Need of St Louis Cosmetic Dentist For Dental Bridge And Crown
It is important to understand that the loss of teeth from the mouth can cause changes that create serious dental problems. Some of the problems created by tooth loss include disruption to aesthetics and interference with speech; disruption of chewing efficiency; and remaining teeth becoming unstable therefore consulting the St Louis Cosmetic Dentist is the best solution. The teeth on either side of the spaces can 'tip' into the space. Teeth opposing a space can over erupt into the space. Tipped and over-erupted teeth can interfere with occlusion and function. Tipped teeth can create areas that are difficult to clean and render the region more prone to periodontal disease and decay. For these reasons we generally try to restore spaces to protect individual teeth and maintain the stability of the remaining dentition. Missing teeth can be replaced in three ways — with a denture, a bridge or implants. A denture is removable. The patient can take it out. A bridge or implant-supported crown is fixed and not removable. A dental bridge is very similar to a bridge over a stream. It consists of a span supported at both ends. Teeth are required at both sides of a space for a bridge to be possible. Bridges may be used to restore small spaces caused by the loss of one or two teeth.
There are two types of bridges. Conventional bridgework is usually made out of porcelain and gold alloy and is cemented on to prepared abutment teeth. Resin-bonded bridges are simpler in form. They may be made out of non-precious or gold alloy and porcelain. They are bonded to the abutment teeth. The fixed bridge feels like the patient's own teeth. They can chew or laugh without fear of the appliance moving or dropping. The patients clean the bridge as if it were their own teeth. The fixed bridge does not interfere with speech, or encroach upon tongue space. The fixed bridge is aesthetic. Most teeth requiring crowns are broken down. In order to prepare an ideal crown preparation it is necessary to rebuild the original tooth form. In a vital tooth this is called a core restoration and may be constructed of amalgam, composite resin or glass ionomer.
In a non-vital tooth, a lot of tooth structure has been lost. In order to retain the core restoration, part of the root canal space and pulp chamber is used for retention. This is called a post and core restoration. It may be made directly of either amalgam or composite resin and prefabricated post or it may be made indirectly and completely cast from gold. In a direct post and core restoration a prefabricated post is selected and cemented into the canal space. Amalgam or composite resin is then packed around the tooth to restore it to normal form. The tooth is now ready for crown preparation. An indirect post and core is made from an acrylic pattern or impression of the tooth. Make sure to choose the best st louis cosmetic dentist for aesthetic dental surgery or crowning or bridge.
