The impression is best taken at the initial consultation. If, at the consultation, the patient is unsure as to which treatment option to take, we recommend taking a “no obligation quick impression” to prevent the patient having to return.
For a usable impression, please ensure the following: • The patient’s teeth must be in centric occlusion. • Include teeth on either side of the treatment tooth. • Canines should be in the impression as our lab needs canine-guidance to get the occlusion correct. • The entire crown of the tooth to be treated should be in the impression. Less impression material is required for the opposing arch as only the occlusal surfaces are required.
Material choice Any silicone impression material is suitable. We recommend fast set PVS materials such as bite impression materials. Cavex ColorChange Alginate is also acceptable as this is dimensionally stable for 7-9 days. If you are concerned about the longevity of alginate, please cast the treatment side with stone-plaster. Wrap in damp tissue and place in a Ziplock bag. Wrap impressions carefully in bubble-wrap to minimise the chance of distortion during shipping to the lab.
