EVALUATION OF THE TRANSFER STRENGTH OF ORTHO-ACRYL AS A REPAIR MATERIAL FOR ACRYLIC DENTURE BASE

Background: A significant clinical concern is the acrylic resin dental plate basis fracture, which is a key prosthetic issue for both patients and dentists. Commonly, dentists repair denture base fractures using a repair material that has distinct properties. Obective:The purpose of this paper is to investigate the transverse durability of heated-cure acrylic resin under repairing via auto-polymerizing acrylic resinous viscous substance and Ortho-acrylic resin materials. Materials and Methods: Thirty transverse bond strength test specimens were prepared and fell into three groupings counting on the type of repair material used. The control group consisted of intact heated-cure acrylic resin samples made for testing. The Ortho-acrylic specimen group, on the other hand, was created using a doughing technique and cured using water under air pressure and continual heating with Ivomat. While Group 3, repairs were conducted using auto-polymerizing acrylic resin. The three-point bending transverse strength test was made using an Instron Universal. Results: The controlling group (heat) uncovered a greater mean value in comparison to the other groupings; yet, the cold group demonstrated the least value of transverse bond durability. The variance among all groups is uniform, and the one-way ANOVA indicates that the significance value is more than 0.05. Conclusion:The minimum transverse durability for the heat-polymerized acrylic resin dental plate basis materials ought to be at least 65 MPa. The current work found that the control and Ortho-acrylic groups exhibited transverse strengths above 65 MPa. In this investigation, the Ortho-acrylic repair materials were applied by first layering a powder, followed by a layer of fluid, using gentle pendulum movements. This approach has the potential to lengthen the time it takes for the monomer to spread and cover the repaired surface, which may improve the transverse durability of the substance
