Effect of silica coating and silane surface treatment on the bond strength of soft denture liner to denture base material
OBJECTIVE This study investigated the effects of different surface treatments on the tensile bond strength of an autopolymerizing silicone denture liner to a denture base material after thermocycling. MATERIAL AND METHODS Fifty rectangular heat-polymerized acrylic resin (QC-20) specimens consisting of a set of 2 acrylic blocks were used in the tensile test. Specimens were divided into 5 test ...
متن کاملDeveloping the procedure of modifying the denture soft liner by silver nanoparticles.
Colonization of denture soft lining materials by fungi and denture plaque leads to infections of mucosa. Microorganisms such as Candida albicans colonize not only the surface of the soft liners, but they also penetrate inside those materials. Therefore the use of common disinfectants, e.g., surface active cleaners, is not a perfect solution for keeping a proper hygiene of soft linings. Modifyin...
متن کاملComparison of the Effect of two Denture Cleansers on Tensile bond Strength of a Denture Liner
STATEMENT OF PROBLEM One of the most clinical challenging issues in prosthodontics is debonding of soft liners from the denture base. PURPOSE The aim of this study was to evaluate and compare tensile bond strength between soft liner and heat-cured acrylic resin when immersed in two different types of denture cleanser and distilled water, at different period of times. MATERIALS AND METHOD In...
متن کاملEffect of viscoelastic deformation of soft tissue on stresses in the structures under complete denture.
The time dependency of stress distribution in the supporting structures under dentures was simulated, under three loading conditions, by visco-elastic finite element stress analysis. In this simulation, viscoelastic material, was used as a model for soft tissue. The results indicate that the viscous flow of soft tissue and the loading position are factors determining stress intensity in the sup...
متن کاملA Technique to Guide and Measure the Reduction of a Processed Mandibular Complete Denture for Resilient Soft Liner
A resilient soft liner (RSL) has been used in processed complete dentures but controlling its thickness has always been a challenge because of uneven reduction of the denture’s intaglio surface. Use of a thermoplastic vacuum-formed template and an endodontic K-file, as guides, for the reduction of a processed mandibular complete denture to receive RSL is described in the present report. A proce...
