Peri‐implant tissue definition and registration with a 3D‐printed emergence profile former on titanium stock healing abutment: A dental technique and clinical report

Journal of Prosthodontics, EarlyView.
Abstract 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.
