Alveolar Ridge Augmentation Following Tooth Extraction Using Bovine Xenograft With Platelet Rich Fibrin Membrane

Alveolar Ridge Augmentation Following Tooth Extraction Using Bovine Xenograft With Platelet Rich Fibrin Membrane

fourteen patients requiring extraction of one posterior tooth with lost buccal bone (>50%) confirmed preoperatively by Cone-beam computed tomography (CBCT) scans. Extraction sockets were filled with minced PRF clots mixed with the bovine xenograft and covered by PRF membranes to seal the extraction sockets. (CBCT) scans, performed before tooth extraction and after 6 months, were used to assess vertical and horizontal bone changes.

Inclusion Criteria:

• Patients required implant treatment after tooth extraction
• Age group ranged from 20-60 years old.
• Patients could undergo the treatment under local anesthesia.
• Loss of buccal bone (>50%) confirmed by preoperative cone beam computed tomography (CBCT).
• Presence of other socket walls; mesial, distal and lingual walls.
• Tooth needed to be extracted in upper or lower posterior regions

Exclusion Criteria:

• Uncontrolled diabetic diseases.
• Uncontrolled hypertension, or hepatic and renal disorders.
• Any systemic diseases associated with bone metabolism.
