Three-dimensional comparison is repeated after storage of impressions for 1 week to re-evaluate the dimensional stability of the impression materials. All the impressions were digitized and compared on eight predetermined points using a 3D compare software by the superimposition of computer-aided design files of impressions onto that of Standard tooth model. Materials and Methodology: Impressions were made of standard tooth model and custom trays using the three monophase impression materials, i.e., Group A–Vinyl polysiloxane (VPS), Group B-Polyether (PE), and Group C-Vinyl Polyether silicone (VPES). The aim was to evaluate and compare the accuracy and dimensional change of elastomeric impression materials with a three-dimensional (3D) approach. There is limited literature available on this combination material. Source of Support: None, Conflict of Interest: NoneĭOI: 10.4103/jdmimsu.jdmimsu_291_20 Abstractīackground: The development of material science has allowed integrating qualities of polyether (PE) and Vinyl Polysiloxane (VPS) into a newer material Vinyl polyether silicone (VPES).
