The GBR principle was first examined by Dahlin et al. in 1988 on rats. The selective ingrowth of bone-forming cells into a bone defect region could be improved if the adjacent tissue is kept away with a membrane; this was confirmed in a study by Kostopoulos and Karring in 1994. GBR can be used for bone regeneration on exposed implant coils . [4]
A platelet-rich fibrin (PRF) membrane containing bone growth enhancing elements can be stitched over the wound or a graft material or scaffold is placed in the socket of an extracted tooth at the time of extraction. The socket is then directly closed with stitches or covered with a non-resorbable or resorbable membrane and sutured. [citation ...
The first membranes developed were nonresorbable and required a second surgery for membrane removal some weeks later. The need for a second surgical procedure hindered the utilization of the original barrier membranes, which led to the development of resorbable membranes; [1] research indicates no statistically significant difference in surgical success between the two types.
Xray showing a sinus lift in the left upper jaw Sinus lift surgery, 3D Illustration. Maxillary sinus floor augmentation [1] (also known as a sinus lift, sinus graft, sinus augmentation, or sinus procedure) is a surgical procedure that aims to increase the amount of bone in the posterior maxilla, in the area of the premolar and molar teeth by lifting the lower sinus membrane and placing a bone ...
Others, including Broome and Taggert [4] and Donn [5] also described the use of SECT grafts for increasing the zone of keratinized tissue. Of the various ways of preparing the graft recipient site, Edel described using two vertical incisions, mesial and distal to the teeth at which the zone of keratinized tissue was intended to be widened.

There are two types of skin grafts: Split-thickness skin grafts (the epidermis and part of the dermis) Full-thickness skin grafts (the epidermis and the entire thickness of the dermis) Bone grafting – used in dental implants, as well as other instances. The bone may be autologous, typically harvested from the iliac crest of the pelvis, or ...
Socket preservation or alveolar ridge preservation is a procedure to reduce bone loss after tooth extraction. [1] [2] After tooth extraction, the jaw bone has a natural tendency to become narrow, and lose its original shape because the bone quickly resorbs, resulting in 30–60% loss in bone volume in the first six months. [3]
Indications of alveoloplasty should nevertheless include recontouring or reshaping alveolar bone during tooth extraction surgery. For instance, if alveolar bone has sharp edges after tooth removal, it is necessary to smoothen the bone surfaces to facilitate tooth socket healing process and to avoid any procedural complications such as pain or ...
