Abstract
Purpose: This study was conducted to compare the adaptation accuracy of distolingual flange of mandibular complete dentures fabricated by versacryl and soft acryl
Material and methods: 14 lower completely edentulous casts with bilateral distolingual undercut were duplicated from mandibular completely edentulous patient.14 Mandibular complete dentures were processed with Conventional heat cure acrylic resin denture base except the distolingual flange. Dentures were divided into two equal groups: Soft acryl Group at the distolingual flange and Versacryl group at the distolingual flange. The gap between the denture and the cast at the distolingual undercut was measured at three points (A,B,C)using Stereo microscope.
Result : The result of this invitro study revealed that median gap width value of soft acryl group (733.2) and IQR 224.65 to median gap width value of Versacryl group (1256.748)and IQR(1039.2) regardless of the location. The Versacryl group showed statistically significant higher median gap width value than soft acryl group with p value = 0.00
Conclusion : Within the limitation of this invitro study, the gap distance found when using versacryl in the disto lingual undercut, was greater than the gap distance found with the use of soft acrylic. Soft acryl as denture base showed more adaptation comparing to the versacryl as the distolingual flange of in lower complete denture.
