I recently sat in a Hands-On course with Dr. Peter Harnois. We spent several hours discussing veneers. The primary topic was a discussion of prep design, tooth preparation in order to get the tooth ready to receive a veneer. Specifically, Dr. Harnois discussed Lumineers, which use strong lithium disilicate, and can be as thin as 0.5mm. The bonding of veneers with a resin cement is central to the combined strength as this prevents displacement and prevents flexure of the veneer.
Denmat is the dental lab that is responsible for the Lumineers and minimal prep and/or no-prep veneer options. I was compelled by the results that Dr. Harnois showed off. Here is a virtually no prep case that I completed with a single veneer for a lateral for a patient this past week. Click for FULL SIZE VIEW
