Dental Bridge Procedure

What Dental Bridge?

One or more missing teeth can affect the appearance and functionality of your smile. Missing teeth can cause a change in occlusion (bite), tooth movement, temporomandibular joint disorder (TMJ), speech disorders, increased risk of periodontal disease and a greater chance of tooth decay dentistry. Dental bridges are used to replace missing teeth. There are several types of fixed dental bridges (can not be deleted), including conventional fixed bridges, cantilever bridges and resin-bonded bridges. In general, conventional and cantilever bridges require the development of teeth around a missing tooth. Crowns are then placed on the teeth shaped and attached to an artificial tooth (pontic called). A Resin-bonded bridge requires less preparation of adjacent teeth. It is often used to replace the front teeth, provided the gums are healthy, adjacent teeth do not have many dental fillings.

Dental bridge procedure

During the first visit, the dentist will examine the health of gums and teeth others to judge whether you are a candidate for a dental bridge. If you are a candidate for a dental bridge, you are given a local anesthetic so your dentist can prepare the teeth required to support the bridge. If the support teeth are decayed or badly broken down, your dentist may have to rebuild them before they can be used as support teeth for a bridge. Next, your dentist makes an impression of prepared teeth with a material like putty is used to create a model of your teeth. Your bridge is fabricated based on this model by a trained laboratory technician so that it exactly fits the prepared teeth. It is important that your restoration fits perfectly to avoid oral health problems such as dental caries. While your bridge is in process, your dentist will be a temporary bridge for teeth and gums can be protected against damage until your permanent bridge is ready. To complete the dental bridge procedure, you must return to the dental clinic for a second visit to the bridge fitted and cemented.

Case selection and treatment planning

When a single tooth requires a crown, the prosthetic crown will rest most cases on the structure of your teeth which was originally supported the crown of the natural tooth. However, when restoring an edentulous area with a bridge, the bridge is almost always restoring more teeth than there are deep structures in support. For example, in photo at right, the 5-unit bridge will be supported on three pillars. To determine whether or not the abutments can withstand without failure a bridge to a lack of support structures remaining root, the dentist uses Ante rules which states that the roots of the abutment teeth must have a combined surface in three dimensions is more that the structures of the roots of missing teeth replaced by a bridge. When the situation presents a poor prognosis for proper support, double abutments may be necessary to fully comply with Article Ante. When a posterior tooth for a tooth has been a pillar intracoronary restoration, it might be preferable to the bridge abutment in an inlay or onlay instead of a crown. However, it can concentrate the torque forces of chewing on a wraparound less food, which makes the bridge more prone to failure. In some situations, a cantilever bridge may be constructed to restore an edentulous area that has teeth as abutments for adequate mesial or distal. It must also comply with Article Ante, but because there are just stops on one side, a modification of the rule must be applied, and these bridges have double stop.
