Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment: see figure 1 , figure 2 shown.

[0013] A device for depressing the posterior teeth as a whole includes two posterior tooth segments fixed on the left and right sides by means of adhesives. Pad 1 and cast bracket 2 connecting the two, The pads are fixed to the maxillary posterior segment or the tooth to be depressed on each side with adhesive, A traction hook 3 is embedded in the buccal side of the pad, a rubber chain 4 is hung on the traction hook, and the other end of the rubber chain is suspended on the implant nail 5 implanted in the zygomatic alveolar ridge; a plastic base is set in the middle of the cast bracket 6; The distance between the casting bracket and the palate mucosa is 3-5mm.

[0014] Pads, rubber chains, and implant nails together form a functional module. The force of the rubber chain is used to depress the poster...

Abstract

The invention discloses a device for integrally lowering posterior tooth segments. The device comprises two diastema pads and a casting stent, wherein the two diastema pads are fixed on left and right posterior tooth segments on two sides by adhesives; the casting stent is used for connecting the two diastema pads; a towing hook is arranged on a cheek side of each diastema pad; a rubber chain is suspended on each towing hook; the other end of each rubber chain is suspended on a mini-screw implanted into an infrazygomatic crest. The device has the advantages that the posterior tooth segments can be integrally lowered, few screws are implanted, both left and right posterior tooth segments are integrally pressed, the phenomenon that the left and right posterior tooth segments are uneven can be avoided, and the action force totally comprises three parts which are composed of tension force generated by the rubber chains, occlusal force generated by teeth on upper and lower jaws and pressure generated by the tongue.

Description

technical field [0001] The invention relates to a device for depressing the excessively elongated posterior teeth which affect the occlusal of the anterior teeth, in particular to a device for depressing the posterior segment as a whole. Background technique [0002] front teeth open It is a term in stomatology; in layman's terms, when the upper and lower jaws are closed, the upper and lower front teeth cannot be occluded, and there is a gap; the front teeth are open There are many hazards, causing the front teeth to be unable to cut food, affecting the patient's breathing, swallowing, and pronunciation. [0003] front teeth open There are many reasons for this, and the main manifestations are: individual or multiple back teeth in the oral cavity are elongated too long, and when the back teeth occlude, they form a fulcrum effect, so the front teeth cannot be closed; The buccal and palatal side of the elongated tooth is implanted with a small titanium plate or implant n...
