Technical Field

The invention relates to the field of dental instruments, in particular to an asymmetric occlusal pad for treating deviated jaw deformity.

Background

Hemimandibular deformity is the most common manifestation of facial asymmetry and may be associated with congenital, developmental or acquired condyloid process abnormalities of the mandible. The deviated jaw deformity has adverse effects on the appearance, chewing, pronunciation and sleeping respiratory function of a patient, and the severity of the deviated jaw deformity is generally clinically measured by the deviation of the chin.

The existing methods for treating the deviation of the chin mainly comprise simple orthodontic treatment, orthodontic and orthognathic combined treatment and the like. While the pure orthodontic treatment is only effective on some mild bone-derived deformities, most of mandibular deviation deformities must be solved by orthodontic orthognathic surgery, but the surgical treatment has large trauma, high risk, long treatment period and high cost, and is difficult to be accepted by most patients.

Disclosure of Invention

Clinical research shows that patients with deviated chin are often accompanied by mandibular ascending and descending differences caused by deviated occlusal plane or asymmetric left and right condyles, based on the difference, the invention improves common clinical occlusal pads, provides an asymmetric occlusal pad for treating deviated jaw deformity, reduces the pressure of temporomandibular joints on the deviated side by using the asymmetric elongation of posterior teeth, promotes the growth of condyloid processes, and achieves the effect of correcting the deviation of the chin.

In order to achieve the purpose, the invention adopts the technical scheme that: an asymmetric occlusal pad for treating deviated jaw deformity comprises an occlusal pad body and a stainless steel wire, wherein the occlusal pad body comprises 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, and the shape of the arc-shaped connector is matched with the shape of an alveolar bone at the upper palate or the lower jaw tongue side of an oral cavity; the stainless steel wire is embedded in the occlusal pad, one end of the stainless steel wire penetrates out of the left occlusal pad, and the other end of the stainless steel wire penetrates out of the right occlusal pad and is respectively bent to form an adjacent hook hooked on the outer surface of the tooth.

Further, the diameter of the stainless steel wire is 0.8mm or 0.9 mm.

Furthermore, the left side occlusal cushion block, the right side occlusal cushion block and the arc-shaped connector are integrally formed and made of thermosetting resin.

Furthermore, the thickness of the left occlusal cushion block, the right occlusal cushion block and the arc-shaped connector is about 3-5 mm.

Furthermore, the shape of the arc-shaped connecting body is matched with the shape of the alveolar bone at the palate or the mandibular-lingual side of the oral cavity, the bottom surfaces of the left occlusal cushion block and the right occlusal cushion block are matched with the occlusal surface of the teeth, the buccal and lingual surfaces are smooth, and the width of the buccal and lingual surfaces is matched with the width of the buccal and lingual sides of the teeth of a patient.

Furthermore, the left side occlusal cushion block and the right side occlusal cushion block are arranged between partial maxillary posterior teeth and partial mandibular posterior teeth, one side of the left side occlusal cushion block and the right side occlusal cushion block covers all posterior tooth sections, the other side of the left side occlusal cushion block only covers the premolar section, and a space for tooth extension exists between the other maxillary posterior teeth and the mandibular posterior teeth, so that teeth are asymmetrically extended.

The invention has the following beneficial effects:

1) the asymmetrical occlusal pad only covers the front molar section on the inclined side, and the other side covers all the posterior teeth and the front molar section, so that the posterior teeth on the inclined side of the chin can be extended, thereby achieving the purposes of relieving the pressure of the temporomandibular joint area on the inclined side and promoting the growth of the condyloid process;

2) the structure is simple, the manufacture is convenient, the clinical application is easy, and the application of a clinician is convenient;

3) the patient wears convenient and comfortable, and the expense is cheap, and risk-free does benefit to clinical popularization and application.

Detailed Description

In order that the objects and advantages of the invention will be more clearly understood, the invention is further described in detail below with reference to examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1-2, the invention proposes to use the asymmetric design of the occlusal pad for the first time to create an extension gap for the posterior teeth on one side, and provides an asymmetric occlusal pad for treating deviated jaw deformity, which comprises an occlusal pad body and a stainless steel wire 4, wherein the occlusal pad body comprises 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 is matched with the shape of the alveolar bone on the palate or lingual side of the lower jaw; the stainless steel wire 4 is embedded in the occlusal pad body, one end of the stainless steel wire 4 penetrates out of the outer side of the left occlusal pad block 1, and the other end of the stainless steel wire 4 penetrates out of the outer side of the right occlusal pad block 2 and is respectively bent to form an adjacent hook 5 hooked on the outer surface of a tooth. The diameter of the stainless steel wire is 0.8mm or 0.9 mm. The left side occlusal cushion block 1, the right side occlusal cushion block 2 and the arc-shaped connector 3 are integrally formed and made of thermosetting resin. The thickness of the left occlusal cushion block 1, the right occlusal cushion block 2 and the arc-shaped connector 3 is about 3-5 mm.

In this embodiment, the shape of the arc-shaped connector 3 is matched with the shape of the alveolar bone on the palate or the lower jaw tongue side of the oral cavity, the bottom surfaces of the left occlusal pad 1 and the right occlusal pad 2 are matched with the occlusal surface of the teeth, the buccal tongue surface is smooth, and the width is matched with the width of the buccal tongue side of the teeth of a patient.

In this embodiment, the left occlusal pad 1 and the right occlusal pad 2 are placed between partial maxillary posterior teeth and partial mandibular posterior teeth, one of which covers the entire posterior tooth segment, and the other of which covers only the premolar segment, so that a space for teeth to extend exists between the remaining maxillary posterior teeth and the mandibular posterior teeth, and teeth are asymmetrically extended. Such as: the left side occlusal cushion block only covers the front molar section, and the right side covers the front molar and the molar section, so that the left side molar actively extends to further correct the left deviation of the chin of a patient.

The specific implementation corrects the deviation of the chin of a patient by enabling the two posterior teeth to generate asymmetrical active elongation through the asymmetrical occlusal pad, namely the elongation of the oblique posterior teeth.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be construed as the protection scope of the present invention.
