Measured Matters

Our Purpose: Diagnosis!

To train dental health professionals in objectively measurable and scientifically validated occlusal/bite and TMJ/D diagnostic and treatment solutions.
We believe in measuring bite and “TMJ” problems whenever possible. Many times the TIMING of your bite is out of alignment and that IS the root cause of your “TMJ” problems. Sometimes though, things are more complex than just your bite being off… Neural Occlusion Screening (NOS) greatly aids a practitioner in identifying the root cause(s) of your confounding “TMJ” and orofacial pain troubles, as they relate to your bite, muscles, ligaments, cartilage, bone, and the neurology within your chewing complex.

CNO protocols assist in objectively finding a proper diagnosis (or diagnoses), followed by predictable treatment protocols, to address the root of your occlusal/bite issues. TMJ issues are rarely psychological, though they ARE “in your head”; ligaments, muscles, cartilage, the timing and force between your teeth, bone, inflammation, and much, much more - all located within your head and neck!

What is "TMJ"?

TMJ is just anatomy. TMD is an umbrella term that involves orthopedic, muscular, neurological, and/or dentally related issues.

CNO Founder’s Letter

Dr. Nick Yiannios

Occlusal, orofacial and TMD pain has long demanded the attention of both medical and dental professionals. When a physician or dentist becomes involved in this field, he or she begins to appreciate the fact that the purviews involved cross the manmade boundaries, since essentially, everything in the human body is connected in some way, shape or form…Continue Reading

How Neural Occlusion Screening Works

Neural Occlusion screening involves the utilization of hi-tech objective technologies, knowledge, and protocols to ascertain whether or not a patient possesses a proper bite and stable and adapted TMJ's, and/or if their problem(s) arise from other sources.


We believe in measuring “TMJ” problems whenever possible. Many times the TIMING or the alignment of your bite is incorrect and that IS the root cause of your “TMJ” problems.

What We Measure

Force & Time (T-Scan)

This device called a T-Scan reads the force and timing of your bite. Placing this into the patient’s mouth it is possible to objectively record and measure the bite.


Electromyography (EMG) is an electrodiagnostic medicine technique for evaluating and recording the electrical activity produced by skeletal muscles in microvoltages. CNO uses the EMG.


Allows us to look inside your teeth. Sometimes your past dental work is responsible for your TMD issues, or at least a contributing layer.

Ice Water Swish

Frictional Dental Hypersensitivity (FDH) can occur when the patients muscles are overworking due to a misaligned bite. The patient with a TMD issue solely due to overactive muscles from a bite issue will typically have hypersensitive teeth that shows up when they are challenged with the ice water swish. Once the bite alignment is corrected, the sensitivity will typically go away. There are neurological reasons for this that are not fully understood, which may relate to the overactivity of the sympathetic branch of the autonomic nervous system.


Joint Vibration Analysis is a screening tool of the TMJ cartilage. JVA 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, as would be the case when the TMJ cartilage is damaged relative to the bone in one or both joints, then the friction and vibration that is created when these surfaces articulate would show up as an aberration in the JVA readings.


CBCT scan, also called X-ray cone beam computed tomography, is a low-radiation way of studying the bony jaw bone and the skull, objectively elucidating spacing between these bones as well as growth and development issues. It is also very effective at identifying degenerative and arthritic changes that might be taking place within the TMJ’s as well.


Magnetic Resonance imaging uses magnetic pulses rather than ionizing radiation to study cartilage, fluid, and fat content within both TMJ’s. An extremely useful tool, MRI often identifies problems that would go completely unnoticed otherwise.

Categorize Patient

After all scans and measurements are complete, patients are then categorized.

Digitally Directed “Alignment”, IF Indicated

Measured Anterior Guidance Development (MAGD) therapy is a bite/occlusal adjustment procedure used in patients that possess stable and adapted temporomandibular joints (TMJs). Objective confirmation of stable & adapted TMJs leads to predictable outcomes regarding all forms of dental treatment!
When back teeth contact/touch too long in TIME during function, research has shown repeatedly for decades that this neurologically overstimulates muscular contraction within the chewing complex. Many of these muscles, when overworked, become very fatigued and painful, resulting in unexplained headaches and tension within the head and neck. In a practical sense, muscles that overwork chronically can lead to not only broken teeth, but failing dental work as well!
A precise and objective, digitally directed “alignment” of the way the teeth relate to one another over TIME, can reduce this overstimulation of the muscles (in patients with objectively confirmed TMJ's), leading to not only a reduction in painful symptoms, but in the likelihood that dental work will not fail over time as well!
Based upon three decades of evidence-based research by Dr. Robert Kerstein and others, computer-directed occlusal adjustments have repeatably been shown to improve many cases of TMD pain of occlusal genesis, specifically in cases which possess relatively orthopedically stable and adapted TMJs. In such cases, removing pathological excursive occlusal contacts based upon precise and digitally-identified contacts in the dynamic occlusion will often palliate chronic muscular TMD pain, and will often simultaneously allow the dental practitioner to improve the integrity of not only the dentition, but properly placed restorative treatments and orthodontic movements as well. Those doctors that have trained up to CNO level 3 (MCNO) are particularly adept at diagnosing and treating appropriate cases such as these.

What others are saying

Neural Occlusion Screening (NOS) is revolutionizing TMD diagnosis and treatment, and improving the likliehood of successful dental treatment outcomes! Check out what patients and doctors are saying about it!

"Hello from Calgary, Alberta! It's been a few weeks since my computer-guided bite treatment, and I have to tell you that you've changed my life! It took a few days for my jaw to settle out, but since then, I haven't had any jaw pain. I continue to sleep without my splint, and although I had a couple of pressure points early on, my teeth do not hurt at all. My muscles still seem tight when I wake up (I might still be clenching at night), but my joints do not cause me any pain. This is very different from before treatment, when a sore jaw was a daily and significant occurrence. Also, I have again tried the dreaded "ice water test," and while I was still an 8/10 in your office right after the treatment, I would now put my pain at a 0/10. It feels cold, certainly, but not at all painful. When I first tested it out last week I couldn't believe it, and had to keep swishing to see if it was true! So amazing. So needless to say, I am incredibly happy with the results of my digital bite alignment. I can't believe the difference you have made in my life, and I can't possibly thank you enough."

– Vikki-a patient   Calgary, Alberta

“Because the measured linkage of force and muscle activity in DTR is a critical component of treating many occluso-muscular disorders, I was happy to be able to take the Certification exam to ratify that the learning I had undertaken would enable me to serve my patients' best interests.”

– Peter Barnett, DMD, FCNO   Plano, TX

"The motto says it all: "Measured Matters". Dentistry has wandered thru the wilderness of solving oro-facial pain for our patients, and the CNO concepts are a huge step forward in our ability to help the people we serve. It is an exciting time for dentistry!"

– Rick Coker DDS, FCNO   Tyler, TX

"Before the computerized bite alignment, my mouth was telling my brain that things weren’t right, but I didn’t know what to do about it. Several months after having gone through the treatment, I have nothing bad to say about it! If things keep going the way they are, I’m going to be a very happy person! The things that I’ve done w/ this disability… imagine what I’m going to do without it! I’m going to take over!" His case study: https://youtu.be/AWv-1-_JhKQ

– Taner-a patient   Istanbul, Turkey

“Nobody in my area, not one dentist, could get my bite right. Every time I had dental work done, the bite was shifting all over to the point that I had teeth banging from my front teeth to my back teeth. Jaw pain, headaches in the back of my head, neck and shoulder pain; all of that has improved since getting my bite balanced to the way it was supposed to be!” Her case study: https://youtu.be/rJEN8CoqGTA

– Darleen-a patient  Michigan, U.S.A.
