Welcome to
The Concept of Complete Dentistry Series
he or she can execute the services needed with a very high level of predictable success
and will have a foundation without equal for elevating his or The information in this seminar is foundational for every sequential step toward achieving Master level dentistry... but don't miss the point that understanding occlusion, and how all the components of the masticatory system are interrelated ... is the key to predictable dentistry, regardless of your current practice or type ofspecialty.

“high level of predictable success”

The Ten Factors It is impossible to fully understand occlusion if anyone of the ten critical factors is missing from one's comprehension. The problem for too many dentist is that those who lack a total understanding ofall ten factors typically don't know what they don't know so they never fully realize how predictable dentistry can be. We love to teach this seminar because it is so much fun to see the lights turn on when one learns what he or she has been missing. All of a sudden occlusion starts to make sense. And the nicest part of this is that when itstarts to make senseJ you’ll see it isn t as complicated as youve been told. We are dedicated to helping you really understand occlusion so clearly that it will become life changing. Learn these ten factors and you'll see why We are so sure of their importance in your practice.

FUNCTIONAL OCCLUSION – FROM TMJ TO SMILE DESIGN
Helping Patients to Understand Treatment Needs cuts, are almost fool proof in helping patients to make right decisions
honest approach to patient education, but their use is dependent on the dentist’s understanding of all the factors of occlusion and a goal of long term maintainable health for all the structures in the masticatory a framework for further explanation of cause and effect diagnosis and treatment planning for complete dentistry. One additional mindset is also important. In the entire process of examining and treatment planning, the dentist should act in every respect as an advocate of the
call it the implications mindset 1. Help the patient see and understand every problem. 2. Help the patient understand the implications of not treating each problem in a timely manner. 3. Classify the implications: a. Immediate now. Delay will result in more extensive treatment with possibility of a less satisfactory result. b. Deferable...Treatment will be needed but could be delayed observation at recall appointments. c. Optional...Usually relates to esthetics treatment that would be “nice to have” but is not necessary to keep the teeth healthy. 4. Explain how each problem can be solved. To guide the dentist in all treatment recommendations, I have found that the WIDIOM rule is always a dependable guide. Ask the question:
