Removable laminar denture

 

(57) Abstract:

The invention can be used in the clinic of orthopedic dentistry in the manufacture of prostheses and devices to restore lost teeth, mastication, articulation, speech. The technical result - the increase adhesion of the prosthesis and the improved condition of the mucous membrane of prosthetic bed. This objective is achieved in that the elastic layer basis along with the plasticizer made from 0.07 to 2.1 ml balm of Shestakovskaja. Offer removable double-layer prosthesis reduces the intensity of the flow of atrophic processes of tissue prosthetic bed due to the presence of long-antiseptic, anti-inflammatory effect due to the elastic layer containing Vinylinum, a significant decrease in the amount of plasticizer and accurate representation of the relief of the mucous membrane. Removable laminar denture composed of an acrylic base, which is fixed artificial teeth, and soft elastic plastic. table 1.

The invention relates to medicine, namely to the field of prosthetic dentistry, and can be used in the clinic of orthopedic dentistry in the manufacture of prostheses and devices of the prosthesis, containing two-layer basis for optimal pressure distribution of the prosthesis to tissue prosthetic bed consisting of acrylic basis on which artificial teeth are attached, and the soft lining of elastic plastic facing to the lining of the prosthetic bed. (Kalinina N. In., Zagorski Century A. restoration with complete loss of teeth. M.: Medicine, 1990. - S. 182-185.)

The disadvantages of the above are similar lack of antimicrobial and anti-allergic properties in implants made from these compositions.

Known removable two-layer laminar dentures consisting of acrylic base and artificial teeth, an elastic film containing antifungal drug. The prosthesis also equipped with additional equipment limit of the film thickness. (A. S. N 160075 class. A 61 C 13/00, 1990).

Removable laminar denture is manufactured as follows. After removal of the anatomical impression with toothless jaws cast model, which compresses one or two layers of clasp wax depending on the desired film thickness. After that, the diameter of the planned stops the thickness of the polyurethane film with a scalpel cut clasp wax. The surface of the clasp is re-crimped single layer bugelnogo wax, moreover, in the area of the limiting film thickness it should prodavatsa to the plaster model. The thus prepared outer wax base is separated from the inner and gypsum into the cell to replace the wax on quick hardening plastic. Ready hard plastic spoon basis fully reflects the topography of the prosthetic bed, but with the inner surface has a space corresponding to the thickness of the pre-pressed clasp wax, and protruding above the level of the basis of the limiting thickness of the polyurethane film. After it was made from a model shoot pressed the clasp wax and placed on the inner surface. The obtained spoon basis set bite the platen and define the Central occlusion and produce the production of artificial plastic teeth, preferably on a solid wax. Conduct design verification removable laminar denture, functional design of its borders and edges of the valve zone thermoplastic mass. Then with the inner surface of the spoon basis remove the clasp wax, gypsum cell in the reverse way and replace the spoon with functionally decorated edges on the base material according to the usual method by polymerization, in the key basis ie has the space and limiting the film thickness, the prosthesis is polished and polished. In the clinic on the inner surface of the prosthesis is applied in a very thin layer select or Repin, the prosthesis is mounted on the prosthetic bed in the position of Central occlusion and is the final receipt of correcting functional imprint repetition of functional tests. Dentures with dental impression hipoteca cell in the reverse way. After the final curing of the plaster of the cell open, removed the dental impression material. The plaster surface contrastano isolated by izokol and dried until complete dehydration of gypsum, the inner surface of the prosthetic base thoroughly degreased, is applied a mixture of polyurethane prepolymer with antifungal medication, are mapped to the two halves of the cell and pressed. After 48 hours, the prosthesis is removed from the cell and removed the excess polyurethane. The result is removable laminar denture having a layer of elastic polyurethane film is equal to a specified thickness clasp wax.

The disadvantage of these prostheses is a violation of adhesion and limit use of the medicinal substances with lower doses, but more expozitiei shell prosthetic bed.

This objective is achieved in that the elastic layer basis along with the plasticizer is made from 0.07 to 2.1 ml balm of Shestakovskaja. Experimentally we have selected this number (0,07 - 2,1) balsam, in which the properties of plastics are not changed for the worse, and therapeutic effect is improved.

Balm of Shestakovskaja (Vinylinum) is a drug which has strong antiseptic, anti-inflammatory and wound-healing effect. Vinylinum in medicine widely used to treat stomach ulcers. In dentistry it is used for the treatment of stomatitis (Busygin M. C. Diseases of the teeth and the mucous membranes of the oral cavity. - M, Medicine, S. 267-268).

Preparation of elastic bases of plastics PM-01 modified Vinylinum, conducted according to the standard technique. Took 10 g of the powder (copolymer, PVC) to which was added 7-9 ml of liquid in the form of a 1% solution of Vinylinum in dibutylphthalate, then thoroughly mixed until a homogeneous mass. Then made a double-layer prosthesis with a simultaneous package modified plastics PM-01 and basic plastics in a pasty state. The cuvette was placed in a thermostat and within 1.5 hours the temperature was raised to 100oAnd stress at break (R), relative elongation (%) were conducted by the method GOST 11262-68 on the machine type 2038 p-0,05.

The test for determining surface hardness (NSH) conducted a shore a Durometer TSM-2 according to GOST 263-75.

Determination of elasticity at bounce (But) was performed on progamer brand Rauenstein.

Physico-mechanical properties of modified compositions are given in the table.

Offer removable double-layer prosthesis reduces the intensity of the flow of atrophic processes of tissue prosthetic bed due to the presence of long-antiseptic, anti-inflammatory effect due to the elastic layer containing Vinylinum, a significant decrease in the amount of plasticizer and accurate representation of the relief of the mucous membrane.

Removable laminar denture containing two-layer base with an inner layer of an elastic polymer, comprising the drug, and the outer layer with artificial teeth, wherein the inner layer is made of elastic plastics PM-01, which introduced the drug Vinylinum from 0.07 to 2.1 ml to ensure long-term therapeutic action on the mucous membrane of the oral cavity.
