Accuracy of Half-guided Implant Placement

Semmelweis University40 enrolled

Overview

The aim of the present prospective randomized controlled study is to compare the accuracy of implant placement performed either with a surgical motor or a torque wrench as part of a half-guided surgical protocol after maxillary sinus floor augmentation.

Implant insertion with half-guided surgical protocol was utilized by surgical motor (machine-driven group) or torque wrench (manual group) in the maxilla. Forty patients were randomly divided in two study groups; 20 implants were inserted with a surgical motor and 20 implants with a torque wrench. After the healing period, accuracy comparison method between planned and actual implant positions was performed based on digital intraoral scan. Coronal, apical and angular deviation parameters, insertion time and maximum insertion torque was evaluated.
