These are the types of prostheses created by adhering the structures prepared on the models obtained from the measurements taken after the preparation on the tooth in a way that they remain fixed on the tooth by adapting to the mouth.

Advantages of Fixed Dentures

• Prostheses are hidden because they cannot be removed by the patient.
• They are generally more natural and aesthetic than a removable prosthesis.
• They provide better chewing than removable dentures.
• It does not contain prosthetic material that extends behind the palate or under the tongue.

Disadvantages of Fixed Dentures

• Where natural teeth are lost, bone loss occurs.
• Healthy adjacent teeth that will support bridges have to be prepared.
• Potential gum discomfort increases.
• Problems may occur in long-term aesthetics such as gingival recession.
• It is difficult to maintain oral hygiene because of the parts around the bridge where bacteria can grow.
• Potential for mouth odors.
• Decays may occur on the teeth and roots under the bridge.

Overdenture Dental Prostheses

When there are excessively curved, crooked and elongated teeth that will create incompatibility with the part to be prosthetic, instead of losing these teeth, the lengths of these teeth can be shortened and telescope crowns or precision retainers can be applied on them. These are the approaches where the abutment tooth is molded in the prosthesis and the movable prosthetic structure is applied on it.

They are overdenture prosthetics. Keeping the root of the tooth in the mouth will prevent osteoporosis and preserve the intraoral detection feature.

Total Prostheses

If there is no tooth left in the mouth to be taken as a fulcrum, force transmission, support and retention are provided by the prosthesis sitting on the tissue surface. Fully tissue-supported prosthetic applications are called total prostheses.
