Background: Edentulous patients suffer from a variety of problems with their dentures, especially with regard to the lower denture, such as insufficient stability, retention and pain during mastication. For many years, traditional complete denture designs have been modified to gain additional support and stability from a few retained and suitably prepared natural teeth. Hence; the present study was planned to evaluate the extent to which immediate tooth and implant-supported overdentures would aid beneficially to preserve occlusal vertical dimension. Materials & methods: For the study, 9 patients were selected having age range of 44-67 years, with mean age of 56 years. The selected patients were randomly grouped into three groups with 3 patients in each group. Group 1: three patients receiving conventional acrylic immediate complete mandibular denture (mucosal-supported); Group 2: three patients who will be receiving acrylic immediate complete mandibular denture supported by reduced root canal treated canines (tooth-supported). Group 3: three patients who will be receiving acrylic immediate complete mandibular denture supported by osseo-integrated fixtures in the canines region (implantsupported). For determination of changes in occlusal vertical dimension for patients in all groups; lateral cephalometric radiographs were taken to detect occlusal vertical dimensional changes. The data collected from different groups was analysed using SPSS software for windows. Results: The analysis of the mean differences in occlusal vertical dimension for all groups,i.e.,Group1, Group 2, and Group 3 was done at Time 1, Time 2 and Time 3 with the help of lateral cephalometric radiographs taken at different intervals. The mean occlusal vertical dimension changes in Group 1 were -0.43+0.076 in time 1, 0.84+0.217 in time 2, and -3.02+0.521 in time 3; in Group 2 were -0.39+0.079 in time 1, -0.80+0.221 in time 2, 1.43+0.193 in time 3; in Group 3 were -0.41+0.154 in time 1, -0.82+0.216 in time 2, -2.23+0.324 in time 3. Conclusion: The biting force of masticatory muscle is functionally dependent on maintenance of muscle health and occlusal vertical dimension.
