Abstract

Abstract: Objective To evaluate the clinical effect of filling the bone gap with autogenous bone gotten from immediate implant site by cone beam computed tomography (CBCT). Methods Total of 32 patients (32 single anterior teeth that should be extracted) were divided into two groups with stratified randomization. Test group (16 cases):got the autogenous bone from extraction site with trephine and then implanted, filled the crushed autogenous bone into the gap around the implant, placed the healing cap or took immediate restoration and sutured the wound. Control group (16 cases):performed immediate implant after extraction, filled Bio-Oss Collagen into the gap, placed the healing cap or took immediate restoration and sutured the wound. CBCT should be taken after 6 months, compared the alveolar width and height with preoperative. Results The success rates of the two groups were 100%. Inter-group comparison between the two groups showed no significant difference in the change of alveolar width and height of labial and palatal bone plates before and 6 months after operation (P>0.05). Intra-group comparison in both groups showed significant difference in the alveolar width and height of labial and palatal bone plates before and 6 months after operation (P<0.05). Conclusion The method of filling the bone gap with crushed autogenous bone gotten from immediate implant site was simple and practical, which could obtain good clinical effect.

Key words: immediate implant, trephine, autogenous bone, cone beam computed tomography(CBCT)
