Abstract

Purpose: Although immediate-loading implant (ILI) treatment is a general treatment strategy for fully edentulous maxillae, long-term evidence is required. The purpose of this study was to evaluate the long-term clinical results of, and risk factors for, ILI treatment in fully edentulous maxillae.

Materials and methods: ILI treatments of maxillae using 526 implants in 117 patients were reviewed retrospectively. The longest and mean observation periods were 15 years and 9.2 years, respectively. Kaplan-Meier survival curve analysis, log-rank tests, and multilevel mixed-effects parametric survival analysis were used for statistical analyses.

Results: Overall, 38 of 526 implants failed in 23 patients, and the estimated 15-year cumulative implant-level and patient-level survival rates were 90.7% and 73.7%, respectively. The cumulative implant survival rate was significantly higher in female patients than in male patients. Sex, implant length, and implant diameter were significantly associated with implant survival.

Conclusion: ILI treatment of completely edentulous maxillae demonstrated viable long-term clinical outcomes. Male sex, shorter implant length, and narrow implant diameter negatively affected implant survival. Int J Oral Maxillofac Implants 2023;38:516-522. doi: 10.11607/jomi.10310.

全无牙上颌即刻加载种植体的5- 15年生存率:一项回顾性队列研究的多水平分析

目的:虽然即刻加载种植体(ILI)治疗是全无牙上颌的一般治疗策略，但需要长期的证据。本研究的目的是评估全无牙上颌ILI治疗的长期临床结果和危险因素。材料与方法:回顾性分析117例上颌526颗种植体的ILI治疗方法。最长观测时间为15年，平均观测时间为9.2年。采用Kaplan-Meier生存曲线分析、log-rank检验和多水平混合效应参数生存分析进行统计分析。结果:总体而言，23例患者的526个种植体中有38个失败，估计15年累积种植体水平和患者水平的生存率分别为90.7%和73.7%。女性患者的累积种植体存活率明显高于男性患者。性别、种植体长度和种植体直径与种植体存活率显著相关。结论:ILI治疗上颌全无牙具有良好的远期临床效果。男性、较短的种植体长度和较窄的种植体直径对种植体存活率有负面影响。口腔颌面种植[J]; 2009;38(5):516-522。doi: 10.11607 / jomi.10310。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
