Comparative Evaluation of the Marginal Adaptation of Emax Ceramic Inlays Fabricated Using Traditional Rubber Base and Digital Impression Technique in Permanent Premolar: An In Vitro Study

gag reflex, and the taste of the impression material can also contribute to the negative experience. 6Among the different types of elastomeric material, additional silicones have superior IntroductIonAccurate impression technique is the key factor determining the success of dental prostheses.In the field of dentistry, the traditional approach of using elastomeric impression material and fabricating a stone model has been practiced for ages. 1 Irreversible hydrocolloids and elastomeric materials are commonly used for conventional impressions, offering satisfactory precision and stability in obtaining high-quality impressions. 2However, these techniques can be affected by the operator's expertise and proficiency, and there are inherent errors associated with both the impression material and the technique itself. 3n elastomeric impression material, the most common disadvantages are polymerization shrinkage, release of byproducts due to chemical reactions, and incomplete elastic recovery. 4The absence of a standardized impression-taking procedure, along with the deformation of the impression, can significantly impact the overall quality of the restoration. 5dditionally, the conventional technique is frequently reported to be uncomfortable and unpleasant for patients, often inducing
