molar depressor

Abstract

The invention provides a molar intrusion apparatus, which comprises a metal casting frame attached to a palate, wherein the metal casting frame is fixed on the oral cavity palate by using implanting screws, the tail portion of the metal casting frame is provided with two semilunar rings, the two semilunar rings are respectively snapped on distalizations of the final molars of the palate, each semilunar ring is provided with two hooks, the hooks are respectively positioned on the buccolingual side of the orthodontically treated molar, the hook and elastic ring traction form a sleeved connection, the elastic ring traction forms a sleeved connection on a tongue side buckle or a buccal tube on the molar, and the hook is positioned on a gum side of the tongue side buckle or the buccal tube. According to the molar intrusion apparatus, during an orthodontic process of teeth, with the molar intrusion apparatus, strong anchorage can be provided, effective molar intrusion can be ensured, a force applying direction and tooth long axis can be consistent, it is ensured that the molar does not generate other adverse tilting movements, patient discomfort during use can be reduced, the implanting screw is absolute anchorage, and an intrusion effect is significant.

Description

Technical field [0001] The invention relates to a dental appliance, in particular to a molar depressor. Background technique [0002] In the prior art, conventional molar depression is either with an extra-oral device, and the patient cannot cooperate well, or it is directly pressed with implant nails, but some parts of the oral cavity are not suitable for implant nails; therefore, during the tooth correction process How to provide strong anchorage, ensure effective reduction of molars, apply to the reduction of molars in various positions, and reduce the discomfort of patients during use, is a problem that should be considered and resolved. Summary of the invention [0003] The purpose of the present invention is to provide a molar depressor, which can provide strong anchorage during the orthodontic process, ensure that the molars are effectively depressed, and the force direction can be consistent with the long axis of the teeth to ensure that the molars are not It produces oth...
