If you are not too lucky you’ve been at the dentist’s and maybe you already have a ceramic crown with metal in your mouth, or some of them. But hardly you know what happens outside the dentist’s room and how they make these crowns. Now you have a chance to find it out.
So they get a dental model from a dentist and start the process…
They make a model of a patient’s mouth from various types of plaster.
After opening they get exact copies of the patient’s teeth
In this particular case they plan to make two central cutting teeth.
They apply some layers of special varnish and start making wax moulds for casting.
This is a waxmelter, thickness of the wax shouldn’t exceed 0,3 mm and shouldn’t be thinner as well.
Making the neck thinner with the wax
Then they send it for casting
When the molding is ready, tested, defatted, covered with the first layer of priming, the crowns are sent to a vacuum stove for burning.
The second layer of priming and back to the stove
Metal packs after 2 layers of the priming
Choosing suitable ceramic masses and making necessary consistence
With a brush they start a magic process
And to the stove again
The result of the first burning of the dentin, the mass has subsided for about 10-15% as it was expected.
Applying more layers and making more burnings
Correcting the shape for the last time and applying a very thin layer of special transparent mass.
Final glossy burning
