Abstract

Purpose: To evaluate the implant survival and the prevalence of biologic and mechanical complications in edentulous patients restored with complete-arch implant-supported fixed dental prostheses (IFDPs). Materials and Methods: Patients restored with complete-arch screw-retained IFDPs between January 2012 and December 2019 with a minimum 2-year follow-up were included. Outcome measures were cumulative survival rate (CSR) for implants and prostheses, biologic complications, and mechanical complications. A generalized estimating equation model was used to estimate potential risk factors for mechanical complications. Patient satisfaction was investigated using a standardized questionnaire. Results: A total of 44 prostheses supported by 268 implants in 30 patients were included for a mean duration of 4.8 years (range: 2 to 9 years). Eighteen of the prostheses were zirconia-ceramic (group ZC), and 26 were titanium-ceramic (group TC). The CSR for the implants and IFDPs was 99.3% (95% CI: 98.2% to 100.3%) and 92.5% (95% CI: 84.2% to 100.8%), respectively. The most common biologic complication was peri-implant mucositis (4.5%), followed by peri-implantitis (3.0%). The most common mechanical complication was ceramic chipping (45.5%), followed by crown debonding (13.6%) and framework fracture (4.5%). There was no significant difference in the prevalence of complications between groups TC and ZC (P > .050). The presence of cantilever (OR = 5.54, P = .048) and maxillary arch (OR = 5.94, P = .041) were significantly associated with mechanical complications. Patient satisfaction scores were generally high, but some continued to be bothered by speech problems (13.6%). Conclusion: Complete-arch IFDPs presented reliable clinical outcomes for edentulous patients with a high implant survival rate and a high level of patient satisfaction. However, a high incidence of mechanical complications occurred in the long term.

全弓种植体支持固定义齿的种植体存活率和并发症发生率:一项平均随访5年的回顾性研究。
目的:评价全弓种植体固定义齿修复无牙患者的种植体存活率及生物和机械并发症的发生率。材料和方法:纳入2012年1月至2019年12月期间采用全弓螺钉保留ifdp修复的患者,随访至少2年。结果测量是种植体和假体的累积存活率(CSR)、生物并发症和机械并发症。采用广义估计方程模型估计机械并发症的潜在危险因素。采用标准化问卷调查患者满意度。结果:30例患者共纳入44个假体,268个种植体支撑,平均持续时间4.8年(范围:2 ~ 9年)。其中氧化锆陶瓷18例(ZC组),钛陶瓷26例(TC组)。种植体和ifdp的CSR分别为99.3% (95% CI: 98.2% ~ 100.3%)和92.5% (95% CI: 84.2% ~ 100.8%)。最常见的生物并发症是种植体周围粘膜炎(4.5%),其次是种植体周围炎(3.0%)。最常见的机械并发症是陶瓷碎裂(45.5%),其次是冠脱落(13.6%)和框架断裂(4.5%)。TC组与ZC组并发症发生率比较,差异无统计学意义(P > 0.05)。悬臂(OR = 5.54, P = 0.048)和上颌弓(OR = 5.94, P = 0.041)的存在与机械并发症显著相关。患者满意度得分普遍较高,但仍有一些患者存在言语问题(13.6%)。结论:全弓IFDPs具有较高的种植成活率和较高的患者满意度,临床效果可靠。然而,长期发生机械并发症的发生率很高。

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.
