摘要:
A pre-determined exciting force is imparted to a patient''s teeth to cause them to emit a measurable sound or radiation response. The response is picked up by a microphone located inside the oral cavity immediately behind the teeth, and then is conveyed to a frequency analyzer positioned near the patient. Optionally, a sound level recorder can be connected to the frequency analyzer so as to automatically record the sound spectra on preprinted recording paper. Since the emitted sound is a function of the frequency response of the teeth, which in turn depends upon the rheology and hence the health of the periodontium or teeth supporting structures, periodic checks of the teeth''s frequency response can provide a record of the changes in the patient''s periodontal health.

A light wave treatment instrument is disclosed and generally comprises a control unit operably coupled to a power source; a light source operably coupled to the control unit operable to deliver pulses of optical radiation; and a heart rate monitor operably coupled to the control unit, wherein the light source delivers pulses of optical radiation to an area of desired treatment synchronized to the heart beat determined by the heart rate monitor.
摘要:
The present invention relates to a torsional vibration resonance frequency measuring method and a novel amplitude transformer for assessing the stability of dental implants. In one example, a torsional vibration resonance frequency measuring method includes installing an amplitude transformer on a dental implant, energizing a torsional vibration mode, gathering resonance signals, and analyzing a resonance frequency. In another example, an amplitude transformer for measuring torsional vibration resonance frequency in a dental implant, includes an anti-rotary horizontal double-winged component and a central bolt. The central bolt is configured to closely connect with the inner threads of the dental implant, such that the amplitude transformer can integrate with the dental implant sufficient to vibrate as an integral structure under energizing.

摘要:
An apparatus for detecting the stability of a tooth in the gum or an implant in the body is constructed to include a holder for holding a test object to be examined, an impact device disposed at one side of the holder for striking the test object, causing the test object to produce vibrations, and sensor means disposed at one side of the holder for detecting the vibrations produced by the test object upon the striking of the impact device against the test object.
摘要:
A transducer assembly (10, 20, 80, 90) is used with an apparatus (100, 200) for detecting the stability of a bone implant (30). The transducer assembly uses one or more transducers to excite vibrations in said bone implant and to detect a response to the vibrations. A coupling (80) is used to detachably connect the one or more transducers to circuitry for driving the vibrations and detecting the response. A memory device (90) is provided within the transducer assembly. The memory device (90) can store one or more parameters read from outside of the transducer assembly via the coupling for controlling the use of the transducer.
