Summary

Tooth extraction is among the most common dental treatments. The procedure results in the formation of a bone defect. During the healing phase, the vertical and horizontal diameters of the alveolar ridge decrease, which has a negative impact on planned prosthetic or implantoprosthetic therapies.

The socket preservation technique involves filling the socket with an augmentation biomaterial to reduce vertical and horizontal alveolar atrophy. This prospective clinical study compares two biomaterials suitable for alveolar ridge preservation: xenogeneic versus allogeneic. Histological analysis and radiographic parameters related to the dimensions of the alveolar ridge and bone optical density are evaluated during a 180-day follow-up period.

Conditions

  • Socket Preservation
  • Alveolar Ridge Preservation
  • Xenograft
  • Allograft
  • Extraction Socket Healing

Interventions

PROCEDURE

Socket preservation with xenograft

Minimally invasive tooth extraction with separation is performed. The wound is debrided and the socket is filled with xenogeneic biomaterial (Geistlich Bio-Oss®, cortico-cancellous bone powder, 0.25-1 mm granules) up to the alveolar crest. This is then covered with a Geistlich Bio-Gide® collagen membrane and sutured with 4-0 nylon sutures. An open healing protocol is utilised. Standardised postoperative care, antibiotics and follow-up are provided. CBCT scans with a 5x5 cm field of view are performed preoperatively, and again after 7-10 days and after 180 days of treatment.

PROCEDURE

Socket preservation with allograft

Minimally invasive tooth extraction with separation is performed. The wound is debrided and the socket is filled with allogeneic biomaterial (BIOBank®, cortico-cancellous bone powder, 0.5 mm granules) up to the alveolar crest. This is then covered with a Geistlich Bio-Gide® collagen membrane and sutured with 4-0 nylon sutures. An open healing protocol is utilised. Standardised postoperative care, antibiotics and follow-up are provided. CBCT scans with a 5x5 cm field of view are performed preoperatively, and again after 7-10 days and after 180 days of treatment.
