The study is designed as a split-mouth clinical trial and will be conducted in partially or fully edentulous adult patients requiring complete-arch rehabilitation with dental implants.\n\nThe primary objective of the study is to assess the accuracy of implant placement by comparing the virtually planned implant positions with the actual clinical positions achieved after guided surgery. Accuracy will be evaluated by analyzing linear and angular deviations between planned and placed implants.\n\nParticipants will undergo a fully guided implant placement procedure using metal sleeve-free surgical guides. Two different drilling channel diameters (standard and reduced) will be randomly assigned in a split-mouth manner. Postoperative intraoral scans and cone-beam computed tomography (CBCT) scans with scan bodies will be obtained to register the final implant positions.\n\nThe planned and achieved implant positions will be compared using three-dimensional analysis software to quantify deviations and determine whether the use of metal sleeve-free guides and reduced drilling diameters influences implant placement accuracy.",[86],"Edentulism",[88,89,90,91,92],"Guided implant surgery","Dental implants","Surgical guide accuracy","Metal sleeve-free surgical guides","3D-printed surgical guides","2026-01-16",{"date":95,"type":96},"2026-01-23","ACTUAL",{"date":98,"type":96},"2025-10-01",{"date":100,"type":80},"2026-08-01",{"name":5,"class":6},1]
