Embodiment 1

[0099] This embodiment provides a dental instrument, see figure 1 - Fig. 5 is a schematic structural view of the dental instrument of this embodiment, the dental instrument includes a first shell-like body 100 and a second shell-like body 200, the first shell-like body 100 includes several teeth for accommodating the maxillary teeth The first cavity, the second shell-shaped body 200 includes several second cavities for accommodating the teeth of the lower jaw, and the occlusal surface of the posterior teeth of the first shell-shaped body 100 is also provided with a protrusion protruding toward the opposite jaw. The raised part 300; the occlusal surface of the posterior teeth region of the shell-shaped body of the raised part 300 facing the opposing dentition is also provided with an occlusal surface of the posterior teeth region of the opposite jaw in contact with the raised part 300; the first shell The first shell-shaped body 100 and the second shell-shaped body 200 are fixe...

Embodiment 2

[0111] This embodiment provides a dental instrument. The structure of the dental instrument in this embodiment is similar to that of the dental instrument described in Embodiment 1. The difference lies in that the first shell-like body 100 and the second The two shell-shaped bodies 200 are fixedly connected by welding.

[0112] see Figure 6 , is a structural schematic diagram of the dental instrument of this embodiment, wherein the first welding area 140 is set on the side facing the opposing jaw of the raised portion 300, and the second welding area 240 is set on the occlusal surface of the posterior tooth region of the second shell-shaped body, the second When the relative positional relationship between the first shell body 100 and the second shell body 200 is fixed, the first welding area 140 is welded to the second welding area 240 . For example, by cold welding or laser welding, the first welding region 140 and the second welding region 240 are partially melted to form...

Embodiment 3

[0115] This embodiment provides a dental instrument. The structure of the dental instrument in this embodiment is similar to the structure of the dental instrument described in Example 1 or Example 2. The difference is that the first shell-shaped The main body 100 and the second shell-shaped main body 200 are fixedly connected through the first connection structure.

[0116] see Figure 7 , wherein the connecting structure includes a first connecting device 41 passing through the side of the raised portion 300 facing the opposite jaw and the occlusal surface of the second shell body 200 in the posterior region, and fastening the raised portion 300 and the second connecting device 42 of the second shell-shaped body 200, the first connecting device 41 and the second connecting device 42 cooperate with each other to realize the first shell-shaped body 100 and the second shell-shaped body 100 The fixed connection of the body 200.

[0117] Further, the first connection device 41 ...

Abstract

The invention discloses a dental instrument, a correction system and a design method and a manufacturing method of the dental instrument, the dental instrument comprises a first shell-shaped body, a second shell-shaped body and a convex part, the first shell-shaped body and the second shell-shaped body are fixedly connected, the first shell-shaped body and the second shell-shaped body are arranged in a manner of fixing the upper jaw and the lower jaw to a target correction position and opening the occlusion relationship between the upper jaw and the lower jaw. The protruding part has the effect of opening the occlusion relation between the upper jaw and the lower jaw, jaw position reconstruction is facilitated, the first shell-shaped body and the second shell-shaped body enable the upper jaw teeth and the lower jaw teeth to be gradually changed from the initial positions to the target correction positions, and meanwhile the relative positions of the upper jaw and the lower jaw are adjusted; the dental instrument can achieve the effects of jaw position reconstruction and malocclusion correction at the same time, and in addition, the dental instrument is convenient to take off, wear and store and has the advantages of being comfortable to wear and low in foreign body sensation.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a dental device connected with a shell-shaped body of the upper and lower jaws, an orthodontic system, and a design method and a manufacturing method of the dental device. Background technique [0002] Malocclusion refers to the deformity of teeth, jaw, and craniofacial caused by congenital genetic factors or acquired environmental factors during the growth and development of children. Such as misalignment of teeth, protruding upper teeth, protruding jaw, crooked mouth, etc. With the continuous deepening of clinical research, the concept of modern malocclusion is far from just referring to misalignment and misalignment of teeth, but Refers to a variety of deformities caused by the imbalance between teeth and craniofacial relationship. The hazards of malocclusion are mainly reflected in four aspects: function, appearance, health and psychology. It affects the...
