Comparison of crestal bone changes bucco-lingually after immediate and delayed implant placement: a clinico-radiographic study

KWN4B ePOSTER CLINICAL RESEARCH – PERI-IMPLANT BIOLOGY

Background: Implants are becoming a predictable alternative for routine replacements in edentulism. Immediate implant placement seems to offer several advantages without compromising the quality of results achieved by the delayed implants. This is a comparative clinical and radiographical study which includes immediate implant placement and the implants placed after 6-8 weeks of healing period post extraction, comparing bucco-lingual crestal bone changes.

Aim/Hypothesis: The aim the study was to compare Bucco-lingual crestal bone changes, clinically and radiographically after immediate and delayed implant placement.

Materials and Methods: A total of fifty patients were included in the study and were equally divided into two groups. In group A, immediate implants were placed whereas, in group B, implants placement were delayed by six to eight weeks. Bucco-lingual width was measured at the time of implant placement and during abutment placement. Bone grafts were used only in cases where jumping distance was more than 1.5 mm. All the clinical parameters and CBCT readings were recorded by the same examiner.

Results: All the implants were placed without any mobility and achieved osseointegration successfully. Immediate implant group showed a mean width of 8.80 mm (SD2.280) at the time of implant placement whereas, 7.60 mm (SD 1.871) after six months. Delayed implant group showed a mean width of 8.40 mm (SD1.673) at the time of implant placement, and 7.40 mm (SD 1.658) after six months. Intragroup showed statistically significant data (P < 0.05). When the intergroup comparison of group 1 and group 2 was made at implant placement day and abutment placement day, it was found to be statistically NO-significant.

Conclusions and Clinical Implications: The data suggest that healing in both groups was equally good. So, one should opt for immediate placement of implant which will preserve bone, soft tissue architecture and esthetics. It will also increase patient's comfort, save the need for a new surgical intervention and reduce the treatment cost and time.
