Communication: A case where the hard/soft acid/base principle holds regardless of acid/base strength
The purpose of this study is to compare the shear bond strength of different resin bases and artificial teeth made of ceramic or acrylic resin materials and whether tooth-base interface may be treated with aluminium oxide sandblasting. Experimental measurements were carried on 80 specimens consisting of a cylinder of acrylic resin into which a single tooth is inserted. An ad hoc metallic frame ...
This study compared the microleakages and compressive strengths of various base materials.<br/>To evaluate microleakages, 50 extracted permanent premolars were prepared. The teeth divided into 5 groups 10 each according to materials. Cavities with a 5.0 mm width, 3.0 length, depth formed on buccal surfaces teeth. After filling cavities different materials, composite resin was used for fin...
Although different commercial brands of artificial teeth are available in the market, debonding from the denture base is still an issue when rehabilitating edentulous patients with conventional or implant-supported complete dentures. The purpose of this study was to investigate the effect of surface treatments on the bond strength of four artificial teeth brands to a denture base material polym...
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...
