Abstract
There is provided in accordance with an exemplary embodiment of the invention a method of osteointegration of an implant into surrounding jaw-bone, the method comprising: applying a magnetic field around an implant, the magnetic field produced around the implant to a jaw-bone depth of up to at least about 7 mm, the magnetic field having a magnetic flux density of about 0.05-0.5 mT at up to at least about 2 mm from a surface of the implant, the magnetic field produced by a coil within the implant. A device adapted for insertion into a jawbone implant and for producing the magnetic field for bone enhancement of surrounding jawbone is also described.
Claims24
An energy saving circuit configured for electro-magnetic orthopedic therapy, said circuit comprising:
- a coil arranged to produce an orthopedic therapeutic electro-magnetic field;
- a capacitor in series with said coil;
- one or more switches in series with said capacitor;
- and
- a controller to:
- control said switches to maintain said capacitor at a first voltage value during a non-pulse phase, wherein no electro-magnetic field is produced,
- control said switches to charge said capacitor to a second voltage value, said second voltage value equal to said first voltage value, said second voltage value having a charge opposite to said first voltage value;
- and
- control said switches to further charge said capacitor from said second voltage value back to said first voltage value, said further charging occurring over a time period of a pulse phase, wherein said charging and said further charging said capacitor comprises passing a current through said coil to produce said electro-magnetic field, said current related to a voltage drop across said coil of about two times said first voltage value.
A method for producing an electro-magnetic orthopedic therapy field comprising:
- providing a coil arranged to produce an orthopedic therapeutic electro-magnetic field and a capacitor in series with said coil, said capacitor configured to store sufficient charge to pass a current through said coil to produce said electro-magnetic field;
- maintaining said capacitor at a first voltage value during a non-pulse phase, wherein no electro-magnetic field is produced,
- charging said capacitor to a second voltage value, said second voltage value having a charge opposite to said first voltage value;
- and
- further charging said capacitor from said second voltage value back to said first voltage value, said further charging occurring over a time period of a pulse phase, wherein said charging and said further charging said capacitor comprises passing a current through said coil to produce said electro-magnetic field.
