Title: Morphological Influence of the Mandibular Third Molar Extraction to the Angulusmandibulae Using Cone-Beam Computed Tomography
Abstract: Objective: To explore the influence of the mandibular third molar extraction on the morphological changes of gonia angle.Methods: 30 adult orthodontic patients whose mandibular third molars need to be extracted for treatment had taken CBCT imaging before the teeth extracted,then 6 months later all the patients received the second CBCT scanning.We measured the width,height and length of the alveolar bone of the mandibular third molar through Mimics 10.01 software and compared the data using SPSS18.0 statisti-cal software.Results: After the extraction of the mandibular third molar,the width and height of alveolar bone located in the gonial angle reduced,and the difference had statistical significance,while the length had no conspicuous change.Conclusion: Extraction of mandibular third molar can reduce the width and height of angulusmandibulae bone to some extent,but the saggital length has no significant changes.
