- Abstract
Objective: The aim of the present retrospective study was to evaluate the long-term survival rate of dental implants placed in autologous onlay bone block graft (AOBG) augmentation areas, harvested from intraoral origin, used for reconstruction of maxillary atrophy. Patients and methods: A retrospective study was conducted on 108 patients, who received a total of 272 dental implants placed in 109 maxillary augmentation sites using AOBG in combination with platelet-rich plasma (PRP) and bovine bone substitute material, covered with platelet-poor plasma (PPP). Results: Of the 109 OBGs performed from 2000 to 2010, 108 (99.1%) were deemed "successful." Of the total implants, the great majority (94.5%) was deemed to have survived. The total implants' 10-year cumulative survival rate was 89%, compared to 99% in the anterior maxillary area. Conclusions: We suggest that reconstruction of maxillary atrophy, through horizontal and vertical intraoral AOBG, in combination with bovine bone substitute material and PRP and covered by PPP, should be considered a reliable, safe, and very effective method to obtain a high rate of bone graft survival following a high rate of long-term implant survival.
