Abstract: The present study was aimed to radiographically compare the crestal bone level adjacent to implant with non platform shift and the platform shift implant with rough surface crestal module at 3 months and 6 months post prosthetic loading. This study was carried out in 10 patients reported to the Department of Oral and Maxillofacial Surgery/ Department of Implantology, Yenepoya dental college, Deralakatte , who require replacement of missing teeth using implant supported prosthesis. Twenty two stage titanium implants [ Ten Nobel Replace® platform shift Tapered implant and ten Nobel Replace Select™ Tapered implant } were placed bilaterally in mandibular posterior region and were radiographically evaluated for crestal bone. IOPA with grid using paralleling technique was taken on the day of placement ,on the day of loading , 3 months after loading and 6 months after loading the implant. Bone loss was evaluated along the mesial and distal surfaces of the implant. The mean crestal bone loss around the perimeter of groups A (non-platform shift) and B (platform shift) at the time of loading was 1.28 mm and 1.16 mm respectively. The mean crestal bone loss around the perimeter of groups A and B implants at three months was 1.4 mm and 1.3 mm. The mean bone loss at six months was 1.61 mm and 1.83 at the mesial and distal aspects respectively in group A. In group B the mean bone loss at six months was 1.3 mm and 1.45 mm at the mesial and distal aspects respectively. The difference in the bone loss at six month is statistically significant with a p value of 0.018 and 0.004. Hence group B i.e the implants with platform switching shows considerably less bone loss than group A.
