Description

[0001] Jawbone Incising Device [

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a jaw incision apparatus that forms a wound on a jaw such as an alveolar bone, and more particularly, to a jaw incision apparatus that punctures the jaw for orthodontic treatment to form a incision on the jaw.

In modern society, esthetics has become increasingly important as a function of dental orthodontic treatment. In particular, the desire to improve the esthetics of the adults and the interest of the dental health are increasing due to the increase of the average life span and the decrease of the number of children, and the general dentist 's awareness about the necessity of the correction is changed.

For growing patients, such as children or adolescents, the orthodontic treatment may compensate for a number of problems in the growth and development of the patient, even though there is a lack of careful consideration of the health of the periodontal tissue and orthodontic treatment methods.

In adults, however, there is a lack of cancellous bone, limited blood flow, a structural change in bone volume, a lower alveolar marginal healing, and therefore difficulty in tooth movement, resulting in prolonged treatment, The frequency of alveolar bone uptake also increases. For these reasons, serious side effects may occur if the biologic changes and biomechanical problems that may occur during tooth movement are not fully understood.

Recently, it has become possible to treat periodontal tissue, which has been recognized as a problem in orthodontic treatment. Various orthodontic treatment methods have been developed so that adverse effects are reduced in orthodontic treatment of adults and successful orthodontic treatment becomes possible. Therefore, even though they are adults, the population who want orthodontic treatment is increasing.

The dental orthodontic treatment mentioned above is one of the generalized dental treatment areas as an effective alternative for improvement of function and prevention of periodontal disease, not a simple esthetic improvement, with the change of social awareness. Especially, as the proportion of adult orthodontic treatment increases, a therapeutic approach needs to be taken in a direction different from that of growing dental orthodontic treatment. In adult, growth of alveolar bone due to increase of density of alveolar bone, decrease of bone formation due to tooth movement, In some cases, it is difficult to obtain the same treatment results as the orthodontic patient.

Several orthodontic treatments have been developed to overcome these problems, including orthodontic treatment with surgery, orthodontic treatment with orthodontic mini-implants, orthodontic treatment with self-ligating brackets or custom brackets for individual patients.

Recently, Biocreative Orthodontics has been used for shortening the period of correction. To overcome the limitation of tooth movement, a jaw incision or jaw resection, or more specifically cortical resection, is performed. The cortical resection will be described in more detail as follows.

The alveolar bone surrounding the tooth and the palate of the palate (palate bone) are composed of two layers of fine cortical bone, which are the outer cancellous bone of the cancellous bone and the bone tissue.

The tooth movement needs to be accompanied by tooth movement for the orthodontic correction. Since the cortical bone is hard and acts as a resistance in the tooth movement, the cure time can be shortened by accelerating the tooth movement through the cortical bone resection.

For example, in order to accelerate the movement of teeth in dental orthodontics, or more specifically, orthodontic treatment, it is known that, as a part of the cortical resection, damage to the cortical bone (cortical bone) , Which is a method using a Regional Acceleratory Phenomenon (RAP) induced through selective cortical bone damage.

More specifically, when the cortical bone is damaged in such a manner that a hole is formed in a hard cortical bone or a groove is formed, the above-mentioned local healing promotion phenomenon is induced. In this process, the cortical bone injured area and the bone around the cortical bone are softened , Resistance to tooth movement is reduced according to the softening of the damaged area and the surrounding bone, and as a result, the effect of shortening the correction period can be obtained.

Ultrasonic tools or blades are used to damage the cortical bone more specifically than the jaw. However, since the blade penetrates the jaws due to the hammer of the medical hammer, the patient becomes fearful and it is difficult to precisely align / align the target portion. In addition, since the blade slides at the target portion, It is difficult to form a trail, excessive damage to the soft tissue may occur, and careful attention to the procedure is required.
