Do you really know them? Veneer vs Non- Prep Veneer


Veneers were invented by California dentist Charles Pincus in 1928 to be used for a film shoot for temporarily changing the appearance of actors’ teeth. Later, in 1937 he fabricated acrylic veneers to be retained by denture adhesive, which were only cemented temporarily because there was very little adhesion. The introduction of etching in 1959 by Dr. Michael Buonocore aimed to follow a line of investigation of bonding porcelain veneers to etched enamel. Research in 1982 by Simonsen and Calamia revealed that porcelain could be etched with hydrofluoric acid, and bond strengths could be achieved between composite resins and porcelain that were predicted to be able to hold porcelain veneers on to the surface of a tooth permanently. This was confirmed by Calamia in an article describing a technique for fabrication, and placement of Etched Bonded Porcelain Veneers using a refractory model technique and Horn describing a platinum foil technique for veneer fabrication. Additional articles have proven the long-term reliability of this technique.


No Prep Veneer: 0.3mm
Conventional Veneer: They are made for moderately prepared teeth, which range from about 0.3 mm in some tooth locations to about 1.0 mm on the incisal or occlusal edges

What if Crown + Veneer Case 

We did come across esthetic cases crown and veneer for anteriors 

Advice for chairside, always remember the thickness of veneer cannot cover much dark stump, you have to let the technician knows LT (low translucent) ingot for EMAX, PLUS when you cement you have to use shade adhesive balance the shade.

For shade matching, if the patient has a dark stump always choose 2 shades lighter than the shade match, in order to neutralise the final color. 

*** shade match picture must be taken and send in order to get the best result. 


The keys of keeping the duration is when you do the insertion,  the isolation of moisture is determined the life of the Porcelain Veneer.
