Abstract
Objectives: To evaluate and compare the accuracy of four different impression materials utilized as final impressions taken in mandibular edentulous cases, employing the Photo analysis technique.
Materials and Methods: Ten patients were selected, with completely edentulous arches. For each patient, four different impressions mandibular impressions were obtained using four different impression materials namely, 1. Zn/O Eugenol, 2. Putty and Light PVS Rubber Base, 3. Silginat 4. Monophase. All four impressions were boxed, and all were poured using type IV dental stone. Casts were then photographed using a digital camera with fixed, repeatable specifications, and digital photographs were then introduced into computer software (Digimizer® Software V. 4.3.1). Two measurements were taken for each cast and compared.
Conclusions: Zn/O and Eugenol have always been considered the most accurate final impression material utilized in edentulous cases. This study revealed that the more recent, Rubber Base, Silginat, and Monophase impression materials proved to possess equivalent accuracy measured by the Photoanalysis method.
