Description

The utility model relates to medicine, namely to orthodontics and the section of early pediatric prosthetics - it can be used to prevent the development of deformations after early removal of temporary teeth as a replacement design, treat dentoalveolar anomalies and deformations of various etiologies, and eliminate bad habits during a temporary and mixed bite.

An apparatus of a similar design is the retention device proposed by Dr. Osamu Yoshil in 1980 (Persin L.S. Orthodontics. Treatment of dentofacial anomalies - M .: Scientific-Publishing House. Center "Engineer", 1998. - S. 266-267). The horseshoe-shaped orthodontic apparatus is located within the dental arch and part of the mucous membrane in the cervical region. The crown of the tooth to the alveolar process is covered with soft plastic BIOPLAST, which, in turn, together with the occlusal surface is covered with IMPRELON S. The only function of this design is the retention of the results achieved at the end of the active period of orthodontic treatment using the edgewise system. The disadvantages of this apparatus are the impossibility of manufacturing a double jaw mouthpiece, the lack of a therapeutic effect from exposure to the dentition, use only in the period of the formed permanent bite.

Known design proposed by Professor Dr. Hinz in 1982 a vestibular plate of MUPPY of various modifications (www.dr-hinz-dental.de.). The device is a standard made plate of hypoallergenic medical silicone filling the vestibular cavity. The device is manufactured in two sizes for a temporary and intermittent bite, marked with the corresponding color (with a red retaining ring for a temporary bite, with blue for a replacement bite). The vestibular plate MUPPY is used as an additional device in the process of speech therapy correction, eliminates the oral type of breathing, trains the circular muscle of the mouth, and can be used in combination with orthodontic appliances. The main disadvantages of this design are the lack of individualization of the size of the plate (standard manufacturing method), the absence of mechanically acting elements, age restrictions for use (temporary and first period of a replacement bite).

The closest prototype in design to the proposed device is a myofunctional apparatus from the TRAINER group proposed in 1989 by Professor Chris Farrell (Australia) and subsequently patented by the company "MYOFUNCTIONAL RESEARCH CO." (US Pat. US 5.624.257). Orthodontic constructions from this group are double-blended elastomers made of polyurstan and medical silicone as standard. TRAINER is used to eliminate bad habits and to treat abnormalities and deformations of the dentofacial system of various etiologies. Significant disadvantages of this design is: a template manufacturing method with a limited selection of sizes that do not cover the entire range of parameters of the patient's dentition; lack of the ability to repair and relocate the structure; the inability to individually transform the structural elements by the attending physician; difficulty in caring for a myofunctional trainer at home; high price of the device.

The technical result of the utility model is the creation of a device that allows for active preventive measures to eliminate the negative consequences after the early removal of temporary teeth and the simultaneous correction of existing anomalies and deformations of the dentition in children in the period of temporary and intermittent occlusion.

The transformable treatment-and-prophylactic elastic kappa consists of the following structural elements: pelot for the upper lip (1); the vestibular arch on the upper dentition (2); the vestibular arch to the lower dentition (3); pelot for the lower lip (4); cells for anterior teeth (5); buccal shield (6); lingual emphasis (7); cells for lateral teeth (8); base part (9).

The device can be conditionally divided into the base part, functional elements, mechanical elements.

The base part of the device includes an individually manufactured base made of soft plastic (9) covering the vestibular and oral surfaces of the crown of the teeth and adjacent to the mucous membrane of the alveolar processes (Fig. 1; Fig. 4).

The functional elements of the device are vestibular pelots for the upper (1) and lower (4) lips, designed to combat bad habits and stimulate the growth of the upper and lower apical bases in the anterior section (Fig. 1; Fig. 3). Functional elements include buccal shields (6), separating the muscles of the buccal region, and the lateral sections of the dentition stimulate the growth of the apical basis in the distal parts of the dentoalveolar complex (Fig. 2; Fig. 3; Fig. 4). Functional elements include lingual emphasis (7) deprogramming the position of the tongue from a pathological to a physiological state (Fig. 2; Fig. 3).

The fixation of the apparatus in the oral cavity is carried out due to the formation of multiple interocclusal contacts between the upper and lower dentition when the jaws are closed in the cells for the front teeth (5) and in the cells for the posterior teeth (8) of the elastic mouthguard (Fig. 2).

For the manufacture of a transformable treatment-and-prophylactic elastic mouthguard, an orthodontic wire made of TMA alloy with a cross section of 0.7-0.8 mm and soft elastic plastic "Bioplast" followed by polymerization in a vacuum polymer is used.

Kappa is made as follows. Impressions are taken from the upper and lower dentitions in a patient using a silicone mass. Working models of the upper and lower jaws are cast from super gypsum. The vestibular arches are bent and fitted for the upper and lower dentitions made of orthodontic wire with a TMA alloy with a cross section of 0.7-0.8 mm. The cross section of the wire is selected individually depending on the size by which the teeth need to be moved. The dental arches are strengthened on the vestibular surface of the models in the center of the clinical crowns of the teeth with sticky dental wax. Set the modeling platforms flush with the top edge of the modeling cup. Models are placed on the platform in the position of a structural bite and a round blank of Bioplast material 3.0 mm thick is applied to both jaw models. The plates are heated on the polymerization apparatus according to the instructions. The pressing chambers are closed and an automatic pressure supply of 5 atmospheres is performed for 15 minutes to clearly display the architectonics of the dentition and alveolar ridge. The chambers are opened after cooling and the extraction of dentition models with a transformable treatment-and-prophylactic elastic mouthguard. Fit and fix the device in the patient’s oral cavity, give tips on caring for the structure at home.

To activate the transformable treatment-and-prophylactic elastic mouthguard, using universal orthodontic forceps, apply shaping bends to the vestibular arch integrated into the vestibular surface of the apparatus for the upper dentition (2) and for the lower dentition (3), (Fig. 1; Fig. 3; figure 4). After that, the force generated by the vestibular arches is transmitted through the elastic layer of plastic to the moved teeth.

The advantages of the proposed transformable treatment-and-prophylactic elastic mouthguard are the manufacture of individual dentitions according to individual gypsum models, that is, a thorough conversion of the biometric parameters of the dental arches in the process of orthodontic treatment; active mechanical action on the moved teeth with the help of vestibularly spaced arches made of TMA alloy without periodontal overload; The materials used for the manufacture of the apparatus are hypoallergenic and non-toxic.

Kappa makes it possible to carry out active modeling of the relief of the apparatus base in conditions of clinical admission, it is easily superimposed and removed from the oral cavity, this is important in the treatment of patients in early childhood. The device has good aesthetics because the material is transparent. In the manufacturing technology, there is no modeling stage carried out by a dental technician, which reduces the cost of the apparatus. Hygienic care for the orthodontic design does not require special sterilization methods, it is possible at home.

Thus, the orthodontic device that we propose is a transformable treatment and prophylactic elastic mouthguard that contains new mechanically acting elements - tooth arches that allow you to transmit force without periodontal overload of the moved teeth due to the elastic layer of soft plastic. Therefore, the presented orthodontic device allows the correction of most dentoalveolar anomalies and deformities of various severity and origin and actively prevents the negative processes that accompany the early removal of temporary teeth in children. The introduction into clinical practice of a transformable treatment-and-prophylactic elastic mouthguard will make it possible to qualitatively increase the level of orthodontic care for children in preschool and early school age, while reducing the total time of the active treatment period and retention of the achieved results.
