Abstract

An ultrasonic therapy device comprises two bodies and two holding members. The body, at the inner face of which an oscillator is embedded, covers an affected area into which implant fixtures are embedded. The holding member which holds the body has a shape of a crown which covers teeth next to the affected area. Two teeth were removed from the affected area into which two implant fixtures are embedded. Each of the bodies covers the affected area between the teeth which is covered by the holding members so that the bodies are exactly fixed in an oral cavity. In this state, it is possible to accelerate osteogenesis around the implant fixtures by supplying an ultrasonic signal from an external driver to the oscillator.

Claims

1. An ultrasonic therapy device comprising an oscillator which is arranged in a vicinity of an affected area in an oral cavity where an implant fixture is embedded and which outputs ultrasonic wave to said affected area.

2. An ultrasonic therapy device according to claim 1, comprising at least one body which is arranged in the vicinity of the affected area where the implant fixture is embedded, an oscillator which is arranged at an inner face of the body, and a pair of holding member which is arranged at side faces of the body and cover teeth next to the affected area.

3. An ultrasonic therapy device according to claim 1, comprising at least one body which is arranged in the vicinity of the affected area where the implant fixture is embedded, the oscillator which is arranged in an inner face of the body, and a pair of engaging members which is arranged at side faces of the body and elastically engage with teeth next to the affected area.

4. An ultrasonic therapy device according to claim 2, wherein, a plurality of bodies is arranged so that one of the bodies is separated to the other of the bodies and is connected to the other of the bodies by a connecting member.

5. An ultrasonic therapy device according to claim 2, wherein, the plurality of the ultrasonic therapy devices are connected to each other.

6. An ultrasonic therapy device according to claim 1, comprising at least one body which is arranged in the vicinity of the affected area where an implant fixture is embedded, the oscillator which is arranged at an inner face of the body, and a mounting member on which said body is mounted and which is arranged so as to cover all teeth in a maxilla or a mandibula.

7. An ultrasonic therapy device according to claim 1, comprising not less than one body which is arranged in the vicinity of an affected area where an implant fixture is embedded, the oscillator which is arranged at an inner face of the body, a headgear which a patient wears on the head, an elastic member which elastically holds said oscillator in the vicinity of said affected area.

8. An ultrasonic therapy device according to claim 2, wherein an vibration absorbing member which absorbs a vibration of the oscillator is arranged on any part of a surface of an oscillator except for a surface which faces said affected area.

9. An ultrasonic therapy device according to claim 2, wherein a wire through which an ultrasonic signal is supplied is arranged in said oscillator.

10. An ultrasonic therapy device according to claim 1, comprising at least one body which is arranged in the vicinity of an affected area where an implant fixture is embedded, a supporting member comprising a concavity having a shape relative to an uneven area of the mouth of a patient.

11. An ultrasonic therapy device according to claim 10, wherein an vibration absorbing member which absorbs a vibration of the oscillator is arranged on any part of a surface of an oscillator except for a surface of said uneven area of the mouth of a patient.

12. An ultrasonic therapy device according to claim 10, wherein a wire through which an ultrasonic signal is supplied is arranged in said supporting member.

13. An ultrasonic therapy device according to claim 1, wherein said oscillator is arranged in a bead member in which dentures are arranged and which is held in a human oral cavity.

15. An ultrasonic therapy method according to claim 14 wherein said ultrasonic is radiated by the ultrasonic therapy device of claim 1.

19. An ultrasonic therapy method according to claim 14 wherein said ultrasonic waves are emitted by the ultrasonic therapy device of claim 10.

20. An ultrasonic therapy method according to claim 14 wherein said ultrasonic waves are emitted by the ultrasonic therapy device of claim 13.

14. An ultrasonic therapy method comprising a step of embedding an implant fixture in a patient and a step of emitting ultrasonic waves to the patient.

16. An ultrasonic therapy method according to claim 14 wherein said ultrasonic wave are emitted by the ultrasonic therapy device of claim 2.

17. An ultrasonic therapy method according to claim 14 wherein said ultrasonic waves are emitted by the ultrasonic therapy device of claim 7.

18. An ultrasonic therapy method according to claim 14 wherein said ultrasonic waves are emitted by the ultrasonic therapy device of claim 8.
