Good photog raph s a re e ssent ia l in communicating with your lab with regards to shade and appearance as well as communicating with the patient. Stage 2 Once the smile was confirmed the famous "Gurel" technique was followed by 'prepping' through the temporaries to ensure that the most minimal approach could be taken to protect the natural tooth structure. Since the teeth had already been prepped, minimal modifications were made mainly around polishing and removing old cement and some caries. Immediate dentine sealing was performed again as per "Gurel" (his book "The Science and Art of Porcelain Veneers" really is a must read and an essential text in my opinion). A double layer cord technique was then used and a 2 stage silicone impression taken to ensure crisp margins. Again a scanner could also be used if the dentist wished. The planned occlusal adjustments were also made at this stage.

This ensured a dry field and the 'temporaries' were removed and the teeth air abraded to ensure the best possible bonding surface. Try in pastes from the Variolink Veneer bonding system from Ivoclar were utilised to check fit and contacts. Once the cement shade had been decided on, the veneers were cemented and cured according to the manufacturer's instructions. I choose to spot cure just the centre of the veneer initially to hold them steady and then floss can easily be passed interpoximal and a 12c scalpel run over the margins gently to easily remove any excess cement.
