Background and Objective: Resorption of residual ridge is common problem related to edentulous mandible. One of the main causes of resorption of denture-supporting structures is traumatic or excessive force transmitted through the prosthesis. The resilient-layer and occlusal-reactive dentures are clinical attempts developed for impact reduction and distribution of the masticatory load to the edentulous ridge. Bio-engineered posterior denture teeth which was used in this study have resilient silicone material lining which lead to cushioning effect and reduced the force transmitted to the basal bone. This study was done to assess and compare the masticatory efficiency of complete dentures with bio-engineered teeth and conventional denture teeth using electromyography (EMG) analysis. Methodology: The present study was conducted on 09 completely edentulous patients who reported to the department of prosthodontics and crown and bridge. Two Groups Were Made: Group A - conventional denture and Group B - denture with bio-engineered teeth. All the patients were randomly allotted to Group A or B using random allocation software, after 3 months EMG recording was done, and then, all the patients were provided another set of denture, other than the group in which they had allocated previously. EMG recording was done again after 3 months of providing the denture of other group. Results: Paired t-test showed no statistically significant difference in EMG reading of left masseter (P = 0.514), right masseter (P = 0.545), left temporalis (P = 0.954), and right temporalis (0.944) between both the groups. Conclusion: Both the dentures did not show any statistically significant difference in terms of EMG activity, which indicates that the masticatory efficiency of bio-engineered teeth denture is comparable to that of conventional denture.
