Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a self-fixing individualized mandibular retainer. Background Art

[0002] After patients with temporomandibular joint disc displacement undergo temporomandibular joint disc reduction surgery, in order to establish a good occlusal relationship, the patient's mandibular position needs to be adjusted to the ideal treatment position. Therefore, the patient needs to wear a retainer after surgery to stabilize the mandible in the appropriate position to improve the patient's occlusal relationship.

[0003] Existing mandibular retainers are customized according to the actual needs of patients. However, during use, the movement of the upper and lower jaws can cause the retainer to loosen or even fall off. After it falls off, it is impossible to seek medical attention immediately for adjustment, and it is often just put on directly, which results in the mandibular retainer being unable to produce a good treatment effect. Utility Model Content

[0004] The purpose of the utility model is to provide a self-fixing individualized mandibular retainer, which uses a fixing ring to be placed on the fixed teeth, and then the retaining ring is placed around the teeth in other positions to fix the mandible, and then the knob is adjusted to further tighten and fix the outer end and the inner end of the fixing ring, thereby increasing the fixing force. Even if it falls off due to external force, it can be re-fixed, thereby improving the practicality and durability of the retainer.

[0005] To achieve the above-mentioned purpose, a self-fixing individualized mandibular retainer is provided, comprising: a retaining ring, a fixing component is fixedly arranged on the top of the retaining ring, the fixing component comprises a fixing ring, an outer end, an inner end, an outer connecting sleeve, a threaded rod, a threaded sleeve, a knob and a stabilizing sleeve, the bottom of the fixing ring is fixedly connected to the retaining ring, the fixing ring is in a "C" shape, an outer end and an inner end are arranged on the fixing ring, the bottom of the outer end is fixedly connected to the outer connecting sleeve, the inner side wall of the outer connecting sleeve is rotatably connected to the threaded rod, the inner end surface of the threaded rod is fixedly connected to the knob, the circumferential surface of the inner end is fixedly connected to the threaded sleeve, the knob is located on the inner side of the threaded sleeve, and the stabilizing sleeve is fixedly connected to the circumferential surface of the outer end and the outer connecting sleeve.

[0006] According to the self-fixing individualized mandibular retainer, the retaining ring is a customized stainless steel mandibular retaining steel ring.

[0007] According to the self-fixing individualized mandibular retainer, the fixing ring, the outer connecting sleeve, the threaded rod, the threaded sleeve, the knob and the stabilizing sleeve are all made of stainless steel.

[0008] According to the self-fixing individualized mandibular retainer, the threaded rod is threadedly connected to the threaded sleeve.

[0009] According to the self-fixing individualized mandibular retainer, the stabilizing sleeve is located on the "C"-shaped notch of the fixing ring.

[0010] According to the self-fixing individualized mandibular retainer, the number of the fixing components is two and they are symmetrically distributed on the left and right sides of the retaining ring.

[0011] The above scheme has the beneficial effects of: by arranging a retaining ring, a fixing ring, an outer end, an inner end, an outer connecting rod, a threaded rod, a threaded sleeve, a knob and a stabilizing sleeve, the fixing ring is put on the fixed teeth, and the retaining ring is put around the teeth in other positions to fix the mandible, and then the knob is adjusted to further tighten and fix the outer end and the inner end of the fixing ring, thereby increasing the fixing force. Even if it falls off due to external force, it can be re-fixed, thereby improving the practicality and durability of the retainer.

[0012] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
