Hi Mental Dental, Thanks for your videos. I am a Dentist and Ceramist. @1:46 Technically, the opaque porcelain does NOT mask the dark oxide color. Opaque porcelain is a little translucent. Its the opaquer layer that masks the color and later opaque porcelain is applied and fired on to the coping. The layers in PFMs are Metal -> oxidation layer -> wash opaquer -> opaquer -> opaque porcelain (aka opacious porcelain) -> dentin porcelain -> and/or enamel porcelain -> glaze.

Super helpful! Thanks so much, you're the hero we don't deserve lol.


I honestly would love it if you went into even more detail on these options for crown materials. Sorting through all of the information online and in textbooks to learn what we need to know about the options is pretty difficult. That's why your stuff is so great.

Hi Dr. Ryan. What is the most common mistake in veneer preparation? Is it something to do with the angulation of the bevel or just too much reduction of the prep? And if it is because of the reduction of the prep, what location specifically? Thank you in advance.
