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 “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 orofacial 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

Orofacial and TMD pain has long demanded the attention of 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 a combination of hi-tech objective technologies and knowledge 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


Categorize Patient

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

CNO Patient Types


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 (TMJ’s). Objective confirmation of stable & adapted TMJ's leads to predictable outcomes regarding restorative dentistry &/or TMD therapy!


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, DTR therapy does not involve the usage of splints, medications, injections, lasers, chiropractic therapy or other temporary adjuncts. DTR addresses what is often the genesis of the problem that causes the chewing muscles to overwork; excessive contact of posterior teeth, over passing TIME.  MAGD is essentially DTR therapy on steroids, in that the TMJ's and the influence that the joints impart upon the occlusion have been objectively measured before the initiation of treatment.  In other words, the joints and their influence upon the occlusion are taken into consideration with MAGD, whereas they are not with DTR therapy.  Those doctors who have trained through CNO Level 3 have demonstrated that they possess intimate knowledge about the TMJ's and are capable of performing MAGD therapy after objectively imaging the TMJ's.

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!


“Because the measured linkage of force and muscle activity in DTR is a critical component of treating 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, FCNOPlano, 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, FCNOTyler, TX


"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 DTR treatment. I can't believe the difference you have made in my life, and I can't possibly thank you enough." Her case study:

– Vikki-a DTR patientCalgary, Alberta


“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:

– Darleen-a DTR patientMichigan, U.S.A.


"Before doing DTR 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 done DTR, 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:

DOCTORS - Get CNO Certified.

Positively Change Lives.

As a CNO-trained health professional, you will be well-suited to identify, diagnose, and predictably address not only common restorative, orthodontic, and implant interventions, but many instances of confounding bite and TMD issues as well. The higher your level, the better suited you will be to consistently diagnose and treat many occlusal and TMD conditions, resulting not only in a more rewarding experience for you and your patients, but also an ethical, practical, and ubiquitously needed skill set which will set your practice apart from the rest!

Practitioners who have passed the various certification levels and who possess an active CNO annual membership will be listed in the CNO "find a doctor" database, used by patients to find a CNO trained practitioner.
