Filter by:- Preoperative CT. - Virtual reduction of broken segments on software. - Gain occlusion. - Design surgical screw holes locating guide. - Design the custom-made plates. - Print the screw holes locating guide and the custom-made plate. under general anesthesia the parasymphseal fracture will be reduced using screw holes locating guide and the custom-made plates.
Objective To compare the efficacy of resorbable plates against titanium plates to determine the fixation stability in reducing mandibular fractures Method: Subjects will be recruited and divided into two groups by random allocation. Consents will be obtained and fracture sites will be examined clinically and radiographically. Control group will receive titanium plates and test group will receive resorbable plates. The patients will be recalled immediately at first postop day then at the end of the first month , second month and the third month.They will be evaluated for the reduction of the fractures.
the study intends to observe the outcome of interventions (concentrated growth factor with autograft and xenograft) used to expedite bone healing and adaptation with minimal side effects. Three different modalities are being used to bridge the mandibular fracture defects (>5mm-<5cm). Those modalities include group A- autograft, group B-autograft with concentrated growth factor, and group C- xenograft with concentrated growth factor. the outcomes are measured in terms of acquired bone density (Hounsfield unit) that is obtained at the 4th and 6th month post-operatively via cone-beam computed tomography.
This study compared the surgical approach to the lower jaw fractures, an approach from the face and an approach from inside the mouth were used and compared for the outcomes.
The aim of the current study was to evaluate the accuracy of computer-guided mandibular fracture reduction versus the classical work flow
A randomized prospective clinical study to compare screw Retained Arch Bar and Conventional Erich's Arch Bar in Maxillomandibular Fixation
Patients sustaining fractures of the upper (maxilla) and/or lower (mandible) jaw may be candidates for the minimally invasive technology evaluated in this study. Patients will be offered standard care including steel jaw wires or the polymer-based "zip tie"-like devices to be studied. Written consent with a full explanation of traditional "jaw wiring" techniques versus this experimental approach will be obtained from the patient. As mandible and maxilla fractures are typically treated under general anesthesia in the operating room, the devices will be applied to the patient's dentition while under general anesthetic. An exception to this will be minimally displaced or easily reduced fractures that can be treated by applying these devices in clinic under topical or local anesthetic. (Of note, wire-based techniques have been used for decades in a clinic-based application for such minimally or easily-reduced fractures.) The devices will allow stabilizing forces to the dental occlusion, achieving a similar function to temporary steel wire techniques ("arch bars"). This will allow the surgeon/principal investigator to treat the fractures with standard techniques such as applying titanium plates applied to the bone with titanium screws (known as "open reduction with internal fixation") or with sustained immobilization for 1-6 weeks (known as "closed reduction"). Note the devices are approved for 3 weeks duration. If treatment requires more than 3 weeks of immobilization, the devices will be removed and new devices re-applied. The experimental devices will be used solely as a replacement for wire-based techniques to achieve an immobile, stable jaw. If for any reason the required forces needed for jaw fracture stabilization are deemed inadequate with the experimental devices, standard steel wire techniques will be employed.
This study will address medical devices manufactured by Biomet Microfixation (d.b.a. Zimmer Biomet) designed for fixation and stabilization of the facial and mandibular skeleton.
Age can be estimated in different ways by using skeletal age and dental age. Currently, bone age is determine thanks to the wrist x-rayed, and the dental age using variation in mineralization (Demirjian's score) on the dental panoramic (Mincer 1993). More recently, reviews indicate the Computed tomography (CT) scan of the medial clavicular epiphysics can contribute to improve the accuracy of individual's age estimation (Houpert, 2016). Furthermore, with the recent advances, the very low dose CT scan acquisitions can be perform with sufficient quality for the teeth analysis. The goal of this study is to validate the use of dental CT for Demirjdian's staging method.
Twenty-five patients with mandibular angle fracture were subjected to reduction and fixation through intra-oral open reduction and semi-rigid min plate fixation near the superior border of the mandible at Champy's osteosynthesis line. The linear inter-fragmentary gap was measured at the inferior border of the mandible after fixation of the fractured bony segments in the final aligned position immediately postoperative on a panoramic radiograph for the mesio-distal plane and a cone beam computed tomography for the bucco-lingual plane to assess any lingual splay. The healing process was clinically followed for 3 months postoperatively for any complications and/or patient complains
