Surface Topography and Color Stability of Implant Supported 3D Printed Provisional Restorations

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.
