Evaluation of Dimensional Stability in Four Types of Impression Materials Using Digital Analysis.

ABSTRACT:

Background

Dimensional precision of casts is essential for the quality of fixed prosthesis therapy, with the impression technique being a crucial component affecting this precision. This in vitro study is to evaluate the dimensional precision of casts generated from four varieties of impression materials.

Materials and methods

Utilizing 20 specimens, four types of impression materials were fabricated and subsequently classified into four groups: condensation silicone impression material group (heavy and light body), condensation silicone impression material group (light body only), addition silicone impression material group (heavy and light body), and alginate impression material group. Dimensional stability was evaluated by acquiring imprints of an acrylic mold with three
