SUBSTANCE: kappa applied for detection of parodentium and jaw bone tissute state is made of non-radiopaque flexible plastics and contain measuring element inside. Kappa is monolithic two-leaf isolated between dentures within first antagonistic molars, filled with plastics along isolation lengthwise. Measuring element is designed as graduated orthodontic wire and installed within kappa body in first antagonistic molars area. Within anterior teeth group inside of kappa body there is a cavity for attachment or strip rigidly mounted to orthopantomograph. Invention enables to provide accurate detection of bone tissues within first and subsequent X-ray examination (orthopantomogram, panoramic radiograph) with equally fixed position of jaws, increased efficiency of oral therapy.
EFFECT: improved objective diagnostics of facial bone state associated with oral therapy in dynamics under orthopantomogram results by means of simple device.
The invention relates to the field of medicine and medical technology and is intended for use in prosthetic dentistry when determining the state of the bone tissue of the alveolar process of the jaws in periodontal diseases, carrying out x-ray studies in identical (the position of the lower jaw).
The prior art clamshell Kappa that contains the basis of elastic material with a wire frame of the orthodontic wire made in the form of a single element having the shape of two arcs, the first of which corresponds to the dentition of the lower jaw from the lingual side, and the second corresponds to the dentition of the upper jaw with vestibular side, and the frame is made in the form of mover teeth, and the base has a mounting surface for positioning the teeth in occlusal contact and made of porous polymer (EN 2000123362/14, CL AS 7/36, publ. 2001.08.10).
Famous Kappa is intended for use in orthodontic dentistry and increases the effectiveness of treatment due to side effects in the application of the orthodontic apparatus of elastic plastic.
The prior art two-jaw mouth guard, made from monolithic elastic material with sockets for the teeth of the upper and lower rows, with Kappa realize who and shape of the alveolar processes of the jaws, has the jumper in the area of the bite and partially overlaps the hard palate. (U.S. Pat. Of the Russian Federation No. 2116767).
Famous Kappa is intended for the treatment of periodontal diseases by massage periodontal, mucosal gum and rubbing them in a medicinal product.
The prior art individual dental Kappa, on the surface where the fragments of the grid by means of a milling machine with the formation of the grooves, which are filled with the radiopaque substance for the review of radiography. Counting dimensions of the damaged bone tissue is performed according to the number of cells (EN 2134454, AS 7/36, publ. 20.02.2002).
The prior art dental radiolucent Kappa from an elastic material, including congruent with the contour of the gums radiopaque grid with a cell diameter of 1 mm (EN 2215810, AS 7/36, publ. 10.02.2005).
The last known disadvantages of Invisalign is a rather complicated method of detecting bone lesions, requiring time-consuming mathematical calculations.
Task to be solved by the claimed invention is directed, is the creation of devices that facilitate the accurate determination of the status of bone tissue in primary and repeated x-ray studies (orthopantomography, panoramic radiography) in the same fixed position, Celeste is when each study.
The technical result of the invention consists in the improvement of objective diagnostics of facial bones in the treatment of diseases of the maxillofacial area in the dynamics according to orthopantomogram using a simple device.
The technical result is achieved due to the fact that Kappa to determine the status of periodontal and bone tissues of the jaws, made of non-radio-opaque flexible plastic and contains a measuring element inside, molded in one piece clamshell with a separation between the tooth rows in the first anthonious molars, filled plastic all over disjunction, while the measuring element is designed in the form of orthodontic wire with divisions and installed in the body of the mouthguard in the first anthonious molars and anterior teeth in the body of the mouthguard made cavity under the fixture or the bar, rigidly connected with orthopantomography.
The invention is illustrated in the drawing.
Clamshell Kappa 1 is made of elastic non-radio-opaque plastic. The separation between the tooth rows is 3 mm in the first anthonious molars, filled with plastic during the disconnection. In the body of the two-jaw mouthguard in the first anthonious molars installed measuring elements 2, and is made from segments of orthodontic wire length of 10 mm, which is applied to risks (division) in 1 mm In the anterior teeth in the body of the two-jaw mouthguard made cavity 3 for its fixation on the orthopantomograph.
Two-jaw mouthguard is made individually for each patient as follows.
After hygienic treatment of the teeth of the upper and lower jaws removed the prints for the production of models of super plasters. In the dental laboratory are made on models of super plasters using a vacuum apparatus clamshell Kappa with a separation between the tooth rows in the first anthonious molars in 3 mm. After that, leaving two-jaw mouthguard on models with the vestibular surface of the stack segments orthodontic wire, for example a length of 10 mm, which is applied to risks (division) 1 mm, Then using a vacuum apparatus punched another two-jaw mouthguard with measuring elements, then remove it from the model. The cavity for fixing on the orthopantomograph perform mechanically.
Two-jaw mouthguard is used as follows.
To obtain reliable information about the condition of the periodontium should be made about six x-rays. With each subsequent shot, there is a natural offset of the patient's head relative to the locking device orthopantomograph that echet a distortion of information about the previous state of periodontal and bone tissues. To eliminate this factor it is necessary to fix the patient's head in the same position for each subsequent image in cephalostat. Made individually for each patient according to the above-described technology two-jaw mouthguard is installed in the oral cavity and fixed the position of the upper and lower jaws. Then, in the cavity for fixing on the orthopantomograph available in clamshell cappagh, insert the bar from orthopantomograph and take a picture of the traditional method.
