The effect of autoclave processing on some properties of heat cured denture base material
Background: Although most of the physical and mechanical properties of denture base resin polymerized by the conventional heat polymerization have been studied, the effect of autoclave processing in these properties has not been fully determined. The aim of the present study is to investigate the effect of two different cycles of autoclave processing on the transverse strength, impact strength,...
متن کاملEffect of potentially chromogenic beverages on shear bond strength of acrylic denture teeth to heat-polymerized denture base resins
BACKGROUND Detachment of denture acrylic resin artificial teeth from denture base resin is one of the most common problems presented by denture wearers. PURPOSE This study investigated the shear bond strength (SBS) and fracture type of bonding interface of two commercial acrylic teeth (Vipi Dent Plus e Biolux) to two denture base resins (Vipi Cril e Lucitone 550) after immersion in potentiall...
متن کاملSome mechanical properties of a highly cross-linked, microwave-polymerized, injection-molded denture base polymer.
PURPOSE The impact strength and the flexural properties of denture base materials are of importance in predicting their clinical performance upon sudden loading. This study compares the impact and transverse strengths and the flexural modulus of three denture base polymers. MATERIALS AND METHODS The investigation included a relatively new microwave-polymerized polyurethane-based denture mater...
متن کاملeffect of the processing cycle on dimensional changes of heat-polymerized denture base resins
background: the second processing cycle for adding the artificial teeth to heat-polymerized acrylic resin denture bases may result in dimensional changes of the denture bases. the aim of thisstudy was to evaluate the dimensional changes of the heat-polymerized acrylic resin denture bases with one and two-cycle processing methods. materials and methods: a metal edentulous maxillary arch was used...
متن کاملThe effect of mechanical and chemical polishing techniques on the surface roughness of heat-polymerized and visible light-polymerized acrylic denture base resins.
OBJECTIVE The purpose of this study was to compare the effects of mechanical polishing (MP) and chemical polishing (CP) on the average surface roughness (Ra) of heat-cured (HC) and light-cured (LC) denture base acrylic resins. METHODS A total of 120 specimens (30 × 15 × 3 mm) were prepared from one HC and one LC acrylic resin. To remove nodules and gross surface irregularities, all specimens ...
