Effect of CAD/CAM Abutment Morphology on the Outcomes of Implant Therapy: A Randomized Controlled Trial.

ABSTRACT:

Objectives

Variations in transmucosal abutment contour design may affect the outcomes of implant therapy. This randomized controlled trial was primarily aimed at testing the effect that CAD/CAM zirconia abutments with either a concave or linear divergent transmucosal morphology have on peri-implant mucosal dynamics and indicators of peri-implant health at 1 year after final implant-supported prosthesis insertion in the anterior maxilla.

Materials and methods

Following computer-guided implant placement and osseointegration, eligible subjects were randomized into either the experimental (concave morphology) or the control (linear divergent morphology) group. A comprehensive set of outcomes of interest related to peri-implant soft tissue dynamics, phenotypical features, and ind
