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

Although connective tissue grafts (CTGs) have been found to increase gingival thickness and reduce facial gingival recession in immediate implant placement and provisionalization (IIPP), they are associated with significant loss of buccal bone thickness. This loss is thought to be related to the preparation of the facial CTG recipient site. This technical report presents a modified dual-zone therapeutic concept in which the bone zone is grafted with bone graft and the tissue zone is grafted with tuberosity CTG without elevation of a facial partial- or full-thickness envelope.
