Fixed dental prostheses
Dental implants are the foundation for future dental prostheses, which can be either removable (so-called hybrid prosthesis), or affixed to the jawbone through a dental crown or a bridge (so-called fixed prosthesis). In some cases, it is possible to anchor even a removable dental prosthesis. In the area of creating dental prostheses, the SofiDent dental office cooperates with the best dental laboratories in Prague.
Fixed dental prostheses
The main characteristic trait of fixed prostheses is that the patient cannot remove them by themselves. The most notable fixed dental prostheses are crowns and bridges. Crowns are fixed on damaged teeth, or placed instead of lost teeth, and they usually replace bridges.
A dental crown is an artificial hollow tooth which is used to cover most of the surface of a tooth, or the entirety of it. In today’s world, there exists an entire array of crowns, which differ mostly in the material used to manufacture them. Therefore they are classified into metal, composite or porcelain dental crowns. Porcelain crowns are further divided into porcelain-fused-to-metal, zirconia and pressed porcelain crowns. Depending on the exact issue at hand, our dentists will recommend the most suitable material to you.
Aesthetic porcelain crowns, also known as all-porcelain dental restorations are the pinnacle of modern aesthetic dentistry. They are “metal-free” dental crowns, where the only used material is dental ceramic, which is adjusted to match the tone of natural teeth. During the placement of a dental crown, layers of different shades of dental cement are applied to the treated tooth.
All-porcelain crowns are not only highly aesthetic, but also mechanically resilient enough to be used on frontal teeth and molars. An all-porcelain dental crown can be affixed both onto a natural tooth and an implant.
The most commonly used materials used to manufacture all-porcelain dental crowns are lithium disilicate (E-Max crowns) and Zirconia. Both materials are of high quality and complement each other well. Lithium disilicate is affixed through the use of adhesives, Zirconia needs to be cemented. Compared to Zirconia crowns, E-Max crowns reach a higher degree of aesthetics. The adhesion method is also of advantage, as it guarantees a higher degree of sealing at the gingival margin, and thus less risk of cavities forming.
A bridge is an artificial tooth bridged between two crowns, which is firmly attached to the neighbouring filed teeth through the use of the two crowns. There are three main types of dental bridges: traditional, implant-supported and Maryland. A traditional bridge is used when there are healthy teeth on either side of the gap, which are then filed, so a crown can be placed.
Implant-supported bridge is used when the patient does not have sufficiently healthy and sturdy teeth to support the bridge, or when the patient is missing several teeth. This type of a bridge is anchored to dental implants, which are surgically placed into the jawbone for the purpose of this procedure. A Maryland bridge is used when the gap is in the front most part of the teeth arch.
