Porcelain Veneer Cementation step by step technique

[@Farahnoga]

Is the ultrasonic bath necessary?

[@harhoor2006]

why orthophosphoric acid on already etched porcelain surfuce !!!!

[@drabyad2498]

After hydrofluoric acid etching of the ceramic a layer of salts develops on the surface which acts as a barrier preventing good priming of the surface. Phosphoric acid is thought to remove these salts and dissolve them for a fresh surface. (However this is an arguable matter and some argue against its use)

[@c_lent]

@@drabyad2498 the phosphate groups in the phosphoric acid fight to bind with the phosphate groups in the cement less adhesion to the crown/tooth interface. Not recommended anymore

Can i use this silane in the attached photo from 3M 3M™ Silane Coupling Agent, 68300

[@romerodentalseminars]

Yes you can.

What container is used to carry the veneer when place in ultrasonic bath

[@romerodentalseminars]

Elenza Jacob plastic container

[@SmilesByDesignAdmin]

is the cement light cure or dual cure?

Are u washing silane with water??

Logically No !

What about applying bonding ,cement and veneers and cure it at the same time ,don’t you think it’s better?

[@dr.davident]

Why?

[@user-hd3hy4co1h]

@@dr.davident actually I need to know if it’s ok or we will face problems later ,there is a theory says do one step curing (bonding ,cement and veneers) so we will not lose the fitting

[@sherafati]

​@@user-hd3hy4co1h You can not ensure that you get a proper hybrid layer if you co-cure. You need to cure the bonding agent on tooth surface separately to make sure you get a good hybrid layer. As for sitting issues, you need to completely air thin the bonding agent.

Although the ceramic material is brittle material ,but we can use it in less than 1mm for facial and occlusal veneer ..why??

[@emyfekry3344]

Porcelain is brittle like natural tooth but porcelain is so hard to withstand chips and cracking although wrong or heavy frequent compact forces could cause fracture by the way. So it's indicated as veeners or full crowns just for anterior teeth where no heavy forces might be applied on likewise posterior teeth

[@nutellaluis683]

@@emyfekry3344 can it br used for 2 or more units bridge for the anteriors or just for individual crown?

[@louisbarros9757]

Quick question Mario, what do you think about curing the bond prior to cement application? Does it make any difference? I see you cure everything all at once, does this give better results? Thanks for sharing!

[@romerodentalseminars]

Louis Barros I cure the adhesive layer prior to bonding the restoration. For me it is critical to have a fully polimerized hybrid layer and curing all at once can create some problems if it does not reach the adhesive layer with the needed energy.

@@romerodentalseminars did you cure the bond on the intaglio surface of the veneer before applying the cement?

[@romerodentalseminars]

@@puneetsekhon3436 No, you should not cure.

[@puneetsekhon3436]

@@romerodentalseminars thanks for the prompt reply, appreciate it. What is the reason behind not curing it before the cement?

[@romerodentalseminars]

@@puneetsekhon3436 the use on bonding agent in the intaglio surface is only to improve “wetability” of the resin cement to the silanated glass surface.

[@dr.davident]

Ultrasonic not ultrasound ! and thanks for the amazing video :)

[@romerodentalseminars]

Thanks for catching the typo. We will correct it.
