If there is no tooth left in the mouth to be used as a support, force transmission, support and retention are provided by the prosthesis sitting on the tissue surface. Completely tissue-supported prosthetic applications are called total prosthesis. This type of prosthesis is also known as palatal prosthesis. In total dentures, lip and cheek fullness can be provided with the prosthesis, allowing the face to have a younger appearance. In addition, it is possible to achieve a beautiful smile by aligning all teeth in accordance with aesthetic rules. Total dentures are mobile because they receive support from the tissue. Especially the fact that the lower palate has less volume than the upper palate and the presence of the tongue in the lower jaw makes the lower denture more mobile than the upper denture. The general complaint of patients is that; my upper palate is holding, but my lower palate moves when eating and talking. Due to this movement, frequent impacts occur.

Although bonding total dentures with special adhesives reduces complaints in some cases, the best method to eliminate this problem is the production of overdenture dentures, which are applied with special holders on the implant and are known as snap-on dentures among the public. In recent years, full dentures made by placing implants in the jawbone and supported by these now give patients the feeling of chewing with their own teeth and are frequently preferred for this reason.

3. FIXED DENTURES

FIXED DENTURES; ARE DENTURES THAT ARE ADHESIVED BY A DOCTOR ON NATURAL TEETH, TOOTH ROOTS OR DENTAL IMPLANTS AND ARE NOT REMOVABLE BY THE PATIENT. IT IS A GENERAL TERM USED TO DEFINE CROWN AND BRIDGE DENTURES. IT IS THE MOST PREFERRED TYPE OF DENTURE IN FUNCTIONAL RESPONSES IN TOOTH MISSINGS. WHEN A FIXED PROSTHESIS IS MADE, REDUCTION OF SOME TEETH IN THE MOUTH FOR SUPPORT PURPOSES IS A PROCEDURE THAT PATIENTS ARE USUALLY CONCERNED ABOUT.

Chewing will be easier and more comfortable with a fixed prosthesis. In cases of missing teeth, using the remaining natural teeth in the mouth will put too much pressure on these teeth and cause problems in the teeth and gums.

The teeth around the toothless area will move towards this gap. Due to the displacement of these teeth, the closure of the lower and upper jaws will change, pain in the jaw joint, facial muscles that provide chewing and speaking, and perhaps more serious problems will occur. In some cases, the pain can spread to the face, head, neck and back.

There will be positive changes in speech and appearance with the fixed prosthesis. Because tooth positions play an important role in speech, supporting the lips and cheeks.

How is it applied?

Fixed dentures can be applied with or without metal support. While metal-supported fixed dentures provide sufficient resistance to functional forces in the mouth, they cause aesthetic problems and in some cases can negatively affect the natural appearance. The most important reason for this is that the direct passage of light from the tooth is prevented by the metal.

Due to these disadvantages of metal-supported ceramic restorations, ceramics resistant to fracture have been developed. Zirconium in particular is the most up-to-date material used in this field.

The correct indication is the most important stage in a successful treatment. Respecting the knowledge and experience of the physician in the selection of the material to be used is necessary for the success of the treatment.
