ATTENTION!There are no teeth in this lecture!There are no specific appliances in this lecture.There is no TMJ cure in this lecture.So what is the purpose of this lecture?

Simply said: Dynamic EMG ......

NEXT


Simply said: Dynamic EMG is a tool, not a treatment!

1. Muscles help form and stabilize teeth.2. Balanced muscles stabilize the occlusal plane.3. You can evaluate muscle balance for any appliance, any crown placement, or any surgery.4. You can also assess some swallowing problems.5. You can also assess muscle aspects of TMJ/TMD.


And

You can do it while a patient is in the chair.

It takes 3 or 5 minutes.

You have a Report immediately.You can do it again as many times as needed.

PRACTICAL BACKGROUND

“I am afraid of making a fool of myself.”


• What is the biggest problem in communicating with your patient?

• How much time do you have to communicate with your patient?

• What kind of evidence do you present?

InnerSmile Pro ©


Structural evidence is objective.

- X-rays, casts, models, tomograms

Functional evidence is usually ignored, or referred out.

- sEMG, TMJ Bite Muscle Analysis, Etc

InnerSmile Pro ©


STRUCTURAL EVIDENCE:- This is the Outer

Smile

FUNCTIONAL EVIDENCE:- This is the Inner

Smile. InnerSmile Pro ©


* If the Matrix is Neutral, you will see balanced clench and swallow.

‘OUTER SMILES’are static, teeth-based smiles.They may be genuine smiles or superficial smiles or spontaneous or posed smiles.

‘INNER SMILES’are much different. They are really Gugino’s Functional Matrix.

KEY POINTS:

1. FUNCTIONAL ESTHETICS & Inner SmileTo neutralize the functional matrix, enhance esthetics

2. CORRECTIVE ORTHO & Inner Smile To neutralize (train) Breathing/Swallowing

To neutralize (train)Muscle To neutralize (train)Posture

How can you neutralize what you can't evaluate?

KEY POINTS:

3. PREVENTATIVE ORTHO & Inner SmileDynamic sEMG shoud be done on every patient.

A new Dynamic sEMG should be taken for every re-evaluation

Why?The Functional Matrix is also Dynamic.

* However if your patient's inner smile [Functional Matrix] is not within the neutral zone, how do you communicate this to the patient?The purpose of this talk is to show how to use the sEMG scanner to communicate whether the inner smile is in the neutral zone.

You can communicate a good outer smile to a patient.

MUSCLE PATTERNS

◦ So, how do you evaluate this

basic sEMG muscle pattern?

There are 5 elements to the sEMG

muscle pattern :

NEXT…


The five elements in dynamic

muscle evaluation are :1. Resting Muscle Pattern

2. Initial Contraction Pattern

3. Sustained Contraction

Pattern

4. Release Pattern

5. Post-Contraction Pattern

“Muscle Asymmetry is shown by comparing muscle pairs.”


“OK. But is it IMPORTANT?”

Yes, it sets practical functional treatment plans.

But …If you can't communicate it, don't do it.

Ask another question:

“Are asymmetries always the same?”

Humm. Take a look at the next slide.

WHAT ABOUT THIS

PATTERN?

InnerSmile Pro ©


Right Temporalis Muscle

Remains active at rest

Very little amplitude during clench.

Digastric m. also low, until swallow ->


A simple 3 or 5 minute exam provides

objective

information about stability of the jaw in

action.

A simple clench-release test tells you about

soft-tissues:

1. Does a clench favor one side over the other during a

clench?

2. Does a clench show dominance of the anterior

temporales?

3. or do the masseters dominate?

4. Is the clench stable?

“So what. I don't understand!”

That's because no one looked at digastrics in this manner.People who contract the digastric muscle while clenching the

masseters need a full swallowing analysis.

Usually they have an undiagnosed breathing-swallowing problem.

CPS

muscle pairs.

The 7 Minute scan that will

Technical : Microbreaks are related to Muscle Spindle

looping – like an auto-reset on the computer to keep it

clear under load.

Healthy Muscles show ‘microbreaks’ –

Split second gaps in contraction that allow blood flow, and sustained endurance.
