Description

Clasp for orthodontic instruments that are easy to attach and detach}

The present invention relates to a clasp for a dental orthodontic appliance, and more particularly, to a clasp for a dental orthodontic appliance including a structure that can be used in a removable orthodontic appliance, and in particular, a structure that facilitates the attachment and detachment of the orthodontic appliance.

Various types of orthodontic instruments are known to provide a wide range of therapeutic functions. The removable dental orthodontic appliance is configured to be detachable to the teeth, and is configured so that a patient can separate it in the oral cavity for a meal or an outside meeting, and can be mounted back in the mouth after a meal or meeting is over. In general, a removable orthodontic appliance is based on a resin lump (preferably acrylic resin lump) suitable for a patient's teeth, palate and lingual side. These instruments are manufactured in dental laboratories through impressions of the patient's teeth and soft tissues.

In addition, as a means for holding the detachable orthodontic appliance as described above on the teeth, a ball clasp made of a metal material as shown in FIG. 1 may be used. As shown in Fig. 1, the ball clasp 2 includes a line portion 21 having a diameter of approximately 0.7 mm, and a ball portion 22 formed at one end of the line portion 21 having a size larger than the diameter of the line portion 21. do. The ball clasp 2 is mainly used for orthodontic instruments that do not require a large holding force. The straight line portion 21 is bent and adheres in close contact with the outer shape of the tooth, and the bowl portion 22 contacts below the contact point of the adjacent tooth.

In addition, a roof clasp 3 as shown in FIG. 2 may be used as a means for holding the removable orthodontic appliance on the teeth. Like the ball clasp 2 shown in FIG. 1, the roof clasp 3 includes a wire portion 31 having a cross-sectional diameter of approximately 0.7 mm, and replaces the ball portion 22 of the ball scrap 2 with a wire. It includes a loop 32 formed by bending one end into a ring shape. In addition, a moyer clasp is also known, which is formed in a ball shape by coating a resin on the loop of the roof clasp.

However, conventionally, when a ball clasp, a loop clasp, or the like is attempted in the oral cavity, it is difficult for a patient to attach or detach it, thereby reducing discomfort in many cases.
