“…According to previous literature, FEA has been a promising applicable tool in OMF surgery to analyse different types of fracture management and osteosynthesis implants [20][21][22][23][24]38]. We decided to evaluate the effectiveness, applicability, reproducibility, and reliability of FEA by using two different simulation software, namely: Solidworks and Comsol Multiphysics.…”

“…It would be attractive when three-dimensional (3D) modelling and nite element analysis (FEA) could replace model testing. FEA is a non-invasive computational method to evaluate the stress distribution and displacement within a structure on load application [20,21]. It is a reliable and accurate numerical simulation tool for studying force distribution in the OMF area [21,22].…”

Purpose To investigate the applicability of finite element analysis (FEA) in Oral and Maxillofacial (OMF) surgery, by studying the effect of mandibular body height and osteosynthesis positioning on unilateral mandibular body fractures based on Champy’s technique. This proof of principle is a step towards developing a validated FEA simulation method that may be useful in the clinical setting for optimising mandibular fracture management. Methods Mandibles made of polyurethane foam (Synbone®), with heights of 18, 14, and 10 mm were used to create a FEA model with a unilateral straight-line fracture, fixated with a standard commercially available 6-hole 2 mm titanium miniplate (KLS Martin Group). Two different FEA programs were used for the comparison, namely: Solidworks and Comsol Multiphysics. The FEA outcomes were compared with a series of mechanical tests with polymeric models fixed in a customised device and loaded onto a mechanical test bench. Results First, the study illustrated that the optimal plate position appeared to be the upper border. Second, lower mandibular height increases instability and requires a stronger osteosynthesis system. Conclusion The FEA’s and polymeric model testing outcomes of unilateral non-comminuted fractures were highly comparable with current opinions of mandibular fracture management. FEA is an applicable tool in OMF surgery, as it can be used to predict the treatment outcome of mandibular fractures. The promising outcome of this study makes it worthwhile to do more extensive analysis in order to determine whether FEA alone is sufficient for optimisation of fracture management.

“…1 The mandible angle has been reported in many studies to be one of the most common locations to be fractured. [1][2][3][4][5][6][7][8] Management of mandible fractures can be complex and/or complicated. Presentation may differ greatly pending the mechanism of injury such as assault versus gunshot wound resulting in a single fracture, significant comminution, or even bone loss.…”

Management of mandible angle fractures can be challenging within the confines of the oral cavity where the use of linear instruments may result in structural weakness or malalignment secondary to improper placement. A right angle drill can facilitate a more ergonomic approach, with direct perpendicular placement of the instrument over the angle fracture. In addition, local soft tissue strain is minimized, and the need for a transcutaneous exposure can be avoided for additional plate placement. The right angle drill technique is simple, reproducible, and can be easily incorporated into routine mandible angle fracture management.
