Background: The timing of implant placement has changed over a period of time with advancement in clinical techniques and introduction of novel biomaterials of dental implants The short-term survival rate of implant placement seems similar between immediate, early, and delayed approaches. Material and methods: The present study was undertaken for analysing the outcome of Single Tooth Implant in healed Extraction Site. A total of 40 patients were selected for this study who underwent an extraction atleast 3 months before reporting for tooth replacement. All demographic details of the patients were recorded. Radiograph of the healed extraction site was taken to ascertain proper bone healing and remodelling. Patients were thoroughly evaluated for medical and clinical findings. A pre-operative radiographic assessment was carried out. Soft tissue contour and texture was evaluated at the healed extraction site. An immediate post implant placement radiograph was also taken. At follow up appointments proper clinical and radiographic assessment was carried out to evaluate bone levels around implants and soft tissue heath was also verified. Results: At 6 months follow up an intact mesial interproximal papilla was seen in 28 out of 40 patients(70%). 30% cases showed loss of mesial interproximal papilla. Similarly, at 6 months follow up an intact distal interproximal papilla was seen in 26 out of 40 patients(65%). 35% cases showed loss of distal interproximal papilla. . At 1year follow up an intact mesial interproximal papilla was seen in 31 out of 40 patients(77.5%). 22.5% cases showed loss of mesial interproximal papilla. Similarly, at 1 year follow up an intact distal interproximal papilla was seen in 29 out of 40 patients(72.5%). 27.5% cases showed loss of distal interproximal papilla. Mean marginal bone loss at 6 months and 1 year follow up was .69±.33mm and 1.13±.28mm respectively. Conclusion: This study concluded that delayed placement of implant in a healed extraction socket is more predictive than immediate placement of dental implants.
