Objective To evaluate various anatomic parameters of mandible and temporomandibular joint in Guangdong population. Methods A total of 265 patients admitted to Stomatology Hospital, Southern Medical University were selected to measure the condyle length , the condyle height, the height of mandibular ascending branch, and the position of the inferior mandibular nerve entering mandibular ascending branch in male and female respectively by using CBCT. Results In all patients, the mean length of the condyle was 19.2 mm in two-dimension and 20.3 mm in three-dimension, and the condyle length in males was showed longer than female by 3.6 mm. Mandibular height, condylar height, and the height of mandibular ascending branch was 59.6 mm, 22.8 mm, and 38.3 mm, respectively. Males showed longer than female in mandibular height by 6.4 mm, with statistical differences between in male and female. The width of mandible ascending branch, the distance from the uvula to the anterior ridge of the ascending ramus and the distance from the uvula to the posterior border of the ascending ramus were 29.4 mm, 14.8 mm, and 14.6 mm, respectively, with no statistical difference between male and female. Conclusions CBCT has more significant accuracy in the measurement of temporomandibular joint. The results of this experiment enrich the mandibular anatomical data of Chinese population and contribute in the development of artificial temporomandibular joint which is suitable for Guangdong population.
