Abstract

Methods of treating malocclusion and inducing osteogenesis as well as an apparatus for treating malocclusion are described. The methods and apparatus utilize cyclic forces as compared to static forces to achieve their results.

Claims

1. A method for inducing a predetermined amount of bone remodeling and modeling in a cranium of a mammal in need thereof, by enhancing osteogenesis of cranial sutures, the method comprising:

(a) applying cyclic forces to a cranial region of said mammal in which bone remodeling is desired with a peak magnitude of up to about 10 Newtons and frequencies of up to about 40 Hz in a direction lateral to the sutures for a predetermined period of time; and

(b) repeating said application a plurality of times until a predetermined amount of bone remodeling and modeling in the cranium is obtained from the osteogenesis.

2. The method according to claim 1 wherein said cyclic forces are repeatedly applied a plurality of times each day.

3. The method according to claim 2 wherein said cyclic forces are repeatedly applied over a period of days or months.

4. The method according to claim 1 wherein said peak magnitude is about 5 Newtons.

5. A method for inducing a predetermined amount of osteogenesis in the cranium of a mammal in need thereof, the method comprising:

(a) applying cyclic forces to a cranial region of said mammal in which osteogenesis is desired with a peak magnitude of about 10 Newtons and frequencies of about 0.1 to about 40 Hz for a predetermined period of time; and

(b) repeating said application a plurality of times daily until a predetermined amount of osteogenesis is obtained.

6. The method according to claim 5 wherein said cyclic forces are repeatedly applied over a period of days or months.

7. The method according to claim 5 wherein said cyclic forces are applied to the cranial sutures of said mammal.

8. The method according to claim 5 wherein said cyclic forces are applied at a frequency of about 0.1 to about 40 Hz.
