Bone Surrounding The Extracted Socket Space.

DISCOVER MORE

After a tooth is extracted, healing of soft tissues and bone follows. Without preservation of the extraction site, the bone surrounding the extracted socket space gradually resorbs, resulting in soft and hard tissue defects. This reduction in quantity & quality of bone, is a source of problem for future treatment options like dental implants or prostheses, affecting their functional and esthetic outcomes.

Although the process of resorption of dental ridges after extraction is unpredictable, predominant horizontal bone loss affecting the buccal bone of the ridge is the pattern majorly observed. Due to this resorptive pattern, a lingually inclined, atrophied ridge is the result.

To combat these hard and soft tissue defects after tooth extraction, bone grafting for site preservation is the solution.
Research has shown that the sockets preserved with bone grafting on average lost 2 mm less of ridge width, 1 mm less of ridge height, and were found to have 20% more bone volume compared to sockets that were not grafted.
