Abstract
Stimulation of bone growth to facilitate healing of a dental implant utilizing a interiorly threaded dental screw of nonconductive material in conjunction with a healing cap abutment whereby electrical stimulation facilitates healing of the surgical site. The device is powered by a battery for the purpose of creating an electrical-magnetic field to promote bone healing and bone formation. The electric magnetic field is directed to the bone around the device through a battery of a rechargeable type. A constant current is generated in a preferred range of about 5 μA to about 20 μA to stimulate bone healing and bone formation.
Claims24
An osteogenesis device for providing electrical stimulation in bone comprising:
- a dental screw implant member constructed of a nonconductive material defining a longitudinal through going lumen, a hermetically sealed bone growth stimulator device removably mounted to said implant member, said device comprising a casing and stem member mounted to said casing and extending away from said casing, a battery mounted in said casing and circuit means connecting said battery to a lead wire, said lead wire electrically connected to said stem member.
An electrical dental screw implant comprising:
- an implant screw with a head and threaded shank of nonconductive material, said shank being formed with external screw threads and defining an internal bore running the length of the shank, a hermetically sealed bone growth stimulator removably mounted to said implant screw, said stimulator further comprising a housing at a proximal end, a rechargeable battery mounted in said housing, electrical communication means connecting said battery to a lead wire extending distally from said battery and engaging stems means, said stem means being mounted to said housing and extending distally there from, said stem means being adapted to be mounted to said implant screw head and extending outside the distal tip of said implant screw forming a cathode.
An electrical dental screw implant comprising:
- an implant screw with a head and threaded shank of nonconductive material, said shank being formed with external screw threads and defining an internal bore running the length of the shank, a hermetically sealed bone growth stimulator removably mounted to said implant screw, said stimulator further including a housing and rechargeable battery therein at a proximal end, electrical communication means connecting said battery to a lead wire extending distally from said battery, stem means mounted to said housing and extending distally there from, said stem means being adapted to be mounted to said implant screw head, said stem means extending outside the distal tip of said implant screw forming a cathode so that a constant current in a range of about 5 μA to about 20 μA is generated around said stem means when the implant screw and stimulator are implanted in the bone of a patient, and prosthesis adapted to be mounted to said implant screw.
