Abstract
A dental implant for installation into a mouth is disclosed. The implant includes a one piece implant body to which is attached an abutment portion for anchoring a denture or tooth replacement. The implant body includes a coronal portion having a keyway. The abutment portion includes a key which mates with the keyway to form a non-rotational joint. In one aspect of invention, the abutment portion is cemented into the keyway. In another aspect of the invention, the key is tapped in to the keyway to form a cold weld. There is also shown a method of installing a dental implant which includes press fitting the implant body into a preformed cylindrical bore at the implant site. The abstract is made retrievable without disturbing the bone implant interface.
Claims8
An implant for anchoring a prosthetic device in bone said implant comprising:
- a) a one piece body having a cylindrical intra osseous portion and a transgingival portion, said cylindrical intra osseous portion including a porous coated root portion and a smooth-walled emergent portion, said transgingival portion including a keyway;
- and
- b) a cementable abutment portion for insertion into said keyway, said cementable abutment portion including a key at one end for insertion into said keyway, said key and said keyway being sized and shaped to provide cement space therebetween, said cementable abutment portion also including a head at the other end for retention of said prosthetic device, and a shoulder, on said head, said shoulder being sized and shaped to permit said cementable abutment portion to be pried off said body when cemented thereto.
A method of inserting a dental implant comprising:
- incising through a gingival layer;
- drilling a pilot hole with a first drill bit at an appropriate location into a bone located below said gingival layer,
- drilling a cylindrical recess, about said pilot hole, into the bone with a second drill bit,
- gently tapping said implant in frictional engagement with said bone wherein said step of tapping includes seating said implant against a bottom of said recess;
- allowing said bone to grow into a root portion of said implant, and
- cementing a retrievable abutment to said implant.
