また歯の変位量のみを重視しているので歯周組織の性状
を解明したことにならないという欠点があった。Conventional technology Diagnosis of tooth mobility is indispensable for periodontal diseases, etc., and conventionally, diagnosis of tooth mobility is based on the feeling when the operator moves the tooth in the buccolingual direction or mesio-distal direction with tweezers or fingers. The method of judgment was generally used. However, this method has a drawback that the operator's experience and subjectivity are added to the method so that a sufficiently accurate judgment cannot be made. Also, after fixing the patient's head to the safe rest, push or pull the tooth with a pressure gauge, and the displacement of the tooth at that time is based on the left and right molars as a dental micrometer or dental. A method of making a quantitative diagnosis by measuring with a dial gauge for use was used, but this method requires that the patient be firmly fixed to the abutment table, and because the posterior tooth is used as a reference, only the front tooth is used. There were many shortcomings such as inability to diagnose. There is also a resonance frequency measurement method that applies vibration to obtain its response characteristics,
This method has many problems such as large-scale equipment, data reliability, and difficulty in fixing the exciter. Generally, the method of measuring the mirror using empirical feeling
The present situation is to use a method in which the degree of tooth vibration is classified into four stages from 0 degree to 3 degrees. However, this mirror measurement method has the drawback that it is greatly influenced by the subjectivity of the operator.
Moreover, since only the amount of tooth displacement is emphasized, there is a drawback that the properties of the periodontal tissue cannot be clarified.

The object of the present invention is to provide a diagnostic device for periodontal tissue, which is capable of diagnosing not only shaking of teeth but also strength and weakness of gingiva.

歯の動揺度に関連して減衰した加速度が検出される。Structure FIG. 1 is a block diagram for explaining an embodiment of the present invention, in which 10 is a treatment chair, 11 is an armrest, 20 is a patient, and at the time of diagnosis, the treatment chair is as shown. The patient's head is placed on the armrest base 11 in the inverted state. Reference numeral 1 denotes an acceleration detecting device, which is composed of a rigid rod-shaped member 1a that comes into direct contact with teeth and an acceleration detector 1b attached to an end of the rod-shaped member 1a. Reference numeral 2 is a vibrating device attached to the rear side of the armpit base 11. The vibrating is performed at a frequency of, for example, several tens to 100 Hz, and the vibrating force is adjusted by controlling the frequency and the amplitude. .. Specifically, an unbalanced weight motor drive, a solenoid vibrator drive using a spring system, or the like is used. Since the vibration applied by the vibrator 2 is finally transmitted to the tooth through the gingiva, if the speed detector 1 as described above is applied to the tooth to be diagnosed, the strength or weakness of the gingiva or the tooth is reduced. The decayed acceleration is detected in relation to the fluctuation degree of the.
この加振力は常に一定であることが好ましいが、実際に
は、患者が代った時などに変ってしまうことがあるの
で、そのような加振力の変化を校正して所定の加振力を
加えるために、例えば、上顎歯牙４を診断する時に頭蓋
骨６部の振動を検出し、この頭蓋骨６部の振動を基準に
して校正し、また下顎歯牙５を診断する時は下顎７部の
振動を検出し、この振動を基準として下顎の歯牙に加え
る加振力を校正する。It is preferable that this exciting force is always constant, but in reality, it may change when the patient is replaced. Therefore, such a change in the exciting force is calibrated and the prescribed exciting force is applied. In order to apply force, for example, when diagnosing the upper jaw tooth 4, the vibration of the skull 6 is detected and calibrated with reference to the vibration of the skull 6, and when diagnosing the lower jaw tooth 5, the lower jaw 7 The vibration is detected and the vibration applied to the teeth of the lower jaw is calibrated based on this vibration.
効果 以上の説明から明らかなように、本考案によると、前歯
以外の（横）奥歯の測定が可能、検査時の苦痛、いたさ
から解放、生体としての歯牙動揺に近い条件の測定が可
能、加振器が１個、１箇所であるため、同一条件で測定
可能の為、装置が小型である等の利点がある。更には、
加振器が安頭台の後側に予め取り付けられているので、
加振器の取り付け位置、取り付け状態が常に一定であ
り、更には、加振器の取り付けに気を配る必要もなく、
簡単に、しかも、常に一定した加振力を加えることがで
きる。また、患者の歯牙を直接打診しないので、患者に
苦痛を与えることはない。Effect As is clear from the above explanation, according to the present invention, it is possible to measure the (lateral) posterior teeth other than the anterior tooth, the pain at the time of examination, release from the pain, and the measurement of conditions close to tooth sway as a living body, Since there is one shaker and one place, it is possible to perform measurement under the same conditions, which is advantageous in that the device is small. Furthermore,
Since the shaker is pre-installed on the back of the Anto stand,
The mounting position and mounting state of the shaker are always constant, and furthermore, there is no need to pay attention to the mounting of the shaker.
It is possible to easily and constantly apply a constant excitation force. Moreover, since the patient's teeth are not directly percussed, the patient is not injured.
