Cone beam computed tomography (CBCT) was used to measure and analyze the anatomy of the posterior maxilla.Method: Fifty patients who had completed CBCT scans of the posterior maxilla were selected. Three-dimensional reconstruction technology was used to analyze gingival vertical height, anterior-posterior width of the maxillary sinus, distance between the lateral wall of the maxillary sinus and the root of the tooth, and the thickness of the lateral wall of the maxillary sinus.Results: The results showed that the mean value of gingival vertical height was 3.5 ± 0.5 mm, the mean value of the anterior-posterior width of the maxillary sinus was 14.5 ± 1.3 mm, the mean value of the distance between the lateral wall of the maxillary sinus and the root of the tooth was 9.5 ± 精品文档---下载后可任意编辑1.1 mm, and the mean value of the thickness of the lateral wall of the maxillary sinus was 2.5 ± 0.6 mm.Conclusion: CBCT technology can provide reliable anatomical data, effectively reducing surgical risks and increasing the success rate of dental implant surgery in the posterior maxilla.【Keywords】 CBCT, posterior maxilla, dental implant, anatomical data, surgical risk
