Development and biomechanical testing of a new osteosynthesis plate (TCP®) designed to stabilize mandibular condyle fractures

Evaluation of trapezoidal-shaped 3-D plates for internal fixation of mandibular subcondylar fractures in adults

“…A single L, Y plate, or 3-D plate has been used in the treatment of condylar fractures, 16 which confirm to the tensile stress pattern at the condylar neck region. Trapezoidal condylar plate (TCP) is such a 3-D plate shaped for adaptation in the anatomically constricted region of condylar neck.…”

“…Hence, this plate meets the criteria of 2 single miniplates with reduced hardware, leading to a less infection rate. 16 The aim of this study was to evaluate the efficacy of single trapezoidal 3-D miniplates in subcondylar fractures.…”

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

“…Moreover, their smaller size helps to avoid excessive soft tissue stripping during surgery and improves handling in minimally invasive surgical approaches. Actual clinical results have suggested that use of these 3D plates is superior to the previous two miniplates technique 4,7) . Furthermore, visual analyses of the macroscopic fracture line displacement and photoelastimetric analysis of the pre-and postsurgical strain patterns have been reported 4,6,7) .…”

Furthermore, visual analyses of the macroscopic fracture line displacement and photoelastimetric analysis of the pre-and postsurgical strain patterns have been reported 4,6,7) . According to Champy et al 8) , as a rule, internal rigid fixation has to be sufficiently stable in mandibular fracture ORIF to fulfill the principles of functionally stable osteosynthesis and thus induce sound bone healing.…”

“…Of these, 3D plates of various shapes, such as squares and rectangles, have been introduced for subcondylar fracture treatment and are regarded as the best mechanical components to ensure primary stabilization of condylar fractures by stabilizing the double buttresses of the anterior and posterior parts. Unlike in the two miniplates technique, these specially designed plates are even smaller and show greater osteosynthetic stability through the mechanical connection between the two plate arms 4,7) . Moreover, their smaller size helps to avoid excessive soft tissue stripping during surgery and improves handling in minimally invasive surgical approaches.…”
