Immediate Implant Placement and Provisionalization in the Esthetic Zone Revisited: The Marginal Migration Concept (MMC)

Abstract

Immediate implant placement and provisionalization in the esthetic zone is a desirable approach that presents several advantages but at the same time embosses several risk factors that can lead to sever esthetic complications. The purpose of this article was to propose a new protocol that could allow for the maintenance and even the improvement of the hard and soft tissue topography, leading to superior esthetic results. The proposed protocol, when certain criteria are met, could be applied even for cases where the extraction socket morphology is currently proposed as a contra-indication for immediate implant placement and provisionalization.
