Objectives: To determine the residual ridge morphology and resorption for treatment of edentulous patient with complete denture in Melmaruvathur population. Methods: 100 completely edentulous subjects with age between 45 – 75 years have been included in the study. A standardized panoramic radiograph was made for all patients. Measurements were made digitally using RadiAntDicom viewer software and the amount of resorption was calculated using the Wical and Swoope method. Statistical analysis was done using NPar test and MannWhiteney analysis. Level of significance was set at 0.02. Result: According to Wical and Swoope classification, study subjects were divided and results were obtained. class I-Mild resorption, Class II-moderate resorption. Class III-severe resorption and the frequency is 0,25,75 respectively. When comparing the age groups, there were increase in rate of resorption with increase in the age. The results were found to be less statistically significant (p value is 0.002). When comparing the gender, the resorption rate is increased in females than males. Conclusion: With an increase in age, there is an increase in the amount of residual ridge resorption. The amount of resorption in females is found to be more than that of males.
