The ALF Appliance is an Orthopedic Growth Appliance that has a low profile in the mouth. They are utilized for Maxillary expansion, Treatment of TMJ Disorders, Finishing Physiologic Cases, Treating Snoring and Sleep Apnea and other issues.
I used Crozat Appliances for years and the ALF or Advances Lightwire Functional Appliance is very similar. It is a deceptively simple appliance, by appearance only. It is crucial that adjustments are precise as it can produce unwanted changes very easily.
My preference is to utilize Epigenetic Orthodontics with the dnA Appliance to three dimensionally grow the maxilla orthopedically and to grow airway Pneumopedically.
The mRNA version of the DNA appliance can not only treat sleep apnea and snoring (sleep disordered breathing) but has been shown in clinical cases to be able to cure sleep apnea by growing a larger airway. Large prospective studies ar not yet complete.
The Appliances can treat TMJ disorders by correcting an underdeveloped maxilla that forces the mandible posteriorly.
