The A.L.F. or the RN Sagittal |
The A.L.F. and RN Sagittal Applainces have become |
hugely popular with doctors and patients, they are very light, comfortable, easy to adjust and work very quickly to give a superior result compared to some of the older, more common appliances. Because there is no acrylic in the vault of the palate, they allow the tongue to rest in it’s correct position.
The Omega loops in these appliances should be viewed as similar in their role to expansion screws. When you activate a loop, imagine what effect opening an expansion screw in that position would have on the appliance. In their simplistic forms, these appliances can be compared to a 3D Schwarz.
It can be confusing at times to know weather to issue an A.L.F. or an RN Sagittal, so we’ve come up with a quick checklist to help you make an informed decision.
If you need to add one or more of the following,
you need an RN Sagittal;
Posterior Occlusal Coverage
Anterior Bite Ramp
Tongue Wires
Spinner
Individual molar distalization
Reverse Pull Headgear
An A.L.F. appliance has the added ability to be worn in conjunction with fixed brackets, cutting treatment time considerably. The A.L.F. can also be made removable (with crozat cribs) or fixed (slotting into lingual sheaths on bands).
A.L.F. Appliances can be made semi fixed by insertion into lingual sheaths on Molar Bands.
