Background: Severely atrophied ridges are a more common finding with the mandibular residual ridges than the maxilla. The present study was conducted to analyze variation in ridge morphology in edentulous adults. Materials & Methods: The present study was conducted in the department of Prosthodontics on 125 patients with edentulous mandibular ridges. General information such as name, age, gender etc. was recorded. All patients were carefully examined for types of mandibular ridges. Results: Age group 20-40 years comprised of 4 males and 3 females, 40-60 years had 12 males and 11 females, 60-80 years had 14 males and 16 females and >80 years had 30 males and 35 females. The difference was non- significant (P> 0.05).Type I ridge was seen in 12 males and 13 females, type II in 14 males and 16 females, III in 20 males and 14 females and type IV in 14 males and 18 females. The difference was non- significant (P> 0.05). Conclusion: Mandibular edentulism leads to difficulty in eating and speaking. Type III ridges were most commonly seen.
