Device for quickly forming orthodontic ligature wire

Abstract

The invention provides a device for quickly forming an orthodontic ligature wire. Two ends of a stainless steel side frame are respectively connected with stainless steel round wires; two stainless steel square wires the cross sections of which are in round rectangles are respectively positioned at the inner sides of the stainless steel round wires and are connected with the stainless steel side frame; the two stainless steel round wires and the two stainless steel square wires are mutually parallel; and a handle which is in the same direction with the stainless steel round wires and is connected with the stainless steel side frame in the vertical direction is arranged at the middle part of the other side of the stainless steel side frame. The tip of the ligature wire formed by the invention is in a semicircle (about 2mm), thus the ligature wire can be conveniently hung on a hook with a ring in the back ligaturing process of canine teeth. When a bracket is ligatured, an approximately square part in the middle of the formed ligature wire is arranged parallel to an arch wire and is placed below a bracket wing and then pulled to the other direction along the traveling direction of the arch wire, so that the ligature wire can be placed below the bracket wing for ligaturing.

Description

Technical field: [0001] The invention relates to a ligature wire for orthodontics, in particular to a rapid prototyping device for a ligature wire used clinically in orthodontics. Background technique: [0002] With the improvement of people's living standards and the enhancement of aesthetic awareness, there are more and more orthodontic patients in oral clinic. Orthodontic patients are mainly treated with fixed appliances, that is, the brackets are bonded to the tooth surface, and then the arch wire is ligated and fixed on the brackets to exert force on the teeth. The clinical ligation method mainly uses an elastic ligation ring and a stainless steel ligation wire with a diameter of 0.020mm. However, the elastic ligature ring is expensive, which greatly increases the cost of correction, so it is rarely used, and stainless steel ligature wire is routinely used clinically. However, the ligature wires generally available in the market are all in rolls, and they need to be c...

Problems solved by technology

However, the elastic ligature ring is expensive, which greatly increases the cost of correction, so it is rarely used, and stainless steel ligature wire is routinely used clinically.

However, the ligature silk generally bought in the market is in rolls, and it needs to be cut into small pieces with scissors before use, which is extremely inconvenient and greatly increases the operating time of clinicians.
