Soft tissues stability of cad‐cam and stock abutments in anterior regions: 2‐year prospective multicentric cohort study

Abstract

In the anterior area, the use of cad-cam abutments is related to a better soft tissue stability. Such a relationship is significant if cad-cam titanium abutments are compared to both titanium and zirconia stock abutments.

A comparative study of encode protocol versus conventional protocol for restoring single implants: One‐year prospective randomized controlled clinical trial

“…Although the crowns were retained by cross‐pin, leakage and plaque accumulation may still occur and lead to soft tissue redness and inflammation. Such observation corroborates the outcome of earlier studies that reported advantages of the CAD/CAM abutment in maintaining soft tissue contour . Nevertheless, it is important to note that the biological differences between the two protocols were very minor and may not be of clinical significance or lead to biological and esthetic failure.…”

The effect of zirconia or titanium as abutment material on soft peri‐implant tissues: a systematic review and meta‐analysis

“…All studies reported on customized Ti and Zr abutments, and one study also provided data on stock Zr and Ti abutments (Lops et al. ). Due to marked heterogeneity in the study design and quality of reported data, statistical meta‐analysis was only feasible for peri‐implant soft tissue color outcome measure.…”

Esthetic Evaluation of Anterior Single‐Tooth Implants with Different Abutment Designs—Patients’ Satisfaction Compared to Dentists’ Observations

“…It has been proven that the practitioner's perspective is different than that of the patients . The importance of using computer‐aided design and computer‐aided manufacturing (CAD/CAM) to reproduce a favorable shape of the abutment that would support the peri‐implant soft tissue and ensure better esthetics was discussed …”
