The present invention relates to a dental typodon, in particular a typodon for measuring the frictional force between an orthodontic bracket and an archwire.

It is common to use orthodontic brackets and wires to correct teeth in malocclusion. At the beginning of treatment, a bracket is attached to each of the patient's teeth and a single wire is inserted into the attached bracket, thereby ligating the bracket. It will be corrected. At this time, the friction force generated between the line and the bracket acts as one of the friction force of the orthodontic device that hinders the movement of the ideal tooth. However, it is practically impossible to completely eliminate such friction, so the focus should be on minimizing the friction between the line and the bracket, depending on the state of malocclusion of the patient.

For effective orthodontic treatment, the most suitable combination of wire and bracket should be selected according to the patient's malocclusion status, and for proper selection, it is important to experiment with friction force according to various brackets and wires and their ligation methods. In other words, various combinations of brackets and wires are attached to the resin teeth in the desired malocclusion state, thereby finding a combination in which the friction force between the brackets and the wires is minimized.

Various experimental devices or methods have been used to test the frictional force between the bracket and the ship. Most experiments in the prior art, by attaching a single bracket or a small number (two or three) of the bracket on the plane and inserting the wire into the bracket, and pulling the bracket or the wire to measure the friction force between the bracket and the wire Has been used. Using this method, it is possible to measure the frictional force according to the size, material, and ligation method of the ship, but the frictional force in the case where a large number of brackets are attached to the actual malocclusion tooth is measured. Because of this, there is a drawback that the friction force in the clinical cannot be predicted properly.

Recently, various studies have been conducted to maximize the clinical situation. Among them, Sandra P. Henao and Robert P. Kusy wrote the evaluation of the Frictional Resistance of Conventional and Self-ligating Bracket Designs Using Standardized Archwires and Dental Typodonts. Orthodontist, Vol 74, No. 2, 2004). Henao and Kusy have produced a model of a typodon model that simulates a patient's oral condition to measure the frictional force between the attached bracket and the line in the case of malocclusion. Several pairs of these typodont models were made and the various types of brackets and wires were attached to them. Henao and Kusy's test model is a friction force test that implements the patient's malocclusion state, which has the advantage of minimizing the error between the test result and the clinical result. However, since it is simply a model that mimics the patient's malocclusion state, there are disadvantages in that it takes time and cost to emulate numerous malocclusion states. Therefore, there is a limit to the accurate and easy implementation of any malocclusion state. In addition, even if you try to attach a variety of brackets and ships in the same malocclusion state, there is a need to repeatedly attach and detach the brackets and ships, there is a disadvantage that you must duplicate several identical models to reduce the effort of detachment. .
