Buccal bone is relatively thin and bone resorption after tooth extraction in buccal areas is faster. While preparing implant sites in narrow ridges, dehiscence or fenestration defects may occur frequently that threaten the survival of implants. Compared to the lingual bone, especially in the maxillary anterior region, buccal bony housing is thin; thus, bone resorption after tooth extraction in buccal areas is faster and far more prevalent.
To overcome the difficulty of space creation around buccal dehiscence defects, several treatment approaches, such as membranes with GBR or combination of autogenous platelet rich plasma gel with bovine-derived xenograft are often utilized in the buccal dehiscence defects, commonly encountered in sites edentulous for more than 6 months, have been considered to be one of the most challenging defects. In order to provide prolonged space maintenance and wound stabilization in buccal dehiscence defects.
Objectives
1.Presence of dehiscence during implant procedure can be successfully treated by GBR procedures.
2. A simultaneous procedure of implant placement using bone grafts and membranes yield good results. The combination of autogenous platelet rich plasma gel with bovine-derived xenograft showed superiority to bovine-derived xenograft alone .
3. This technique helps in new bone formation and improves the prognosis and prevents failure of implant.
