The invention relates to medicine, namely to orthopedic dentistry, and can be used for carrying out the activities of individual hygiene in patients with postoperative defects of the upper jaw.

As a result of surgical intervention in the upper jaw for cancer diseases or injuries of different origin occurs the message of the oral cavity with the nasal cavity.

To distinguish these anatomical structures and restore chewing and rehearsaling functions in the dental practice of dental prosthetics prostheses with obturators. The prior art discloses a maxillary denture-obturator is made integrally and contains two functional elements: the base of the prosthesis with artificial teeth made of hard polyurethane and the obturator of elastic polyurethane. The lower border of the obturator firmly attached to the mucous fistula surgical field coated zones undercut regions and anatomical areas of retention. The obturator is fully repeats the postoperative defect and has the shape of a hollow Cup-shaped structure. The border of the obturator can have a different thickness and length. The surface of the obturator facing the cheeks, has a maximum height and a rounded end hour�ü, pressed against the bone structure of the upper border of the postoperative defect (Patent RF №2477103 from 10.03.2013).

Known dentoalveolar prosthesis-obturator having a base with artificial teeth and clasp with fixing elements made of rigid polyurethane. The obturator is hollow and has a frame made of rigid polyurethane, and the outer surface is made of soft polyurethane. The entire prosthesis is made by casting, including sections forming the outer boundaries of the surgical field. The technical result of the invention is the production of lightweight dentoalveolar prosthesis-obturator is made of polyurethane for high congruence of the base of the prosthesis to the prosthetic bed, especially along the border of the defect of the upper jaw, the lowest adhesion of microorganisms to denture-obturator and recovery phonetics patient, intelligible speech (Patent RF №2452431 from 10.06.2012).

Known dentoalveolar prosthesis-obturator having a metal base composed of a body, firmly attached to the lining of the saved hard palate, systems cast of clammers and a perforated plate located in the continuation of the hard palate and overlying the postoperative defect, fixed on her obturator is hollow and has a frame made of rigid polyurethane, and the outer surface of �and hard polyurethane, made in such a way that the outer surface of the obturator go to 2 mm for scar ring defect around its perimeter and retention points of 1 mm (Patent RF №2489115 dated 10.08.2013). All of these designs are final prosthesis and perform the main purpose of the recovery of the patient.

Patients with a history of cancer status, often arrive in a state of immunodeficiency that is associated with the specifics of the applied pharmacotherapy. This entails a change of microbiocenosis of the oral cavity and active formation on the borders of the prosthesis microbial biofilms is often represented by pathogenic microorganisms. The result is inflammation in the scar area of the ring and tissue bordering the prosthesis, resulting in a decrease of the retention properties of the prosthetic bed and patient dissatisfaction fixation and stabilization of the prosthesis. Recommended by experts daily antiseptic treatment of the oral mucosa and prosthetic bed involves the removal of the specified prosthesis, causing problems, primarily associated with the exposure of the message of the cavities of the mouth and nose and undesirable penetration of the disinfectant into the respiratory system.

The task, which directed the invention is the provision ol�management activities, personal hygiene in patients with postoperative defects of the jaws.

The technical result of the invention is to ensure separation between the cavities of the mouth and nose in patients with postoperative defect of the upper jaw during the execution of the procedures of individual hygiene. The technical result is achieved due to the fact that the device for carrying out the activities of individual hygiene in patients with postoperative defects of the jaws is made integrally of a soft polymer and has two surfaces and intraoral obturator, the obturator surface has the shape of a bowl, with a retention element of a width of 1-2 mm around the perimeter of the obturator portion of the prosthesis facing the nasal cavity, the boundaries of the outer diameter which exceeds the diameter of the fibrous ring (2-3 mm) and intraoral surface facing into the cavity, shaped to fit the hard palate of the patient and has on the outer surface of the ring.

This design is intended for the separation of the cavities of the mouth and nose in patients with postoperative defects of the jaws during the execution of the procedures of individual hygiene. The elasticity of the material of construction and design features, namely, that the boundaries of the outer diameter of the obturator portion exceeds the diameter of the fibrous ring (2-3 mm), allow to provide stable fixation of�already listed the device in the message area of the cavities of the mouth and nose during hygiene procedures. To facilitate retrieval of the device the outer surface has a ring to which it is possible to attach dental floss or any other supporting elements.

The design of the proposed device for carrying out the activities of individual hygiene in patients with postoperative defects of the jaws is illustrated by drawings, where Fig.1:

1. Occlusive surface of the device.

2. Retention elements on the perimeter of the occlusive portion of the device.

7. The nasal cavity.

8. The mouth.

The device for carrying out the activities of individual hygiene in patients with postoperative defects of the jaws is produced as follows.

The patient in the final stages of prosthetics (uses the final prosthesis obturator) receive impressions alginate mass and made working plaster model. On the model carry out the etching of the inner surface of cicatricial ring (6) from the side of the nasal cavity (7), 2-3 mm around the perimeter. Further, from wax model occlusive surface of the device (1), with retention elements (2) and borders on�ports of the outdoor diameter (3), passing through the previously etched inner surface of the scar ring. And also simulate the intraoral surface of the device (4) facing the patient's mouth (8), the ring (5) designed for ease of later retrieval of the device by the patient. Received wax design duplicate special dental mass and produce a device for carrying out the activities of individual hygiene in patients with postoperative defects of the jaws of soft polyurethane molding. The device is processed and priazovets in the oral cavity of the patient.
