Detailed Description
The present application will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the present application, but are not intended to limit the application in any way. It should be noted that variations and modifications could be made by those skilled in the art without departing from the inventive concept. These are all within the scope of the present application.
The inventor of the application finds that the design of the bite plate in the related art is not reasonable, when the bite plate is used for wearing, the bite plate bears larger acting force in the opening and closing process, the bite plate is easy to break or crack, and the service life of the bite plate is seriously shortened.
In view of this, and referring to fig. 1-3, the present application provides a bite training device 110 for bite plate treatment, so that the bite plate 111 can meet different bending requirements during bite treatment while guaranteeing the bite treatment requirements, reduce the possibility of breakage or cracking of the bite plate 111, and prolong the service life of the bite plate 111.
Example 1
The embodiment discloses a dental training device 110, including a bite plate 111, the bite plate 111 includes a cavity for holding at least one tooth, the bite plate 111 is an elastic plate body, and the bite plate 111 is made of an elastic material.
When the bite training device in this embodiment is used, when the bite plate 111 is worn on teeth, the teeth of a user are located in the cavity, the bite plate 111 is made of elastic materials, the bite plate 111 can well achieve bending buffering by means of self elasticity, a small amount of bending needed by the user is provided, physiological movement requirements of the user are well matched, the possibility that the bite plate 111 is broken or cracks are formed is greatly reduced, the service life of the bite plate 111 is effectively prolonged, and the cost performance and market competitiveness of the bite plate 111 are improved. In addition, because the elastic material is soft to touch, the toothbrush can be matched with dentin better, the toothbrush has good mechanical compatibility with dentin, the wearing experience of a user is improved, and the possibility of uncomfortable wearing is obviously reduced.
In contrast, the hard plastic bite plate of the related art, both for the night molars and the clenchers, may cause some damage to the abutment, the teeth and periodontal tissues due to excessive force, and may continuously depress the dentition of the jaw. In addition, in adolescents in adolescence, the development of teeth (dentition) may be affected. However, the bite plate 111 made of the elastic plate body can well buffer and release larger force in the opening and closing process, and reduce traumatic stress on the tooth body and periodontal tissues, thereby protecting the tooth and periodontal tissues, being difficult to cause bite disorder and being worn for a long time.
The inventor of the present application found that, in order to avoid the snap or crack of the bite plate 111, even if the bite plate 111 is made of a soft material, when the bending requirement is too large, the bite plate 111 still has the risk of breaking or cracking due to the excessive force born by the bite plate 111, but if the elasticity of the bite plate 111 is continuously increased to improve the bending buffer performance, the unstable position between the bite plate 111 and the teeth may be brought, and the teeth may move under the action of the elastic deformation of the bite plate 111 itself, so as to affect the correction effect.
The bite plate 111 in this embodiment also has a bend relief structure 112, the bend relief structure 112 being used to provide bend relief to the bite plate 111.

The bending requirement of the occlusal plate 111 around the cavity for accommodating the teeth is more concentrated in the opening and closing process of a user, the bending buffer structure 112 is arranged corresponding to the cavity, the bending buffer structure 112 is arranged around the cavity for accommodating the teeth, and the bending buffer supplement can be provided for the region with concentrated acting force distribution in a targeted manner, so that the anti-breaking and anti-fatigue effects of the occlusal plate 111 are more excellent.
Bite plate 111 matches the arch of teeth, bite plate 111 being an arcuate plate covering at least one tooth along the circumference of the upper or lower jaw. The cavity comprises a tooth socket 120 for accommodating at least one tooth, one tooth socket 120 is used for accommodating one tooth, and a plurality of tooth sockets 120 are communicated with each other; the number of the tooth sockets 120 is specifically set according to the needs of the user, and is not specifically limited herein.
The geometry of the surfaces of the bite plate 111 facing outward toward the opposite jaw teeth corresponds to the geometry of the occlusal surfaces of the opposite jaw teeth.
As shown in fig. 1, when the occlusion groove 120 includes a plurality of tooth grooves 120, the tooth grooves 120 are sequentially arranged along an arc, at this time, the bending buffer structure 112 is also arranged along an arc, and is adapted to the arrangement mode of the tooth grooves 120, so as to effectively buffer the region with concentrated acting force, and greatly reduce the possibility of breaking or cracking of the bite training device.
The manner in which the bend relief structure 112 provides bend relief when the bite plate 110 is subjected to bending deformation may be at least one of the following: the bending buffer structure 112 can provide bending buffer to avoid the bending deformation of the bite plate 111 from breaking or cracking by adjusting the toughness of the bending buffer structure 112 to be better than that of the bite plate 111, adjusting the elastic modulus of the bending buffer structure 112 to be smaller than that of the bite plate 111 and adjusting the tear resistance of the bending buffer structure 112 to be smaller than that of the bite plate 111. Wherein, when the bending buffer structure 112 provides bending buffer, the elastic modulus of the bending buffer structure 112 is smaller than that of the occluding plate 111, and the material cost can be reduced, preferably, the elastic modulus of the occluding plate 111 is larger than 2000MPa.
When the bite trainer is used, the position stability between the bite plate 111 and teeth needs to be ensured, and the bite plate 111 and the teeth are prevented from moving relatively; the geometric form of the cavity can be matched with the teeth accommodated in the cavity of the occlusal plate 111, at the moment, the cavity is in fit contact with the inner surfaces of the teeth, the teeth are fully wrapped by the cavity, so that the position stability between the occlusal plate 110 and the teeth is ensured, the stable fixation between the occlusal plate 110 and the teeth is realized, and the movement of the occlusal plate 110 equivalent to the teeth is avoided; however, in addition, the overall bending deformation of the bite plate 111 can be further set to be not more than 6% of the self volume before deformation, so that the teeth are prevented from moving under the action of the elastic force of the bite plate 111 when the cavity fully wraps and fixes the teeth, and the position between the teeth and the bite plate 111 is further ensured to be relatively stable.

The inner surface A is fully attached to the outer surface of the corresponding position of the teeth accommodated in the cavity for wrapping contact, so that stable retention between the bite plate 111 and the teeth is realized; the curved expansion area formed between the inner surface B113 and the teeth received in the cavity increases the auxiliary retention and provides an expansion area for the curvature of the bite plate 111, reduces the risk of breakage or cracking of the bite plate 111, prolongs the service life of the bite plate 111, and reduces discomfort to the user.
Under the action of the inner surface A, the teeth accommodated in the cavity can be uniformly contacted with the occlusal plate 111, so that the overall stress of the teeth is uniform, uneven distribution of acting force applied to the teeth by the occlusal plate 111 is avoided, and the symptoms of nausea of a user are likely to be caused due to inconvenience in wearing.
The interval between the inner surface B113 and the tooth surface corresponding to the position of the inner surface B is d, d is more than or equal to 0.5mm and less than or equal to 2.0mm, the occupied volume of the bite plate 110 is reduced as much as possible on the premise of ensuring that a proper expansion area is provided for the bite plate 110, wearing comfort is improved, and foreign body sensation of a user during wearing is reduced.
