露龈笑患者上颌前牙区牙槽骨形态的研究
The study of upper anterior alveolar morphology in gummy smile patients
摘要
Abstract
Objective To investigate the anatomical features of alveolar bone in gummy smile patients with cone beam computed tomography ( CBCT) , and provide the reference for miniscrews implanted in anterior alveolar crest. Methods A total of 63 cases of adults with gummy smile were selected for the study and the CBCT data of jaw bones were obtained. The mesiodistal interradicular distances, buccal-lingual thickness and buccal cortical bone thickness were measured at three different level which included 4 mm, 6 mm and 8 mm above the alveolar crest. Results The mesiodistal interradic-ular distances increased along with distance between measure level and alveolar crest. ( P<0. 05) . The interradicular dis-tance were the least when measured between central incisor and lateral incisor ( P<0. 05) . The interradicular space be-tween central incisors presented the least buccal-lingual thickness ( P<0. 05) . No significant differences were observed between the other thicknesses of anterior interradicular spaces ( P>0. 05) . The buccal cortical bone thickness increased along with distance between measure level and alveolar crest ( P<0. 05) . The thicknesses were the least between central incisors while the most between lateral incisor and canine ( P<0. 05) . Conclusion The mesiodistal interradicular dis-tances, buccal-lingual thickness and buccal cortical bone thickness are found increased with the height level. Given the most bone mass and cortical bone thickness, canine and lateral incisor interval can be recommended as the place for the miniscrews inserting.关键词
