目标

对现代氧化锆植入物的长期研究仍然不足。这项为期 8 年的前瞻性随访研究调查了一体式氧化锆植入物。

材料和方法

本研究纳入了接受一体式氧化锆牙种植体（PURE 陶瓷种植体，Institut Straumann GmbH，巴塞尔，瑞士）的患者。除了种植体存活率和成功率之外，还评估了放射学和临床种植体参数。

结果

39 名患者的 67 个氧化锆种植体的总体存活率为 100%。总体成功率为89.6%。即刻氧化锆种植体的成功率为 94.7%，延迟种植体的成功率为 87.5%。与延迟种植体相比，即刻种植体显示出明显更高的骨嵴 ( p = 0.0120)。根据粉红色美学评分，8 年随访后，与延迟种植相比，即刻种植显示出更有利的美学效果 ( p = 0.0002)。

结论

8年后，一体式氧化锆种植体的成功率高达89.6%。关于植入时机，在个别情况下，立即植入比延迟植入稍有优势。

临床相关性

氧化锆种植体也可以考虑即刻种植，原则上不应排除。

Evaluation of one-piece zirconia dental implants: An 8-year follow-up study

Objectives

Long-term studies of modern zirconia implants are still insufficient. This prospective 8-year follow-up study investigated one-piece zirconia implants.

Materials and methods

Patients who had received a one-piece zirconia dental implant (PURE ceramic implant, Institut Straumann GmbH, Basel, Switzerland) were included in this study. Next to the implant survival and success rates, the radiographic and clinical implant parameters were assessed.

Results

The overall survival rate of 67 zirconia implants in 39 patients was 100%. The overall success rate was 89.6%. Around the immediate zirconia implants, the success rate was 94.7%, and around the delayed implants, 87.5%. The immediate implants showed a significantly higher bone crest compared to the delayed implants (p = 0.0120). According to the pink esthetic score, the immediate implants revealed more favorable esthetic results compared to the delayed implants after an 8-year follow-up (p = 0.0002).

Conclusions

After 8 years, the one-piece zirconia implants presented an 89.6% success rate. Regarding the timing of implantation, in individual cases, immediate implantation can have slight advantages over delayed implantation.
