JVA (Joint Vibration Analysis)
A Very Simple Principle
Bio-JVA Joint Vibration Analysis is based on simple principles of motion and friction. When smooth surfaces rub together, little friction is created and little vibration. If these surfaces become rough, then friction and vibration are created when these surfaces interact.
How It Works
Human joints have surfaces which rub together in normal function. Smooth, well-lubricated surfaces in a proper biomechanical relationship produce little friction and little vibration. But surface changes, such as those caused by degeneration, tears, or displacements of the disk, generally produce friction and vibration. Different disorders can produce different vibration patterns or signatures. PC-assisted vibration analysis helps identify these patterns and helps your dentist distinguish among various TM disorders.
EMG ( Electromyography)
Beautiful Smiles and Healthy Muscles
Surface EMG is the worldwide standard method for recording muscle-specific activity in skeletal muscles. It has been proven reliable in numerous studies over many years and is a clinical procedure that can easily be performed in any dental office. This information is invaluable to the clinician who hopes to create beautiful dentistry that works with the patient’s physiology for optimum results.
Gain Confidence by Giving up HOPE?
SEMG is the only way to objectively measure the actions and reactions of the muscles of the head and neck. This provides clinicians with the ability to test their treatments and bite positions before finalizing the treatment position. With BioEMG II you can give up “HOPE” dentistry. Stop hoping your bite is right for your patients’ muscles, stop hoping your restorations will not lock in muscle spasm, start feeling the freedom and confidence that comes with objectively testing your patients’ muscles with BioEMG II.
Jaw Tracking (Electrognathography) equipment offers the ability to track jaw movements three- dimensionally to record the point of dysfunction so it can be corrected.
A headset is placed on the patient, and with a magnet inside his or her lower front teeth, a recording of the lower jaw movement is made. Jaw tracking is a completely non-invasive technique.
Making Occlusion an Objective Science
For years, dental occlusion had largely been a matter of guesswork for dentists. Articulation paper, waxes, pressure indicator pastes, etc. were all dentists had to assess and balance the forces of occlusion. Most of these methods are not sensitive enough to detect simultaneous contact, and none measure both biting time and force. Tekscan met the challenge by developing the T-Scan system. T-Scan’s grid-based sensor technology proved so successful that Tekscan has applied the same technology to hundreds of other applications, forming Tekscan’s Medical and Industrial divisions.
BioTENS is a compact, Ultra-Low Frequency, Transcutaneous Electrical Neural Stimulator (ULF-TENS). ULF-TENS delivers a precisely regulated, bilaterally simultaneous, rhythmic stimulus to both the masticatory and the facial muscles. Based on a patent issued in 1984, a single pair of electrodes (without the need for any ground) provides gentle stimulation, mediated* through the fifth (Vth) and seventh (VIIth) cranial nerves, such that the benefits are received by the entire masticatory and facial musculature.
Relax Those Muscles
When BioTENS is used to relax muscles prior to taking a clinical bite registration, it is possible to observe the effect of the ULF-TENS on the muscles by recording the electrical activity with an electromyograph (BioEMG II). The BioEMG II can show the levels of activity before and after the TENS pulsing. Many pain patients exhibit more muscle activity before pulsing and less activity after pulsing.
