简要总结
Patient attending the Outdoor Patient Department of the Department of Prosthodontics at Post Graduate Institute of Dental Sciences, Rohtak will be screened. The screening will include history taking and clinical examination of the partially edentulous patients. Patients will be selected according to the inclusion and exclusion criteria. Single stage endosseous implants will be placed. Two different Biocompatible 3D printed Polymethyl methacrylate resin will constitute two groups, Group A and Group B. 3D printed provisional poly methyl methacrylate resin crowns will be fabricated with Group- A and Group-B material followed by evaluation of surface topography and color stability after intraoral use.
详细描述
Title: "Comparative Evaluation of Surface Topography and Color Stability of Implant Supported Provisional Restorations Fabricated using Two Different 3D Printing Materials in Mandibular Posterior Region: A Randomized Clinical Trial".
Rationale: The study needs to verify the surface topography and color stability of implant supported provisional restorations fabricated using two different 3D printing materials in mandibular posterior region.
