The purpose of this article was to review the biocompatibility, physical, and mechanical properties of the polyamide denture base materials. An electronic search of scientific papers from 1990-2014 was carried out using PubMed, Scopus and Wiley Inter Science engines using the search terms "nylon denture base" and "polyamide denture base". Searching the key words yielded a total of 82 articles. ...

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...

Background: Heat cured acrylic resin is the most widely used material in the manufacture ofdenture base, but has mechanical properties weakness (transversal strength and impact strength). Alternative to increase the mechanical properties of acrylic resin is the utilization of reinforcing fibre that is polyethylene fibre that has advantage such as good aesthetic, easy to manipulate and increase ...

The incorporation of computer-aided design/computer-aided manufacturing (CAD/CAM) technology into complete denture fabrication brings about several advantages to the fabrication process, providing better predictability of the desired outcomes and high accuracy of denture fit, mainly because the milling of prepolymerized acrylic resin eliminates the shrinkage of the acrylic base. Also, there is ...

Excess denture movement during function may cause to jeopardize the resorption of the residual ridges and the mechanical trauma on the abutments in the partially dentate mouth. A removable partial denture (R.P.D.'s) should be so constructed that the artificial teeth on the denture base will be stabilized in their spatial position by way of the compensatory support due to the remaining abutments...

Harold Vernon first introduced acrylic polymers as denture base materials in 1937. A survey showed that 33% of denture repairs were to restore debonded teeth.1 Factors that affect the bonding of acrylic resin teeth to the denture base are dewaxing procedures, residual wax on ridge laps of teeth,2 and careless application separating media like sodium alginate to the teeth, leading to contaminati...

background: debonding of denture teeth from denture bases is the most common failure in removable dentures. the purpose of this study was to evaluate the effect of surface treatments on shear bond strength of denture teeth to heat-polymerized and autopolymerized denture base resins. materials and methods: in this experimental in vitro study, 60 maxillary central incisor acrylic teeth were divid...

Crossliked plastic denture teeth have been used clinicaly in order to improve the poor wear resistance of conventional acrylic denture teeth. We suggest that highly crosslinked denture teeth are possibly disadvantaged compared with conventional ones, when considering the adhesion to denture base and impact resistance. The purpose of this study is to evaluate the impact resistance of crosslinked...

BACKGROUND Denture repair involves joining two parts of a fractured denture with a denture repair material. Hence, a substantial repairing system for denture base fracture should be there to elude frequent fracture. MATERIALS AND METHODS Surface treatment of conventional heat cure denture base resin with different surface treatments (chemical ethyl acetate, and mechanical roughening with bur)...

objective: studies have demonstrates that physical properties of denture base affect patient satisfaction and acceptance. thermal conductivity is among the most important properties of denture base influencing the sense of taste and gingival health. the conventionally used acrylic resin has a low coefficient of thermal conductivity. this study aimed to improve the thermal conductivity of acryli...
