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： Edited by Steven E. Eckert, DDS, MS ISSN (Print): 0882-2786 ISSN (Online): 1942-4434 This highly regarded, often-cited journal integrates clinical and scientific data to improve methods and results of oral and maxillofacial implant therapy. It presents pioneering research, technology, clinical applications, reviews of the literature, seminal studies, emerging technology, position papers, and consensus studies, as well as the many clinical and therapeutic innovations that ensue as a result of these efforts. The editorial board is composed of recognized opinion leaders in their respective areas of expertise and reflects the international reach of the journal. Under their leadership, JOMI maintains its strong scientific integrity while expanding its influence within the field of implant dentistry. JOMI’s popular regular feature "Thematic Abstract Review" presents a review of abstracts of recently published articles on a specific topical area of interest each issue.
