Repair and Protect Teeth with Dental Crowns and Bridges
When Do You Need a Crown?
Crowns, sometimes referred to as “caps” can be placed for a multitude of reasons. Most commonly, people get crowns if:
- The tooth structure is not strong enough to restore a tooth with a filling
- The tooth is deformed or or has an irregular shape, structure, or color
- The tooth needs to be used as an abutment for a fixed or removable bridge.
- You recently had a root canal performed. Crowns can help reinforce the tooth to prevent cracking after the invasive procedure.
What are Crowns Made Of?
Crowns are fabricated for permanent restoration by casting metal or by casting metal and bonding porcelain. Non-metal crowns are also available and can be made with zirconia. porcelain, or ceramic materials. Today, porcelain crowns are more popular than metal crowns and can be made to blend in with your natural teeth.
When determining the best materials for your crown, we feel it's important to favor quality over price. We, at Berger Dental Group, use the finest materials and abide by ADA (American Dental Association) standards, and we hold our laboratory companies accountable for the highest performance level and best materials. They are not inexpensive, and they do excellent quality of work.
How Is a Crown Made?
Traditionally, metal is cast and porcelain is bonded to the metal producing an esthetic crown or restoration. These materials have improved vastly and make for excellent results.
The old porcelain crowns were very fragile, but purely tooth-colored restorations have progressed a long way. Milling of restorations is a common technique and CAD-CAM crowns are commonly used. The various techniques include different cameras that take video impressions in the mouth or video impressions in the lab of models poured in stone in a laboratory.
There are fine points of validity of each technique and the use of the systems should be understood by all good dentists, we do both here.
Dental Crowns and Bridge Procedures
Fixed bridge work is an extension of crown therapy to replace missing teeth. Crowns are usually placed at each end of a space and replacement teeth are attached to and between the crowns. This enables a functional and esthetic bridge that is stable. On occasion we construct a cantilever bridge which has a replacement tooth affixed to the crowned tooth or teeth and has support only on one side. Special support and stress management must be considered when a cantilever bridge is used.
At Berger Dental Group, we make fixed bridges that are esthetic, functional, and cleansable. We carefully evaluate the abutment teeth as to their suitability for support for long-term success.
As non-metal bridges become stronger, more may be used. Breakage is still a problem in large non-metal bridges. Therefore, one must be careful in advocating such restorations for all cases.
Bridges and crowns are used routinely on implants. It is advisable to not include natural teeth and implants on the same bridge due to the different root attachments of teeth and implants. However, most rules are not always or never. We try to avoid the mix of the two.
