Hi,

I finally decided to get my emax veneers with minimal prep - my dentist took impressions of my original teeth made a exocad design of my new teeth and got a 3 model printed of my new teeth

To see how the new teeth will appear in my mouth the dentist used temporary enamel wax like material to transfer the 3d printed model to my teeth and after taking pics and making sure that I was ok with the new shape of my teeth he removed the temporary material from my teeth

Now the next step is to prep my teeth - but he informs me that we need to set the temporary 3d model again on my teeth before prepping them so that my actual teeth are minimally prepped - my common sense tells me that we should not prep after coating them with the temp wax material rather he should prep my naked teeth without coating them with the temporary material

Is there any reason why its better to prep on the teeth coated with the temp material as they will finally appear with the veneers rather than prepping my naked teeth as they are ?

Thanks
