Moreover, evaluations of M3 position using panoramic radiography have shown insufficient accuracy. This study investigated the relationship between condylar fracture patterns and M3 position using panoramic radiography and computed tomography.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>This retrospective study included 280 patients with unilateral mandibular condylar fractures and ipsilateral M3 admitted to West China Hospital of Stomatology between January 2016 and June 2022. Patient medical records, panoramic radiographs, and computed tomography images were collected. The vertical and horizontal positions of M3 were classified using the Pell and Gregory system. M3 angulation was defined as the angle between the long axis of M3 and the mandibular occlusal plane. Condylar fracture patterns were classified as intracapsular (Types A\u2013C) or extracapsular (neck and base). Data were analyzed using McNemar\u2013Bowker test, Pearson chi\u2010squared test, and Fisher's exact test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Classification of M3 position differed significantly between panoramic radiography and computed tomography images (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05). There was a significant association between the mandibular condylar fracture pattern and M3 horizontal position on computed tomography (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05). Class I M3 position on computed tomography was associated with a higher incidence of intracapsular than extracapsular fractures, along with a higher incidence of Type B than base fractures; the opposite relationships were observed for Class II. No such association was identified on panoramic radiography.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Mandibular condylar fracture patterns were presumably influenced by M3 horizontal position on computed tomography.
