Problems solved by technology

[0003] At present, the orthodontic appliances for early orthodontic children in the dentition period are mainly soft silicone orthodontic appliances (such as MRC, Rohm, etc.), which are mainly used to correct bad oral and maxillary muscle function habits, and have limited ability to correct malocclusion. , mainly manifested as sagittal and lateral induction through anterior labial alignment and lateral expansion of the arch, lack of vertical induction management; more importantly, this type of appliance does not treat the key causes of dental and maxillofacial deformities , may lead to exacerbation of the condition, significant side effects and complications

Embodiment 1

[0035] Figure 1 to Figure 4 It shows a schematic structural diagram of a child maxillofacial three-dimensional growth guiding appliance according to an embodiment of the present invention, which includes a clinching layer 100, and the clinching layer 100 has a size adapted to the shape of the patient's dental arch, according to the male / female size There are some distinctions, and they are also divided into pointed circle, oval circle and square circle, etc., thus defining the upper occlusal surface 130 suitable for the occlusal of the maxillary teeth.

[0036] Such as image 3 As shown, in this embodiment, the cushion layer 100 is formed by bonding two layers in the thickness direction, namely the upper cushion layer 110 and the lower cushion layer 120, and the upper occlusal surface 130 is specifically formed by the upper cushion layer 110. limited by, image 3 The upper mat layer 110 and the lower mat layer 120 of the mat layer 100 are divided by dotted lines.

Embodiment 2

[0048] Figure 5 to Figure 8 It shows a schematic structural view of a child maxillofacial three-dimensional growth guiding appliance according to another embodiment of the present invention, which includes a clinching layer 400, and the clinching layer 400 has a size adapted to the shape of the patient's dental arch. According to male / female There are different sizes, and they are divided into pointed circle, oval circle and square circle, etc., thus defining the upper occlusal surface 430 suitable for occlusal of the upper row of teeth.

[0049] Such as Figure 7 As shown, in this embodiment, the cushion layer 400 is formed by bonding two layers in the thickness direction, which are the upper cushion layer 410 and the lower cushion layer 420, and the upper occlusal surface 430 is specifically formed by the upper cushion layer 410. limited by, Figure 7 The dotted line divides the upper mat layer 410 and the lower mat layer 420 of the mat layer 400 .

Abstract

The invention provides a children maxillofacial region three-dimensional growth guiding corrector which comprises an occlusal cushion layer, the occlusal cushion layer comprises a first hardness area and a second hardness area, and the first hardness area and the second hardness area define a first upper occlusal surface and a second upper occlusal surface respectively. The material hardness of the first hardness area is greater than that of the second hardness area.

Description

technical field [0001] The invention relates to the field of orthodontic appliances, in particular to a three-dimensional growth-guiding appliance for children's maxillofacial region. Background technique [0002] The change of maxillofacial shape depends on the growth difference in the three-dimensional directions (sagittal, transverse and vertical) of the upper and lower jaws. In the vertical direction, when the posterior tooth area of ​​the jaw is overdeveloped vertically, the occlusal plane tends to be flat, which will cause the mandible to rotate forward and upward, forming a "underground" or concave deformity; on the contrary, if the posterior tooth area grows vertically Insufficient, the anterior region grows faster, the occlusal plane tends to be steeper, and the position of the mandible is passively rotated backward, which eventually leads to convex deformity, mandibular retrusion and airway narrowing. Therefore, starting from the theory of maxillofacial growth and...
