Method for producing treatment-and-prophylaxis dentogingival splint

FIELD: medical engineering.

SUBSTANCE: device has vestibular and oral parts connected to each other with crosspieces manufactured from orthodontic wire placed in interdental spaces by producing jaw imprints. Working and auxiliary models are molded. To place treating bandage, general clinical equator of all teeth included into the splint is to be determined on working model using parallelometer. Then, space between the clinical equator line and gingiva and a gingiva part 7-8 mm remote from gingival papillae are covered with dental wax layer of thickness equal to or less than 1.5 mm. Next to it, duplicate model is produced for manufacturing the splint having recess equal to wax layer thickness 1.5 mm. Changing wax for transparent plastic, filing and polishing the splint is carried out by applying method of common use.

EFFECT: enhanced effectiveness of treatment.

Region. The invention relates to medicine, namely to prosthetic dentistry and Periodontology, and can be used for the manufacture of medical-preventive dental-gum tires for the treatment of periodontal diseases.

Analogues. Currently using a method of creating a “depot” of drugs fabrication of aligners made of thermoplastic materials (Thegrusom, Glavin// Dentistry. - 1987. No. 2. - P.70).

Criticism analogues. Kappa manufactured in a known manner, interfere with occlusal contacts, which can lead to aggravation of pathological processes in periodontal tissues. "Depot" is created only from the vestibular side.

The prototype. The prototype is a method of manufacturing a dental retainer removable splints Weber for the treatment of fractures of the jaw (Lieselotte “Prosthodontic equipment and materials science, Moscow. - “Medicine”. - 1966. - S-362). For the manufacture of such tires, the authors removed the casts of the upper and lower jaws and cast models that capture occludator in the position of Central occlusion. In order to strengthen the tire and prevent it from sinking into the mucous membrane during chewing on the model of the closed curve the wire frame (arc) stainless steel with a diameter of 0.7-0.9 mm. On the prototype frame Flex so that between him and gypsum C shall apply to the distance of 0.75 mm. Outer and inner arc of the frame connect the wires that come in the form of a toggle clasps, i.e. at the proximal contact points of the teeth, choosing the most advantageous sites for the wire does not interfere with the teeth - antagonists. Wires connecting the outer and inner arc of the frame, protect it from breaking during use of the tire. Then simulate wax outer and inner surface, leaving exposed cutting edges and occlusal surfaces of the teeth. Simulated bus gypsum and end up as a removable prosthesis.

Criticism of the prototype. The existing method does not establish a “depot” of drugs.

The purpose of the invention. The aim of the invention is to improve the efficiency of complex treatment of periodontal diseases by including in the complex of therapeutic measures proposed bus.

The invention is illustrated figure 1 and figure 2

The invention and its distinguishing from the prototype signs.

This objective is achieved in that with the jaws removed the casts and cast working and auxiliary models. On a working model using a template identify common clinical equator all teeth included in the tire (1). The space between the line clinical equator and gum (retention area), and part of the gums at a distance of 7-8 mm from the de is nevah papilla is covered with a layer of wax thickness up to 1.5 mm (2). Wax is applied to eliminate the retention and creation of space for future bus to accommodate the medical bandage. Then the model grease compensation varnish and make a mold, which is prepared duplicate the model (3). On this model, mark the limit of the tires and the location of the jumpers. The jumper is made from orthodontic wire diameter 0.6-0.8 mm so that they had to interdental spaces and does not interfere with the gnashing of teeth (b). On the bus for the entire dentition enough 7-8 jumper. Once the plastic dental wax model of oral and vestibular part of the bus and put the jumper so that their free ends were fixed in wax in both parts of the bus (a, b). Replacement wax on transparent plastic, grinding and polishing tires produce conventional method (4).

In the clinic bus prepassivate in the mouth, then fit the medical bandage and the bandage is tire on a 1-3 day (s). Then the tire is removed, and after changing bandages worn again. Thus, the tire is to be used before the end of the course of treatment and can be saved for re-treatment measures. The principal difference of the proposed method against known is the fact that the space between the line clinical equator and gum (retention area), and h is b at a distance of 7-8 mm from the dental papilla is covered with a layer of wax thickness up to 1.5 mm, model grease compensation varnish and make a mold, which serves duplicate a working model.

A specific example. Patient F. 56 years (MK No. 01190121) came to the clinic complaining of bleeding gums, loose teeth, pus from periodontal pockets. At the examination: bleeding gums, subgingival deposits of stone and plaque, mobility

II degree, the presence of periodontal pockets with depth up to 4 mm in the field

Periodontal indices (HE I-S - 2,7; P I-I R 3,7-3,5) indicate the presence of destructive changes, characteristic for the second stage of the disease. Diagnosis: generalized periodontitis of moderate severity. Within 10 days the patient was a complex therapy with the inclusion of treatment-and-prophylactic tooth-gum tires on the lower jaw with the medical extemporally antibacterial bandage consisting of a 0.01% aqueous solution immunomoduliruushimi antiseptic Miramistin, mixed dental volosataya calcium cement for temporary fixation “Orthofix - Aqua” (the rat. th. No. 00-1114). After 5 days of splint disappeared gingival bleeding, gingival papillae compacted, stopped gnetaceae. By the end of treatment, liquider the Vanir periodontal pockets, tooth mobility is not observed. Periodontal indices within the normal range.

The effectiveness of the present invention. The method allows to produce a treatment and prevention of periodontal bus for the integrated treatment of periodontal disease, which increases the effectiveness of the treatment.

A method of manufacturing a therapeutic and preventive periodontal splints, made of vestibular and oral parts, connected by a jumper from orthodontic wire, located in the interdental spaces, by taking casts of the jaws and casting the working and auxiliary models, characterized in that to accommodate the medical bandage previously on the working model with parallelomania identify common clinical equator all teeth included in the tire, then the space between the line clinical equator and gums, as well as part of gum at a distance of 7-8 mm from the gingival papilla is covered with a layer of dental wax thickness up to 1.5 mm, then according to this model receive duplicate model, which serves bus with the notch on the thickness of the wax 1.5 mm, and the replacement of wax on a transparent plastic, and polishing bus conduct conventional method.
