Abstract

<P>PROBLEM TO BE SOLVED: To enable the effective separation between a bone and a mucosa by expanding a pointed head section of a dental vibration tip in a conical shape and concentrating the vibration at the surrounding section of the pointed head. <P>SOLUTION: The dental vibration tip 10 is removably attached to a vibrator 1 by threaded sections 1a and 10a and is vibrated by the vibrator 1. The pointed head section 10d of the dental vibration tip 10 is expanded in the conical shape and the vibration is effectively concentrated at the surrounding section of the pointed head 10f. The bone and the mucosa are separated by inserting the pointed head section 10d between the bone and the mucosa and vibrating it. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a dental tip, and more particularly to a tip suitable for use in a dental treatment by a socket lift method to insert a tip of a tip between a bone and a mucous membrane to separate the bone and the mucous membrane. .

  In dental treatment, artificial denture implants that can be bitten with a feeling close to your own teeth have been used recently, but when the height of the bone in which the implant is to be inserted is not high enough, the socket lift method can be used. Raising the cave is done. With these new techniques, even those with a constitution or condition in which an implant could not be used a long time ago can now be used for implant treatment.

  The biggest factor that prevents implants is the case where the amount of bone that serves as the foundation of the implant is small, and the amount and quality of the bone under the teeth is a major factor in the availability of the implant. For example, when an implant is placed in the maxillary back teeth, there is a cavity called the maxillary sinus in the bone, but the amount of the bone, particularly the bone height, is required. However, if teeth are lost due to periodontal disease or the like, in many cases, the bone mass is reduced, and the bone height necessary for treatment cannot be maintained.

  As described above, even when the bone height necessary for the treatment is insufficient, if the treatment for increasing the bone mass is performed in advance, the implant treatment can be performed. The socket lift method is a tool called an osteotome that lifts the mucous membrane at the bottom of the maxillary sinus, inserts a bone filling material into the space, and inserts an implant into the resulting space, with almost no drilling of the jaw bone.

  The present invention intends to provide a vibration chip suitable for use in peeling the bone and mucous membrane while inserting the tip between the bone and mucous membrane when performing the socket lift method in the dental treatment as described above. Is.

  The present invention is a dental tip that is detachably attached to a vibrating body and is vibrated by the vibrating body, wherein the tip of the tip is spread in a trumpet shape.

  Since the tip of the dental tip according to the present invention has a trumpet shape, the vibration can be concentrated on the periphery of the tip, and the bone and mucous membrane can be more effectively separated.

  FIG. 1 is a view for explaining an example of a dental tip according to the present invention, FIG. 1 (A) is a side view showing the entire structure, and FIG. 1 (B) is a cross-sectional view taken along line BB in FIG. 1 (A). In the figure, 1 is a vibrating body (a known vibrating body such as an ultrasonic vibrating body, an air vibrating body, a motor vibrating body, etc.), 10 is a chip according to the present invention, and 10a is a threaded portion 1a of the vibrating body 1. A screw part 10b for screwing with the wrench engages a wrench used when screwing the chip 10 to the vibrating body 1, and a wrench is engaged with the wrench engagement part 10b. Then, the tip 10 is rotated to fasten and fix the screw portion 10 a of the tip 10 to the screw portion 1 a of the vibrating body 1.

In FIG. 1, reference numeral 10 c denotes a vibration transmitting portion, and the tip portion 10 d of the vibration transmitting portion 10 c vibrates in parallel (in the direction of the arrow) with respect to the paper surface when the vibrating body 1 is driven. The tip portion 10d is formed in a trumpet-shaped recess 10e as shown in a cross-sectional view in FIG. 1B, and the vibration transmitted from the vibrating body 1 is concentrated on the edge portion 10f of the recess 10e. It has become.
In addition, although the example which made the front-end | tip part 10d circular was shown in FIG. 1, you may make it not only circular but an ellipse and other desired shapes and providing a recessed part in a center part.

  FIG. 2 is a configuration diagram of a main part for explaining an example of a socket lift method in dental treatment. As shown in FIG. 2A, a hole 20a is formed in the bone 20 to expose the mucous membrane 21, and FIG. As shown in FIG. 2B, the tip 10d of the tip 10 is inserted between the bone 20 and the mucous membrane 21 through the hole 20a, and the vibrating tip 10 is vibrated in the direction of the arrow as shown in FIG. The edge portion 10f of the distal end portion 10d is vibrated to peel off the bone 20 and the mucous membrane 21.

It is a figure for demonstrating one Example of the dental chip | tip by this invention. It is a figure for demonstrating the example which peels a bone and a mucous membrane using the dental chip | tip by this invention.
