A complete denture is a removable acrylic prosthesis that replaces all of the teeth in a dental arch. Complete dentures are generally inexpensive, simple to make and repair, and offer a level of aesthetics and functionality that many patients find acceptable.
The artificial teeth and the base of the denture are the two main parts of a complete denture. An artificial tooth is used to look like and function like a real one, as well as to help people pronounce words more clearly. This is how it works: An artificial tooth's base is called a "dental base." It can be used to repair soft and hard tissues that have been damaged. When you bite, the force comes from the denture base to the oral mucosa and bone tooth. To make up for the fact that there is no tooth support, complete dentures have denture bases that cover more of the mouth's surface than those of RPDs. This is because complete dentures do all of these things. A major connector isn't used with complete dentures because there is no room for it on the complete denture, and there is no healthy abutment for a minor connector because there is no room for it.
Both sub-pressure and adhesion to the tissue under a full denture help keep it in place.
It will happen if the denture base and oral mucosa are attached close to each other and a good peripheral seal is put on them. Peripheral seal is the tight contact made by the denture's marginal surface with the oral mucosa. This is called a peripheral seal. In order to speak, the posterior edge of the upper denture (the postdam area) is very important. The pressure outside the dental base pushes it down on the oral mucosa. Good adsorption is mostly due to a thin sticky layer of saliva that forms between the dental base and the oral mucosa. This layer helps the substance stay in place. Thus, a large area of dental bone is needed to make sure that the dentures stay in place. It should, of course, not mess with normal oral function or make you less comfortable.
It's important to think about how oral hard and soft tissues might affect how well a prosthetic is held in place when making a plan. A denture can't stay in place if there are large tubes, sharp bone apexes, or hyperplastic oral mucosa. If these problems aren't fixed before prosthetic treatment, the chances of keeping full dentures in place would be dramatically reduced. if the jaw bone has been sucked in, making it smaller and flat, or the oral mucosa has lost its original elasticity and thickness, the chances of keeping something in your mouth are much lower. There may be times when more connections, like implants, may be required.
