The aim of this study was to compare the bond strength between acrylic denture base and teeth subjected to 6 surface treatments. Ninety-six specimens were made with poly(methylmethacrylate) teeth bonded to a microwave-polymerized acrylic denture base material. The specimens were distributed into 6 groups (n=16) according to surface treatments: CT - no treatment (control); MN - methylmethacrylate monomer etching; AO - 50-µm-particle aluminum oxide air abrasion; BR - glaze removal with a round bur; ST - surface grinding with an aluminum oxide abrasive stone; group CV - cavity preparation (diatorics). The control and surface-treated groups were subjected to a compressive load at 45º angle to the long axis of the teeth. Data were analyzed by one-way ANOVA, followed by Scheffé's test (p<0.05). Bond strength means and (SD) in kgf for groups were: CT: 18.19 (7.14), MN: 18.34 (5.28), AO: 23.82 (5.40), BR: 23.30 (4.79), ST: 25.39 (7.80) and CV: 17.48 (7.17). There was statistically significant difference (p=0.037997) only between ST and CV. In conclusion, ridge lap surface grinding with an aluminum oxide abrasive stone provided the highest bond strength, though it differed significantly only when compared to diatorics. The other surface treatments provided similar bond between the acrylic denture base and teeth.

Abstract Aim Debonding of denture teeth from the denture base can be frustrating for both the clinician as well as his or her patients. The wear resistance of composite denture teeth has been well investigated since their introduction, but there have been few studies about the bonding of these teeth to acrylic denture base resins. The aim of this study was to compare the bond strengths of two brands of acrylic and one brand of multilithic denture teeth to acrylic denture base material. Methods and Materials In this experimental-laboratory study, three types of denture teeth—Yaghoot, Super Brilian, and Major—were used. After grinding the glossy ridge lap surfaces, the teeth were mounted on two sides of triangularshaped wax models. Then the wax elimination and resin processing laboratory procedures were carried out as is done with the fabrication of a complete denture. Each of the specimens was tested using a universal testing machine with a cross head speed of 5mm/min at an angle of 130 degrees to the long axis of the teeth. The data were analyzed using one-way ANOVA and Chisquare tests. Results The mean bond strength in the Yaghoot group was 717.43±293.59 N while in the Super Brilian group it was 578.40±395.38 and in the Major group, 547.95±296.75N. However, there was no significant difference between the three groups (p=0.194). Conclusion Although the mean bond strength in the multilithic group was higher than in the other groups, no significant difference was found between the three groups. There was no significant difference between the three groups with regard to the prevalence and type of fracture site. Clinical Significance The bonding strength of multilithic denture teeth to denture base resins was found to be comparable to, and even slightly higher than, acrylic conventional denture teeth, making them a promising choice for clinicians in the fabrication of removable dentures.

Debonding of denture teeth from the denture base has posed a great problem to the clinician and patient. Chemical and mechanical treatments have been performed separately, but there are no studies performed using the combination of chemical and mechanical surface treatments. This study aims at evaluating and comparing the bond strength by using chemical and mechanical surface treatments.60 maxillary right central incisor teeth were used in 5 groups for surface treatment on the ridge lap area: 1 untreated, 2-sandblasting, group 3- Heat cure monomer, 4- sandblasting+ monomer, 5- Dichloromethane. The acrylic teeth were attached to a wax block at an angle of 45º. These were flasked and dewaxed, followed by surface treatment and acrylisation. All cured specimens were loaded under a universal testing machine on the palatal surface at a cross head speed of 1mm/min till fracture occurred. Data obtained was statistically evaluated by one way ANOVA. Surface treatment with dichloromethane showed the highest bond strength of acrylic teeth to heat cure denture base when compared with sandblasting and monomer application. On visual analysis of the fractured specimens, maximum amount of cohesive failures were noticed in the dichloromethane group.Dicholoromethane can be used as an effective and quick method to improve the bonding of acrylic teeth to denture base.
