About this trial
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.
