METHODS: This study included 28 patients with 38 FRC prostheses supported by 96 implants. Implant and prosthesis survival and success rates were evaluated using Kaplan-Meier analysis.
RESULTS: The 10-year implant survival and success rate, as determined by Kaplan-Meier analysis, was 96.9%, and the prosthesis survival and success rates were 94.7% and 92.0%, respectively. None of the parameters under investigation were significantly correlated with prosthetic survival or successful outcomes, but three parameters were correlated with higher peri-implant bone levels: implant placement in the mandible as opposed to the maxilla, shorter P-FDP spans, and natural teeth on the opposing arch.
CONCLUSIONS: FRC P-FDPs supported by short and extra-short implants presented high, up to 10-year, survival and success rates, when used to restore partially edentulous arches.
方法:本研究包括28名患者,38个FRC假体由96个植入物支持。使用Kaplan-Meier分析评估植入物和假体的存活率和成功率。
结果:植入物的10年生存率和成功率,根据Kaplan-Meier分析,为96.9%,假体存活率和成功率分别为94.7%和92.0%,分别。研究中的参数均与假体存活或成功结局无显著相关,但是三个参数与较高的种植体周围骨水平相关:种植体放置在下颌骨而不是上颌骨,较短的P-FDP跨度,和相对拱上的天然牙齿。
结论:FRCP-FDP由短和超短植入物支持,长达10年,生存率和成功率,当用于恢复部分无牙的拱门时。
