Background: The stability of hard and soft tissues around dental implants is one of the most decisive factors for long-term implant prognosis. The present study was conducted to compare dental implants with different connection configuration. Materials & Methods: 30 patients requiring dental implants of both genders were enrolled. Two groups were made containing 15 patients each. Group I patients were delivered implants with internal friction connection (test group) and group II implants with external hex connection (control group). Implant-supported crowns were delivered at 4 months after implant insertion. Distance from implant shoulder to first bone-to-implant contact (DIB) and peri-implant area were measured. Results: There were 8 males and 7 females in group I and 6 males and 9 females in group II. Smoking was seen among 10 in group I and 9 in group II. 4 in group I and 5 in group II were hypertensive and 3 in group I and 5 in group II were diabetics. Bone quality was 1 seen in 6 in group I and 7 in group II, 2 seen in 5 and 4, 3 in 2 and 3 and 4 in 2 and 1 in group I and II respectively. Gingival width <3mm was seen in 5 in group I and 7 in group II and >3 mm seen in 10 in group I and 8 in group II. The difference was non- significant (P> 0.05). Conclusion: There was chance of the internal friction connection structure for more effective preservation of marginal bone. Key words: Dental implant, internal friction connection, bone-to-implant contact
