Frictional behavior and surface failure of acrylic denture teeth.
نویسندگان
چکیده
The water characteristics of acrylic denture teeth were investigated under single- and double-pass sliding. The response of acrylic teeth to sliding was that of a relatively ductile material. The wear characteristics were affected similarly by environments of water and saliva. The "enamel" surfaces showed more resistance to penetration and were less susceptible to surface damage than the "dentin" surfaces. The effect of the second pass was to increase track width and cause a more severe mode of surface failure.

Effect of Mechanical Modification of Acrylic Resin Denture Teeth Bonded to Acrylic Denture Base
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 ...

Background and Aims: Debonding of denture teeth from the denture base can be frustrating for both clinician as well as patient. The aim of this study was to determine the effect of different tooth preparations on the tensile bond strength of composite denture teeth to acrylic denture base material. Materials and Methods : In this experimental study, 108 anterior Glamour teeth were selected ...
متن کاملمقایسه استحکام باند دندان‌های کامپوزیتی و آکریلی به آکریل‌های بیس دنچر گرماپخت و خود به خود پلیمریزه شونده
Background and Aims: Failure of bonding between artificial teeth and denture base material is a considerable problem for patients who wear dentures. Because of the cost of denture repair and the expensive price of foreign artificial teeth, this study was designed to compare the bond strength of composite and acrylic artificial teeth with heat-cured and auto-polymerized denture base resins.Mater...
متن کاملEvaluation of Bond Strength of Acrylic Teeth to Denture Base using Different Polymerization Techniques: A Comparative Study
BACKGROUND Acrylic teeth have long been used in the treatment of a complete denture. One of the primary advantages of acrylic teeth is their ability to adhesively bond to the denture base resins. Although the bonding seems satisfactory, however, bond failures at the acrylic teeth and denture base resin interface are still a common clinical problem in prosthodontics. The purpose of this study wa...
متن کاملComparative Evaluation of Bond Strength of Surface-treated and Surface-modified Anterior Acrylic Teeth
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...
