Zirconia has been carefully studied for its biocompatibility and has been found to have good compatibility with tissues. It is an attractive material for people who would prefer to have metal-free bridges because of metal allergies. Although allergies and sensitivities to dental alloys are quite rare, it is still something that should not go unnoticed. In this case, a zirconia bridge is a great biocompatible and highly aesthetic choice.
Bloomzir® zirconia bridges are milled from a single monolithic piece of ceramic. This monolithic milling process results in zirconia being nearly indestructible, withstanding the most vigorous chewing and biting activities. In fact, zirconium is five times as strong as porcelain, so its nickname: ceramic steel.
For many years the industry standard for fixed bridges were porcelain fused to metal, often called “PFM bridges.” These restorations provided good aesthetics and are resistant to wear. However, since technology and research has progressed, newer all-ceramic materials have been introduced, some of which were ideal for restorations within the aesthetic zone. Unfortunately, they lack the strength and durability required for posterior restorations. For example, lithium disilicate, is generally only suitable for anterior restorations. Sometimes, depending on circumstances, these dental ceramics will fail in the connector area. Therefore, Increasing the connector size could affect aesthetics and functionality.
A good bridge by Bloomden zirconia
The characteristics of Bloomzir® zirconia for a good posterior bridge as well as an anterior bridge. Studies have shown the survival rates for zirconia bridges have held up quite well over a five-year period.
Consists of multiple crowns
A dental bridge consists of a unit of multiple dental crowns held together and are used to replace missing teeth or “bridge” the gap between healthy teeth. The two crowns on either end of the bridge are fixed over the top of the supporting teeth on either side of the gap. Depending on both the number of teeth missing and number of healthy teeth available, a dental bridge can replace as minimal as one tooth to as much as a full arch of teeth.
Bloomzir® zirconia STML is monolithic and made from pure zirconia. This material has a high flexural strength of 1100 MPa while still maintaining lifelike 43% translucency. It also has a natural opalescence. Multilayer zirconia is extremely strong and is an ideal material for patients. Multilayer zirconia is particularly good for posterior bridges or where the tooth preparations are discoloured or have been endodontically treated. Due to the higher opacity of nultilayer zirconia.
Anterior bridge translucency
Bloomzir® zirconia can be the ideal choice for anterior bridge restorations provided the proper selection for Max. 49% translucency. These CAD/CAM-generated restorations provide an excellent and very precise marginal fit which when combined with exceptional aesthetics can help to increase patient satisfaction.
