One of the things that changed my career was when I started collecting a few real teeth.
I went to dentists and especially a denture clinic and requested some of their extractions for study purposes. Aot of them still had blood and tissue on them so I put them in chlorox and in the ultrasonic untill the tissue desolved.
Probably 5 to 10 min. If you leave them in too long it will start to pit the enamel.
Natural teeth have to be kept hydrated or they will lose their transulcancy. This starts happening immediately so I keep them stored in old porc. bottles in water. This is why I always request for shade checks to be done before preparation of on a later day.
I had spent all my time studing pictures of teeth or other peoples crowns.
One of the first things I noticed when I got real teeth in my hands, is that my crowns looked terrible. I spent so much time on them but sometimes they looked more like flowers or little castles.
I put the teeth on my porc bench and used them as I stacked and contoured porc. crns.
Id encourage everyone to do the same, it will change the way you look at your craft.
Can you quess which is the real deal and which is the fake????
This is Willceram porc. It has been discontinued and replaced with Inline.
But I used to love using it.
Here is a close up of the real tooth. Isnt it beautiful!!!
Look at the design of it. Look at the detail in the lobes and the color.
When you compare the crn with the real thing up close, there is no comparison. It would take high magnification and a tiny bur to get that detail and an explorer to apply the stain and many firings and a hand polish to match the glaze.
I have way too much white on the lingual occlusal, but it is porc not stain so I think I will leave it for now. I dont know if I remember the firing temps for that porc.
