- Description: Scanning instead of impression trays, design on screen, milling from a ceramic block: this is how a crown is made digitally.

In the past, a crown meant an impression tray with impression paste, a plaster model and handwork in the laboratory. With CAD/CAM technology, much of this is done digitally – from the scan in the mouth to the milled ceramic. This makes the path to a crown more comfortable and the result very precise.

In short

For a CAD/CAM crown, the prepared tooth is scanned digitally, the crown is designed on the computer and milled from an industrially manufactured ceramic block. Until it is ready, a temporary crown protects the tooth; the crown is fitted at the follow-up appointment. Advantages: no impression tray, a very precise fit and stored data.

## Procedure

Procedure 
1. **Preparation**under anaesthesia: removing decay and old fillings, shaping the tooth.
2. **Scan**[digital impression](https://zahnarztpraxis-st-peter.de/en/guide/digital-dental-impression/) of the tooth, the neighbouring teeth and the opposing jaw.
3. **Temporary crown**protects the tooth until the crown is ready.
4. **Design**The crown is designed on screen and adapted to your bite.
5. **Milling and firing**The crown is made from a ceramic block; glaze and colour are adjusted individually.
6. **Fitting**at the follow-up appointment: checking the fit, bonding it adhesively, checking the bite.

The crown is precisely milled from the ceramic block.

## Advantages of the digital route

- no impression tray – comfortable, especially if you have a gag reflex
- a very precise fit, because scanning and design involve no material distortion
- homogeneous, industrially manufactured ceramic
- stored data – a replacement can be made without a new impression

## When a master dental laboratory is needed

- larger bridges and very complex cases
- particularly high aesthetic demands for individual front teeth (layered ceramic)
- situations in which the gums first need to heal

In these cases we work with a master dental laboratory – the digital impression is simply transferred.

## Frequently asked questions

How many appointments will I need?

Usually two: preparation and scan at the first appointment, fitting of the finished crown at the second.

Is the crown as strong as a laboratory crown?

Industrially manufactured ceramic blocks are very homogeneous and resilient. When used for the right indication, CAD/CAM crowns are long-lasting.
