Abstract
|
|
|
The aim of this study was to investigate the survival and success rates of autotransplanted maxillary canine at the artificially formed recipient socket and evaluate the factors that influence survival and success rates.
A total of 28 children who had 37 impacted canines were reviewed over the mean observation time of 25.1 months. Tooth mobility, pathologic root resorption, vertical bone loss, periapical lesion and anklyosis of donor tooth were investigated clinically and radiographically.
The survival rate was 100%. The success rate was 64.9%, because 13 teeth were evaluated as unsuccessful. Significant parameter in determining the success rate of autotransplantation was enlarged follicle size of donor tooth according to Cox proportional hazard regression model.
The results provide information necessary for clinician to make a better treatment decision about autotransplantation at the artificially formed recipient socket.
