The invention relates to medicine, namely to prosthetic dentistry, in particular, to the manufacture of tyuleniy hard basis of dentures made of acrylic plastic, in particular polymethyl methacrylate, almost never achieved 100% polymerization. And methyl ester of methacrylic acid monomer, in principle, is a poison. For skin and mucous membrane of the oral cavity monomer is a strong irritant, which rapidly inhibits protective barriers that cause dental-patie patients. To avoid toxic - allergic effect of monomer on the mucous membrane of the mouth, on the inner surface of the prosthetic base is applied a protective layer of varnish (see A. C. 1688863 the USSR, MKI5And 61 With 13/09) or metal (see A. C. 1680142 the USSR, MKI5AND 61 WITH 13/02).To prevent bad smell from the mouth, tooth or prosthetic device fixed minemast with aromatic substance or refreshing (see patent 2127094 RF, MPK6AND 61 WITH 13/00).To improve the fixation of the prosthesis, redistribution of masticatory load during function, reduce the period of adaptation to the prosthesis, as well as to obtain a massage effect on the inner surface of the prosthetic base put elastic layer with rectangular tabs on the entire surface, not reaching edge 3-5mm (see patent 2112458 RF, MPK6AND 61 WITH 13/00, 13/07).Treatment of gum disease and SL is and.Counterparts, the purpose and description of the invention.A device containing a removable dental prosthesis and a reservoir with a capillary-porous material impregnated with a substance having an aromatic or refreshing effect (see patent 2127094 RF, MPK6AND 61 WITH 13/00).The device has the following disadvantages: finding capacity outside of the prosthesis leads to the inconvenience of its use; there is a possibility of getting the vessel into the esophagus or throat of a person, there is no opportunity to provide healing and antiseptic effect on the mucous membrane of the mouth.Closest to the proposed polyfunctional complete removable dental prosthesis in essential features for a prosthesis (see patent 2132661 RF, MPK6And 61 With 13/06), which contains a capillary-porous metal layer coated on one side with an elastic layer, a hard acrylic base denture with artificial teeth, located on the opposite side.This prosthesis has the following drawback: there is no opportunity to provide healing and antiseptic effect on the mucous membrane of the mouth and prevent bad breath.Isock mouth, security prevent unpleasant mouth odor.This task is achieved by the fact that in removable dental prosthesis containing capillary - porous metal layer coated on one side with an elastic layer, a hard acrylic base denture with artificial teeth, located on the opposite side, hard acrylic base denture connected with capillary - porous metal layer through the insulating layer, in capillary - porous metal layer are cumulative cavity on the outer surface of the hard acrylic denture bases located electrical contact element connected to the capillary - porous metal layer, the elastic layer is made of a capillary - porous with numerous capillary - porous protrusions on the outer surface, the average pore size of the elastic layer is less than the average pore size of the metal layer.Introduction to the design of the prosthesis of the insulating layer is needed. to the monomer of the hard acrylic denture bases did not penetrate through the capillary - porous metal layer and capillary-porous elastic layer and had no toxic or allergic effects on the mucous membrane of the mouth Palast is iPhone in chloroform on the metal layer after the filling of the pores with water.Introduction in capillary - porous metal layer cumulative cavities it is necessary to increase the amount of, for example, a liquid medication, cumulative in the prosthesis. This can be accomplished, for example, as follows: plasma spraying capillary-porous metal layer of titanium is performed in two stages; after the first stage, the coating layer include particles of sodium chloride to produce the second phase deposition; expanded water through capillary - porous metal layer, the sodium chloride dissolves in water and is removed from the metal layer. Another option: after the first stage of deposition, the deposited layer have a concave mesh elements from titanium concave surface to the deposited layer. The thickness of the metal layer may be, for example, 400. The average cumulative size of the cavities may be, for example, 150 MCR.The execution of the elastic layer of the capillary - porous, it is necessary to: liquid medication or flavoring solution became possible to upload in capillary - porous metal layer using electroosmotic effect; to enter the liquid medication from the prosthesis to the mucous membrane of the oral cavity in Procer may be, for example, 10 μm.Introduction to design electrical contact element is needed in order to be able to use electroosmotic pressure, after application to the electric contact element of positive or negative potential from the DC source. In the case of application to the electric contact element of positive potential, and the mucosa of the oral cavity is a negative potential, which significantly increases the yield of liquid medication from the prosthesis to the mucous membrane of the oral cavity. The larger the potential difference, the greater the flow rate of the medication. For the implementation of the electroosmotic effect in the prosthesis enough as a constant current source, to use the standard item power supply (battery) voltage from 1.2 to 3.6 V.The running average pore size elastic layer is less than the average pore size of the metal layer, it is necessary to ensure that under the influence of capillary forces were samosatene, for example, a liquid medication from the prosthesis to the mucous membrane of the oral cavity. Speed samosatene medication depends on the size of the pores of the elastic layer, and the ratio of pore sizes elastic and the Fig.2B - options for connecting the prosthesis to the source of electric current. Thus: 1 - hard acrylic base denture; 2 - insulation layer; 3 - capillary - porous metal layer; 4 - capillary - porous elastic layer; 5 - cumulative cavity; 6 - electric contact element; 7 - capillary - porous protrusions capillary - porous elastic layer 4; 8 - the surface of the oral cavity; 9 - DC electric current; 10 - a piece of the prosthesis; 11 - solution medication or flavoring substances.The construction of removable dental prosthesis consists of series-connected hard acrylic denture bases 1 with artificial teeth (conventionally not shown), the insulating layer 2, the capillary - porous metal layer 3, the capillary - porous elastic layer 4. Capillary - porous metal layer 3 contains the cumulative cavity 5 and is connected to the electric contact element 6 extending to the outer surface of the hard acrylic denture bases 1. Capillary - porous elastic layer 4 has a capillary - porous protrusions 7.The method of application of the proposed multifunctional full removable denture is as follows.To contact element 6 of the prosthesis is carstvo or flavouring substances, dipped positive output of the DC electric current 9 (see Fig.2A). As a result of osmotic and electroosmotic forces is accelerated filling solution, for example, drugs long capillary - porous metal layer 3, the capillary - porous elastic layer 4, the capillary - porous protrusions 7 and cumulative cavities 5.Further, the prosthesis appropriately fixed in the oral cavity. In the result of samosatene, medication or flavoring substance evenly over the area and gradually allocated to the mucous membrane of the oral cavity associated with the prosthesis. To accelerate the expiration of the medication or flavoring substance, a source of direct electric current 9 is connected according to Fig.2B. Increasing or decreasing the output voltage of the DC electric current 9, accelerate or decelerate the expiration of medication or flavoring substances from the prosthesis.To accelerate the expiration of the medication or aromatize-regulating substances, without the use of a source of direct electric current 9, it is enough to perform the chewing motion of the jaws. When the compression jaws capillary - porous protrusions 7 are included in kisitu the second layer 4 with capillary porous protrusions 7 and the mucous membrane of the oral cavity 8 and a region of low pressure. This reduced pressure causes the acceleration of the process of expiry of drugs.To stop the output of the prosthesis drug solution on the mucous membrane of the oral cavity, it is necessary to change the polarity of Fig.2B connect to the DC source.The advantages of the proposed design of the prosthesis allows: - to use the internal structure of the prosthesis as the battery medicinal or flavoring solution; - uniformly to influence a medical solution to the mucous membrane, coupled with the prosthesis; - to periodically fill the internal structure of the prosthesis medicinal or flavoring solution; - to increase the output of the prosthesis medicinal or flavoring solution to the mucous membrane of the oral cavity when performing chewing movements of the jaw; - to further increase the output of the prosthesis drug solution on the mucous membrane of the oral cavity when connected to the constant current source; - to stop the output of the prosthesis drug solution on the mucous membrane of the oral cavity after connection to the power constant is m voltage DC source.In addition, the proposed design of the prosthesis provides such well-known functions such as: - protection of the oral cavity from the exit of the prosthesis methyl ester of methacrylic acid; - improving the fixation of the prosthesis;
- uniform redistribution of the masticatory load on the prosthetic bed;
- noninvasive condition in areas of atrophic mucosa covering torus, exostosis and bony prominences;
- getting a massage effect when performing chewing movements of the jaw;
- obtaining a complex of positive factors that improve the trophic tissue prosthetic bed and deceleration of atrophic processes in the jaws, especially in the areas of active osteogenesis.- improved durability of the prosthesis;
- reduction of the adaptation period for the patient.
