Condensed silicone, polyvinylsiloxane and polyether impression materials are used in dental implant application. The key feature in impressionmaterials is the surface energy and the second feature is the habit. Substances with a high surface energy and narrow wetting angle get in contact with water. In this case, it determines the material’s contact with the oral tissues and plaster. On the other hand, the habit defines the adaptability of the impressionand the pressure control in case of oral application.
