Introduction: Oral bone loss adversely affects the masticatory muscle activity, especially in elderly patients. Osteoporosis, which leads to decreased bone mineral density in facial skeleton, has been seen to cause atrophic changes in the muscles of mastication. In edentulous patients, these changes tend to be more pronounced, in return decreasing the chewing efficiency and function of complete dentures.

Methodology: A total number of 80 test subjects (44 non-osteoporotic and 36 osteoporotic) were enrolled to evaluate the effect of osteorporosis on the electromyographic activity of masticatory muscles (Masseter and Temporalis) after being rehabilitated with complete dentures in both the maxillary and mandibular arch.

Result: A comparative assessment of amplitude (indicating electromyographic activity of the masticatory muscles) between osteoporotic and non-osteoporotic groups revealed lower values in osteoporotic subjects than normal subjects for both Masseter and Temporalis. The results were statistically significant (Masseter p=0.005 and Temporalis p=0.03).

Conclusion: Osteoporosis may produce significant adverse effects on the masticatory function of complete denture wearers. As a future prospect, we might allow for proper treatment protocol to be followed to improve the bone mineral density of the osteoporotic patients and evaluate any changes in electromyographic activity in edentulous patients.
