Advanced GNM K7 Scan Interpretation & Clinical Application

Before You Read Another Word — Ask Yourself

• Are you taking scans just because you think you need them for records, but really don’t know what they mean clinically?
• Are you ignoring certain scans because no one ever taught you why they matter?
• Do your EMG readings raise more questions than answers?
• Do you understand the critical difference between diagnostic scans and treatment scans?
• Have you stopped looking closely at certain scan recordings — not from laziness, but because they simply haven’t made clinical sense?

If any of these hit close to home, you are not alone. No one has taught you how to make the occlusal connection to each and every K7 scan — so that each scan makes clinical treatment sense. This course was built for exactly this moment.

Standard neuromuscular training fixates on one goal: lower the EMGs. But optimal occlusion is far more complex than a single metric. Dr. Chan’s curriculum goes beyond low-EMG patterns to reveal the full clinical picture hidden inside your K7 data. You will learn to read and interpret:

• CMS (Computerized Mandibular Scanning) — trajectory deviations, arc-of-closure anomalies, and what mandibular movement patterns reveal about structural and muscular health
• EMG patterns — not just high vs. low, but the quality of muscle balance, coordination, and what true physiologic rest actually looks like
• ESG (Electro-Sonography) — joint sound analysis in clinical context, including advanced FFT interpretation for TM joint diagnosis
• Pre- and post-TENS scan deltas — understanding what changes, what doesn’t, and precisely what that means for your diagnosis
• Serial scan interpretation — tracking treatment progress objectively so you know your case is stable before you restore it

Beyond high versus low, what do these EMG patterns indicate occlusally — normal or abnormal? Knowing the difference directly impacts the way the clinician implements treatment to get the patient stable.

“If you don’t understand how to record the data properly, you’ll get faulty data, draw the wrong clinical conclusions, make the wrong decisions — and end up with failed occlusal and TMD treatment.” — Dr. Clayton Chan

No other course in the world addresses K7 scan interpretation with this level of clinical breadth and specificity.

Level 8 covers every K7 scan — Scans 2 through 19 — because every scan means something diagnostically. No other training program in the world covers this breadth with this level of clinical specificity.

“Every K7 scan means something diagnostically. If you don’t interpret the scans properly, you can miss the diagnosis.”

When the EMGs rise after 45–60 minutes of Dental TENS, most K7 clinicians do not know what it means — and many simply look away. The OC-trained dentist reads Scan 9 against Scan 10 and knows exactly what the muscles are reporting. Interpreted correctly, these 8-channel EMGs give clear direction on precisely what to address occlusally to bring the readings back to normal — the cervical group included. There is no need to avoid the cervical group EMGs; these are very important diagnostic findings, indicating what the dentist needs to do occlusally.

The K7 clinician must know what the upward and downward pulse patterns mean, since these patterns objectively document the condition of the patient’s mandibular position as well as the cervical muscle status. It is these tracing details that affect the clinical decision-making on how best to take and record an optimized bite registration. With this awareness, follow-up visits can be reduced and treatment time shortened.

Without knowing how to interpret joint vibration sound patterns on K7 Scan 15 ESG, a clinician never realizes that joint derangement sound patterns can be resolved and normalized. Most clinicians today ignore joint sounds altogether, and do not believe a dentist can normalize degenerative joint disease. Interpreting these objective measurements properly is precisely what makes that quality of treatment outcome possible.

Do you know what these EMG, CMS and ESG patterns mean? Are your patients getting stable? Are the musculoskeletal occlusal signs and symptoms diminishing — or are they being ignored?
