Metal-supported porcelain

Metal-supported porcelain veneers are a type of porcelain crown with a substructure. 

It is divided into two;

1. Internal structure – substructure: This layer provides strength to the tooth.
2. External coating: Porcelain, or ceramic, coatings provide the tooth's own natural and aesthetic appearance.

From the outside, it looks like porcelain, but the part supporting the tooth's substructure is metal.

In which situations should we prefer it?

Generally, large molars are preferred for chewing and for foods that require force. 

Broken teeth, decayed old fillings, and teeth where fillings will no longer hold should all be considered.

It is also a preferred choice for implant-supported crowns.

It is a preferable option because it is more budget-friendly than zirconium porcelain.

Production Process

First, an examination and patient planning are performed. Then, the patient's preparation phase begins; any necessary procedures are performed beforehand. Afterwards, the tooth is prepared, and the impression-taking stage begins. Digital or manual impressions are taken and sent to the laboratory, where a metal substructure trial is performed. If the metal substructure is compatible with the mouth, a color selection is made in consultation with the patient, using a color scale to match the other teeth. The porcelain is then sent to the laboratory to be processed on the metal base according to the chosen color. The shape of the tooth is checked, its harmony with other teeth is evaluated, and the aesthetic appearance in the bite is assessed. If necessary, the crown is sent back to the laboratory for minor adjustments. Finally, the color and shine of the crown are checked. If everything is satisfactory, the inner surface of the crown is cleaned, and the cementation process begins. During cementation, marginal fit, gingival harmony, and bite are evaluated to complete the process.

Control

The patient is scheduled for a follow-up appointment in one week, and any height difference in the tooth will be corrected. 

Things to keep in mind:

Avoid harsh brushing and hard foods. A check-up appointment is also required every 6 months.
