Abstract

Objectives: To evaluate the implant stability changes associated with immediately loaded implants with specific knife-edge threads versus implants with conventional threads inserted in the posterior maxilla.

Materials and methods: Twenty patients were selected for prosthetic replacement of missed maxillary posterior single tooth by a dental implant. Patients of this study were selected after approval of the Research Ethics Committee with code (A15030821). All patients were divided into two equal groups: Group 1 (Control group): Ten patients received 10 implants of conventional thread design. Group 2 (Study group): Ten patients receiving 10 implants with specific wide knife-edge thread design. Clinical evaluation of implant stability was performed at the time of implant insertion and the 3rd, 6th, and 9th week then after 3 and 6 months. Radiographical evaluation of marginal bone level (MBL) and relative bone density (BD) were performed immediately postoperative and after 6 months of implant loading using CBCT. All clinical and radiographic data were subjected to statistical analysis.

Results: There were statistically significant differences between both groups regarding implant stability at the time of insertion only (P

Conclusion: Although modification of implant threads macro-design can result in short-term improvement of primary stability by reducing lag phase, however no further superior impact was revealed on other clinical parameters.
