Reliable and Robust Solutions Backed by Years of Experience
It is a type of traditional restoration that has been successfully used in dentistry for many years. Metal-supported porcelain crowns feature a special metal framework on the inside to ensure durability, while the outer surface is covered with tooth-colored dental porcelain to provide an aesthetic appearance.
Why Are Metal-Supported Porcelains Needed?
-
High Masticatory Pressure: It is preferred—particularly in cases of extensive tooth structure loss in the posterior regions (molar teeth)—due to its high resistance to masticatory forces.
-
Long-Span Bridge Restorations: In cases involving the loss of multiple teeth where long-span bridges are required, the metal framework serves as a robust structure that resists fracture.
-
Functional Needs: It offers an effective solution for cases where aesthetics are not as critical as in the anterior region, but maximum durability is required.
How does the treatment process proceed?
Once the existing teeth have been shaped for the restoration, an impression is taken. In the laboratory, a thin metal framework that fits precisely onto the tooth is cast first. The fit of this metal framework is then verified in the clinical setting (metal try-in). After the fit is confirmed, the metal is layered with porcelain matching the color of the patient’s adjacent teeth, fired, and cemented onto the tooth.
Frequently Asked Questions
Do metal-supported porcelains look like metal from the outside?
No, the metal framework is located only within the interior of the restoration. When viewed from the outside, the white or tooth-colored porcelain is visible.
Can it be used on front teeth?
It can be used; however, since the metal substructure blocks light transmission, it may not fully replicate the translucent appearance of natural teeth. For this reason, materials with high light transmission, such as zirconia or E-max, are generally preferred for the anterior regions.
Conclusion
Metal-supported porcelain restorations are a highly durable prosthetic option that compensates for extensive functional loss—particularly in posterior teeth—and supports chewing dynamics.
