简要总结
This prospective clinical study evaluated the 3-year performance of mandibular implant-supported overdentures (IODs) placed using a fully guided static computer-assisted implant surgery (CAIS) protocol. Primary outcomes included implant survival, peri-implant soft tissue health, and marginal bone loss. Findings provide evidence for the predictability of digital surgical workflows in removable prosthodontics.
详细描述
Edentulism remains a prevalent global health concern that compromises oral function, esthetics, and quality of life. While conventional complete dentures are widely used, their limitations in mandibular stability often reduce patient satisfaction. Implant-supported overdentures (IODs) offer superior retention and function, but their long-term success depends heavily on precise implant placement.
Computer-assisted implant surgery (CAIS), particularly static fully guided protocols, has been shown to enhance surgical accuracy in fixed prosthodontics. However, evidence for their application in removable prosthodontics remains limited, despite the anatomical and prosthetic challenges often encountered in overdenture cases.
This prospective clinical study was designed to assess the 3-year clinical performance of mandibular IODs placed via a fully guided static CAIS workflow. Outcomes included implant survival, peri-implant soft tissue health, and marginal bone changes. The results provide valuable clinical insight into the role of digital surgical protocols in improving predictability and long-term success of overdenture rehabilitation.

结局指标
主要结局
Implant Survival Rate
时间窗: From prosthesis delivery to 36 months post-loading
Defined as the percentage of implants remaining in function without mobility, pain, infection, or need for removal during the study period. Survival will be evaluated clinically at each follow-up visit.
