Background: The present study was conducted to assess effect of ridge morphology on dental implant treatment outcome. Materials & Methods: The present study was conducted in the department of Prosthodontics. It comprised of 86 patients who received dental implants in mandibular posterior region. Different types of ridge such as undercut type, parallel and convex type was assessed. Number of dental implants failure was calculated. Results: Out of 86 patients, males were 37 and females were 49. Males had 52 and females had 68 dental implants. In 24 patients, ridge was undercut type, in 46 was parallel type and in 16 was convex type. Maximum dental implants failure was seen with undercut type 7 (29.1%) followed by convex type 4 (25%) and parallel in 5 (10.8%). The difference was significant (P< 0.05). Conclusion: Authors found that maximum dental implants were observed with undercut type followed by convex type ridge. Key words: Convex ridge, Dental implants, Undercut type.
