Although impressions provide the foundation for creating highly esthetic and functional restorations, capturing the complete and precise details of the hard and soft tissues surrounding the affect tooth or teeth can sometimes be challenging. As a blueprint for restorative treatments, taking accurate impressions requires the ideal combination of technique and materials to create a durable, physical replica of the patient’s intraoral condition. Many techniques require extensive steps and can be time consuming to learn and perform.
Additionally, shortcomings inherent to the impression techniques and materials themselves can also complicate the impression taking process. Voids and bubbles introduced into the impression material during application can decrease accuracy and durability. Runny materials can increase patient discomfort and inhibit a dental professional from achieving the desired accuracy. Weak impression materials and those that demonstrate poor dimensional stability can contribute to problems when pouring molds or in the laboratory during the fabrication process, ultimately leading to the worst-case scenarios of retaking impressions and/or remaking restorations.
To overcome these challenges, dental product manufacturers have developed and introduced alternative impression materials and techniques that demonstrate user-friendly and predictable characteristics. As a result, it is now easier for dental teams to effectively capture the details of the preparation and surrounding dentition. In particular, enhanced wash and putty materials demonstrate increased tear strength and durability, ensuring greater stability and repeated impression use. [Read more…]
