Removable dental prosthesis

 

(57) Abstract:

The invention is intended for use in prosthetic dentistry in the manufacture of dentures. The technical result of the invention is to achieve accurate reproduction of macro - and micro-relief palatal surface. Denture contains interconnected artificial gums, teeth and telegathering basic element with limiter that allows you to play individual topography palatal arch and to ensure the rigidity of removable denture, and also creates comfort, quick to adapt and durability in use. 2 C.p. f-crystals, 3 ill.

The invention relates to the field of medicine and medical equipment and can be used in prosthetic dentistry.

From the state of prior art in this area is known for a removable dental prosthesis, in which the base is made of plastic. USSR author's certificate N 1722485, class A 61 C 13/03, 1990 Disadvantage basis of plastic is that it covers a significant portion of the mucous membrane of the oral cavity and thus reduce the receptor field. The mucous membrane under the prom violated taste, lost orientation in the definition of hot and cold.

Also known removable dental prosthesis with the basis of titanium alloy obtained by the method of casting on wax models. Rogozhnikov, I. and other Titanium casting in prosthetic dentistry Perm, LLP "Printing" Book", 1994.

The said base is made in such a way that does not allow a sufficiently accurate reproduction of macro - and micro-relief palatal surface.

Technical result achieved is the production of a removable dental prosthesis with the basis from titanium alloy that allows you to play individual topography palatal arch and at the same time to ensure the rigidity of the structure, as well as providing comfort, durability and rapid adaptation when using the prosthesis.

This is achieved by the fact that in removable dental prosthesis, consisting of interconnected base made of titanium alloy, artificial gums and teeth, the basis of the titanium alloy is made in the form telegathering basis element with a thickness that allows you to play individual topography palatal arch and to ensure the rigidity of removable denture, as well as the fact, and the inner side surface of the base perimeter, along the alveolar ridge, and a third on the inner side surface of the base around the perimeter along the line, as well As the fact that the first and second grooves are located one below the other or offset one relative to another in the horizontal plane of the base and also the fact that the clasps and the basis is made in the form telegathering basis of element.

In accordance with the invention a removable denture is a single structure in which the main bearing element is telegathering basic element to which are attached the artificial gums and teeth. The design of the denture shown in Fig. 1 - 3.

The term "telegathering element, in this case, refers to any element or the prosthesis is made from a single sheet of titanium alloy by gas forming in certain technological and technical conditions for use in orthopedics.

Mentioned telegathering basic element has any clinically shown to a thickness of, for example, 0.2 - 1.1 mm, which provides a detailed display of macro - and microstructure of the palatal arch on both sides telegathering basic element of the maintenance clasps.

Thus, the use of basis made in the form telegathering item from titanium alloy, removable dental prosthesis that gives the latter a distinct advantage over existing plastic and metal manufactured by a process of stamping or casting. Such advantage can be attributed to the following.

Biological compatibility, eliminating the possibility of allergic reaction that occurs in real time when using metal bases are made of alloys consisting of Nickel and chrome.

High strength and light weight of the prosthesis with sufficient rigidity to be achieved due to the high specific strength of titanium.

Exact reproduction of the individual topography of the palatal vault, which, in turn, ensures the preservation of the natural speech and taste.

1. Removable dental prosthesis, consisting of interconnected basis, made of titanium alloy, artificial gums and teeth, characterized in that the basis of the titanium alloy is made in the form telegathering basic element with thickness, which enables you to play is ratesa, and contains limiters, made in the form of grooves located: the first and second grooves on the outer and the inner side surface of the base around the perimeter, along the alveolar ridge, and a third on the inner side surface of the base around the perimeter, along the line A.

SUBSTANCE: method of forming elastic silicone substrate on rigid plastic basis consists in that mechanically and chemically treated surface of rigid basis adjusting to prosthetic bed is moistened with monomer being a member of basis plastic composition, dried, and coated with adhesive primer. After 1 min pause, basis is introduced for 3-4 min into microwave field emitted by source with power 450-600 W. After microwave treatment, surface is coated by cold-cured elastomer and substrate layer is then formed in mouth cavity. Adhesive strength of layer is thus increased by more than 1.5-2 times when compared to conventional method.

EFFECT: increased strength of bond between soft substrate and rigid plastic basis, and prolonged service time of denture.

SUBSTANCE: after obtaining of anatomical impressions from both jaws of the patient, the stage of central occlusion determination and models plugging into the occludator/articulator, artificial teeth setting is begun, taking into account the anthropometric indices. The wax structure of the prosthesis in the patient's oral cavity is checked. The wax is replaced by thermoplastic according to the manufacturer's instructions. At that, the basis of the removable prosthesis is reinforced, adding up to 1 wt % of nanostructured titanium dioxide in the form of a powder directly to the polyamide granules, evenly mixing it in the thermoplastic mass. The basis is made of polyamide structural material Vertex ThermoSens.

EFFECT: method allows to increase the effectiveness of orthopedic treatment with removable dentures due to improved strength and aesthetic characteristics, absence of residual monomer in the prosthesis basis construction material.

SUBSTANCE: method involves producing maxillary defect imprint, manufacturing its plaster model and modeling wax pattern of obturator prosthesis. The model is compressed with single basis wax layer. Recess is formed on the palatine part corresponding to defect shape. The basis and wax copy of artificial alveolar process is modeled and teeth setting is carried out. Plate is produced from basis wax as a cover closing the recess formed on the palatine part. The cover models the palatine fornix in which a hole of 10-15 mm large diameter is produced. The plate is fixed with wax on defect edges. The so modeled hollow obturator prosthesis is plastered into cuvette composed of two parts - bottom and cover. Model with obturator prosthesis in vertical position is plastered into lower cuvette part. Upper cuvette part is set and filled with liquid gypsum on vibrating table. Gypsum flows inside of obturator through an opening in palatine part. Metal wire loop is introduced into the obturator through an opening in wax plate. Wire diameter is 1.0-1.5 mm as large. The cuvette is hold to achieve full hardening of gypsum. The cuvette is opened after removing wax by applying evaporation method. Obturator model and upper cuvette part are filled with dough-like plastic. Both parts of the cuvette is joined and pressed in vertical direction using bench press. The plastic is polymerized. The prosthesis is removed from the cuvette. Gypsum and reinforcing wire are removed from the cuvette through the palatine part opening. The opening is closed with self-hardening plastic.
