Learn About Orthodontics and Obstructive Sleep Apnea in Las Vegas March 2019

We are at an exciting time in dentistry.  The problems related to OSA (Obstructive Sleep Apnea) are becoming more well known and better understood.  
I find it fascinating that as knowledge of any subject increases, we often find out that treatments that were considered “scientific breakthroughs” and “state of the art” can sometimes be realized to create new problems or actually make some situations worse.  During the late 1800s morphine addiction was a serious problem and some well respected scientific minds favored treated those addicted to morphine with cocaine.  Obviously this didn’t work out too well, but it was a popular idea for a few years.  Medical history is full of examples like this.
There have also been some similar situations in orthodontics over the years.  Even into the early 80s, it was very common to do what is referred to as “4 bicuspid extraction”.  This was a treatment where, to decrease crowding, 4 permanent teeth (usually first bicuspids) were extracted to create room and then the anterior teeth were moved backward to fill the space.  This made straightening the teeth pretty easy, but at the time no one seemed to consider the option of keeping all the teeth moving the anterior teeth forward to increase arch length.
The other option was to use “headgear” which is an extra oral appliance that attached to the molars and had an elastic strap that went behind the patient’s neck.  This moved the molars in a posterior direction, creating space in front of them.
What we have learned since then, is that all of this “distalization” actually caused the airway to become more constricted.  When you think about it logically, it makes sense.  You have a finite space in the patient and as you move things backward, the tube that is the airway becomes pushed back and compresses against the spine.  This causes the airway to become more narrow which decreases the volume of air that can pass through it.  Think of this in terms of breathing through a drinking straw.  A straw with a large diameter is easy to breath through, but a very narrow straw makes it very difficult.
To the rescue comes Dr. William Hang.  Here is his bio:

A traditionally trained orthodontist, early in his career Dr Hang saw serious limitations in esthetics and function with the orthodontics he had been taught. Having rejected retraction - in all of its obvious and not so obvious forms - he learned and developed innovative techniques to protect and enhance the airway while enhancing esthetics and function.

Patients from more than 25 states and several foreign countries have come to Dr. Hang for non-retractive orthodontics &/or resolution of their E.R.R.S.™ (Extraction Retraction Regret Syndrome™). In his presentation Dr. Hang will outline these nonretractive techniques as well as give a step-by-step protocol to reopen extraction spaces which often eliminates symptoms such as TMJ pain, facial pain, sunken lips, and SDB/OSA.


Dr. Hang has spoken on orthodontics, facial esthetics and airway locally, nationally, and internationally. He was awarded the AAPMD Lifetime Achievement Award in 2016 for his contribution to the field of airway orthodontics.

Dr. Hang is presenting a seminar on methods and treatment that can provide great aesthetic results while also protecting or opening the airway.  

The seminar is being held at the Aria Hotel in Las Vegas on march 22-23, 2019.

  1. There is a strong need to advertise orthodontic sleep apnea management. C-pap Devices should be available in custom sizes on digital markets like walmart, amazon etc
