Bonding of acrylic denture teeth to MMA/PMMA and light-curing denture base materials: The role of conditioning liquids

Effect of potentially chromogenic beverages on shear bond strength of acrylic denture teeth to heat-polymerized denture base resins

“…Although studies that evaluated bond strength of acrylic teeth and base resins after prolonged immersion in water or after thermal cycling are found in the literature,[212223] there are no researches on the effects of immersion in staining beverages on bonded interface. Thus, this study aimed to evaluate the shear bond strength (SBS) of two commercial acrylic teeth and two commercial brands of denture base heat-cured resin after immersion in three potentially chromogenic beverages.…”

Effect of different adhesives combined with two resin composite cements on shear bond strength to polymeric CAD/CAM materials

“…Cleaning and air-abrasion of the denture teeth leads to micro retention and results in higher bond strength to the denture bases 12) . Also, the application of additional adhesives increases the bond strength between the polymeric teeth and the denture base material 13,14) . Creating durable bond strength between the restorative material and the tooth is crucial for the long-term reliability of a restoration and therefore its success.…”

Effects of Different Surface Treatments on the Bond Strength of Acrylic Denture Teeth to Polymethylmethacrylate Denture Base Material

“…2,3 The causes are related to several factors including remaining wax on the ridge lap area of the teeth because of incomplete elimination or contamination with tin-foil substitutes, 4 careless application of the separating medium or insufficient available monomer during processing, the polymerization method used in the processing of denture base resins, 3 or force overload during the time in service. 5 According to Cunningham and Benington, 6 prior to the application of a suitable denture base resin, complete wax elimination of the bonding surface is the most important step for high denture tooth bond strength. Furthermore, the presence of impurity was found to lower the stress threshold for cracks to propagate, thus increasing the risk of tooth debonding.…”

“…2 A reliable bond between a denture tooth and a denture base material could be constructed with the contribution of an interpenetrating network (IPN) or a covalent bond, macromechanical retentions, and micromechanical retentions. 5 Several attempts have been made by researchers to enhance bond strength between acrylic resin teeth and denture base materials. Mechanical preparation of the tooth surface 7-11 etching it with chemicals, [12][13][14][15] or wetting it with organic solvents 16,17 were performed to obtain reliable bond strength.…”

“…In addition, an IPN or a covalent bond were established by grinding and then wetting the surface of the denture tooth with methylmethacrylate (MMA) monomer. 5 Moreover, the surface of the PMMA can be altered by airborne-particle abrasion [18][19][20][21][22][23][24] and laser irradiation. 18,22,25,26 Nevertheless, conflicting results with the use of chemical solvents and mechanical preparation were seen in the literature.…”
