Radiographic Evaluation of Bone Resorption Rate 1 Year After the Placement of Intra-lock Dental Implants

The aim of this study was to investigate the alveolar bone loss, using periapical radiographs, right after the implantation and also one year after the prosthetic delivery in intra-lock dental implant.

Digital periapical films of 164 intra-lock implants which were taken immediately after the surgery and one year after the prosthetic restoration between 2015 and 2017 were used in this study. All of the radiographs were taken by Rad Radiography Center in Ardabil and were implanted by Dr. Sigari (private office in Ardabil). Out of the 164 individuals, 80 (48.8%) were male and 84 (51.2%) were female. Their age ranged between 16 to 81 years old and the highest frequency belonged to the age group of 31-40 years old and the lowest frequency belonged to those who were under 20 years of age.

Mean bone loss was 1.87 mm one year after prosthetic delivery. The average bone loss was higher in the posterior upper jaw and total failure of this implant was observed only in 6 cases. No significant difference in the bone loss was observed between females and males (P= 0.221). The lowest mean bone resorption was observed in the age group of below 20 years. The highest mean bone resorption was observed in the posterior maxilla. Out of 164 patients, 158 (96.3%) had permanent implants and 6 (3.7%) had implant loss.

Within the limitations of this study, the mean bone loss in this brand was acceptable and Blossom Technology can find its way to the market, thus we found this brand with new technology useful for clinical application
