“…If the roughness is greater than 0.2 μ m Ra, the denture surfaces can attract plaque and germs. It is the dentist's duty to leave a polished surface on dentures and other acrylic applications (10) . The purpose of this study was to assess how different polishing methods affected the surface roughness of two different denture base materials.…”

Background: Regarding acrylic resin, a direct link was found between surface roughness, plaque buildup, and microbial adhesion. However, the current polyamide material's surface characteristics are still debatable, especially after utilizing conventional polishing and finishing techniques. Heat curing acrylic resin makes it easy to evaluate the surface characteristics of each material and to follow advice for the best practices. Objectives: The aim of the current study is to evaluate and compare the surface Roughness of heat cure acrylic resin and flexible acrylic resin materials before and after different surface treatments. Material and Method: A total of (80) sample were prepared. These samples were divided into two main groups (made from heat cure acrylic resin and flexible acrylic resin). Each group contains (40) samples and were divided into four additional groups according to the surface’s polishing treatment. Each group of material have (10) specimens, the first group was polished with pumice, the second groups were polished with pumice and then glazed, the third group was polished with investment (Phosphate bonded investments) and then glazed, and the fourth group was glazed. A digital surface roughness tester meter (TR: 220) device was used to indicate the values of the roughness of specimens before and after surface polishing treatment. Results: The result of surface roughness of heat cure acrylic resin using t-test analysis revealed that a significance difference among all the study groups (p< 0.05). The result of surface roughness of flexible acrylic resin using t-test analysis revealed that a significance difference was reported between all the study groups (p< 0.05). Conclusion: It was concluded the surfaces roughness was decreased in the control group of (heat cure acrylic resin and flexible acrylic resin materials) when polished with pumice, while it was increased in the experimental groups after polished with glaze material. Compared to pumice and burning investment materials, the polishing material (light cure glaze) is noticeably rougher.

Background: Certain cases such as anterior cross bites require a different aesthetic removable denture technique from the conventional removable denture. Purpose: To provide an overview of a case about the technique of making aesthetic acrylic resin removable partial dentures for anterior tooth replacement in cases of anterior cross bite. Case analysis: The study examined the working model with maxillary and mandibular anterior cross bite cases. Result: The arrangement of artificial teeth was carried out as ideally as possible, so that it became harmonious. In this case, the incisal artificial teeth 11, 12, 21 were brought forward labially, so that an edge-to-edge position was formed with the opposing teeth. The clasp made was a half jackson which was placed on teeth 15 and 25, so that when the patient smiles the clasp is not visible to fulfill the aesthetic requirements. Conclusion: The technique of making aesthetic removable partial dentures in cases of anterior cross bite that has received more attention is the arrangement of the dental elements because it is different from the normal tooth arrangement. The artificial teeth were arranged in edge-to-edge bite position in order to obtain a harmonious occlusion while taking into account of the labial arch of the adjacent tooth as well as occlusion with the opposing tooth.
