CLAIMS
What is claimed is:
1. A facial alignment system comprising: a first mask portion and a rear portion, wherein the rear portion includes a tightening mechanism mounted thereon, wherein the tightening mechanism includes first and second tightening members that extend from the rear portion to the mask portion, and wherein the first and second tightening members are configured to exert a tightening force on the first mask portion.
2. The facial alignment system of claim 1 wherein the first and second tightening members are removably attached to the first mask portion.
3. The facial alignment system of claim 2 further comprising a second mask portion, wherein the first and second tightening members are configured to be removably attached to the second mask portion.
4. The facial alignment system of claim 1 wherein the first mask portion includes first and second connection members, wherein the first tightening member is connected to the first connection member and the second tightening member is connected to the second connection member.
5. The facial alignment system of claim 4 wherein the tightening mechanism includes a rotary dial, wherein when the rotary dial is rotated the first and second tightening members are pulled.
6. The facial alignment system of claim 1 wherein the first mask portion includes at least a first pressure zone.
7. The facial alignment system of claim 6 wherein the first mask portion includes a nose portion, wherein the first pressure zone is located in the nose portion, and wherein the first mask portion includes a second pressure zone that is not located in the nose portion.
8. The facial alignment system of claim 1 further comprising a pressure measurement system.
9. The facial alignment system of claim 8 wherein the pressure measurement system includes at least one measurement device secured to an inner surface of at least one of the first mask portion and the rear portion.
10. The facial alignment system of claim 9 wherein the at least one measurement device is positioned in a pressure zone on the first mask portion.
11. A method comprising the steps of: obtaining a mask assembly that includes a first mask portion and a rear portion, wherein the rear portion includes a tightening mechanism mounted thereon, wherein the tightening mechanism includes first and second tightening members that extend from the rear portion to the mask portion, and activating the tightening mechanism such that the first and second tightening members exert a tightening force on the first mask portion.
12. The method of claim 1 1 wherein the tightening mechanism includes a rotary dial, and wherein the method includes rotating the dial to pull the first and second tightening members.
13. The method of claim 12 wherein the first mask portion includes first and second connection portions, wherein the first tightening member is removably connected to the first connection portion, and wherein the second tightening member is removably connected to the second connection portion, wherein the method further includes disconnecting the first tightening member from the first connection portion, disconnecting the second tightening member from the second connection portion, obtaining a second mask portion that includes a third and fourth connection portions, connecting the first tightening member to the third connection portion, and connecting the second tightening member to the fourth connection portion.
14. A method comprising the steps of: modeling a patient's head to provide a first model, making a first change to a first feature on the first model to provide a second model, and creating a first mask portion using the second model, wherein the first mask portion includes a first pressure zone in a first state.
15. The method of claim 14 further comprising the steps of: making a second change to the first feature on the second model to provide a third model, and creating a second mask portion using the third model, wherein the second mask portion includes the first pressure zone in a second state.
16. The method of claim 15 wherein the step of modeling the patient's head includes the steps of taking a mold of the patient's head and creating the first model using the mold.
17. The method of claim 15 wherein the step of modeling the patient's head includes the step of scanning or measuring the patient's head and providing the first model using computer software.
