Abstract
PURPOSE
The goal of this study was to evaluate the clinical outcome of single short implants, less than 8 mm in length, placed in the posterior area.
MATERIALS AND METHODS
A total of 128 patients (75 male and 53 female, mean age: 52.6±11.2 years) with 154 implants participated. Implant marginal bone loss, and survival and success rates were measured.
RESULTS
The mean follow-up period was 51.35±24.97 months. A total of 128 implants, 8 mm in length, were placed in patients who had mean marginal bone loss of 0.75 mm. These implants had a survival rate of 95.3%. Twenty-six implants, 7 mm in length, were placed in areas with a mean marginal bone loss of 0.78 mm and had a survival rate of 96.2%. Both marginal bone loss and survival rate were not statistically different among the groups. In the maxilla, 34 implants showed a mean marginal bone loss of 0.77 mm and a survival rate of 97.1%. In the mandible, 120 implants showed a mean marginal bone loss of 0.75 mm and a survival rate of 95.0%. The average marginal bone loss around all implants was 0.76±0.27 mm at the last follow-up review after functional loading. The survival rate was 95.6% and success rate was 93.5%.
CONCLUSION
In our study, single short implants less than 8 mm in length in the posterior areas had favorable clinical outcomes.
