USING OF PROTECTIVE COATING OF THE CONTACT SURFACE OF PLASTIC DENTURES BY USING AN ADHESIVE SYSTEM FOR PREVENTION AND TREATMENT OF HIV-INFECTED PATIENTS WITH INTOLERANCE TO ACRYLIC DENTAL PROSTHESES
The sensitizing effect of prostheses made of acrylic plastics depends on the chemical composition of the dental material and intolerance causes in such cases are often substances released from acrylates, as well as metabolic products of microorganisms. Patients who use removable dentures, due to HIV infection, which is accompanied by severe immunodeficiency, intolerance to acrylates is more pronounced.Using ”Hitachi S 405 A” scanning electron microscopes, the authors studied the contact surfaces of plastic dentures before and after shielding with a silicone, metal coating, and light curing adhesive system” Gluma comford bond” (Kulzer).It was revealed that on the surface of prostheses with silicone and metal coatings, cracks and defects appear over time, which contribute to the penetration of ingredients on the surface of the prosthesis, and also change the color of the base materials. When shielding the contact surface of plate prostheses with an adhesive system, the surface of the prosthesis is covered with a uniform film that retains its properties for a long time, which is one of the effective methods for the prevention and treatment of intolerance to acrylates, especially in patient suffering from HIAIDS.
