Connecting method and connecting body for lingual side of molar belt ring

Abstract

The invention discloses a connecting method and a connecting body for a lingual side of a molar belt ring. A substrate is fixed on the surface of the lingual side of the molar belt ring; a key way which is vertical to the axis of the molar belt ring is arranged on the substrate; a key and a fine metal wire for fixing are arranged on one end of a connecting rod; the key is inserted to the key way to form a connecting mechanism; the fine metal wire is clamped to the lower side of the key way to fix the whole connecting rod; force is applied to the molar belt ring by opening or bending the fine metal wire to dismount the molar belt ring. The substrate is fixed on the surface of the lingual side of the molar belt ring, and the key on the connecting rod can be vertically arranged in the key way on the substrate, so that an arch expanding device, a strengthening and supporting device and the molar belt ring are connected simply and efficiently, and can be simply dismounted for being regulated and applied force to re-wear the molar belt ring. Welding or tying needed for connecting the molar belt ring is avoided, so that processing time is saved; and moreover, the belt ring is not needed to be dismounted in every adjusting process, so that the pain of a patient is greatly relieved, and consultation hours is saved.

Description

technical field [0001] The invention discloses a method for connecting the lingual side of a molar belt ring, and also provides a connecting body for realizing the method, and belongs to the technical field of appliances for orthodontic tooth correction. Background technique [0002] Clinically, arch expansion devices are often used to correct posterior crossbite, and lingual arches, Nance arches, and transverse palatine rods are used to increase molar anchorage, and even to move molars distally. These treatments require elastic parts (such as four-eye springs) , lingual arch, Nance arch) are connected with the retention part (ring). The current connection method is the welding of the elastic part and the molar belt ring, or the lingual sheath connection on the lingual side of the belt ring. [0003] The use of soldering connection not only takes a long time in clinical operation and the steps are cumbersome, but also the belt ring must be removed every time it is adjusted...
