Description

TECHNICAL FIELD The present invention relates to a functional intraoral attachment device provided with functions such as promotion of biological function activation.

  Many studies have reported that chewing has various effects on biological functions such as promotion of metabolism, suppression of increase in blood sugar level, and increase in cerebral blood flow and alpha wave. It is also expected to be effective in disease prevention. (Non-Patent Documents 1, 2, 3)

  There are certain dental care applications for intraoral devices and mouthpieces, mouthguards, splints, etc. for sports.

Preventing metabolic by chewing Possibilities of dentistry from chewing. Japanese Dental Review 2008; 68 (6) 61-67

  The health benefits of chewing have been demonstrated in research. However, these results were obtained from the use of gum-based foods and wax fragments for research purposes, and increased daily intake and calories, and The elderly have problems such as aspiration and denture adhesion.

  Conventionally, an intraoral wearing device called a mouthpiece, a mouth guard, a splint (for example, Japanese Patent Application Laid-Open No. 2011-135903, Japanese Patent Application Laid-Open No. 2014-14499, etc.) is used to prevent disorders during exercise, and to provide dental treatment including sleep apnea. It is intended for medical use, and its material is hard and not suitable for "chewing", and there is no consideration for chewing even in morphology, and it itself has a function of promoting general health and activation of biological functions. Not what I expected.

The elasticity of the soft resin-based material used for an intraoral mounting device generally called a mouthpiece, a mouth guard, a splint (for example, Japanese Patent Application Laid-Open No. 2011-135903, Japanese Patent Application Laid-Open No. 2014-14499, etc.) 2.39 (N / mm ² ) or more and low in viscosity. Further, among the silicon-based materials that can be used as other materials in the oral cavity, even the softest material at present has an elastic modulus of 4.34 (N / mm ² ), and it is difficult to adjust the compounding ratio. It does not have moderate viscosity.

  The present invention has a soft and moderate elasticity to an intraoral wearing device, has a texture and viscosity close to food, and has an optimal hardness, thickness and shape for chewing, and aims to promote activation of biological functions by chewing. The purpose of the present invention is to realize a functional intraoral mounting device with a new concept.

In order to achieve the above object, the functional oral cavity of the present invention is composed of a molar occlusal surface, a molar occlusal surface outer edge, an outer wing, an anterior labial incisal covering portion, a molar inner side edge, and an inner wing. The form of the internal mounting device was based on the lower jaw, and the molding was performed according to the dentition of the individual, and the occlusal surface of the molar was provided with a bite of constant thickness (3 ± 2 mm) that was optimal for mastication.

Secondly, the material used is a dental heat-curable soft type resin. By adjusting the compounding ratio, an elasticity coefficient of about 1.89 (N / mm ² ) and an elasticity comparable to that of food gummy are realized, and The adjustment of the biting comfort which has moderate elasticity and viscosity in the range of ± 10% is enabled.

  By realizing the above two items, the effect that the intraoral wearing device has a moderate elasticity and viscosity and softness due to biting margin and has a feeling and texture close to food can be obtained. It is possible to activate such biological functions.

1) consists Posterior occlusal and the molar outer side edge and the outer wing and anterior cover portion and the posterior portion inner edge and the inner blade, with optimal elasticity, thickness and formation to chewing and feel close to the food The soft and viscous intraoral mounting device enables chewing without discomfort and burden on the oral cavity and the temporomandibular joint, and is used to prevent lifestyle-related diseases and dementia by promoting activation of general health and biological functions. It is effective.
2) The above-mentioned effect can be achieved by using a soft resin as a material to be used, an elastic coefficient of about 1.89 ± 10% N / mm ² and a thickness of 3 ± 2 mm.
3) By adding the front teeth of the lower dentition, it is possible to attach more firmly.

FIG. 1 is an external view of an intraoral mounting device showing an embodiment of the present invention.

Hereinafter, an embodiment of the present invention will be described with reference to FIG.

Functional oral mounting device is a soft type resin, one that can be adjusted in a range of ± 10% in elastic modulus of about 1.89N / mm ^2, the occlusal surface of the switching edge contact and molar teeth of the lower jaw dentition anterior They are respectively formed anterior incisal covering portion and posterior occlusal surface so as to cover the outer blade formed by extending wing to molars outer side edge or we lower is shorter in height as much as possible To connect to the labial covering of the front teeth. The inner wing extending wing to whether we lower molars inner edge is along the teeth while covered crowns lingual surface of the tooth.
This form contributes to the stability of the device during use, especially by setting the thickness as 3 ± 2 mm as the bite margin given to the occlusal surface of the posterior part, without discomfort and burden on the oral cavity and temporomandibular joint Made it possible to chew. The nature of the material also allows the device to fit well in the oral cavity and be used without damaging the oral mucosa.
Biological functions such as activation of the sympathetic nerve and brown fat cells by chewing and chewing mainly by these, and promotion of metabolism, suppression of blood sugar rise and promotion of brain functions such as cerebral blood flow and alpha wave Activation and health promotion effects became possible. In other words, its functionality can be applied to diet programs, lifestyle-related diseases, and dementia prevention programs. Using functions such as concentration and relaxation by increasing cerebral blood flow and alpha waves, it is possible to improve the performance in athletes and other environments that require concentration and to prevent drivers from falling asleep. thing. By chewing, it promotes the strengthening of various muscles forming the oral cavity and can be used for oral rehabilitation for healthy chewing ability and reinforcement of swallowing function. The ability to chew the oral muscles and the tongue motors by strengthening the chewing movements, enhance the lip pressure and tongue pressure that decrease with aging, and improve pronunciation and vocal function. In addition, the chewing operation gives an appropriate stimulus to the oral muscles and various facial muscles, which is effective for face lift-up from an aesthetic and esthetic dental viewpoint.
