Summary

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.

Detailed description

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. Aim and objectives: To evaluate the surface topography and color stability of implant supported provisional restorations fabricated using two different 3D printing materials in mandibular posterior region. Setting: Department of Prosthodontics and Crown \& Bridge, PGIDS Rohtak. Study Design: Randomised clinical trial. Population/Participants: Provisional restoration will be fabricated using two different 3D printing materials. Sample Size: Total of 24 samples will be prepared (n=12 samples per test group). Methodology: This is an in-vivo study and will be carried out in the Department of Prosthodontics and Crown \& Bridge, Post Graduate Institute of Dental Sciences, Rohtak with the purpose to evaluate the surface topography and color stability of implant supported provisional restorations fabricated using two different 3D printing materials in mandibular posterior region. Outcome Measures: Measuring the surface topography using profilometer and color stability using spectrophotometer. Statistical Analysis: Data obtained would be compiled on MS Office Excel Sheet (v 2010) and will be subjected to statistical analysis using statistical package for social sciences (SPSS v 21.0, IBM). Intergroup and intragroup comparisons will be done according to distribution of data.
