Abstract

Abstract: The mandibular central incisor as orthodontic guidance often moves in a large scale, and the thickness of alveolar bone in this area is relatively thin, which is prone to dehiscence, fenestration, and other undesirable effects in the process of orthodontic treatment. Therefore, it has great clinical significance to fully understand measuring tools and influencing factors of alveolar bone thickness in the lower middle incisor area. At present, observation of the alveolar bone in the lower central incisor area is mainly conducted through cone beam computed tomography(CBCT), and its main influencing factors are vertical bone type, sagittal bone type, lower incisor inclination, age, gender and so on. Although numerous studies have been done in this field, a consensus on such issue has not be achieved. The purpose of this paper is to summarize the CBCT measurement of alveolar bone in the lower central incisor area and the influencing factors of its thickness before orthodontic treatment, in order to provide instruction for clinical practice.

Key words: lower incisor, alveolar bone thickness, cone beam computed tomography, facial type, mandibular incisor proclination
