Description

Shell-shaped dental instrument, shell-shaped dental instrument set and dental correcting system

Technical Field

The utility model belongs to the field of medical equipment, a shellliform dental instrument, shellliform dental instrument suit and dentistry are rescued and are made system is related to.

Background

The term occlusions (occlusions) is a term specific to oral medicine. occlusion in the webster dictionary means that the opposing surfaces of the upper and lower jaw teeth are brought together. In the past, "occlusions" were used to indicate the contact of the upper and lower teeth when the lower jaw is stationary, while occlusions (occlusions) were used to indicate the contact of the upper and lower teeth when the lower jaw is moving. In the modern concept of oral profession, the above two meanings of movement and inertia are included, namely, in some cases, the meaning is common to occlusion.

Malocclusion refers to congenital genetic factors or acquired environmental factors such as diseases, bad habits of the oral cavity, dysdonia of tooth replacement, etc., and may also be caused by trauma and periodontal diseases after growth, such as misalignment of teeth, abnormal occlusion of upper and lower dental arches, abnormal size and position of jaw, facial deformity, etc. The factors and mechanisms of malocclusion are intricate, and the process of occurrence may be effected by a single factor and a single mechanism, or may be the result of multiple factors or multiple mechanisms acting together. The pathogenesis of the malocclusion deformity can be divided into two categories, namely congenital factors and acquired factors, from the time of the formation of the malocclusion deformity, but aiming at the generation mechanism of the individual malocclusion deformity, the pathogenesis of the malocclusion deformity can be divided into internal genetic factors and external environmental factors.

The invisible tooth appliance is comfortable to wear, can be taken off and worn, is attractive, is selected by more and more people, needs to be closely attached to teeth when being worn, and is matched with the attachments stuck to the teeth to be corrected. At present, the purpose of opening occlusion is achieved by mostly arranging jaw cushions on teeth, but the fixing and correction are realized by sticking resin plastics and the like on the teeth and fixing the resin plastics and the adjacent teeth by using metal wires to achieve the purpose of opening and closing, but the jaw cushions cannot be only partially applied to the invisible correction in the above mode, and the hidden teeth correction device needs to wrap the whole dentition to achieve the correction process, so that a patient has strong constraint feeling and poor comfort when wearing the hidden teeth correction device for the first time; in addition, for invisible correction, the method for opening occlusion is to stick resin and other intraoral materials on the surface of the invisible corrector, but the method has low combination degree, is easy to fall off, and cannot achieve the corresponding correction purpose.

Therefore, the research on the dental instrument which has the functions of safety, comfort and convenience and can adjust the jaw position relation is of great significance.

Referring to fig. 5, the present embodiment provides a set of shell-shaped dental appliances, including a first shell-shaped dental appliance for maxillary dentition and a second shell-shaped dental appliance for mandibular dentition; the first shell-shaped dental instrument is the shell-shaped dental instrument described in embodiment 1, the second shell-shaped dental instrument includes a fifth shell-shaped body 300, the fifth shell-shaped body 300 is provided with a plurality of second cavities for accommodating second dentition, and a position of the fifth shell-shaped body corresponding to the protruding portion 2 of the first shell-shaped dental instrument is provided with a limiting portion 301 which is matched with the friction portion of the first shell-shaped dental instrument and promotes occlusion induction.

The limiting part 301 is one or a combination of two or more of a structure which is matched with the occlusal surface of the corresponding posterior tooth area of the first shell-shaped dental instrument in a concave-convex manner, a structure which is matched with the occlusal surface of the first shell-shaped dental instrument in an occluded manner, a structure with a frosted surface, a structure with a hollowed-out surface, a structure which is provided with an opening on the occlusal surface of the corresponding posterior tooth area of the jaw teeth or a structure which does not cover the fifth shell-shaped body structure in the posterior tooth area. Spacing portion 301 cooperates with bellying 2 that sets up on first shell-shaped body 100 and the second shell-shaped body 200 among the first shell-shaped dental instrument, increases relative friction for the occlusal relation of jaw is more firm, accomplishes the occlusion and rebuilds.

The second shell-shaped dental appliance is a shell-shaped body wrapping the mandibular dentition, so that the dental appliance worn by the mandible is of an integrated structure, more steps are avoided when a split structure is used for wearing, the dental appliance is convenient for a patient to take off and wear, and a similar or better correction effect is achieved.

Example 6

The dental correcting system of the embodiment can be applied to one of correction stages in cross-jaw deformity correction of Anshi II or Anshi III, namely, can finish the occlusion reconstruction process of upper and lower jaws, and at least one shell-shaped dental instrument set in embodiment 5 is used in the process to carry out occlusion reconstruction of the upper and lower jaws, namely, the shell-shaped dental instrument set in embodiment 5 is used in at least one correction stage to carry out occlusion reconstruction of the upper and lower jaws. When the orthodontic process comprises 2 and more than 2 bite reconstruction orthodontic stages, the bulge height of the bulge part in the shell-shaped dental appliance used in the second orthodontic stage is smaller than that of the bulge part in the shell-shaped dental appliance used in the first orthodontic stage, wherein the wearing time of each shell-shaped dental appliance is 7-14 days. If more stages of correction are involved, the height of the projections gradually decreases as the correction process progresses. During the treatment process, the shell-shaped dental appliance has the effect of opening occlusion, so that the lower jaw is induced to retract or extend forwards, and occlusion reconstruction is completed. The malocclusion of patient is corrected gradually, and along with correcting going on of process, the protruding height of the bellying of shell form body reduces along with correcting going on of process gradually, and the completion back is rescued to the stage, and the interlock need not opened to the upper and lower jaw, then can get rid of the bellying, accomplishes the stage and rescues. The orthodontic time of the dental orthodontic system of the embodiment is about 0 to 6 months.

It should be noted that the above embodiments can be freely combined as necessary. The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
