AIRWAY-kening® Orthodontic/Orthopedic Development: A Correlation of Facial Balance, TMD, and Airway for All Ages

  • William M. Hang


The lack of forward growth of the lower face in humans relative to our ancestors has major health implications. Aside from having malocclusions, people in modern industrialized societies are dealing with reduced airways resulting in breathing problems, obstructive sleep apnea (OSA) being a far too frequent occurrence. OSA is associated with virtually all chronic diseases afflicting modern man. With 40% of people over age 40 snoring and snoring alone (without OSA) being correlated to plaque formation in the carotid arteries, we are dealing with an epidemic few know about.

Many orthodontic treatment plans are retractive. Recessed faces are being even further recessed with airways potentially reduced even further. The time has come to establish a new paradigm for airway health. It must be centered on treatment to optimize forward growth of the face which can optimize the airway. We must enter an era of non-retractive orthodontics which means eliminating much of what has been done in the past and embracing new approaches which are diametrically opposed to the old paradigm.

Treatment approaches for all ages, from young children in the primary dentition to teenagers at the traditional orthodontic age, to adults who have had retractive orthodontics and suffer from OSA, are outlined with specific examples given to illustrate the efficacy of this new approach.
