The preoperative fabrication of well-contoured, computer-aided design and computer-aided manufacturing (CAD-CAM), custom healing abutments is essential for guiding soft tissue healing and saving chairside time. This dental technique involves a fully digital workflow to fabricate a CAD-CAM custom healing abutment that relies on preoperative digital implant planning. The healing abutment is designed with an optimal emergence profile that can predictably direct the anatomy of the peri-implant mucosa.

Objective: This study aimed to assess the fracture resistance of chairside computer assisted design and computer assisted manufacturing (CAD-CAM) lithium disilicate partial and full-coverage crowns and veneers for maxillary canines.
Methods And Materials: Forty-eight restorations for maxillary right canines (12 per group) were designed as follows: (1) partial crown with finish line in the upper middle third; (2) partial crown with finish line in the lower middle third; (3) traditional labial veneer; and (4) traditional full-coverage crown. Restorations were fabricated out of lithium disilicate (Amber Mill, Hassbio) using a chairside CAD-CAM system (Cerec Dentsply Sirona).
Peri-implant tissue definition and registration with a 3D-printed emergence profile former on titanium stock healing abutment: A dental technique and clinical report.

Recent focus has shifted toward refining the soft tissue emergence profile to enhance aesthetics, support peri-implant health, and ensure long-term success. Traditionally, titanium stock healing abutments or chairside-customized abutments were used to shape peri-implant tissues and develop the emergence profile for implant-supported prostheses. However, advancements in digital dentistry now allow for more precise customization and increased treatment efficiency.

Statement Of Problem: Comprehensive data are needed on the performance of chemically activated, chairside hard reline materials when used with computer-aided design and computer-aided manufacturing (CAD-CAM) milled polymethyl methacrylate (PMMA) denture bases and conventionally processed bases. This lack of data affects decisions regarding the chairside reline material to be used for improving the fit and retention of relined complete dentures.
Purpose: The purpose of this in vitro study was to evaluate and compare the shear bond strength (SBS) of 3 chemically activated, chairside hard reline materials on CAD-CAM milled and conventional heat-polymerized PMMA denture bases.
Two-Year Clinical Evaluation of Enamel Wear Antagonistic to Polished and Glazed Monolithic Zirconia Endocrowns.

Department of Fixed Prosthodontics, Faculty of Dentistry, Mansoura University, Mansoura, Egypt.
Objective: To assess the effect of chairside adjustment and polishing on the clinical performance of zirconia endocrowns and digitally calculate the opposing enamel wear.
Materials And Methods: A total of 20 participants received zirconia endocrowns on their endodontically treated lower first molars. All endocrowns were fabricated using CAD/CAM technology.
