The clinical comparisons were performed to evaluate survival rate of 794 endosseous implants that had been inserted between 2004 through 2008 in relation to sex and age of patients, position of implant, implant system and surface characteristics, length and diameter of implant, and bonegrafttechnique.
RESULTS:
The survival rate of implant was 94.3% in posterior area of maxilla and 98.6% in posterior area of mandible by position of implant, a statistically significant difference. As to diameter of implant, survival rate was 98.4% between the 4.0 and 4.5 mm and 75.0% in larger than 5.0 mm, that was statistically significant difference. There was a statistically significant difference regard to bonegraft and surgical technique. The implant survival rate was 89.0% in a placement site which performed sinus lifting, and in case of implant placement with guided bone regenerationtechnique and without bone grafting was 97.6% and 100% each.
CONCLUSION:
According to these findings, this study establishes a relationship between survival rate of implant and position, surface characteristics, diameter of implant and bonegrafttechnique.
