WHAT ARE DENTAL PROSTHETICS?
The primary purpose of non-removable prosthetics is to solve a wide range of problems associated with entirely or partially missing teeth in the upper or lower jaw. This method allows restoring the shape and aesthetics of teeth, compensating for missing teeth. The placement of artificial dental structures is required in case a person has the following dental problems:• increased attrition of enamel;
• diastemas, cracks, chips;
• a dental crown is missing, and there is no other way to restore it;
• one or more missing teeth, as well as edentulism.
HOW REMOVABLE DENTURES ARE ATTACHEDSeveral factors influence the way the removable dentures are fixed. Such factors include:
- degree of mobility, size, and position of the tongue in the oral cavity;
- some anatomical features of the prosthetic bed, palate, and alveolar ridge;
- lack of dental precontact.
Attachments or locks. This fixation method is not often used when installing removable dentures, but it is often used when installing fixed structures. Attachments can be used for partial edentulism when there are no more than two teeth in the patient’s mouth. The patrix or fitting part of the attachment can be located in the root or crown part of the abutment tooth.Clasps and hooks. ТThis type of fitting is used mainly for removable prosthetics, and the fixing devices and the dentures are made of similar material. Acrylic, polyurethane, and nylon dentures have fixation devices, while removable clasp dentures are equipped with metal hooks.
Suction cup or flexible dentures. This method of attachment is used when installing a complete denture or overdenture. The attachment mechanism of such devices is based on the adhesion or natural vacuum effect of suction.Implants. Removable implant-retained dentures can be fixed by a bar or ball attachment.

Disadvantages of complete dentures:
The denture in the upper jaw blocks the palate, which can result in a partial loss of the taste sense and sometimes a feeling of nausea.
A complete removable denture is fixed only with glue; it is not particularly stable and can move during chewing; this can negatively affect speech and mastication.
It should be brushed after every meal.
