Problems solved by technology

[0003] However, most of the above treatment methods are fixed treatment methods, which not only cause great damage to the user's oral cavity, but also make the user's experience and comfort poor.
In addition, during the operation of the above correction process, it is necessary for the user to insert the wrench into the small hole of the intraoral device to perform the bow expansion operation, which greatly increases the inconvenience of the user's bow expansion, and it is also easy for the small wrench to fall into the mouth during operation. Risk of airway obstruction in the mouth
Traditional four-eye spring expanders often cause discomfort to users because their metal parts are easy to compress mucous membranes
Invisible orthodontic appliances are chosen by more and more people because they are comfortable to wear, detachable, and beautiful. Invisible orthodontic appliances themselves also have a partial arch expansion effect, but due to the small arch expansion force, the arch expansion effect is poor. The molars should be expanded forward and backward in order to prolong the expansion cycle

Embodiment 1

[0057] In the step S1 of Embodiment 1 of the present invention, the user is scanned in the mouth, the scan is covered by the user's upper jaw and upper bow to acquire the initial dental digital model including the upper class digital model. .

[0058] In some embodiments of the present invention, the user is used to obtain the user in the mouth of the user to acquire the solid printing model, and the solid stam model comprises upper-chromaticizing mold and maxillary printing; transforming the solid stam model to After the solid positive mold model, the solid positive mold model is scanned to obtain the initial dental digital model including the upper 部 digital model.

[0059] In the step S2 of Embodiment 1 of the present invention, the feature information includes dimension information and preset position information of the upper paternity digital model. The preset position information of the upper tripoparamine is provided in both ends of the latcheshot to the initial teeth, and ...

Embodiment 2

[0083] The design method provided in Example 2 of the present invention is different from the design method provided in Example 1 in that the upper tab is an enhanced portion that enhances the expansion or contraction of the upper paternity. The reinforcing portion is provided in at least one reinforcing ridge that is consistent with the bending arc of the upper palate or different. The section of the reinforcing ridge is a cross section in the distant direction of the stride as an intermittent cross section or a continuous cross section, and when a continuous cross section, the reinforcing ridge is capable of producing sufficient force, thereby achieving the effect of the expansion or contravement.

[0085] Refer Figure 2A and Figure 4 The main difference between the second dental correction ...

Embodiment 3

[0102] In Embodiment 3 of the present invention, the cross section of the reinforcing ridge cross-sectional surface is designed to be provided below the cross section of the upper cross section. More specifically, the reinforcing ridge is provided along the upper parselax cross section and is only a reinforcing ridge provided by the lower side.

[0103] Figure 5b The three curved reinforcing ridges obtained by the design method of the present invention and the preparation method of the present invention and the structures of the first parselant composed of the first parselade are cross sections along the far direction.

[0104] Refer Figure 5b , The design conditions of the fourth curved reinforced ridge 41, the fifth curved reinforcement ridge 42, and the sixth curved reinforcement ridge 43 are respectively reinforced with the first curved shaped ridge 31 in Example 2, and the The set of the second curved reinforcing ridge 32 and the third curved reinforcing ridge 33 are substan...

Abstract

The invention provides a design method of a dental orthodontic appliance, comprising obtaining an initial digital model of the teeth and jaws; designing a digital model of the upper palate arch with characteristic information; generating a digital model of the teeth and jaws with the digital model of the upper palate arch, and designing the dental orthodontic appliance . The feature information includes size information and preset position information of the palatal arch digital model, and the preset position information of the palate arch is that the two ends of the palate arch are set in the posterior region of the initial dental jaw digital model At the gingival margin on the lingual side or near the gingival margin on the lingual side, so that when the dental appliance interacts with the teeth, the palatal arch can induce the lateral expansion of the maxillary palatine suture bone deposition through deformation, and the teeth in the posterior teeth area With the action of the orthodontic appliance, the buccolingual moves laterally. The invention also provides a preparation method of the dental correction appliance.

Description

Technical field [0001] Technical Field The present invention relates to medical instruments, in particular, it relates to a design method and method of preparing a dental treatment instrument. Background technique [0002] In the admissions user orthodontist in, crowding is a common clinical manifestations, although commonly used coercive treatment designed to extractions, interproximal enamel, pushing the gap to provide a molar distal lip or tilt dental and other methods. But there are also a part of the user, crowded mainly for insufficient arch width, arch width in the open, crowded to be improved. Arch expansion is a common method of treatment of the arch width is not adjusted, a common method of fixing palatal arch expansion arch-expanding, four Helix expansion, Knight bow arch expansion, auxiliary arch expansion screw implant, surgical auxiliary arch expansion, etc. . Invisible appliance also has a certain arch expansion capability, previous studies have shown that the comb...
