Background: Immediate implant placement into fresh extraction sites is the most advanced treatment modality. The use of a connective tissue graft will be first described for immediate implants, as a biological barrier to cover the residual alveolar defect with an immediate implant, allowing for the undisturbed healing of Peri-implant deep tissues. Hence; the present study was undertaken for clinically and radiographically evaluating crestal bone level around immediate implants with and without connective tissue graft. Materials & Methods: 30 patients were randomly allocated to the immediate implant without connective tissue graft group (n-15) or the immediate implant with connective tissue graft group (n-15).The implants in the immediate group were placed on average immediately following tooth extraction. The tooth in question was extracted using a method involving minimal trauma to the bone and surrounding soft tissues. Asulcular incision along the buccal aspect of the planned implant site and a vertical bevelled releasing incision to spare the adjacent papillae were given. A full-thickness flap was elevated and extended beyond the anticipated apical extension of the pre -planned implant length. The stability of the implant and health of the peri-implant soft tissue were clinically evaluated at baseline, three months and six months and nine months after implant placement. Results: Mean values of plaque index showed an increase from third to sixth month and then decreased in ninth month. This pattern was observed in both the control (without CTG) and test (with CTG). Results showed slightly higher mean difference of width of keratinized gingiva in baseline to third month than in baseline to sixth month and baseline to ninth month intervals and this difference were found to be statistically significant. Conclusion: Immediate implant placing reduces alveolar resorption. The use of connective tissue graft (CTGs) has improved the esthetic outcome of dental implants, mainly due to enhancing alveolar bone contours. Key words: Dental, Implant, Graft
