Methods: This Study was designed as a cross sectional study. Consecutive patients affected by jaw's atrophy and treated with implants placement, simultaneous block bone graft between 2008 to 2011, were recalled. 87 patients (42 male, 45 females) aged between 22 and 70 years were enrolled. A total of 194 implants were inserted in 110 surgery sites. During the recall, new X-Rays were requested and a clinical evaluation was performed. The outcome measures were “Implant Success”, “Implant Satisfactory Survival”, “Implant Compromised Survival”, and “Implant Failure”. The follow up period was 19.7±6.2 months.
Results: Of the 194 implants placed simultaneous with block bone graft, 178 implants in 84 patients carried ideal conditions. The amount of crestal bone loss of 10 implants in 7 patients was evaluated 2.6±0.5 mm. 4 mm C.B.L occurred for 3 implants in 3 patients, also a slight to moderate peri-implantitis was observed. 3 implants failed in 3 patients. The outcome was recorded as follows: Implant Success rate: 91.8%; Implant Satisfactory Survival rate: 5.2%; Implant Compromised Survival rate: 1.5%; and Implant Failure rate: 1.5%.
Conclusions: Based on the results, with necessary precautions, it can be concluded that implant placement in conjunction with block bone graft simultaneously represents a safe modality of treating the atrophic maxilla/mandible.
