Occlusion Connections — The Center for Gneuromuscular Dentistry & Orthopedic Advancement

The OC Experience · A Gathering of Clinicians of Like-Mind

The Doctors of OC

With growth and development comes change, new ways of thinking and maturity. With maturity comes confidence, with confidence comes a sure future with a greater vision and purpose.

They come from Singapore, Tokyo, Japan, Indonesia, Kolkata, Mumbai, India, Perth, Australia, Vancouver BC, Ottawa, Toronto, Calgary, Canada, Nürnberg Germany, Munich, Moscow, Russia, Spain, Malaysia, Taiwan, Palestine, Israel and from every corner of the United States — general practitioners, specialists, and laboratory technicians who decided that occlusion deserved a deeper answer. Many return year after year, level after level. These are their classes.

“The willingness to learn and share and the courage to champion for true dentisty set the OC doctors apart from the pack. I am proud to be a part of this. Can’t get enough of it.”

“A safe and respectful place where everyone can ask their questions… couldn’t be more accurate or appreciate! To be able to cover the planned material at each course with all the ebbs and flows that a study club atmosphere provides is a tribute…and the environment that they promote and support with all their efforts.”

“I think the beauty of OC is that you have been able to combine the time tested principles of gnathology with advanced neuromuscular thinking in a logical and precise fashion. The courses are outlined in such a fashion as to enable the doctor to grow at their own pace regardless of their background, training, or experience. And best of all, OC is a safe and respectful place to learn where everyone can ask their questions without fear of being judged harshly by their colleagues.”

“After years of bouncing around different schools of thoughts, I finally found a home in OC. Clayton has put together the most detailed and comprehensive collection of both clinical and academic research and real world “wet fingered” dentistry. No theories here, all knowledge gets put into real clinical test and the results have been astounding for my practice.”

“I encourage every dentist who has some or no occlusion background should take Occlusion connection courses. I have taken 8 +2 courses with Dr. Clayton Chan and no doubt it has transformed my dental career and allowed me to practice advanced dentistry with high confidence. I really got hooked and addicted to his teaching at the beginning and it did take me two straight years to complete his 8+2 courses.”

“Finally after 4 years I was “blinded”, learned by myself and bothered my Singapore colleagues a lot about optimized bite, last month I saw myself and learned to take the Chan’s optimized bite from Dr. Chan himself! (thanks Dr. Chan and all OC docs from your warm hello). Lv 1 was really opening my eyes.”

“A wealth of knowledge and information provided beyond past NM educational training. A real “eye opener” learning experience! Dr. Chan offers a unique ability to convey his expertise in a manner that makes learning easy. Nothing was left to chance!! OC has created a “personalized learning experience” beyond any C.E. course I have ever taken before.”

“Just got back from Level 1 and I have to commend Clayton on a wonderful job of blending more advanced material with delivering the NM message all at the same time. I highly recommend the 2 days to all as I know you will return with very practical information that you can apply immediately. It is nice to spend 2 days with someone with as much passion for teaching NM dentistry as Clayton.”

“I was amazed at how much I still learned in your level 1 course. There is no way to “overthink” things when learning from Clayton. He presents things in such a practical and understandable format that you really walk away “getting it”. The class size was perfect for learning and I felt like I had enough individual time with Clayton to ask my own questions about certain cases that I am seeing in my practice.”

Rod Strober, D.D.S.

“You presented many new insights into gneuromuscular dentistry which were never taught before. THE MOST IMPORTANT FOR ME WAS THAT I WAS ABLE TO COME HOME AND TAKE BETTER BITES ON MONDAY MORNING CONSISTENTLY. Those seasoned K7 vets, you won’t be wasting your time, honestly.”

Thomas C. Streko, D.M.D.

Westfield, New Jersey

“There is no substitute for the hard work of taking on cases and just problem solving them one at a time. I know if you continue on this GNM OC journey you will be given enough information to be successful. All you need to do is apply it and “Pay attention to the Details”….. that is it!”
