Abstract: POURPOSE: To retrospectively analyze jaw bone quality in patients with dental implants in the People's Hospital of Inner Mongolia Autonomous Region from October 2015 to October 2017, in order to provide clinical reference for bone quality classification. METHODS: The age, sex, implant site, and surgical technique and bone quality classifications of 387 patients were recorded. The related data were statistically and retrospectively analyzed using Excel and SPSS 22.0 software package. RESULTS: Among 387 patients, the classification of bone mass was mainly Class Ⅱ and ClassⅢ. There was no Class IV bone. The site of implantation was mainly the posterior region. The proportion of missing teeth in the mandibular posterior region was the largest, and the proportion of Class Ⅲ bone in the maxillary posterior region was the highest. The proportion of Class Ⅱ bone in the lower anterior region was the highest. There were more female patients than male patients, and most patients were between the age of 20-60 years old, Class Ⅲ bone was mostly found in all the groups. The number of Class Ⅲ bones was the greatest among patients undergoing additional surgery. CONCLUSIONS: Different types of implant sites have different types of bone quality; age and gender may affect the bone quality of the jaws, and implants in areas with poor bone quality will lead to an increase in the proportion of additional operations. Different types of bone quality also have an impact on the failure rate of implantation.
