Picture material of step-by-step fabrication of e.max crowns aka how crowns are made by a dental technician.
1. Waxing – visualisation of patient’s future teeth on a plaster model.
2. Model – a model prepared by a technician for modelling crowns.
3. Modelled crowns – modelled crowns made of wax before fitting channels.
4. Before insertion – To get ceramic crowns from wax crowns, one has to fit channels (blue objects on the picture) on the modelled crowns.
5. Insertion cone – Wax crowns are placed in a special cone, this is covered with a fireproof material, and afterwards it goes to a preheating furnace, where wax is burnt out.
6. Ready-made pressed crowns – Wax crowns have become e.max all-ceramic crowns in a pressing furnace.
7. Pressed crowns on a model – Ready pressed all-ceramic crowns are placed on a plaster model (side contacts and preparation margins checked).
8. Before glazing – this is how the teeth look like
before giving them gloss and colour.
9. Glazed/coloured crowns on a model – After achieving a suitable colour and high gloss, this is how the ready-made crowns look like on a model.
10. Crowns in the mouth – Dentist cements the teeth on dental cores permanently and the person can smile again.
