Abstract

Abstract: Objective: To evaluate the relationship between arch morphology, sagittal root position (SRP), and alveolar bone thickness of maxillary anterior teeth through cone-beam computed tomography (CBCT) images, and to group them according to age and gender. Methods: The CBCT images of 160 patients who met the inclusion criteria in Henan Province were analyzed and grouped according to dental arch morphology, age, and gender. Three hundred and twenty sagittal CBCT images of the maxillary central incisor of these patients were examined to measure the thickness of labial and palatal plates for statistical analysis. Results: The alveolar bone thickness was significantly depended on arch morphology and SRP. The bone thickness in the palatine side was the highest in the circular dental arch and grade I SRP. Apical arch type and grade II SRP type had the highest labial bone thickness. There was no correlation between dental arch morphology and SRP. Age, gender, arch shape, and SRP were significantly correlated with alveolar bone thickness. Conclusion: Age, gender, arch shape, and SRP were correlated with alveolar bone thickness of maxillary central incisor. Clinicians should consider these factors when planning implantation.

Key words: maxillary central incisor teeth, cone-beam CT, dental arch morphology, alveolar bone thickness, dental implantation
