Abstract

Purpose: To evaluate the survival and complication rates of narrow-diameter implants (NDIs) for treatment with fixed restorations in premolar and molar sites.

Methods: A systematic review and meta-analysis were conducted following the preferred reporting items of systematic reviews and meta-analyses (PRISMA) guidelines. Searches were performed according to a Population-Intervention-Outcome (PIO) format in MEDLINE, Scopus, and Cochrane Library, supplemented by manual cross-referencing. Inclusion criteria encompassed clinical studies on NDIs (<3.75 mm diameter) restored with fixed dental prostheses (FDP) in the posterior region. Random-effect models were employed to pool survival and complication rates, and heterogeneity was assessed using the Q test and I2 statistic. Subgroup analyses explored variations by jaw location, implant material, and follow-up. The risk of bias was evaluated using the Cochrane tool for randomized controlled trials (RCTs) and the MINORS tool for non-randomized studies.

Results: Thirty-six trials involving 2741 NDIs were included in the systematic review and 29 in the meta-analysis. Survival rates (SRs) ranged from 92.73% to 100% with follow-up periods from 10.8 months to 12 years. Pooled SRs for maxillary (97.0%; 95%CI: 96.2%-97.8%) and mandibular (96.5%; 95%CI: 95.7%-97.3%) NDIs were not significantly different (p = 0.688). Comparing NDIs in the premolar and molar sites, jaw location demonstrated similar SRs of 97.5% (95% CI: 95.9%-99.1%) and 98.6% (95% CI: 96.5%-99.6%), respectively. Technical complication rates varied from 0% to 23.5%, with follow-up periods ranging from 1 to 12 years. These complications primarily included screw loosening, fractures, and detachment of restorations. Data on biological complications were notably limited, and due to the heterogeneity in reporting, comparisons were not feasible.

Conclusion: NDIs demonstrate high survival and low complication rates for therapy of the partially edentulous patient with FDPs in posterior sites. The clinical performance is consistent across jaw location and implant materials.

窄径种植体治疗后牙区固定修复:一项系统回顾和荟萃分析。
目的:评价窄径种植体(NDIs)在前磨牙和磨牙部位固定修复中的存活率和并发症发生率。方法:按照系统评价和荟萃分析(PRISMA)指南的首选报告项目进行系统评价和荟萃分析。根据MEDLINE、Scopus和Cochrane图书馆中的人群-干预-结果(Population-Intervention-Outcome, PIO)格式进行检索,并辅以人工交叉参考。纳入标准包括NDIs的临床研究(2统计)。亚组分析探讨了颌骨位置、种植体材料和随访的变化。使用随机对照试验(rct)的Cochrane工具和非随机研究的未成年人工具评估偏倚风险。结果:系统评价纳入了36项试验,涉及2741项ndi,荟萃分析纳入了29项。生存率(SRs)为92.73% ~ 100%,随访时间为10.8个月~ 12年。上颌合并SRs (97.0%;95%CI: 96.2%-97.8%)和下颌(96.5%;95%CI: 95.7% ~ 97.3%) ndi差异无统计学意义(p = 0.688)。比较前磨牙和磨牙位置的ndi,下颌位置的SRs相似,分别为97.5% (95% CI: 95.9%-99.1%)和98.6% (95% CI: 96.5%-99.6%)。技术并发症发生率从0%到23.5%不等,随访时间从1年到12年不等。这些并发症主要包括螺钉松动、骨折和修复体脱离。生物学并发症的数据明显有限,而且由于报告的异质性,比较是不可行的。结论:ndi治疗部分无牙后牙区fdp患者生存率高,并发症发生率低。临床表现是一致的跨颌位置和种植材料。

期刊介绍: The Journal of Prosthodontics promotes the advanced study and practice of prosthodontics, implant, esthetic, and reconstructive dentistry. It is the official journal of the American College of Prosthodontists, the American Dental Association-recognized voice of the Specialty of Prosthodontics. The journal publishes evidence-based original scientific articles presenting information that is relevant and useful to prosthodontists. Additionally, it publishes reports of innovative techniques, new instructional methodologies, and instructive clinical reports with an interdisciplinary flair. The journal is particularly focused on promoting the study and use of cutting-edge technology and positioning prosthodontists as the early-adopters of new technology in the dental community.
