This study was done to Evaluate the effect of early loading and immediate loading of dental implants on bone and supporting periodontium. The posterior partially edentulous mandible at first molar area was used as implant recipient site. The surgical phase was done with the aid of surgical stent that gave precise results in implant insertion. This stage included fixture insertion in the site of the first molar. The fixture was loaded immediately (immediate loading) or after one month (early loading) with temporary restoration. Then left to heal for four months before final restoration. The follow up of the patients was done after prosthesis cementation as a base line, 3 months, 6 months and 9 months. The radiographic examination included measurement of marginal bone loss on the mesial and distal side and bone density around the fixture. Both the clinical and radiographic assessment revealed that both early loaded dental implants and the immediately loaded implants was in the acceptable range.
