SmCo5 magnets and ferromagnetic alloy, which were recently developed, have been used to the removable prosthesis, but are not used to the fixed one.
We have applied them as a retainer to the bridge pontic with the removable plate.
This pontic have following advantage:
1. It is easy to clean and to alter the pontic lower area attached to the alveolar tissue.
2. It is a simple apparatus.
Here we propound 2 typical cases with fine result.
