ObjectiveThe aim of this study was to test the bone thickness and potential screw length for osteosynthesis of condylar base fractures (according to the Loukota classification) with an experimental titanium plate, placed in an ideal position against two types of conventional plates.Study DesignAfter exclusion of completely edentulous mandibles 28 dentate macerated mandibles available at the time of the study were included. Linear regression models (LM) 1 & 2 compared the sums of the two cranial bone thicknesses and the three caudal thicknesses between the three different plate designs and linear models 3 & 4 tested the bone thickness in the two most cranial screw axes.ResultsLinear models 1&2 revealed significantly higher potential screw lengths for the experimental oblique plate. Equally, linear models 3&4 showed significantly higher bone thickness for the novel oblique plate.ConclusionThe novel proposed oblique plate allows for favorable plate positioning in a biomechanically ideal location with sufficient amounts of local bone for stable plate fixation. When plates with 15° angulated screw holes are used, stable bicortical plate fixation can be achieved.
