Osseointegration involves an osseous healing response that may be compromised by aging. This study aimed to test the hypothesis that there is no difference between older and younger adults in osseointegration success. A comparison was made between closely matched groups of 39 older adults who had 190 implants supporting 45 oral prostheses and 43 younger adults who had 184 implants supporting 45 oral prostheses. Patients were monitored for a period of 4 to 16 years after prosthetic loading. At the most recent follow-up, the cumulative implant success was 92.0% for the older group compared to 86.5% for the younger group. No statistical significance could be attributed to the difference in implant survival between the groups throughout the study period. Furthermore, the most common outcome for individual prosthetic sites was 100% implant success, and the original prosthetic design was maintained for as long as each patient was monitored in 41 or 45 prosthetic prescriptions for the older patients, and in 39 of 45 prescriptions for the younger patients.
骨结合涉及一种可能会因衰老而受损的骨愈合反应。本研究旨在验证一个假设，即老年人和年轻人在骨结合成功率方面没有差异。对两组匹配度高的人群进行了比较，一组是39名老年人，他们有190颗种植体支持45副口腔修复体；另一组是43名年轻人，他们有184颗种植体支持45副口腔修复体。在义齿加载后，对患者进行了4至16年的监测。在最近一次随访时，老年组种植体的累积成功率为92.0%，而年轻组为86.5%。在整个研究期间，两组之间种植体存活率的差异无统计学意义。此外，各个修复部位最常见的结果是种植体100%成功，并且在对老年患者的41或45份修复处方以及年轻患者的45份处方中的39份进行监测的时间内，每位患者都维持了原来的修复设计。
