Prosthetics on implants with partial absence of teeth is carried out only by fixed structures - crowns and bridges. However, in the absence of teeth (in addition to prosthetics with fixed bridges), there is a variant of conditionally removable prosthetics. The latter option implies that implants are placed under a removable denture to improve its fixation to the edentulous jaw.
The removable prosthesis Acre fries is a new type of prosthetics with partial and complete absence of teeth. These prostheses are made from a special type of acrylic plastic that does not contain monomer. Acry-free ® prosthetics was developed by "Perflex Ltd" (Israel). On Acre free prostheses, patient reviews are as follows: patients note less weight and volume of the prostheses, their hypoallergenicity, invisibility in the oral cavity, and moderate flexibility that is comfortable to wear.
Removable micro prostheses for 1-2 teeth are sometimes used for prosthetic dentition defects of a small size (Fig. 1). Such micro prostheses are termed the butterfly prosthesis. Such a term is probably used because the klammer of a micro-prosthesis (with the help of which it is fixed to the adjacent teeth) resembles the wings of a butterfly.
Corega (Corega ®) is available in the form of a cream and in the form of tablets. The cream is designed to improve the fixation of removable dentures, and the form in the form of tablets - for cleaning dentures from dirt. This article will allow you to decide on the choice of tools of this type. The Corega ® brand is owned by the English pharmaceutical company GlaxoSklein (GSK), which is one of the most famous pharmaceutical companies in the world.
Conditionally removable (covering) dentures are used mainly in the absence of teeth. These prostheses are securely fixed on the jaws - thanks to several implants installed under the prosthesis. Such prostheses are attached to implants with the help of special locking fasteners of push-button or beam type (Fig.
In most cases, patients do not properly care for their dentures, which very quickly leads them into disrepair. For example, out of habit, you can start brushing your denture with a regular toothpaste and brush, which will lead to the appearance of small scratches on the denture. As a result, the surface of the prosthesis becomes rough, and therefore plaque begins to be deposited on it very quickly, plaque, pigment spots appear, and the prosthesis begins to smell badly.
Under removable dentures is understood such dentures that the patient can remove and put on himself. As a rule, they are made only with a large number of missing teeth - in cases where there is no possibility of permanent prosthetics with bridges or through implantation of teeth.
Nylon prostheses began to be widely used about 10-15 years ago - as an alternative to traditional removable prostheses made of acrylic plastic. Prostheses from light translucent pink nylon are really much more aesthetic than both plastic and bugel prostheses. Also one of the main characteristics of prostheses made of nylon is their flexibility (elasticity).
Clasp prostheses today are the most effective type of prosthetics with partial absence of teeth. Best of all other types of dentures, they compensate for the lost chewing effectiveness, they are well fixed on the teeth, they are convenient for chewing and talking, they have a long service life. Clasp prostheses can be made only in those patients who have partially preserved their own strong teeth, and these teeth should be on both sides of the jaw.
Prosthetics in dentistry can be removable and non-removable. Fixed dental prosthetics are most often carried out with artificial crowns or bridges, which are securely fixed to abutment teeth or implants ground under crowns. Prosthetics in the absence of teeth or in the absence of a large number of them is often removable.
Silicone dentures are sometimes called dentures with a certain degree of flexibility. In fact, these prostheses have nothing to do with silicone, but they are made from other elastic materials, either nylon or AcryFree (Acrifri). The main advantage of prostheses from these materials is their amazing aesthetics, and they are not without reason called "prostheses invisible."
Nylon dentures differ from other types of dentures with two characteristics.First, they use translucent pink nylon as the base material, which also has elasticity (the latter gives the denture a certain degree of softness and flexibility). Secondly, such prostheses are fixed with the help of elastic clasps, also made of pink nylon, which makes them invisible against the background of the gingival mucosa.
Byugelny prosthesis got its name from the German word "byugel" - arc. Accordingly, this type of removable dentures will differ from dentures made from nylon and plastic dentures in that there will be a cast metal frame inside the denture (Fig. 1). The frame of durable metal can significantly reduce the volume and thickness of the base of the removable denture.
