Rigid Impression Materials

Rigid impression materials are used in dentistry to create accurate molds of teeth and gums. They are firm and inflexible once set, which helps produce detailed and stable impressions for making crowns, bridges, or dentures. These materials are typically used when a very precise, durable mold is required, and they are ideal for capturing fine details of hard structures like teeth. Examples include materials like stone or plaster. Their rigidity ensures that the impression holds its shape during handling and casting, resulting in accurate restorations that fit well.
