Assessment of Residual Ridge Resorption in Mandible of Edentulous Patients

Residual Ridge Resorption (RRR) is a common and often incapacitating problem, particularly in edentulous mandible. Reduction of residual ridges needs to be recognized for what it is: A major unsolved oral disease that causes physical, psychological, and economic problems for millions of people all over the world. The aim of this study was to evaluate the residual ridge resorption in mandible of edentulous patients. To find the mean residual ridge resorption in mandible of edentulous patients.

All patients who fulfilled the inclusion criteria and underwent prosthodontic rehabilitation at Fatima Memorial Dental Hospital, Lahore were included in the study. After ethical approval, informed and written consent was taken. A brief history was taken, clinical examination conducted and the residual ridge resorption (RRR) of the mandible was evaluated on 3D Cone Beam Computerized Tomography CBCT to assess the outcome that is mean RRR of the mandible.

A total of 60 edentulous patients were included. 37 (61.7%) patients were males while 23 (38.3%) were females with the mean age of 59.1167+5.489 years. The mean ridge residual resorption was 24.283+3.975 mm.

The residual ridge resorption increased with increase in age, duration of edentulism and was more in males than in females.
