Replacement of teeth
Dental bridges literally bridge the gap created by one or more missing teeth.
A bridge is made up of two or more crowns for the teeth on either side of the gap. These two or more anchoring teeth are called abutment teeth and a false tooth/teeth in between. These false teeth are called pontics and can be made from gold, alloys, porcelain, or a combination of these materials. Dental bridges are supported by natural teeth or implants.
- 1. Restore your smile
- 2. Restore the ability to properly chew and speak
- 3. Maintain the shape of your face
- 4. Distribute the forces in your bite properly by replacing missing teeth
- 5. Prevent remaining teeth from drifting out of position
There are three main types of dental bridges:
- 1. Traditional bridges involve creating a crown for the tooth or implant on either side of the missing tooth, with a pontic in between. Traditional bridges are the most common type of bridge and are made of either porcelain fused to metal or ceramics.
- 2. Cantilever bridges are used when there are adjacent teeth on only one side of the missing tooth or teeth. This is not very common any more and is not recommended in the back of the mouth where it can put too much force on other teeth and damage them.
- 3. Maryland bonded bridges (also called a resin-bonded bridge or a Maryland bridge) are made of porcelain, porcelain fused to metal, or plastic teeth and gums supported by a metal or porcelain framework. Metal or porcelain wings on each side of the bridge are bonded to your existing teeth.
DENTURES AND PARTIAL DENTURES
A denture is a removable dental appliance that replaces missing teeth and surrounding tissue. They are made to closely resemble your natural teeth and may even enhance your smile.
There are two types of dentures: complete and partial dentures. Complete dentures are used when all of the teeth are missing, while partial dentures are used when some natural teeth remain. A partial denture not only fills in the spaces created by missing teeth; it also prevents other teeth from shifting. A complete denture may be either “conventional” or “immediate.” A conventional type of denture is made after the teeth have been removed and the gum tissue has healed, which usually takes 4-6 weeks. During this time, the patient will go without teeth. Immediate dentures are made in advance and are immediately placed after the teeth are removed, thus preventing the patient from having to be without teeth during the healing process. Once the tissues shrink and heal, adjustments will have to be made. Dentures are very durable appliances and will last many years, but may have to be remade, repaired, or readjusted due to normal wear.
These prostheses are designed for patients who have lost all their teeth and cannot wear conventional dentures due to severe bone loss. With the aid of dental implants, which are surgically placed inside the bone, free-standing attachments are used to retain the overdentures. The advantages are: enhanced chewing capacity, esthetics, phonetics, ease of maintenance, simplified hygiene, retention and stability as well as maintenance of existing bone.
FIXED (PERMANENT) DENTURES
This is another alternative for patients who have lost all their teeth. Also known as “Fixed Detachable”, this implant prosthesis has the "feel" and chewing effectiveness of natural teeth. Most patients find their fixed-detachable prosthesis to be excellent therapy. It can only be removed by the dentist, and its removal requires a great deal of time and expertise.
