PFM (Porcelain Fused to Metal)

PFM crowns and bridges can look very natural. It depends a lot on good cooperation between the dental lab and the dentist’s office. Although all around the world, PFM are gradually being replaced by full-ceramic. 



Disadvantages of PFM

1. Contains metal alloy – worse esthetics
2. Grey shades by the tooth neck – metal does not allow light to go through
3. The shape – dental technicians must make the crowns larger in order to cover the metal
4. More filing – the dentist must file the tooth more because of the covering of the metal construction
5. Allergies – some people are sensitive to metal alloy and can cause an aftertaste in the mouth

The procedure of making PFM

1. Dentist’s office – filing the tooth down, impressions, choosing the shade
2. Dental lab – creating a model, transferring it into the computer using a 3D scanner
3. Dental lab – modeling on the computer
4. Dental lab – making in a CNC mill
5. Dental lab – coating done by hand, filing, polishing
6. Dentist’s office – fitting in the patient’s mouth, approval of both patient and dentist, cementing

Prevention is better than later treatment. The more care you take of your teeth and gums, the less time you will need to spend in the dentist’s office.
