Abstract:
:The purpose of the present investigation was to determine the long-term prognosis of autotransplanted premolars with respect to periodontal healing. The subjects consisted of 195 patients aged 7 to 35 years, with a total of 370 autotransplanted all operated and followed with a standard technique. The observation period ranged from 1 to 13 years. Periodontal healing as demonstrated radiographically was complete in most cases after 8 weeks. Root resorption occurring after transplantation was divided into surface-, inflammatory- and replacement resorption (ankylosis). Root resorption occurred in 52 of the transplanted teeth and was usually diagnosed within 6 months. Root resorption was found to be significantly related to increasing stage of root development and the stage of eruption at the time of transplantation. Subsequent orthodontic movement of teeth with completed root formation at the time of transplantation resulted in a slight increase in the frequency of both surface and inflammatory resorption. The present study indicates that trauma to the PDL of the transplant is the explanatory factor for the development of root resorption.
