Abstract

Abstract: Objective To evaluate the influence of alveolar bone density on the long-term stability of dental implants in middle-aged and elderly patients. Methods A retrospective study of 47 middle-aged and elderly (50~70 years old) patients who underwent posterior single-crown implant restoration in Yantai Stomatological Hospital was performed after 5 years of functional loading. The apical radiographs were used to measure and compare the changes of peri-implant marginal bone loss, bone density, and trabecular bone structure. Results The mesial and distal marginal bone loss in the type II-III bone group was（0.08±0.12）mm and（0.03±0.12）mm respectively, while（0.01±0.12）mm and（-0.03±0.21）mm in the type IV bone group. No statistical difference was found between the two groups（P>0.05）. Conclusion Alveolar bone density has no influence on marginal bone loss, bone density, and trabecular bone structure in the group of middle-aged and elderly patients.
