Let’s see what a dental mechanic does in order we had beautiful smiles.
All-cast crown from stainless steel.
Each tooth has its number. This one is 46th. The main technological stages are:
1. Making of a plaster model.
2. Modelling of a tooth.
3. Metal casting.
4. Processing and adjustment of a crown.
Low jaw imprint
A dental mechanic turns imprints into real models. Making a split cast is the most difficult in this work.
Drilling a plastic socket with a laser.
Inserting pins, pouring the imprint with plaster and covering it with the socket.
The plaster has dried out and the imprint can be removed.
Turning of a dental arch
And cutting it into separate segments
In this particular case we cut it into 5 segments. Then the tooth demanding the crown must be turned. Excess plaster below the arrow must be removed.
They use special lacquer that serves as cement.
