evaluation will assess the cost-effectiveness of each splint, and a qualitative sub-study will evaluate participants' preferences for, and experiences of wearing, the splints. Furthermore, a mediation analysis will determine the relationship between patient preferences, splint adherence, and splint effectiveness. DISCUSSION: FIRST will compare the three splints with respect to clinical efficacy, complications, quality of life and cost-effectiveness. FIRST is a pragmatic trial which will recruit from 26 NHS sites to allow findings to be generalisable to current clinical practice in the UK. It will also provide significant insights into patient experiences of splint wear and how adherence to splinting may impact outcomes. TRIAL REGISTRATION: ISRCTN: 10236011.

RESUMEN

Maxillofacial fractures in the pediatric population are generally managed by conservative approaches such as soft diet and medication or semi-invasive procedures namely inter-maxillary fixation or circum-mandibular wiring. These approaches are preferred over any invasive treatment to minimize injury to the growing skeleton and tooth germs. Displaced fractures that cause functional problems such as restricted mouth opening, malocclusion or impaired breathing, mandate open reduction and internal fixation. However, surgical management is associated with morbidity related to general anesthesia, risk of injury to vital structures, and potential, skeletal or dental growth disturbances. This case report describes a non-invasive method of managing displaced, multiple fractures of the mandible in a pediatric patient, with the use of low intensity pulsed ultrasound to achieve favorable clinical outcomes and nil complications. Neither immobilization of the mandible with inter-maxillary fixation nor open reduction and internal fixation was used. Low intensity pulsed ultrasound therapy is painless and patient-friendly.

RESUMEN

BACKGROUND: There is a controversy on the effectiveness of post-operating splinting in patients with carpal tunnel release (CTR) surgery. This study aimed to systematically evaluate various outcomes regarding the effectiveness of post-operating splinting in CTR surgery. METHODS: Multiple databases, including PubMed, EMBASE, CINAHL, Web of Science, and Cochrane, were searched for terms related to carpal tunnel syndrome. A total of eight studies involving 596 patients were included in this meta-analysis. The quality of studies was evaluated, and their risk of bias was calculated using the methodological index for non-randomized studies (MINORS) and Cochrane's collaboration tool for assessing the risk of bias in randomized controlled trials. Data including the visual analogue scale (VAS), pinch strength, grip strength, two-point discrimination, symptom severity score (SSS), and functional status scale (FSS) were extracted. RESULTS: Our analysis showed no significant differences between the splinted and non-splinted groups based on the VAS, SSS, FSS, grip strength, pinch strength, and two-point discrimination. The calculated values of the standardized mean difference (SMD) or the weighted mean difference (WMD) and a 95% confidence interval (CI) for different variables were as follows: VAS [SMD = 0.004, 95% CI (-0.214, 0.222)], pinch strength [WMD = 1.061, 95% CI (-0.559, 2.681)], grip strength [SMD = 0.178, 95% CI (-0.014, 0.369)], SSS [WMD = 0.026, 95% CI (- 0.191, 0.242)], FSS [SMD = 0.089, 95% CI (-0.092, 0.269)], and the two-point discrimination [SMD = 0.557, 95% CI (-0.140, 1.253)]. CONCLUSIONS: Our findings revealed no statistically significant differences between the splinted and non-splinted groups in terms of the VAS, SSS, FSS, grip strength, pinch strength, and two-point discrimination. These results indicate that there is no substantial evidence supporting a significant advantage of post-operative splinting after CTR.

RESUMEN

The current study evaluated the stress distribution in a maxillary central incisor with mid-root fracture after splinting with different intra-radicular posts using 3D-finite element analysis (FEA). Five 3D-FEA models were constructed. Model 1 was an intact tooth with no fracture, Model 2: A tooth with a horizontal mid-root fracture, with no treatment. Model 3: Same as model 2, and intraradicular splinting using fiber post. Model 4: Same as model 2 and intra-radicular splinting using Protaper Gold file F3. Model 5: Same as model 2, and with intraradicular splinting with Ribbond. The FEA of all models was done to obtain the maximum Von-Mises stress in the root canal space, the dentin, the periodontal ligament, and the bone. The highest Von Mises stresses for the root canal space and the dentin were found in Model 3, followed by models 4, 5, and 2, and least in Model 1. The Von Mises stress of the periodontal ligament was the least in model 1. The Von Mises stress of bone was higher in all experimental models than in the baseline model. The results suggest that in cases where intra-radicular splinting is indicated, fiber posts and Ribbond are better alternatives to endodontic files due to the lower stresses exerted.

RESUMEN

BACKGROUND: Palmar burn injuries are common in young children and can result in contracture. METHODS: A prospective longitudinal study describes outcomes of palm and digit extension splint use following burn in 75 children (83 hands) aged < 5 years and determines whether specific cutaneous functional units (CFUs) are associated with early signs of contracture (ESC). Outcomes were assessed up to 9-18 months following burn. Routine clinical data was collected at therapy reviews. RESULTS: Children were splinted > 12 h/day for a mean of 158 days following burn. The mean time to splint cessation was 264 days following burn. Fourteen hands developed ESC (17%): 12 hands had full ROM restored following conservative management, 2 hands (3%) progressed to contracture. Hands that developed ESC had greater healing time (p = 0.002), greater number of CFUs affected (p < 0.001), and greater number of immediate first webspace and extended first webspace CFUs affected (p = 0.002, p < 0.001 respectively). ESC risk increases for each day to heal (odds ratio [OR] 1.1, 95% CI 1.0-1.2) and each CFU in extended first webspace (OR 2.8, 95% CI 1.5-5.0). CONCLUSION: Early and intensive splinting following palmar burn results in excellent ROM. Burns involving more CFUs or the first webspace are associated with ESC.

RESUMEN

BACKGROUND/AIMS: The recommendations for splinting are well established for the injuries of permanent dentition; however, ambiguity still exists for the injuries in primary dentition. Hence, this study aimed to determine the most appropriate dimensions of stainless steel wire and its extent, for achieving the physiologic mobility in primary dentition. MATERIAL AND METHODS: This study was designed as an in vitro experiment by using a typodont model of primary dentition. The baseline mobility of primary maxillary incisors was calibrated to the physiologic mobility of natural primary incisors by using a Teflon tape wrapped around the roots of resin teeth. Splinting was done using a stainless steel wire of 0.2 mm (Group I), 0.3 mm (Group II), and 0.4 mm (Group III). These groups were subdivided (a, b, and c) on the basis of the extent of the splint, and pre splint mobility (Pre-PV) and post-splint mobility (Post-PV) were tested by Periotest M. The splint effect was calculated by subtracting Post-PVs and Pre-PVs. RESULTS: The normal values of mobility in healthy human volunteers ranged from 10.5 to 13. The overall splint effect was higher in Group III irrespective of the extent of the splint, whereas it was found to be the lowest in Group I (b and c). The splint effect increased with the extent of the splint in all the groups. Among all the groups, the splint effect on the anchor teeth was observed to increase with the extent of the splint and the diameter of the wire. CONCLUSION: The mobility of the injured and anchor teeth splinted with 0.2-mm stainless steel wire was similar to the pre-splint and physiologic mobility. The most favorable extension was one tooth adjacent to the injured tooth on each side for both 0.2- and 0.3-mm wires.

RESUMEN

BACKGROUND: Parents may experience challenges implementing their child's therapeutic treatment following burn. METHODS: A mixed methods study was conducted to explore the parent experience of intensive splinting following palmar burns in young children (median age 16 months [IQR 14]). Thirteen parents were interviewed after cessation of their child's splinting (mean 12 months [SD 2] following burn). Parent interviews were semi-structured with open-ended questions and conducted one-to-one. Inductive thematic analysis was completed by two researchers with consensus achieved through discussion and agreement from third researcher. Themes were triangulated with quantitative data, including range of motion (ROM), scar, developmental and quality of life outcomes. RESULTS: Children used the splint intensively (>12-24 h/day) for median 179 days (IQR 74) with all splinting ceased by median 275 days (IQR 105). All children had full ROM at scar maturation. Thematic analysis revealed two main themes: parents perceive the impact of splinting to be greater on them than their child and parents perceive outcomes to be more important than burden. Parents described the importance of routine and therapeutic relationships in ongoing engagement with intervention. CONCLUSION: Parents consider intensive splinting to impact them more than their child with burden of care manageable considering overall outcomes.

RESUMEN

First aid intervention and pre-hospital (FAPH) practices are common in patients suffering from snakebite envenomation (SBE). In this study, we have reviewed the literature concerning the use of these practices in various regions of the world in the period 1947-2023 based on published prospective studies. A total of 71 publications fulfilled the inclusion criteria. In terms of the total number of patients in all studies that used each FAPH intervention, the most common practice was the application of tourniquets (45.8%). Other FAPH practices described include cuts/incisions (6.7%), the application of a variety of natural or synthetic substances at the bite site (5.6%), and ingestion of natural, usually herbal, remedies (2.9%). Washing the site of the bite was described in 9.1% of patients. There were other less frequent FAPH practices, including suction, splinting-immobilization, pressure-bandage, ice packs, application of a snake/black stone, and administration of alcoholic beverages. There were differences in the extent of application of FAPH interventions in different continents. Tourniquets were highest (55.7%) in Asia. Topical application of various products was common in South America, while pressure-bandage was only reported in Australia. We did not find any statistically significant variations in the frequency of the most frequent FAPH interventions at three-time intervals (before 2006, between 2006 and 2015, and after 2015). Our findings highlight the use of FAPH interventions in patients suffering SBE, some of which are known to be harmful. It is necessary to study these practices to a higher level of geographic granularity, using community-based surveys. Programs tailored to local contexts should be promoted, aimed at avoiding the use of harmful FAPH practices. It is also necessary to assess the efficacy and safety of some interventions through robust preclinical and clinical studies.

RESUMEN

The origins of contemporary orthopedics can be traced all the way back to antiquity. Despite the absence of modern imaging techniques, a few bright minds were able to lay the groundwork for understanding these fractures. This historical review will cover the process behind the various treatments for elbow fractures, such as splinting and casting, mobilization, amputation, fracture fixation, arthroplasty, and arthroscopy.

RESUMEN

Traumatic dental injuries (TDIs) are a relatively frequent occurrence, with roughly a third of adults experiencing a dental trauma at some time in their life.1 TDIs may present to dental professionals working within primary or secondary care settings. Patients presenting at the time of acute injury will require immediate management and careful long term follow up. Patients may also present later reporting a history of TDI, with developing complications and onward management required. To support dental care professionals, the International Association of Dental Traumatology's (IADT) Guidelines are available globally as a standardised tool to aid the assessment, management and follow up of dental trauma. These easy to access guidelines were updated in 2020 with four distinct publications:General Introduction,1 Fractures and Luxations,2 Avulsion of Permanent Teeth,3 and Injuries in the Primary Dentition.4 The current guidelines represent the best evidence based on available literature and expert opinion.1This paper aims to support dental professionals by specifically highlighting and describing updates in guidance, using the 2020 IADT published guidelines. By incorporating the 2020 guidelines into our everyday practice we aim to provide the most appropriate, standardised care, based on the highest level of available evidence to our patients.The full published guidelines are available free online via the IADT website.

RESUMEN

Avulsion injuries, though relatively uncommon, are one of the most serious of dentoalveolar injuries. Replantation at the scene of the incident is almost always the treatment of choice whenever possible. This paper outlines a step-by-step approach for the management of avulsion injuries, including a splinting protocol. This aims to support general dental practitioners in feeling more confident with managing these injuries.

RESUMEN

BACKGROUND: This study aimed to determine the relative positioning accuracy of multiple implants utilizing four distinct types of splinting materials. METHODS: The purpose of this in-vitro study was to compare the precision of four splinting materials in an open tray impression technique in multiple implant situations. Based on the material used for splinting, four groups were made (n = 40)- Group A: Conventional Method, Group B: Prefabricated Pattern Resin Framework, Group C: Prefabricated Metal Framework, Group D: Light Cured Pattern Resin, these groups were compared with the master model. A heat-cured clear acrylic resin and a master model were constructed. A pilot milling machine drill was used to drill four parallel holes in the anterior and premolar regions, which were later labeled as A, B, C, and D positions from right to left. Then, sequential drilling was carried out, and four 3.75­mm diameter and 13-mm long ADIN implant analogs with internal hex were placed in the acrylic model using a surveyor for proper orientation. The impression posts were then manually screwed to the implant analogs using an open tray, and they were secured to the implants using 10 mm flat head guide pins with a 15 N.cm torque. 10 Open tray polyether impressions were made, and casts were poured. Each splinting method's distortion values were measured using a coordinate measuring machine capable of recordings in the X-, Y-, and Z-axes. Comparison of mean distances for X1, X2, and X3 was made using the Kruskal-Wallis test, and Pairwise comparison was done using Post Hoc Tukey's Test. RESULTS: The differences between the groups were significant when assessing the distances X1, X2, and X3 (p < 0.05). The comparison of deviations between the groups revealed a statistically significant difference (p < 0.05) for the deviation distance X3 but not for the deviation distances X1 and X2. For distance Y1, the difference between the groups was statistically significant (p0.05), but it was not significant for distances Y2 and Y3. A statistically significant difference was seen in the comparison between the groups (p < 0.05) for the deviation distances Y1, Y2, and Y3. The results were statistically significant for the distance Z1 comparisons, namely, control vs. Group A (p = 0.012), control vs. Group B (p = 0.049), control vs. Group C (p = 0.048), and control vs. Group D (p = 0.021), and for distance Z3 comparison for control vs. Group A (p = 0.033). The results were statistically insignificant for the distance Z2 comparisons (p > 0.05). CONCLUSIONS: All splinting materials produced master casts with measurements in close proximity to the reference model. However, prefabricated pattern resin bars splinting showed the highest accuracy among the studied techniques. The most recent splinting techniques using prefabricated metal framework and light-cure pattern resin showed similar accuracy.

RESUMEN

Radicular cysts are the most common cystic lesions that affect the jaws, which, though mostly asymptomatic, can be seen radiographically as an oval or pear-shaped unilocular radiolucency in the periapical region. Nonsurgical root canal procedures and periapical surgery followed by placement of bone substitute and bioceramic root-end filling material is generally the treatment of choice. This case report highlights the endosurgical management of long-standing trauma that led to a radicular cyst with respect to three maxillary anterior teeth in a young adult. The clinical and radiographic examination led to a provisional diagnosis of a radicular cyst, which was confirmed by biopsy. Non-surgical root canal treatment was performed with Mineral Trioxide Aggregate (MTA) as the apical barrier and surgical enucleation of the cyst was performed followed by placement of hydroxyapatite bone graft.
