Fixed prosthodontics is the area of prosthodontics focused on permanently attached (fixed) dental prostheses. Such dental restorations, also referred to as indirect restorations, include crowns, bridges (fixed dentures), inlays, onlays, and veneers.
Dental Bridges
A missing tooth can mar even the most beautiful smile, but our cosmetic dentists can restore beauty to your smile. Cosmetic dental bridges are made of natural, tooth-colored materials. In the gifted hands of our dentists, we can seamlessly replace a tooth lost by disease or injury.
A dental bridge is a device used to fill the space where a tooth has fallen out or been removed. A typical dental bridge consists of a pontic (a filler tooth) that is attached to two surrounding abutments (dental crowns). Once complete, this dental bridge structure is bonded into the mouth. Without the use of a dental bridge, spaces in the mouth from missing teeth can cause multiple teeth to shift, lead to occlusion (biting) and/or jaw problems and spur periodontal disease. Dental bridges safeguard the integrity of existing teeth and help maintain a healthy, vibrant smile.
Types of Dental Bridges
A cantilever dental bridge is often used when there are teeth on only one side of the span. A typical 3 unit cantilever dental bridge consists of two abutment dental crowns that are positioned next to each other on the same side of the missing tooth space. The pontic is then connected to the two dental crowns, which extend into the missing tooth space.
Another dental bridge design is a composite bond, known as a "Maryland" dental bridge. This type of dental bridge is commonly used to replace the front teeth. The pontic is attached to metal bands that are bonded to the abutment teeth, and the metal bands are hidden with a white-colored composite resin.
There are several different types of dental bridges. The first is a fixed dental bridgewhich consists of a filler tooth (a pontic) that is attached to two dental crowns. The dental crowns fit over the existing teeth to hold the dental bridge in place. The fixed dental bridge is the most popular bridge.
Dental Bridge Process
Dental bridges usually require two trips to the dentist’s office. During the initial visit, the surrounding teeth are numbed with a local anesthetic. The dentist prepares the surrounding teeth by cleaning any plaque or decay that remains and reducing them so that the dental crowns can be fitted. The dentist makes a mold of the teeth and sends it off to a dental lab, where the customized impression is prepared. The customized mold takes one to two weeks to return to the office. In the interim, patients are fitted with a temporary dental bridge constructed of acrylic resin. When the patient returns to the dental office, the dentist removes the temporary dental bridge and replaces it with the permanent one. The dentist then adjusts the dental bridge for the proper bite and fit, and the dental bridge is permanently bonded into the mouth.
If the missing tooth space has no surrounding teeth, the dentist may decide a dental implant is the most appropriate choice. When a series of teeth are missing, the dentist may suggest a partial denture as the most effective way to maintain the structure of the jawbone.
Dental Crowns
Dental crowns can help restore shape, size and strength of teeth as well as enhance your overall look. Teeth impact your oral health as well as your smile and facial appearance. It is the first thing people notice when you speak. If you are looking for a long term solution to weak, chipped or broken teeth, this might be exactly what you need. Consult an experienced dentist to determine if crowns are the right solution for your dental problems.
What Are Dental Crowns?
A dental crown (also known as a cap) is placed over a tooth when a conservative restoration is insufficient to restore form and function. The crown, when cemented into place fully encases the entire visible portion of a tooth that lies at and above the gum line. Crowns are often necessary because of broken down old fillings, fractured or chipped teeth and following root therapy. They can also be used to improve the appearance of natural teeth that are malformed, mis-positioned or discolored.
How will you benefit from dental crowns?
Dental crowns offer both restorative and cosmetic benefits:
- They protect a weak tooth from decay
- Hold together parts of a cracked tooth
- Strengthen and protect the remaining tooth structure
- Restore a broken tooth or one that is worn down
- Cover and support a tooth with a large filling when there isn't a lot of tooth left
- Hold a dental bridge in place
- Cover misshapen or discolored teeth or a dental implant
- Make a cosmetic modification
