摘要: 目的 研究不同骨质类型对中老年患者种植修复长期稳定的影响。方法 回顾性分析烟台市口腔医院种植科就诊,行后牙单冠种植修复的47例中老年(50~70岁)患者,功能性负荷5年后,通过平行投照根尖放射线片,测量比较不同骨质条件下种植体周边缘骨吸收、骨密度及骨小梁的变化情况。结果 种植修复体功能性负荷5年后,II-III类骨质组的种植体边缘骨吸收为近中(0.08±0.12)mm,远中(0.03±0.12)mm;IV类骨质组近中(0.01±0.12)mm,远中(-0.03±0.21)mm,差异无统计学显著性(P>0.05);II-III类骨质组和IV类骨质组的种植体周骨密度和骨小梁分形维数均无显著差异(P>0.05)。结论 不同骨质类型对中老年患者种植体周骨吸收、骨密度及骨小梁结构无显著影响。

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.
