Anatomical morphology of the submandibular gland fossa by cone beam CT
摘要
Abstract
To investigate the anatomic morphology of the submandibular gland fossa in adults by cone beam computed tomography (CBCT) system in order to provide evidence for dental implantation in mandibular molar area. The CBCT images of 88 patients with missing mandibular molars were enrolled in this study. The depth of the subman-dibular gland fossa in the coronal plane of the missing teeth was measured by DCTViewer software. The result showed that the rate of the submandibular gland fossa in dental positions and the depth of the submandibular gland fossa were different. The data of the depth of the submandibular gland were subjected to normal distribution. There were about 59. 4％ (38/64) in the mandibular first molar area existed submandibular gland fossa and the mean depth was (1. 46 ±0. 69) mm. The presence of submandibular gland in mandibular second molar area was about 83. 3％ (30/36) and the mean depth was (1. 84 ± 0. 86) mm. There was no significant difference of different gender in the depth of submandibular gland fossa. The anatomical structure of the submandibular gland exhibits great variation. Clinicians should be fully aware of the importance when implanted in the mandibular posterior area.关键词
