IMF is also used to aid weight loss; various studies from the 1970s and early 1980s used ivy loops and cap splints to wire the jaws together to enforce a liquid diet until such time as sufficient weight loss had been achieved; this was typically around nine months but in one study could be as long as

There are other methods for wiring teeth together. Ivy loops are a method by which wires are passed between the teeth and gums and then fastened with a loop at the front, and wires are then secured to these loops. Cap splints are metal splints which cover the entire surface of the teeth. Fixation can

OJW does not keep the upper and lower teeth in contact. The sole purpose of the wiring is to limit the extent to which the jaws may open. In the resting position, the teeth are parted 2–4 millimeters, with the lips lightly touching. (The ivy loop method used in the study in
