Dental impression materials are used to copy oral tissues, create a dental impression, and then pour gypsum into them to produce a dental cast.
Polysulphide Impression Material, a type of non-aqueous elastomeric impression material, was developed to overcome the limitations of hydrocolloids, offering both dimensional stability and elasticity. Definition of Polysulphide: Polysulphide is an elastic impression material characterized by an SH group-terminated polymer. The…
Definition of Alginate: Alginate, recognized as an irreversible hydrocolloid, constitutes colloid particles comprising alginic salt polymers. Through a chemical reaction, it transitions from a sol (liquid) to a gel (solid) state, resulting in the irreversible nature of the set impression.…
AGAR IMPRESSION MATERIAL is a reversible hydrocolloid composed of agar weed polymer chains. These polymer chains align to form fibrils, which trap water in the interstices between the chains. This conversion from sol to gel is a thermal process, making…
Definition of Zinc Oxide Impression Material QZN: Is zoe mucostatic or mucocompressive? Zinc oxide impression material is a paste-based substance composed primarily of metallic oxides. It possesses excellent flow characteristics, allowing it to capture intricate details of oral structures accurately.…
Introduction Impression compound is a dental material used for recording impressions of oral tissues in various clinical procedures. How are the impression compounds classified/ Types of impression compounds used in dentistry It is classified into two main categories based on…
Definition of Impression Materials Impression materials in dentistry refers to substances used to create precise negative replicas of oral soft and hard tissues. These replicas, known as impressions, capture the detailed morphology of the patient’s mouth, including teeth, gums, and…
