To compare implant fixed complete dentures with implant overdentures relative to prosthodontic outcomes.
An electronic Medline (PubMed) with MeSH terms, and Cochrane library search was performed, focusing on studies that included implant fixed complete dentures and implant overdentures in the same study, with the results based on studies that included both types of prostheses.
The following six categories of comparative studies were identified in the literature: 1) Implant and prosthesis survival; 2) Prosthesis maintenance/complications; 3) Bone changes; 4) Patient satisfaction and quality of life; 5) Cost-effectiveness; and 6) Masticatory performance. It was determined that both the fixed and removable treatments were associated with high implant survival rates. However, both types of prostheses were impacted by the need for post-placement mechanical maintenance or prosthetic complications. More maintenance/complications occurred with implant overdentures than with fixed complete dentures. Residual ridge resorption was greater with implant overdentures. Patient satisfaction was high with each prosthesis, with three studies revealing higher satisfaction with fixed complete dentures and five studies finding no difference. All but one study on cost-effectiveness indicated implant overdentures were more cost-effective. Based on two studies, it appears the masticatory performance of implant fixed complete dentures and implant overdentures is comparable.
Multiple factors must be considered when determining whether an implant-fixed complete denture or implant overdentures are best suited for patients with completely edentulous jaws. Conflict-of-interest statement: The authors declare they have no conflicts of interest.
比较种植体固定全口义齿和种植体覆盖义齿的修复效果。
通过电子医学文献数据库（PubMed）及Cochrane图书馆，以医学主题词进行检索，重点关注同一研究中包含种植体固定全口义齿和种植体覆盖义齿的研究，并基于包含这两种修复体的研究结果进行分析。
在文献中确定了以下六类比较研究：1）种植体与修复体的存留率；2）修复体维护/并发症；3）骨变化；4）患者满意度和生活质量；5）成本效益；6）咀嚼性能。结果表明，固定修复和可摘修复治疗的种植体存留率均较高。然而，两种修复体都受到放置后机械维护需求或修复并发症的影响。种植体覆盖义齿的维护/并发症比固定全口义齿更多。种植体覆盖义齿的剩余牙槽嵴吸收更明显。每种修复体的患者满意度都较高，三项研究显示固定全口义齿的满意度更高，五项研究未发现差异。除一项成本效益研究外，所有研究均表明种植体覆盖义齿更具成本效益。基于两项研究，种植体固定全口义齿和种植体覆盖义齿的咀嚼性能似乎相当。
在确定种植体固定全口义齿或种植体覆盖义齿是否最适合全口无牙颌患者时，必须考虑多个因素。利益冲突声明：作者声明他们没有利益冲突。
