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.
Claims26
A system for bone enhancement comprising:
- a device adapted for insertion into a bone implant, said device including
- a housing including an implantable portion sized and shaped for implantation into the bone,
- a first transmitter at least partially inserted into said implantable portion of said housing, said first transmitter arranged to transmit at least a bone enhancing magnetic field for said bone enhancement and
- a magnetic switch coupled to activate said first transmitter to an active state that continues for a treatment period, said magnetic switch activated by an external magnetic field and said first transmitter remaining in said active state after removal from said external magnetic field;
- and
- a cradle having a recess sized and shaped to fit said device, said cradle including
- second transmitter arranged to produce said external magnetic field.
A system for bone enhancement comprising
- a device adapted for insertion into a bone implant, said device comprising:
- a housing including an implantable portion sized and shaped for implantation into the bone
- a first transmitter at least partially inserted into said implantable portion of said housing, said first transmitter arranged to transmit at least a bone enhancing magnetic field for said bone enhancement;
- a magnetic switch coupled to activate said first transmitter to an active state that continues for a treatment period, said magnetic switch activated by an external magnetic field and said first transmitter remaining in said active state after removal from said external magnetic field and
- a second transmitter arranged to produce said external magnetic field;
- said second transmitter including a cradle shaped and sized to stand stably on a flat structure and for mechanically engaging said device to support said device while activating the device with said external magnetic field outside of said bone implant.
A system for bone enhancement comprising:
- a device adapted for insertion into a bone implant, said device including
- a housing including an implantable portion sized and shaped for implantation into the bone,
- a first transmitter at least partially inserted into said implantable portion of said housing, said first transmitter arranged to transmit at least a bone enhancing magnetic field for said bone enhancement and
- a magnetic switch coupled to activate said first transmitter to an active state that continues for a treatment period, said magnetic switch activated by an external magnetic field and said first transmitter remaining in said active state after removal from said external magnetic field;
- a second transmitter arranged to produce said external magnetic field;
- and
- a testing circuit including a coil for testing the power level generated by said implantable device by measuring a current induced by the bone enhancing magnetic field on the coil.
