Abstract

An endosteal implant, and the method for performing the implantation thereof, which promotes rapid and complete securing of the inplant to bone tissue. Soft tissure at a bone site is incised and a bore is drilled in the exposed bone. An implant housing is inserted in the bore. The implant housing is constructed so as to be able to receive a selectively removable electrical power source therewithin. When the power source is received within the housing located in the bore in the bone, and the soft tissue is sealed over the implant housing site, the power source produces an electrical current travelling through the tissue and the bone surrounding the site. Such current promotes cellular adhesion activity thereby substantially reducing the time for securing the implant housing to the bone. Subsequently, the electrical power source may be removed and replaced with a suitable abutment for affixing a desired prosthesis to the implant housing. Alternatively, the power source may be permanently left within the implant housing.

Claims

1. An endosteal implant capable of substantially reducing the time for securing said implant to the bone, said implant comprising:

an implant housing adapted to be placed at an endosteal site and covered with soft tissue, said housing defining a bore extending from one end of said housing interiorly thereof;

a removable electrical power source selectively insertable into said bore of said housing and retainable therein to establish an electrical current flow through soft tissue and bone completely surrounding said housing when implanted at a desired endosteal site, whereby such current flow promotes cellular adhesion activity thereby substantially reducing the time for securing said implant to the bone, and

an abutment selectively insertable in said bore of said housing for affixing a desired prosthesis to said housing when said power source is removed therefrom.

3. The invention of claim 1 wherein said electrical power source is a dry primary battery.

2. The invention of claim wherein said housing has an external configuration which makes said housing self-tapping.

4. A method for performing endosteal implant with a substantially reduced time for securing the implant to the bone, said method comprising the steps of:

incising soft tissue to expose bone over the site where the implant is to be located;

drilling a bore in the exposed bone;

inserting in such bore, an implant housing having a removable power source;

sealing the soft tissue over the implant housing using the electrical power source to produce an electrical current flow traveling through the soft tissue and bone surrounding the implant housing site to promote cellular adhesion activity thereby substantially reducing the time for securing the implant housing to the bone;

incising the soft tissue over the site of the implant housing;

removing the electrical power source from the housing; and

replacing the power source with a suitable abutment for affixing a desired prosthesis to said implant housing.
