What is an advantage of using addition silicone over other impression materials?

Using addition silicone as an impression material has several advantages, among which its superior tear resistance is a significant one. Tear resistance is crucial in impression materials because they need to withstand the stresses that occur during the removal process from the mouth, especially in areas with undercuts. Addition silicone demonstrates excellent dimensional stability and has a high resistance to tearing, which helps ensure that the final impression is accurate and detailed without compromising the shape during handling.

While other materials might have certain benefits, they typically do not match the tear resistance found in addition silicone. This property contributes to the overall quality of the impressions taken, making them suitable for precise dental applications, including the fabrication of crowns, bridges, and other prosthetic devices. The combination of tear resistance with its hydrophilicity allows addition silicone to capture intricate details in the oral cavity effectively, enhancing the overall performance in restorative dentistry.
