The Desirable Impression Material and Technique Used For partial Dentures among Prosthodontist

Impression materials are used to record intraoral structures for the fabrication of definitive restorations. Accurate impressions are necessary for construction of any dental prosthesis. The relationship between static and mobile oral structures must be reproduced accurately for an optimum cast. Making a cast in gypsum materials from an impression of dental anatomy aids dentists in designing and constructing removable and fixed prostheses. The accuracy of these final restorations depends greatly on the impression materials and techniques. This study aims to identify the type of materials and the methods used by Prosthodontist in their clinics to construct conventional partial dentures and to specify the type and design for removable partial dentures (RPDs); and to then compare them with those taught in dental schools. In conclusion, the polyvinyls and polyethers are more stable to deformation after setting has occurred. All have specific protocols for disinfecting that must be followed to prevent distortion of the material before pouring casts; however, the polyvinyls seem to be most impervious to different disinfection protocols.
