- Abstract
The detachment of acrylic resin teeth from denture base is a frequent occurence. The present study is an attempt to determine if retention grooves (horizontal and vertical) of various shapes would improve the tooth-denture base bonding. Methods : The study was conducted on 180 acrylic resin teeth (Maxillary Central incisors, Lateral incisors, Canines) and heat cure denture base acrylic resin. The teeth were mechanically prepared and divided into groups, according to the types of grooves. In the control group, no grooves were prepared. Rectangular shaped test specimens were prepared and tested in Universal Testing Machine by applying force at 130° to the long axis of each tooth, 3mm from the incisal edge at a crosshead speed of 5 mm/min. The data obtained was statistically analyzed by ANOVA and POST HOC tests. Results: Shear compressive bond strength of specimens with vertical retention grooves (inverted cone) was greater (31.94 + 8.75 kg) than vertical grooves (straight fissure) (30.28 + 8.98 kg), horizontal grooves (inverted cone) (23.22 + 8.30 kg), horizontal grooves (straight fissure) (21.72 + 8.08 kg) and the control group (13.36 + 5.58 kg).
