Description

Impression materials are specially formulated substances used in dentistry and medical procedures to create a precise negative replica (impression) of oral tissues, teeth, or anatomical structures. These impressions are used to produce accurate models, casts, or prostheses for diagnosis, treatment planning, and fabrication of dental restorations and appliances.

They are designed to capture fine surface details, set within a controlled time, and maintain dimensional stability to ensure accuracy.

Common Types Include:
Alginate (irreversible hydrocolloid)
Elastomeric materials (silicone, polyether)
Agar (reversible hydrocolloid)

Applications:
Crowns, bridges, and dentures
Orthodontic and prosthodontic procedures
