AIM To evaluate retention of complete denture base with different types of posterior palatal seals. MATERIAL AND METHODS Ten male patients between the age group of 50 years to 60 years were selected for the study. After the primary and secondary impressions were taken, five casts were made including a cast without posterior palatal seal, a cast with single bead posterior palatal seal, a cast ...

STATEMENT OF PROBLEM Currently no data comparing the denture base adaptation of CAD-CAM and conventional denture processing techniques have been reported. PURPOSE The purpose of this in vitro study was to compare the denture base adaptation of pack and press, pour, injection, and CAD-CAM techniques for fabricating dentures to determine which process produces the most accurate and reproducible...

The use of denture base resin has revolutionized the dental material sciences ever since their discovery. Many prostheses and implants made from polymers have been in use for the last three decades and there is a continuous search for more biocompatible and stronger polymer prosthetic materials. In this review, an attempt has been made to combine the material properties of the polymers used in ...

BACKGROUND AND AIMS There are many edentulous people with severely resorbed residual ridges and non-resilient lin-ing mucosa that are unable to tolerate occlusal forces during functional and parafunctional movements. Lining the tissue surface of dentures with a flexible material can theoretically distribute and absorb forces with cushioning effect. The aim of this study was to evaluate the effe...

Purpose: The aim of this study was to evaluate the effect of oral microorganism on surface topography of acrylic resin denture base material. Materials and methods: Fifty rectangular plates of dimensions 30mm x 20mm x 1 mm were fabricated with heat polymerizing acrylic resin denture base material. an area of 10mm x 10 mm in the center of each acrylic plate was marked for evaluation of surface t...

Candida albicans adhesion and proliferation on denture bases may lead to denture stomatitis, which is a common and recurrent problem in denture wearers. The goal of this study was to assess the inhibitory effect of thymoquinone incorporated in the polymethyl methacrylate denture base material against Candida albicans. Eighty acrylic resin specimens were fabricated and divided into eight groups ...

Techniques for bonding denture teeth to acrylic resin denture base remains empirical, with little consensus from the literature, among clinicians or among dental laboratories. Despite of this great variation, the data available regarding effectiveness of various methods used are sparse. The study was carried out to compare the effect of different surface treatments of ridge lap area of acrylic ...
