Presented below are sequencial video clips of an entire all-day CE course presented
by Dr. Boyd (with Barry Glassman, DMD, in San Diego in January 2008).

This entire course content is presented as a courtesy to both practitioners and patients.
Dentists who would like to obtain AGD approved CE credit (up to 5 CE credits potential) for this on-line
course can go to CEDentistry.com and pay an administration fee per unit for the number of units desired.

The TMDaVinci Code

"From tooth wear to migraine,
taming the forces that
threaten everyday dentistry"

The linked titles below are 8-10 minute video clips of Dr. Boyd describing concepts from the
corresponding PowerPoint Video show (each linked segment will open in a new browser window).

The INTRODUCTION plus PURPOSEFUL FUNCTION (all six sections) qualify for one unit of CE.
INSIGHTS ON PARAFUNCTION (sections 7-16) qualifies for two units of CE.
PRINCIPLES OF PARAFUNCTIONAL CONTROL (parts 1-8) qualifies for two units of CE.

Introduction: (click here to view the PowerPoint Video corresponding subject titles)

Introduction: Historical perspective overview - Active Elevation - A three-legged stool? - Definition of Dentistry - TMDaVinci Code of Occlusion

Purposeful Function: (click here to view the PowerPoint Video corresponding subject titles)

Section 1: DIAGNOSIS definition - Function obligates Form - Trigeminal Sensory Modulation

Section 2: Trigeminal motor and sensory root - Electric motors - Muscle fiber innervation - What EMG represents - Normal incising with minimal resistance

Section 3: Normal incising with minimal resistance - Incising upon considerable resistance - Crushing considerable resistance - Trigeminal motor circuitry completion - Occluding circuitry completion - Motor activity = Masticatory activity - Fourth factor of motor activity

Section 4: Masticatory innervation, CR INTRO - Basics of mand. position & movement FROM CR

Section 5: Clenching: Purposeful Necessity? - Function dictates Form provides Function (what CANINES are really for) - Temporalis vs. Masseter - Muscle responsibility of "working movement"

Section 6: Interference to working closure - Deprogramming to reveal interferences - Extremes of purposeful function

Insights on Parafunction: (click here to view the corresponding PowerPoint Video subject titles)

Section 7: Functional mandibular positions - Lateral pterygoid maximum intensity - Resistance to Opening - Dentistry stipulates closed

Section 8: Final closing vs. Initial Re-opening - Encountering resistance to opening - Propulsion of twin entine boats

Section 9: How joints are strained - Mandibular propulsion motors - Collision patterns of motor hyperactivity

Section 10: Insight on "cervical parafunction" - PARAFUNCTION diagnosis and description

Section 11: Parafunction description (it's all relative) - Catagories of Parafunctional Occluding Schemes - The continuum of parafunction

Section 12: Catagories of Parafunctional Occluding Schemes - Traditional Splint Therapy Failure - Sleep Cycles

Section 13: Primary Clenching - Occlusal Therapy Treats Parafunction (Dawson)

Section 14: Where a traditional splint fails - Goals for splint therapy - Deprogrammer enhancement - Michael Melkers DVD - NON-distalization due to incisal contact - Non-realistic observation of articulators

Section 15: Error in excessive VDO of splint therapy - Error of excessive VDO in extreme protrusion - Addressing parafunctional occluding schemes with an Enhanced Deprogrammer - Treating pathologic condyle

Section 16: Mini Implant Screws to close VDO (Temporary Anchoring Devices, TADs) (start) - TMDaVinci Code Breaking (2:02)

Principles of Parafunctional Control -
(click here to view the corresponding PowerPoint Video subject titles)

Part 1 Intro - Principles of Parafunctional Control - Three possible therapeutic outcomes

Part 2 Limits of Purposeful Protrusion - Purposeless Protusive "Function" - Therepeutic goals in protrusion - Excessive VDO in protrusion - Extending DE for protrusive clencher

Part 3 How and when to increase VDO of the DE - Typical reduction of DE in protrusive - Improper delivery of a maxillary device - The tangent surface of the IG device

Part 4 Avioding upper canine on lower DE - Posterior contact in excursive - Maintain minimal VDO in protrusive - Deep bite with a "Z" step device - Excessive VDO with "standard" device

Part 5 Revealing a click - Protrusion increases as resistance decreases - Excursion increases as resistance decreases - Severe excursion with posterior contact - Adapting for excessive protrusion

Part 6 DE design for severe class II - DE design for class III - Group parafunction - Bilateral posterior excursive contacts - Clinical: Multiple tx failures

Part 7 Opposing Slider - Anterior deprogrammer / Daytime device - Revealing posterior interference - AOB: Comparing before/after models - Dynamics of a developed AOB (dentist's goals vs. patient's goals)

Part 8 Vacuum-formed devices - NTI over full-mouth brackets
