The type of dental prosthesis to be applied, which has an important role in the treatment of missing teeth, is determined by your dentist in a way that best protects your oral and dental health.
What is Fixed Prosthesis?
Fixed prosthesis is the process of rebuilding teeth with excessive loss of material or missing teeth using materials similar to the color and texture of the surrounding teeth. There are several material options for this process, also known as crowning, depending on the structure of your tooth. There are different material alternatives such as metal, metal-supported porcelain crowns, reinforced porcelain or zirconium-based full porcelain crowns, metal crowns.
Metal Supported Porcelain Crowns: These are prostheses made with aesthetic porcelains placed on a metal substructure.
Full Porcelain Crowns: Metal-free full porcelain crowns can be used in front teeth where aesthetics are important to achieve a similar appearance to natural teeth.
Metal Crowns: These are crowns made entirely of metal such as gold, chrome and cobalt. Unlike full porcelain crowns, the usage areas of metal crowns are limited and they are suitable for use in the teeth in the posterior region that will not be aesthetically problematic and in areas where full porcelain crowns cannot be used.
What are the stages of Fixed Prosthesis?
The final form of fixed prostheses involves a minimum of 4-session treatment.
Preparation and Measurement: The tooth or teeth to be restored are reduced according to the amount of restoration to be applied, and the precise measurement of the mouth is taken for the laboratory model and procedures. The color to be used on teeth is determined by the joint decision of the patient and the dentist.
Infrastructure Rehearsal: A rehearsal is made to see how the zirconium or metal substructure prepared on the model will be placed in the mouth.
Porcelain Rehearsal: It is the stage before the restoration is completed. The connection of the porcelain prepared in the laboratory with neighboring, opposite teeth and surrounding tissues is checked. After the aesthetic and color harmony control, the final approval is obtained from the patient. The prosthesis is sent to the laboratory to be polished.
Polishing and Cementation: The restoration, which is polished in the laboratory, is tried in the mouth, if there is no problem, it is fixed on the tooth after the approval of the patient, and the residues are cleaned after the adhesives have hardened.
All oral hygiene and care has a direct impact on the life of the restoration. The patient is informed if there are methods required for bridges. An appointment is made for routine controls.
What is Removable Prosthesis?
These are appliances that can be inserted and removed by the patient and that replace missing teeth. Various types are available including total prosthesis, partial prosthesis, immediate prosthesis, and crowns.
Total prosthesis are prostheses, also known as ‘dentures’, made with the support of the bone tissue left in your lower and upper jaw when you have no teeth of your own in your mouth. It is preferred in cases which an implant cannot be used. Plastic teeth made of special materials are used instead of porcelain teeth in total prosthesis.
Partial prosthesis is a type of removable prosthesis that are preferred as an alternative to implants in cases which you have a part of your own teeth in your mouth and the other part is removed.
Partial prosthesis is made of acrylic or one piece cast. This type of prosthesis provides retention with wires connected to the main teeth.
In cases which all the main teeth need to be removed, one of the alternatives for those who do not want to be toothless are the prostheses called ‘immediate prostheses’ that are placed immediately as soon as the natural teeth are removed. When the healing is completed and the tissues become incompatible with these prostheses, the patient’s permanent prostheses start being built.
Prostheses applied on natural teeth or roots in the mouth are called dental crowns. The natural teeth or roots on which the prosthesis fits provide grip and stability to the prosthesis.
