Abstract

Embodiments of the present disclosure are directed to devices and methods for stimulating cell proliferation. In one implementation, a method for increasing cell proliferation is provided. The method includes providing a vibrational dental device configured to vibrate at a frequency higher than about 60 Hz. The method also includes mechanically stimulating, using the vibrational dental device, cells for a treatment period of less than about 10 to 20 minutes daily. The method may further include generating a peak acceleration magnitude in the horizontal direction substantially greater than that in the vertical direction. The number of the cells at the end of the period of time is increased. The cells may include at least one of human osteoblasts and fibroblasts.

Claims

1. A method for increasing periodontal cell proliferation, the method comprising:

providing a vibrational dental device configured to vibrate at a frequency higher than about 60 Hz, wherein a peak acceleration magnitude generated by the vibrational dental device in the horizontal direction is substantially greater than that in the vertical direction;

mechanically stimulating, using the vibrational dental device, periodontal cells, including at least one of human osteoblasts and fibroblasts, for a treatment period of less than about 10 minutes daily; and

wherein the number of the periodontal cells at the end of the period of time is increased.

2. The method of claim 1, wherein the vibrational dental device is configured to vibrate at a total acceleration magnitude ranging between about 0.001 G and about 3 G.

3. The method of claim 1, wherein the peak acceleration magnitude produced by the vibrational dental device in the horizontal direction is about five times greater than that in the vertical direction.

4. The method of claim 1, further comprising mechanically stimulating the cells at a frequency between about 60 Hz and about 300 Hz.

5. The method of claim 1, further comprising mechanically stimulating the cells at a g-force between about 0.001 G and about 3 G.

6. The method of claim 1, wherein the vibrational dental device comprises a mouthpiece and a motor connected to and configured to vibrate the mouthpiece.

7. The method of claim 5, further comprising providing the mouthpiece between the occlusal surfaces of a user'"'"'s teeth to be clamped by the user'"'"'s teeth.

8. The method of claim 6, further comprising applying an axial vibratory force on the occlusal surfaces by the vibrational dental device.

9. The method of claim 1, further comprising detecting vibration characteristics of the mouthpiece produced by the vibrational dental device.

10. The method of claim 1, further comprising adjusting the frequency and/or g-force of the vibration of the vibrational dental device.

11. The method of claim 1, wherein the period of time ranges from a couple of days to a few months.

12. The method of claim 10, wherein the period of time ranges from a couple of days to a few days.

13. The method of claim 10, wherein the period of time ranges from a few days to couple of weeks.
