Objective To evaluate the curative effect of dental implant by crownless bridge works (CBW). Methods The index of gingival bleeding, the index of tooth loosing and successful rate of dental implant by CBW and common dental implant on 60 rabbit models was investigated on 1, 2, 3, 6, 9, 12 month. Results The survival rate of dental implant by CBW was higher than that of common dental implant. Conclusion The dental implant by crownless bridge works can reduce the pressure to the bone and improve the successful rate of implant.
