Mini-dental implants (MDIs) have been used to support and retain overdentures, providing patients with a less invasive placement procedure. Although lucrative, the use of MDIs to retain a maxillary overdenture is still not an established treatment modality. This systematic review aims to answer the question: Do mini-implant-retained maxillary overdentures provide a satisfactory treatment outcome for complete edentulism?
A systematic search for relevant articles was conducted to include articles published until April 2021 in the following electronic databases: CINAHL, Cochrane, EMBASE, PubMed, and Web of Science. All empirical studies evaluating the biological, survival, or patient-reported outcomes after placing mini-implant-retained overdentures in maxilla were considered for inclusion. The risk of bias was assessed by utilizing the Joanna Briggs Institute critical appraisal checklist. Study screening and data extraction were conducted by three reviewers independently.
The electronic search retrieved 1276 titles after omitting duplicates. Twenty articles were considered for full-text review, of which six studies were included in this systematic review. The included studies evaluated a total of 173 participants with a mean age of 66.3 years. The overall mini-implant survival rate was 77.1% (95% CI: 64.7-89.5%) with a mean follow-up time of 1.79 years (range: 6 months to 3 years). Implant survival differed significantly when comparing complete and partial palatal coverage overdentures. Those with complete palatal coverage exhibited less bone loss overall compared to partial coverage overdentures. Participants of all studies reported an increase in the quality of life and in satisfaction after rehabilitation treatment with MDIs.
The survival rate of mini-implants retaining an overdenture in the maxilla was observed to be lower than the values reported for traditional implants in the literature. Improvements were observed in all aspects in terms of patient satisfaction, quality of life, oromyofunction, and articulation after the treatment.
微型牙种植体（MDIs）已被用于支持和固位覆盖义齿，为患者提供侵入性较小的植入手术。尽管利润丰厚，但使用MDIs固位上颌覆盖义齿仍不是一种成熟的治疗方式。本系统评价旨在回答以下问题：微型种植体固位的上颌覆盖义齿对全口无牙颌是否能提供令人满意的治疗效果？
对相关文章进行系统检索，纳入截至2021年4月在以下电子数据库中发表的文章：CINAHL、Cochrane、EMBASE、PubMed和Web of Science。所有评估在上颌植入微型种植体固位覆盖义齿后的生物学、存留率或患者报告结局的实证研究均被考虑纳入。采用乔安娜·布里格斯研究所的批判性评价清单评估偏倚风险。研究筛选和数据提取由三位评审员独立进行。
排除重复项后，电子检索共获得1276个标题。20篇文章被考虑进行全文评审，其中6项研究纳入本系统评价。纳入的研究共评估了173名参与者，平均年龄为66.3岁。微型种植体的总体存留率为77.1%（95%CI：64.7 - 89.5%），平均随访时间为1.79年（范围：6个月至3年）。比较全腭覆盖和部分腭覆盖覆盖义齿时，种植体存留情况有显著差异。与部分覆盖覆盖义齿相比，全腭覆盖的种植体总体骨吸收较少。所有研究的参与者均报告，使用MDIs进行修复治疗后生活质量和满意度有所提高。
观察到微型种植体在上颌固位覆盖义齿的存留率低于文献中报道的传统种植体的值。治疗后在患者满意度、生活质量、口颌肌功能和发音等各方面均有改善。
