Aims and Objectives: Residual ridge resorption is perplexing problem for complete denture patients and so with the Prosthodontist.It is of multifactorial origin where it is termed as a chronic, progressive, irreversible and disabling disease. Several methods have been devised to measure the RRR like cephalometrics, dent contourographs, casts, photogrametrric method etc but the method described by Wical and Swoope is simple, useful method for arriving at gross estimate the amount of RRR. Thus this method was used in this study with the objective to investigate the amount of mandibular ridge height in relation of aging and length of edentulism. Materials and Methods: The study was limited to men to overcome variables associated with osteoporosis and menopause in women. 60 complete denture wearers' male patients were selected from the department of Prosthodontics, K.L.E.S's institute of dental sciences, Belgaum. The groups were divided into two resorptive age groups those between 40 to 60 years of age and those over 60 years of age. Each patient was informed about the study and after obtaining informed consent an OPG was made. Then the measurement was made on OPG using Wical and Scoope method to determine the ridge height in relation to age and edentulism period. Results: To test measurement significance one way analysis of variance (ANOVA) was applied between the resorptive age groups and within resorptive age groups. A significant P=0.00086 value was obtained in younger resorptive age group but it was non significant P=0.1223 was obtained in older resorptive age group. A student unpaired t-test was used to measure the significance between the resorptive age groups for the same edentulism period. Conclusion; Within the limitations of this study it was concluded that the mandibular ridge height reduction was linear throughout the ages.
