Abstract
Purpose The purpose of this study was to evaluate the success rate of dental implant on post-traumatic region to rehabilitate missing teeth. Patients and Methods 5 patients who had been treated due to maxillofacial trauma during 2000 to 2004 at samsung medical center were selected for this study. 22 dental implants were installed to them for restoring missing teeth. The success rate of these dental implants was evaluated with criteria by T. Albrektsson .We divided installed 22 implants into 2 categories. One category consisted rough surface implants group and smooth surface implants group. And the other category consisted more healing group and less healing group. The healing time was calculated from point of trauma. Results The success rate of dental implants is 68.2% that is lower than other studies because of poor vascularity of bone bed and mechanical stress according to trauma. Rough surface implants group and More healing group showed superior success rate to others. (P < 0.05) Conclusion We found that to increase success rate, it may need rough surface implants and longer healing period.
