What are a fixed protodontics?
Fixed prosthetics are permanent prosthetics used to restore dental acts to replace the decay or missing teeth or parts of teeth. Common examples of solid prosthetics include inserts, porcelain veneers, crowns and bridges. They can be made of metal, porcelain or resin and may last five to 15 years.
The smallest types of fixed prosthetics are inserts, onlays and porcelain veneers; These fillings cover only part of the tooth. The crowns are used to fill a large part of the cavity along the visible tooth, while the bridges are the largest fixed prosthetics and replace one whole tooth or two adjacent teeth. A good candidate for fixed prosthetics has healthy supporting tissues and supporting teeth that promote return. In addition, the patient must be helpful and able to practice good oral hygiene, including brushing of the prosthesis and surrounding tissues at least once a day. Some types of renewal will require a special fiber to make dental intake.
Most of the fixed proofontics are produced in a dental laboratoryI and within a few days is sent to the dentist's office. To build well, the dentist has the impression of teeth; To achieve the best impression, gingival tissue tissue is pushed back with a retction cord or other method. In some situations, the dentist provides a temporary prosthesis to alleviate the pain until permanent restoration is prepared.
Before the permanent connection of the prosthesis, the dentist must prepare the tooth by removing any decaying tissue. Both hand cutting as well as rotary tools can be used to provide the rubber and outline of the upper tooth to provide a better space to connect the prosthesis. If the tooth has a large disintegration or fracture, the dentist can provide retention aids such as the accumulation of the core, the retirement of pins or the post office and the core that helps to support the recovery.
A wide range of friends can be used to create a fixed protection depending on the patient's specific needs. Different metals such as alloy zlATA or nickel alloy, generally lasts the longest, but many patients do not like the appearance. On the other hand, porcelain and ceramic fillings that achieve the best color match, often chip and wear of opposite teeth.
roasting made of porcelain and metal lasts longer, but are still prone to fractures. All protecttony resins are the cheapest available; However, they tend to wear quickly and easily. Many patients choose porcelain for highly visible front teeth and longer -lasting metal for less noticeable stool fillings.
