Description

  The present invention relates to an ultrasonic treatment apparatus used when a dental treatment is performed using an implant.

  Conventionally, there has been known a method of embedding a pin-shaped artificial dental root called an implant in an upper jaw or a lower jaw and screwing an artificial crown into a screw hole on the upper surface of the implant. In this method, an artificial dental crown is attached after the implant is embedded in the bone and after the implant has been integrated with the bone tissue. In this case, it is essential to use a temporary denture during the period until the implant is integrated with the bone tissue, and until now, there was no other choice but to leave it to natural healing, so a tissue is formed between the implant and the bone. Until this time, the patient is inconvenienced.

In order to promote healing after such an implant treatment, for example, Patent Document 1 discloses a device for applying physical therapy to an affected area. According to such an invention, there is disclosed an ultrasonic therapy apparatus that promotes integration of an implant and bone tissue by applying ultrasonic vibration to an affected area.

  However, in general, the vibration surface of the vibrator that gives such ultrasonic vibration is a flat surface, whereas the portion subjected to the implant treatment has irregular irregularities. For this reason, since it is difficult to closely adhere the vibration of the vibrator to the portion where the implant treatment has been performed, there is a problem that it is difficult to efficiently propagate the ultrasonic vibration to the portion where the implant treatment has been performed. In addition, it is conceivable that the shape of the vibration surface of the vibrator is formed following the shape of the implant treatment part. However, the surface shape of the implant treatment part may change according to the healing of the affected part. Whenever the shape changes, it is not realistic to mount a vibrator having a changed vibration surface shape.

  This invention is made | formed in view of the said situation, Comprising: It aims at providing the ultrasonic treatment apparatus which can propagate an ultrasonic vibration to an implant treatment part reliably and efficiently.

  In order to achieve the above object, according to the present invention, one or more housings disposed in proximity to a portion of an oral cavity subjected to an implant treatment, and a vibrator disposed in the housing, A holding portion provided in a part of the housing and adjacent to the portion subjected to the implant treatment, and a portion interposed between the holding portion and the portion subjected to the implant treatment, and a part thereof It is supported by a holding part, deforms following the shape of the outer surface of the portion subjected to the implant treatment, closely contacts the portion subjected to the implant treatment, and the vibration transmitted from the vibrator is subjected to the implant treatment. There is provided an ultrasonic therapy apparatus characterized by comprising a vibration transmitting material that efficiently transmits to a portion.

  The vibration transmission material may be composed of a transmission medium that propagates ultrasonic waves and a holding body that holds the transmission medium. The transmission medium only needs to be deaerated. The degassing process may be heating or evacuation of the transmission medium. It is sufficient that a diffusion material for diffusing ultrasonic waves is dispersed in the transmission medium. The holding body may be a bag that wraps the transmission medium, a porous body that impregnates the transmission medium, a brush that holds the transmission medium, or a gel or sol that changes viscosity including the transmission medium.

  The housing may be locked to an engagement member adapted to engage with at least one of the teeth adjacent to both sides of the implant-treated portion. It is only necessary that a plurality of the casings are provided apart from each other and a connecting member for connecting the casings is provided. A vibration absorbing member may be provided in a region other than the holding portion of the housing. A lead wire for supplying an ultrasonic signal to the vibrator may be provided in the casing.

  According to the present invention, the vibration transmitting material that is made of a flexible material and efficiently transmits ultrasonic waves is in close contact with the portion subjected to the implant treatment, and the vibration transmitted from the vibrator is subjected to the implant treatment. An efficient and reliable transmission to the gums is possible. Accordingly, it is possible to reliably and efficiently propagate the ultrasonic vibration to the implant treatment part. Generation of bone tissue around the implant can be surely promoted, and the treatment time can be shortened.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a partial cross-sectional perspective view showing an ultrasonic treatment apparatus of the present invention and a state in an oral cavity when the ultrasonic treatment apparatus is attached to a gum. Moreover, FIG. 2 is sectional drawing which shows a mode at the time of attaching such an ultrasonic treatment apparatus to a gum. In FIG. 2, 1 is a gum after extracting a tooth, 2 is a bone, 3 is a gum, and 4 is an epidermis. 5 is an implant as an artificial tooth root, and is embedded until it reaches the bone 2 from the gum 1 as shown. A screw hole 5 a into which an artificial crown (not shown) is screwed is provided on the upper surface of the implant 5. 2A is a bone tissue generated around the implant 5.

  1 and 2, reference numeral 6 denotes an ultrasonic therapy apparatus according to the present invention, which includes a housing 7, a vibrator 8 supported by the housing 7, and a vibration transmitting material 21. The housing | casing 7 should just be formed from resin which does not interfere even if it inserts in an intraoral area. An engaging portion 22 is integrally formed at one end of the housing 7. By fitting the engaging portion 22 into the engaging groove 24 formed in the engaging member 23, the ultrasonic treatment device 6 can be fixed to face a predetermined portion (treatment portion) of the gum 1. .

  The engaging member 23 includes two fixing tools 10 and 11 and an engaging body 25 in which the above-described engaging groove 24 is formed. The fixing tools 10 and 11 and the engaging body 25 are formed in the oral cavity. It may be formed from a resin that does not hinder the insertion. The fixtures 10 and 11 have a coronal shape so as to cover the adjacent healthy teeth 12 and 13, respectively, and are integrally connected to the engaging body 25. The fixtures 10 and 11 may be molded with resin or the like according to the shape of the teeth 12 and 13.

  FIG. 3 is a side sectional view of the ultrasonic therapy apparatus. In the ultrasonic therapy apparatus 6, as described above, the vibrator 8 and the vibration transmission material 21 are supported by the housing 7. The vibrator 8 generates ultrasonic waves on the flat vibration surface 8a by vibration. The ultrasonic wave generated from the vibrator 8 may be in a frequency band that promotes the generation of bone tissue around the implant 5. A lead wire 14 for supplying an ultrasonic signal to the vibrator 8 may be appropriately derived from the vibrator 8.

  The vibration transmitting material 21 is supported on the housing 7 by a holding portion 7 a formed integrally with a part of the housing 7. One side 21a of the vibration transmitting material 21 is in close contact with the vibration surface 8a of the vibrator 8, and the exposed surface 21b is exposed. The vibration transmitting material 21 is formed of a material having at least an exposed surface 21b flexible, for example, a sol using water as a medium. The peripheral surface other than the one surface side 21a of the vibrator 8 may be covered with a vibration absorbing member.

  The material constituting the vibration transmitting material 21 is preferably a substance that can efficiently transmit the ultrasonic waves generated by the vibrator 8 from the one surface side 21a toward the exposed surface 21b, for example, a substance mainly composed of water. The exposed surface 21b is a flexible material, for example, the above-described sol using water as a medium, wherein agar, gelatin, pectin or the like dispersed in water is used alone or is contained in a bag. Can be mentioned. Further, a brush holding water or a sponge containing water is preferable. These may be configured so that water transmitting ultrasonic waves does not flow out even by ultrasonic vibration.

  Such a substance that can efficiently transmit ultrasonic waves (hereinafter referred to as a medium substance) may be other than water. The medium substance is preferably liquid at room temperature from the viewpoint of flexibility. Such a medium substance is preferably subjected to a deaeration process for removing the contained gas. Normally, when ultrasonic waves are applied to a liquid such as water, a dissolved gas such as air is generated as bubbles. When such gas is generated, the ultrasonic wave is attenuated and the shape maintenance of the vibration transmitting material is impaired. For this reason, bubbles are not generated when ultrasonic waves are applied by removing the gas contained by performing a deaeration process. Examples of the deaeration treatment include deaeration by heating and evacuation under a vacuum environment.

  For example, it is also preferable to disperse a diffusion material for diffusing ultrasonic waves in a sol using water as a medium constituting the vibration transmission material 21 described above. Such a diffusing material plays a role of diffusing the ultrasonic waves applied from the vibrator into the inside of the vibration transmitting material without deviation, and allows the ultrasonic waves to propagate uniformly within the exposed surface from which the ultrasonic waves are emitted. As such a diffusing material, powders and foils such as aluminum and copper may be dispersed.

  In this way, by forming at least the exposed surface 21b of the vibration transmitting material 21 with a flexible material, the shape of the side surface of the gum 1 after extraction of the tooth, which is a portion subjected to the implant treatment shown in FIG. Thus, the exposed surface 21b is deformed and is in close contact with this portion (see FIG. 4). As a result, even if the vibration surface 8a of the vibrator 8 is a flat surface, the vibrator 8 is made of a flexible material and is in close contact with the implant-treated portion via the vibration transmitting material 21 that efficiently transmits ultrasonic waves. The vibration transmitted from the vibrator can be efficiently and reliably transmitted to the gum 1 subjected to the implant treatment. As a result, it is possible to efficiently promote the generation of the bone tissue 2A around the implant 5.

  FIG. 5 shows some configuration examples of the vibration transmitting material. FIG. 5 a shows an example in which the vibration transmission material 31 is composed of a liquid transmission medium 32 and a bag-like holding body 33 that accommodates the transmission medium 32. The transmission medium 32 may be water or a medium in which a gelling substance such as gelatin that adjusts viscosity is added to water. Examples of the holding body 33 include a flexible resin bag, a metal thin film bag, and the like. By preliminarily transmitting the transmission medium 32, the holding body 33 does not swell or break due to the generation of bubbles by ultrasonic waves. By virtue of the vibration transmitting material 31 composed of such a transmission medium 32 and a bag-like holding body 33 that accommodates the transmission medium 32, the vibration transmitting material 31 can be brought into close contact with the irregular gums, and the ultrasonic waves generated by the vibrator 8 can be efficiently used. Can be transmitted to the gums.

  FIG. 5 b shows an example in which a water-containing sponge 42 (holding body) is used as the vibration transmission material 41. The sponge 42 contains water as a transmission medium. Such water may be any water to which a gelling substance such as gelatin for adjusting the viscosity is added in order to prevent outflow. By the flexible sponge 42 containing such a transmission medium, the vibration transmission material 41 is brought into close contact with the irregular gum, and the ultrasonic wave generated by the vibrator 8 can be efficiently transmitted to the gum.

  FIG. 5 c shows an example in which the vibration transmission material 51 includes a liquid transmission medium 52 and a brush (holding body) 53 that holds the transmission medium 52. The transmission medium 52 may be any medium in which a gelling substance such as gelatin that adjusts viscosity is added to water. The brush 53 may be any brush in which a large number of flexible resin hairs are implanted. By holding the transmission medium 52 having viscosity on the brush 53, the vibration transmitting material 51 can be brought into close contact with the irregular gum, and the ultrasonic wave generated by the vibrator 8 can be efficiently transmitted to the gum.

  Next, a method for performing treatment using the ultrasonic therapy apparatus 6 according to the first embodiment described above will be described. As shown in FIG. 1, for example, two implants 5 are embedded after two adjacent teeth on the gums are extracted. Here, the fixing members 10 and 11 of the engaging member 23 are put on the teeth 12 and 13, respectively, and the engaging member 23 is attached to the oral cavity so as to cover the implant 5.

  Next, the engaging portion 22 of the housing 7 of the ultrasonic therapy apparatus 6 is inserted into the engaging groove 24 formed in the engaging body 25 of the engaging member 23. Then, the vibration transmission material 21 of the ultrasonic treatment device 6 hits the side surface of the gum 1 after the teeth are extracted. The flexible vibration transmitting material 21 is deformed following the shape of the side surface of the gum 1 and is in close contact with the gum 1. When the vibrator 8 is operated, the ultrasonic wave generated by the vibrator 8 is efficiently and reliably transmitted to the gum 1 through the vibration transmitting material 21 that is deformed and closely adheres to the outer shape of the gum 1. . In this way, an ultrasonic wave is efficiently given around the implant 5 and the generation of the bone tissue 2A can be promoted. By using the flexible vibration transmitting material 21, the vibration transmitting material 21 can be brought into close contact with the gum 1 at any stage even if the outer surface shape of the gum 1 changes with the generation of the bone tissue 2 </ b> A.

  In addition to these embodiments, a plurality of housings having flexible vibration transmission materials are provided, and ultrasonic waves are applied to these vibration transmission materials by one vibrator so as to be in contact with two or more implant portions. Such a configuration may be used.
