Description

Technical Field

[0001] The invention relates to the field of dental instruments, and in particular to an asymmetric occlusal pad for treating jaw deformity. Background Art

[0002] Jaw deviation is the most common manifestation of facial asymmetry, which may be related to congenital, developmental or acquired condylar abnormalities of the mandible. Jaw deviation can have adverse effects on the patient's appearance, chewing, pronunciation and sleep breathing function. Clinically, the severity of mandibular deviation is generally measured by the size of the chin deviation.

[0003] At present, the main methods for treating chin deviation include simple orthodontic treatment, orthodontic and orthognathic combined treatment, etc. Simple orthodontic treatment is only effective for some mild bone deformities. For most mandibular deviation deformities, orthodontic and orthognathic surgery must be used to solve them. However, surgical treatment is traumatic, risky, has a long treatment period, and is expensive, making it difficult for most patients to accept. Summary of the invention

[0004] Clinical studies have shown that patients with chin deviation often have differences in the mandibular ascending ramus caused by occlusal plane deviation or asymmetry of the left and right condyles. Based on this, the present invention improves the commonly used clinical occlusal pads and provides an asymmetric occlusal pad for treating jaw deviation. The asymmetric elongation of the posterior teeth is used to reduce the pressure on the temporomandibular joint on the deviation side and promote the growth of the condyle, thereby achieving the effect of correcting the chin deviation.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: an asymmetric occlusal pad for treating jaw deviation, comprising an occlusal pad body and a stainless steel wire, the occlusal pad body comprising a left occlusal pad block, a right occlusal pad block, and an arc-shaped connector for connecting the left occlusal pad block and the right occlusal pad block, the shape of the arc-shaped connector matches the morphology of the alveolar bone on the lingual side of the upper palate or mandible in the oral cavity; the stainless steel wire is embedded in the occlusal pad body, and one end of the stainless steel wire passes through the outside of the left occlusal pad block, and the other end passes through the outside of the right occlusal pad block, and they are respectively bent to form interproximal hooks that are hooked on the outer surface of the teeth.

[0006] Furthermore, the diameter of the stainless steel wire is 0.8 mm or 0.9 mm.

[0007] Furthermore, the left occlusal pad, the right occlusal pad and the arc-shaped connector are integrally formed using thermosetting resin.

[0008] Furthermore, the thickness of the left occlusal pad, the right occlusal pad, and the arc-shaped connector is about 3-5 mm.

[0009] Furthermore, the shape of the arc connector matches the morphology of the alveolar bone on the lingual side of the upper palate or mandible in the oral cavity, the bottom surfaces of the left occlusal pad and the right occlusal pad match the occlusal surfaces of the teeth, the buccal and lingual surfaces are smooth, and the width is adapted to the buccal and lingual width of the patient's teeth.

[0010] Furthermore, the left occlusal pad and the right occlusal pad are placed between part of the maxillary posterior teeth and mandibular posterior teeth, with one side covering the entire posterior tooth segment and the other side only covering the premolar segment, so that there is space for tooth extension between the remaining maxillary posterior teeth and mandibular posterior teeth, resulting in asymmetrical extension of the teeth on one side.

[0011] The present invention has the following beneficial effects:

[0012] 1) The asymmetric occlusal pad of the present invention only covers the premolar segment on the deviated side, and covers all the posterior teeth and premolar segments on the other side, so that the posterior teeth on the deviated side of the chin can be extended, thereby achieving the purpose of reducing the pressure on the temporomandibular joint area on the deviated side and promoting the growth of the condyle;

[0013] 2) It has a simple structure, is easy to manufacture, is easily available in clinic, and is convenient for clinicians to use;

[0014] 3) It is convenient and comfortable for patients to wear, low-cost, risk-free, and conducive to clinical promotion and application. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] like Figure 1-Figure 2As shown, the present invention proposes for the first time to use the asymmetric design of the occlusal pad to create an elongation gap for the unilateral posterior teeth, and provides an asymmetric occlusal pad for treating jaw deviation, including an occlusal pad body and a stainless steel wire 4, wherein the occlusal pad body includes a left occlusal pad block 1, a right occlusal pad block 2, and an arc-shaped connector 3 for connecting the left occlusal pad block 1 and the right occlusal pad block 2, and the shape of the arc-shaped connector 3 matches the morphology of the alveolar bone on the upper palate or mandibular lingual side of the oral cavity; the stainless steel wire 4 is embedded in the occlusal pad body, and one end of the stainless steel wire 4 passes through the outside of the left occlusal pad block 1, and the other end passes through the outside of the right occlusal pad block 2, and is bent to form an interproximal hook 5 hooked on the outer surface of the tooth. The diameter of the stainless steel wire is 0.8mm or 0.9mm. The left occlusal pad block 1, the right occlusal pad block 2, and the arc-shaped connector 3 are integrally formed and adopt thermosetting resin. The thickness of the left occlusal pad 1, the right occlusal pad 2 and the arc-shaped connector 3 is about 3-5 mm.

[0021] In this embodiment, the shape of the arc connector 3 matches the morphology of the alveolar bone on the lingual side of the upper palate or mandible in the oral cavity, the bottom surfaces of the left occlusal pad 1 and the right occlusal pad 2 are consistent with the occlusal surfaces of the teeth, the buccal and lingual surfaces are smooth, and the width is adapted to the buccal and lingual width of the patient's teeth.

[0022] In this embodiment, the left occlusal pad 1 and the right occlusal pad 2 are placed between part of the maxillary posterior teeth and the mandibular posterior teeth, with one side covering the entire posterior teeth segment and the other side only covering the premolar segment, so that there is space for the remaining maxillary posterior teeth and the mandibular posterior teeth to extend, and the teeth on one side extend asymmetrically. For example, the left occlusal pad only covers the premolar segment, and the right side covers the premolar and molar segments, so that the left molar actively extends and corrects the patient's left chin deviation.

[0023] In this specific implementation, an asymmetric occlusal pad is used to cause the posterior teeth on both sides to produce asymmetric active extension, that is, the posterior teeth on the deviated side are extended, so as to correct the patient's chin deviation.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
