Evaluation of Distortion in the Posterior Palatal Seal Area of Maxillary Cast by Different Adaptation Techniques of Denture Bases

AIM: To evaluate and compare the amount of distortion in the posterior palatal seal area in V-shaped and U-shaped palatal form of maxillary cast by different adaptation techniques of maxillary denture bases. MATERIALS AND METHODS: A total of 60 stone casts were made, out of which 30 identical stone...

description AIM: To evaluate and compare the amount of distortion in the posterior palatal seal area in V-shaped and U-shaped palatal form of maxillary cast by different adaptation techniques of maxillary denture bases. MATERIALS AND METHODS: A total of 60 stone casts were made, out of which 30 identical stone casts of U-shaped palatal form and 30 identical stone casts of V-shaped palatal form of maxillary casts were prepared. The 30 stone casts of U-shaped palatal form and 30 stone casts of V-shaped palatal forms were divided into three groups for measurements to be done. Data were statistically analyzed by using two-way analysis of variance (ANOVA) without replication. RESULTS: Discrepancies of fit of dentures on U-shaped casts and V-shaped casts of Groups 1, 2, and 3 in transverse and sagittal sections were measured, and comparative statistical analysis between Group 1&2, Group 1&3, and Group 2&3 was done for statistical significant values. CONCLUSION: Discrepancy in the central region was maximum, and the anchoring methods Group 2 and Group 3 produced a significantly better adaptation than the conventional method (Group 1). The adaptations for V-shaped palate were better when compared with U-shaped palate in the central region.
