The heat cure denture base resins are extensively used for their excellent properties such as ease of handling, polishing and esthetics etc. However, the mechanical strength is not sufficient to maintain the longevity of denture. The fracture of acrylic resin denture is a common clinical occurrence. The ultimate goal of denture repair is to restore the denture''s original strength and avoid further fracture. Satisfactory repairs must be easily and rapidly completed, match the original color of the material and maintain the dimensional accuracy. The objectives of the study are to evaluate the transverse strength and to estimate impact resistant of denture base acrylic resin repaired by different methods having different joint surface contours, and compares it with denture base acrylic resin repaired by conventional method. The work is useful for anybody and everybody who fabricates and repairs dentures. It promises meaningful information to dental undergraduates in clinics, interns, general dental practitioners, lab technicians, post-graduates and research scholars. It will be helpful to both dental academicians and clinicians.
