PFM restorations have been around for many years. Also, this procedure is known by other names such as:
- Porcelain fused to metal (PFM)
- Metal ceramic crowns (MCC)
- Porcelain fused to gold (PFG)
- Porcelain fused to white gold (PFWG)
- Palladium ceramic crowns (PCC)
- Porcelain fused to semi-precious (PFSP)
- Gold ceramic crown (GCC)
Clinically, it is still some of the most used materials in dental prosthetic restoration. As a PFM dental laboratory in the US, we do not use nickel-containing alloys, since many patients are allergic to a nickel alloy.
All our metal alloys are FDA-approved and boast the best biocompatibility in the market today. Dental alloy certification comes with every alloy you choose. However, please let us know if your patient has any allergic reactions so that we can provide you with the most appropriate metals for your patients.
PFM For Long-Spanned Bridges
As porcelain fused to metal PFM dental laboratory, our technicians are trained to fabricate porcelain fused to metal (PFM) restorations using the best methods. The framework is critical, as the metal frame design is the foundation of all PFM restorations. Not only it must provide strong support but also the aesthetics of the crown by creating a uniformity of thickness between the porcelain layers, including the opaque, dentin, and enamel layers. If the metal design is not properly fabricated, then the porcelain design will not be precise. For this reason, we design our metal frameworks using CAD-CAM 3D technology to create the best foundation for porcelain fused to metal PFM crowns and bridges.
For the porcelain layering techniques, our technicians strictly follow the meticulous techniques taught in accredited dental technician education programs. We do not take shortcuts, even in layering porcelain powder. The shade of the final crown is built-in, not shaded over. Moreover, it allows the shade of the porcelain crowns and bridges to last for years to come, and not fade over time.
Although we do final glazing and shade correction, the base shade should come from the inside of the porcelain, not the outside.
As porcelain fused to metal PFM dental laboratory in the US, our porcelain produces a tooth with a smooth finished surface. Therefore, your patients’ oral care and health are not compromised by the tooth-to-tooth wear that can occur over time. This superior wear characteristic contributes to a longer lifespan for the restoration. A smooth finish also means less plaque (or stain) buildup on adjacent teeth.
The indications for PFM restorations are for
- Individual crowns
- Anterior restorations with dark shaded dentin colors
- Metal posts
- Posterior restorations
- Multi-unit bridges
- Full-mouth reconstruction
- And other restorations
In conclusion, The Art Of Aesthetics dental lab believes that porcelain fused to metal restorations combined with high precious alloys are the best materials for a long (multi-unit) spanned bridge. Let us know if you have any questions.
