Description

Photoacoustic stimulation device for oral use{Photoacoustic Simulus Apparatus for Oral Cavity}

The present invention relates to a photoacoustic stimulation device for oral cavity, and more particularly, by using a photoacoustic phenomenon that occurs when a laser is applied to a living body tissue, promotes osseointegration of the pubis, periodontal and gums, promotes blood circulation, and inflammatory reactions. It relates to a photoacoustic stimulation device for oral cavity to solve.

In general, a dental implant procedure refers to a dental procedure that restores the original function of a tooth by embedding an implant that is a substitute for a lost natural tooth in the alveolar bone of the upper and lower jaw. Dental implants are the most effective method for improving mastication function for patients with tooth defects, and the number of procedures is rapidly increasing with the recent increase in the elderly population.

During dental implant procedure, an implant fixture is placed on the upper or lower jaw where the tooth is defective. In this case, the direct organizational and functional connection between the bone tissue and the implant fixture is called Osseointegration, and such osseointegration must be done well. Can be successful and its lifespan can be long.

Since the period for regeneration and osseointegration of the implant fixture and the alveolar bone takes about 3 to 6 months, there is a problem that a considerable time is required for the implant procedure. Therefore, various methods have been proposed for promoting osteosynthesis between the surface of the implant fixture and the bone tissue of the alveolar bone. For example, a method of increasing the contact area between the surface of the fixture and bone tissue has been developed and used by coating a fine powder on the surface of the fixture or sanding the surface to form fine irregularities on the surface. However, a fixture coated with a fine powder on the surface has a disadvantage in that the powder adhered to the surface falls off, and a fixture treated with sanding has a limitation in increasing the surface area because the depth of the irregularities cannot be increased beyond a certain limit. In order to solve this problem, a bone fusion promoter has been proposed to promote bone fusion of the implanted part.

1 is a view showing a conventional bone fusion promoter. Referring to FIG. 1, the conventional bone fusion promoter is for promoting bone fusion of an implanted portion, and includes a probe 10 having a concave receiving portion therein; A vibrator 20 accommodated in the receiving unit and configured to generate ultrasonic waves by vibrating by receiving a frequency; It includes a handle 30 extending to one side of the probe 10 to be gripped by a user's hand and having a passage formed therein so that an electric wire is installed therein. In addition, the user holds the handle 30 and inserts the probe 10 into the oral cavity to bring the vibrator 20 into contact with the implanted tooth, and then operates the body (not shown) so that the vibrator 20 generates ultrasonic waves. So that the treatment is performed.

However, in this prior art, since the vibrator directly connected to the wire is in direct contact with the teeth of the human body, a weak current flows into the human body, and there is a problem that there is a risk of an electric shock accident.
