Lightwire Expander: Farrell Bent Wire System (BWS)
Chris Farrell, the developer of the Myobrace system, uses this light wire expander to give the teeth and jaws a boost while wearing the Myobrace. It's gentle, doesn't show at all from the front, and give plenty of room for the tongue to learn to be on the palate. It is my favored appliance to use as an adjunct to Myobrace.
It is made of a .028 inch removable steel wire anchored to two silver bands on the back teeth. I remove it at each visit to change its shape and put it right back. It does it's job in 4-6 months in most cases. It can be used on the upper or lower teeth as needed. Click the picture for more information.
Advanced Lightwire Functional (ALF)
Similar in function to the BWS, the ALF is a one-piece appliance that clips onto the teeth. Although it can be found in the literature as early as 1918 (Rogers), the developer of the most recent version, Darick Nordstrom, designed it to help grow the bones with by tuning into their natural growth rhythms.
The technique is best done in coordination with: 1) a Cranial Osteopath who will make sure the sutures between the skull bones remain open and flexible, and 2) a Myofunctional Therapist who will make sure the muscles of the mouth and face promote good growth.
It is a very gentle technique and can be done at any age, but it is also done slowly and takes time.
Many people like the ALF since it doesn't show from the front. It's a good "invisible" technique.
The Crozat was developed at the same time the earliest fixed appliances (braces) were developed. Although braces became more popular, there is still quite a large following of Crozat practitioners the world over. These appliances are a hybrid of tooth moving and orthopedic. They are gentle and easy to wear for adults who want nothing to show and have lots of patience.
Daytime/Nighttime Appliance (DNA)
Developed by researcher, dentist, and all around ego-maniac, G.David Singh, this removable appliance is purported to tap into the genetic potential the jaw has for proper growth (epigenetics) thus allowing the body to do its best. While it does not accomplish as much as the Biobloc, practitioners that use this appliance are very satisfied with results, especially in adults who cannot use the Biobloc
