Retention of CAD-CAM locator retentive attachment insert in mandibular implant overdenture.

Background: The continuous development in digital prosthodontics allowed the customization of attachments and retentive inserts which offers an easy and cheap solution for regular maintenance of locator overdentures during daily practice. The present study compared the change in retention values of the fully digitally manufactured custom-made locator attachment retentive insert with the ready-made ones after insertion, removal, and masticatory cycles.

Methods: A complete denture was constructed over a mandibular edentulous epoxy model.

Computer guided versus freehand dental implant surgery: Randomized controlled clinical trial.

Objective: This study compares, in terms of rehabilitation and recovery, freehand implant placement using flapless or mini-flap procedures with the use of 3D implant design software and specialized surgical templates among patients who are partially or completely edentulous. A secondary aim is to propose an algorithm for predicting the accuracy of implant placement. Method.
