Alveolar Ridge Regeneration of Damaged Extraction Sockets using a Bovine-derived Bone Graft in Association with a Titanium Foil: Prospective Case Series.

AIMS This study aimed to determine the dimensional change in the alveolar ridge after using an anodized titanium foil (Tseal) in association with bovine bone (BB) grafting in damaged extraction sockets by cone-beam computerized-tomography. MATERIALS AND METHODS Fifteen patients who had one hopeless tooth with over 80% of the buccal wall lost were selected and then the teeth were carefully extracted. The alveolar socket was filled with bovine bone and the Tseal was trimmed and adapted over the bone crest. The primary outcome variable was the change in the alveolar dimension (AD) measurements between baseline (T1) and 6 months (T2) after extraction in three points of analysis, 1mm, 3mm and 5mm below the palatal bone crest. RESULTS Bone regeneration was observed to occur between 87% and 116% of the AD assessed at the baseline. No statistical differences were observed. The mean AD value varied from 7.82±2.75 mm (T1) to 8.02±2.43 mm (T2) in the 1 mm point, from 7.99±2.67 mm to 8.71±2.26 mm to 3 mm and 8.56±2.60 mm to 9.00±2.52 mm at 5 mm area. CONCLUSION Bovine bone graft in association with Tseal achieved horizontal reconstruction of the alveolar crest in compromised socket within 6 months after surgery.
