A fixed bridge is an excellent way to replace 1 or 2 missing teeth. It is permanently cemented into place and can not be removed by the patient. A bridge consists of a pontic (false tooth) joined on both sides by crowns that adhere to the natural teeth adjacent to the missing tooth. Fixed bridges prevent remaining teeth from shifting, restore esthetics, and maintain function.
A fixed bridge can be constructed from gold alloys, non-precious alloys, porcelain, or a combination of these materials. Porcelain is often bonded to either precious or non-precious metal. It is not uncommon for bridges to be replaced after 7-10 years although they can last significantly longer.
Fabrication of a fixed bridge typically takes about 3 visits over the course of 4-6 weeks. The first visit involves preparing the teeth on each side of the missing tooth, taking a final impression for the lab, and creating a customized temporary bridge to be worn while the permanent bridge is fabricated by the lab. At the second appointment, the metal framework of the bridge is tried-in to confirm proper fit. If the metal framework fits well, it is sent back to the lab to have the porcelain placed. Finally, the completed bridge is tried in and adjusted. If everything is perfect, the bridge is permanently cemented ready for use.
A strict regimen of brushing and flossing will help keep your bridge and surrounding teeth clean and healthy. Bridges are a bit more difficult to clean because the teeth are all joined together, requiring the use of a floss-threader. If you do not clean around your bridge properly, periodontal (gum) disease and/or secondary decay may result. This is of critical importance as your bridge relies on the neighboring teeth for support.
Removable bridges, as the name implies, can be taken in and out by the patient. Partial Dentures can be very effective when multiple teeth in one arch are missing or when a conventional fixed bridge or implant cannot be used. RPD’s replace missing teeth, offer proper lip and cheek support, and restore proper function. The RPD is made from a very light weight metal framework with pink (gum colored) acrylic and plastic teeth on top. They attach to the remaining natural teeth with metal rests and clasps; as well as rest on top of the gums where teeth are missing. Over time, they can accelerate bone/tissue loss (resorption) and can often result in poor esthetic appearance due to the metal clasping of the teeth. Occasionally, the supporting natural teeth can be adversely affected as well, due to the excess stress and strain placed on these teeth by the RPD. Also, the support and retention of a RPD is much less ideal as compared to that of a fixed bridge or dental implant.
It is not uncommon for partials and dentures to be replaced after 5years and/or relined (every couple years), although they can last longer.
Fabrication of a RPD involves impressions, a few try-in appointments, followed by final delivery and an adjustment period. The entire process takes about 4-6 weeks.
