Introduction
The term dental prosthesis covers all devices whose manufacture serves to replace missing, natural teeth. In general, dentures used today are divided into two major groups, fixed and removable dentures. While the group of fixed dentures includes fillings, bridges, partial and full crowns, partial and full dentures are considered to be removable dentures.
A partial denture is used to replace individual missing, natural teeth. It is fixed inside the oral cavity with the help of clasps and arches and usually sits on the jaw ridge without much difficulty. In contrast, a total denture is equipped with a large number of artificial teeth, and is usually made as soon as all teeth in one jaw (upper or lower jaw) have been lost.
Both the fabrication and the creation of an ideal hold within the oral cavity is much more complicated with a total prosthesis than with a partial prosthesis. The hold of such a prosthesis is largely created by so-called adhesion forces between the oral mucosa and the prosthesis material. Contrary to the widespread assumption that a total prosthesis finds a much worse hold in the upper jaw than in the lower jaw due to gravity, the reality is different.
Total dentures in the upper jaw usually have a larger surface area, which means that greater adhesive forces can be built up between the oral mucosa and the denture material. In addition to the accuracy during the fabrication of the removable denture, the hygienic handling of the device also plays a decisive role. Prostheses that are rarely cleaned and therefore show heavy deposits, generally find hardly any hold on the alveolar ridge.
How do I clean dentures with vinegar?
The denture can also be cleaned by the dentist or a dental technician by means of a professional denture cleaning. First of all, the soft plaque is removed by an ultrasonic or eddy current device. Then tartar and nicotine or tea impurities are removed by the device.
The ultrasound blasts the plaque off the prosthesis to a certain extent. For this purpose the prosthesis is placed in a water bath. The ultrasound causes the water bath to vibrate and small pressure waves are created which can be used to remove various plaque and tartar.
