Modified Dual-Zone Therapeutic Concept of Single Immediate Implants with Bone Augmentation of the Bone Zone and Soft Tissue Augmentation of the Soft Tissue Zone: Technical Report with 3 Cases.

Abstract

While the addition of a connective tissue graft (CTG) has been found to increase gingival thickness and reduce facial gingival recession in immediate implant placement and provisionalization, it is associated with significant loss of buccal bone thickness. Loss of buccal bone thickness is thought to be related to preparation of the facial CTG recipient site. This technical report presents a modification of the dual-zone therapeutic concept where the bone zone is grafted with bone graft, and the tissue zone is grafted with tuberosity CTG without elevation a facial partial or full-thickness envelope.
