Dental impression materials refer to a class of substances used by dental professionals to capture an accurate mold or replica of a patient's teeth and other oral structures. These materials are utilized during various dental procedures such as the creation of crowns, bridges, dentures, and braces, as well as in orthodontic treatments.
Typically, dental impressions are made in order to fabricate dental restorations that fit precisely and comfortably within a patient's mouth. They are also crucial for creating appliances that aid in the alignment and correction of teeth. Dental impression materials act as a medium to capture the oral structures in precise detail, ensuring an accurate replica of the patient's teeth.
Impression materials commonly used in dentistry can be classified into two broad categories: elastic and non-elastic. Elastic impression materials, such as dental alginate and polyvinyl siloxane (PVS), are advantageous for capturing fine details and intricate areas of the oral cavity. On the other hand, non-elastic materials like dental plaster are primarily used for study models or for fabricating non-functional prostheses.
Accuracy, stability, and ease of use are significant attributes that dental impression materials must possess. Additionally, these materials should possess adequate flow properties to ensure complete coverage of the tooth surface and capture precise anatomical details.
In summary, dental impression materials are substances utilized by dentists to create replicas of a patient's teeth and other oral structures. These materials are an essential aspect of numerous dental procedures and play a vital role in the accurate fabrication of dental restorations and appliances.
