Three-dimensional morphometry of mandibular condylar process fractures has moved beyond being merely a more vivid form of visualization. Contemporary CT and CBCT studies show that quantitative assessment of spatial displacement, rotation, ramus height loss, proximal fragment volume, and final fragment position already influences the clinical choice between conservative management and open reduction, as well as the choice of surgical access and fixation strategy. Adult practice is gradually shifting from two-dimensional signs and broad fracture classifications toward morphology-driven decision-making, in which the spatial geometry of the fracture determines both the likelihood of functional adaptation and the technical feasibility of stable osteosynthesis. The 3D variables most consistently linked to treatment are proximal fragment displacement, rotation, ramus height loss, and lateral translation, whereas fixation planning depends especially on fragment size, screw corridor feasibility, and fracture-line position relative to optimal plate placement. Although the available evidence does not yet support one universal numerical algorithm, it already provides practical guidance for selecting adult patients for ORIF, for digital preoperative planning, and for individualized fixation. Three-dimensional morphometry should therefore be regarded not as an optional supplement to diagnosis, but as a working instrument in the modern management of mandibular condylar process fractures.
