Maintenance of Soft Tissue Closure Following Guided Bone Regeneration: Technical Considerations and Report of 723 Cases

Abstract

The purpose of this paper is to present simple clinical techniques which have been utilized in a significant number of consecutive cases to maintain primary closure throughout the course of regeneration. The maintenance of soft tissue primary closure following guided bone regeneration (GBR) therapy, while considered a considerable challenge, is recognized as contributing to the maximization of therapeutic results. A retrospective analysis of the maintenance of such soft tissue primary closure following the utilization of specific mucoperiosteal flap designs during GBR surgery in 723 consecutively treated cases was carried out. Soft tissue closure was maintained over the membranes for the course of regeneration (a minimum of 6 months) in 695 cases (96.1%). The maintenance of soft tissue primary closure following GBR therapy may be predictably attained through proper surgical planning, technical care, and appropriate postoperative management.

Role of collagen membrane in lateral onlay grafting with bovine hydroxyapatite incorporated with collagen matrix in dogs

“…Furthermore, it has been demonstrated consistently that the grafted site for GBR may be completely separated and protected from the external environment by the periosteum [4]. It has been indicated that using periosteal flaps as the primary closure for graft materials can promote both wound healing and the creation of new bone [5].…”

Complications When Augmenting the Posterior Maxilla

“…53,54 Although bone regeneration can be achieved without attaining and maintaining passive soft tissue primary closure over the regenerating site, the extent and morphology of the regenerated hard tissues often fall short of the desired ideal treatment outcome. In addition, the resultant soft tissue covering when passive soft tissue primary closure is not maintained is usually thinner than desired and represents a potential aesthetic compromise.…”

Preservation of keratinized mucosa around implants using a prefabricated implant-retained stent: a case-control study

“…In contemporary implant treatment, the necessity of guided bone regeneration (GBR) has increased due to the concept of contour augmentation, and frequent GBR procedures usually lead to the reduction of keratinized mucosa around implants, since the flaps have to be advanced for tensionless primary closure [56]. To correct these mucogingival issues, a free gingival graft (FGG), an apically positioned flap, or a connective tissue graft is required if there is a minimal width of keratinized tissue, in order to increase the width [7].…”
