Abstract

This study aimed to investigate the factors that affect marginal bone loss after the prosthesis delivery of a dental implant with an internal conical connection and a sandblasted, large-grit, acid-etched surface and to compare and investigate the marginal bone loss of dental implants and adjacent teeth in the same interproximal unit. Radiographic measurements using panoramic radiographic images obtained at 1 year and final follow-up (minimum 2 years) were performed to measure the marginal bone loss of the dental implant and adjacent teeth and the distance between them. The arch in which the dental implants were placed significantly affected the marginal bone loss of dental implants at the final follow-up (maxilla>mandible, p<0.05). At each period, the dental implants showed significantly less marginal bone loss (p<0.05) than adjacent teeth. Dental implants placed >4 mm away from adjacent teeth showed significantly less marginal bone loss (p<0.05).
