Trauma Type

Mandibular fractures are one of the most frequent occurrences in maxillofacial trauma. Age of the patient, presence of additional injuries, co-morbid diseases of the patient, trauma type, and localization of the fracture must be considered while choosing the treatment strategy. A 12-year-old female patient reported with the complaint of fallen teeth due to trauma three days back. Clinical and radiographic findings revealed symphysis fracture with left sided parasymphysis and subcondylar fracture along with avulsion of 11 and 21. Intermaxillary fixation was done with Erich arch bars and elastics for the management of mandibular fracture, and rehabilitation of edentulous space was done using the avulsed teeth as pontics which were bonded to the adjacent abutment teeth using fiber-reinforced composite.

ABSTRACT For patients who require removal of anterior teeth due to periodontal problems there are a multitude of treatment considerations. Using the natural tooth as a pontic offers the benefits of being the right size, shape and color. This paper describes the immediate replacement of an anterior tooth using a preimpregnated fiber-reinforced composite with the natural tooth as the pontic. The abutment teeth can be preserved with minimal or no preparation, thus keeping the technique reversible, and can be completed at the chair side thereby avoiding laboratory costs. It can be used as an interim measure or as a definitive prosthesis.

Purpose: Intermaxillary xation (IMF) is an essential principle in the management of mandibular fractures; but with the recent advent of open reduction and internal xation (ORIF), the use of IMF is almost limited to intraoperative procedure only. This study aims to investigate and compare the effectiveness of Erich arch bar & intermaxillary xation (IMF) screws for the management of mandibular fractures. Materials And Method: A randomized prospective study was conducted on 20 patients with mandibular fracture, who were randomly allotted to two groups. Group A patients received intermaxillary xation using Erich arch bar and group B patients received IMF screws. The parameters assessed were time taken for application and removal of appliance, stability of occlusion, glove perforation, and pre-and post-operative plaque accumulation. Results: The mean time for placement of the Erich arch bar was 43.10 minutes as compared to 18.60 minutes with intermaxillary xation screws. Better occlusal stability was shown with an arch bar over IMF screws, and was statistically signicant. More glove tears or penetrations occurred during application in group A than Group B (p<0.01). Also, The Plaque Index assessment on removal of appliance showed a statistically signicant difference between the two groups; higher in the arch bar group. Conclusion: This study indicates that with acceptable occlusal stability, IMF screws technique is an effective and favourable alternative to Erich arch bars for temporary intermaxillary xation in mandibular fractures.

Background: The mandible is one of the bones most affected by facial fractures commonly resulting from trauma to the face. The ultimate goal of treatment is to re-establish the pre-injury dental occlusion (bite), mandibular anatomy and jaw function of the patient. Treatment approaches range from conservative non-invasive management by ’closed’ reduction and immobilization using intermaxillary fixation (IMF) to the more invasive surgery-based ’open’ reduction incorporating an internal fixation approach. Purpose: The purpose of this case series was to describe the close reduction method as a form of treatment in cases of neglected mandibular fracture. Cases: Four cases of single or multiple mandibular fracture were presented. Case management: All of the cases were managed using a closed reduction method and IMF. Conclusion: A closed reduction method in this case series produced encouraging results and could be considered an alternative in the treatment of neglected mandibular fractures with displacement.

Background: Mandible is one of the commonly fractured bone due to trauma, assault and falls. Treatment includes closed and open methods. Methods of open reduction and internal fixation have changed and di­versified enormously in the past few years. Champy’s miniplate fixation, dynamic compression plating has become a standard approach. More recently, three dimensional miniplates have been developed by Farmand which may be effectively used in mandibular fractures. The aim of this study was to check the adequacy of three dimensional miniplate in man­agement of mandibular fracture occurring in the interforaminal region. Methods: A prospective clinical study was carried out in patients attend­ing Emergency Department and Department of Oral and Maxillofacial Surgery, Nobel Medical College and Teaching Hospital (NMCTH) suffer­ing from mandibular fractures in interforaminal region from May 2018 to January 2019. Results: A total of 17 patients with 18 fracture in interforaminal region, all male were included in the study. The age ranged from 16 to 50 years with a mean of 29.17 ± 9.48. Road traffic accident was the leading cause of injury with 15 out of 17 patients (88.23%). There was no incidence of wound infection, wound dehiscence, malunion, nonunion, plate fracture within the follow up period of 3 months. One fracture was unstable on 1st postoperative day and also had mildly deranged occlusion which was man­aged with intermaxillary fixation for two weeks. Conclusions: Three dimensional plates fulfills the treatment goals of ad­equate stabilization and fixation of mandibular interforaminal fractures.

Summary Background/Aim: Gunshot injury-related mandibular fractures often have a complex pattern, characterized by comminution, bone loss, and soft-tissue avulsion. The management is difficult and varies between individual cases. Case Report: A 41-year-old male patient presented with marked swelling and ecchymosis in the left mandibular region. Intraorally, he had a deviated open bite on the left side. A unilateral comminuted mandibular fracture was diagnosed by panoramic radiograph and computed tomography. An acrylic dental splint-guided open reduction and internal fixation, including intermaxillary fixation through brackets and intermaxillary elastics, was planned. No complications were observed throughout the healing period, and healing at the fracture site was satisfactory. The occlusion returned to the preinjury position and was stable. Conclusions: This case report shows that successful functional and esthetic results can be achieved with a strict patient-specific treatment protocol for a comminuted mandibular fracture due to gunshot injury.

Fibre Reinforced Composites

Aim: To describe a protocol to replace few missing anterior teeth with periodontally compromised abutments. Background: Due to their lower modulus of elasticity, fibre reinforced composites (FRCs) minimize the stress level at the tooth restoration interface and enable an adjustment of the framework’s mechanical properties by inserting adequate fibre volumes. Direct and semi-direct fabricated FRC Fixed Dental Prosthesis (FDP) now compete successfully with conventional cast metal resin-bonded FDPs. Case Description: A Fibre Reinforced Composite(FRC) bridge was given to replace missing 31 and 41. The FRC material was bonded from canine to canine (33-43) to ensure the stability of the periodontally compromised abutment teeth by acting as a splint with minimal intervention. Conclusion: Fiber-reinforced composite restorations reduce the number of appointments and make single visit dentistry possible especially when the abutments are periodontally compromised and require splinting. Clinical Significance: This case report demonstrates the benefits of splinting periodontally compromised abutment teeth.

Abstract This case report demonstrates a technique that is useful for precompressing mandibular fractures and obtaining anatomical reduction of the fracture edges without the use of peroperative intermaxillary fixation (IMF) in a mandibular fracture by using two modified reduction forceps. The first forcep is positioned at the inferior mandibular border and the other in the neutral zone where it is an ideal location to place a fixation plate in mandibular fractures. This technique is indicated for the anatomic reduction in mandibular fractures of the partial dentate patient. Citation Shinohara EH, Mitsuda ST, Miyagusko JM, Horikawa FK.

Reinforced Composite

Abstract Tires are fabricated using single ply fiber reinforced composite materials, which consist of a set of aligned stiff fibers of steel material embedded in a softer matrix of rubber material. The main goal is to develop a mathematical model to determine the local stress and strain fields for this isotropic fiber and matrix separated by a linearly graded transition zone. This model will then yield expressions for the internal stress and strain fields surrounding a single fiber. The fields will be obtained when radial, axial, and shear loads are applied. The composite is then homogenized to determine its effective mechanical properties—elastic moduli, Poisson ratios, and shear moduli. The model allows for analysis of how composites interact in order to design composites which gain full advantage of their properties.
