Dental prostheses are made when we are unable to make fixed bridges due to insufficient number or position of the remaining teeth, when we cannot incorporate replacement implants, or when the patient simply does not want implants.
Partial Denture Prosthesis
We create a partial denture prosthesis when there is a sufficient number of preserved teeth in oral cavity. The denture prosthesis is connected to them with clasps or, even better, with joint connections, thus stabilizing it in the mouth and compensating for lost teeth.
When repairing partial toothlessness with partial denture prosthesis, we usually perform so-called combined procedure by applying the crowns on the remaining teeth and linking the partial denture prosthesis with special joint connections (clasps, anchors).
The crowns are fixed on the remaining teeth with cement agent, and the denture prosthesis can be clasped and unclasped, so they can be taken out from the mouth for hygiene.
This is a very good aesthetic and functional solution to partial toothlessness.
The clasps are hidden beneath the prosthesis, that come into contact with the crowns on which the joint connections are placed. There is no visible transition from the teeth with crowns and other teeth in the prosthesis.
When we perform combined procedure in the upper jaw, the denture prosthesis covers only the smallest part of the palate necessary, and the prosthesis is very firm and stable in the mouth.
Using the combined procedure, a very graceful prosthesis can also be crated, so it does not interfere with the tongue and is also very firm and stable.
Complete Denture Prosthesis
The complete denture prosthesis is created in the case of complete loss of teeth, when we cannot incorporate implants to compensate for the teeth or when the patient does not want the implants. In the upper jaw, the prosthesis covers the entire palate and tooth ridges to obtain a large enough surface to which the chewing pressure is transferred. In the lower jaw, the complete denture prosthesis covers only the dental ridges and has a shape of the horseshoe, because free space for the tongue must be obtained.
The complete denture prosthesis is held in its place in the oral cavity and stabilized by creating a vacuum under the prosthesis. For all these reasons, its design is very demanding because the edges of the prosthesis have to be precise and fit closely to the mucous membrane of the dental ridge, but should not scratch or otherwise interfere with tongue and cheek movements.
This is why a special technique of taking a functional print is performed when creating a complete dental denure prosthesis.
After meals, the complete denture prosthesis must be removed from the mouth to maintain its hygiene.
When the denture prosthesis is not in the mouth, it must be kept in water, to prevent it from being dried out and deformed. Such a prosthesis would not fit properly in the mouth, which would result in its sliding and falling out.
