This study aimed to evaluate the effect of aging on the changes in implant stability over time following implant placement.
A total of 104 patients in four age ranges (group 1: <60 years, group 2: 61-70 years, group 3: 71-80 years, and group 4: >80 years) were included. Bone-level tapered implants were placed without implementing any bone augmentation procedure. The final torque value displayed on the implant engine during implant insertion was recorded. Cone-beam computed tomography (CBCT) was performed immediately after surgery to analyze the bone quality around the implant. Implant stability was measured immediately after surgery and 2, 4, and 8 weeks after surgery.
In the CBCT image, higher grayscale values were observed in the order of group 1, group 2, and groups 3/4, with statistical significance (p < .05). There was no significant difference in the insertion torque values between age groups (p ≥ .05). Groups 1 and 2 showed lower implant stability values after 2 and 4 weeks compared to immediately and 8 weeks after surgery (p < .05); however, groups 3 and 4 showed no significant difference between the results measured at different timepoints (p ≥ .05).
Implant treatment in elderly patients is successful showing a settled implant stability over time following implant placement when the implant is appropriately engaged in the alveolar bone in the absence of bone augmentation.
本研究旨在评估年龄对种植体植入后随时间推移种植体稳定性变化的影响。
共纳入 104 名患者，分为 4 个年龄组（组 1：<60 岁，组 2：61-70 岁，组 3：71-80 岁，组 4：>80 岁）。所有患者均植入骨水平锥形种植体，不实施任何骨增量手术。记录种植体插入过程中种植机上显示的最终扭矩值。术后即刻行锥形束 CT（CBCT）检查，分析种植体周围骨质量。术后即刻、2 周、4 周和 8 周测量种植体稳定性。
在 CBCT 图像中，灰度值依次为组 1、组 2 和组 3/4 最高，差异具有统计学意义（p<.05）。不同年龄组间的插入扭矩值无显著差异（p≥.05）。组 1 和组 2 在术后 2 周和 4 周时的种植体稳定性值低于术后即刻和 8 周时（p<.05）；但组 3 和组 4 在不同时间点的测量结果之间无显著差异（p≥.05）。
在不进行骨增量的情况下，当种植体适当植入牙槽骨时，老年患者的种植体治疗是成功的，种植体植入后随时间推移种植体稳定性逐渐稳定。
