title: Definitive abutment-driven stage-two surgery as a means to reduce peri-implant soft tissue changes: introduction of a new concept.
abstract: This report introduces an innovative approach for optimizing esthetics and minimizing soft tissue changes in clinical scenarios that involve extensive site preparation and submerged implants. The existing soft tissue morphology is registered at the time of implant uncovery, and an optimal peri-implant transmucosal contour is created indirectly in the lab. The customized definitive abutment is inserted during stage-two surgery and subsequently guides the peri-implant soft tissue, replicating an optimal emergence profile. The concept is demonstrated through the presentation of two clinical cases.
