A 3-dimensional finite-element analysis investigating the biomechanical behavior of the mandible and plate osteosynthesis in cases of fractures of the condylar process

Finite element analysis of newly introduced plates for mandibular condyle neck fracture treatment by open reduction and rigid fixation

“…18,19 Nowadays, the open reduction and rigid fixation (ORIF) in a plate numerical evaluation is possible thanks to them. Although few studies have used the finite element method, [20][21][22][23] the results of in vitro studies are similar in some ways to those found in computational studies, regarding the use of 2 stable titanium miniplates in such fractures. In addition, future clinical trials, applying the methodology with finite elements or not, are postulated to better indicate the most appropriate techniques for osteosynthesis in cases of mandibular condyle fractures.…”

Treatment of high fracture of the neck of the mandibular condylar process by rigid fixation performed by lag screws: Finite element analysis

“…9,24-27 Ideas for rigid internal fracture fixation in the condylar area (base, low neck, high neck, and head) have significantly changed in the last decade, [25][26][27][28][29] but the issue of optimal stabilization of the reduced fracture remains unclear because even classical fixations can have unknown biomechanical (mathematical) solutions, 30 and moreover some authors suggest that 3 lag screws with 2.0 mm diameters are impossible to insert in to a condyle fracture. 6 Thus, the topic of condylar fracture osteosynthesis remains highly controversial and challenging.…”

Unexpected Plate Fracture in a Three-Dimensional Subcondylar Locking Plate System

“…Wagner et al 5) demonstrated its biomechanical superiority experimentally in 2002. Additionally, in terms of immediate function without maxillomandibular fixation, this double miniplate fixation exceeded the functional force exerted on the condyle, enabling immediate functional loading, as reported in both a biomechanical model study and clinical trials 1,3,5,6) . Following these basic bony biological and biomechanical studies, specially anatomically designed 3D plates for subcondylar fracture ORIF were proposed and are now available for clinical use 1,4) .…”
