Porous metal dental implant
View Patent ↗A porous metal augment is sized for use in mandibular or maxillar bone. The porous metal material of the augment facilitates and promotes ingrowth of the surrounding bone into the porous metal structure, thereby rebuilding a suitable foundation for affixation of dental implants. A non-porous core or insert can be embedded within the porous metal body of the augment, and can be made of a material suitable for firm threaded fixation of dental implants thereto. For example, the metal core can be formed of a titanium structure that has sufficient strength and resiliency to form a firm and long lasting threaded connection with a threaded stem of a dental implant.
1. A dental augment system, comprising;
a porous metal augment sized to be received in a cavity formed in at least one of a mandible or maxilla, the porous metal augment having a first bore defining a first bore axis and a second bore defining a second bore axis;
a core having a first threaded bore, the core receivable within the first bore along the first bore axis of the porous metal augment;
an adaptor having a second threaded bore and a threaded exterior surface, wherein the adaptor is insertable into the second bore formed along the second bore axis of the porous metal augment, and the adaptor being threadably engaged into the first threaded bore of the core; and
a dental implant configured to be received in the second threaded bore of the adaptor such that at least a portion of the dental implant is positioned within the porous metal augment.
2. The dental augment system of claim 1 , wherein the core and the adapter are formed from at least one of titanium and cobalt-chrome-molybdenum.
3. The dental augment system of claim 1 , wherein the second threaded bore of the adaptor is configured to be threadably coupled with a threaded implant portion of the dental implant.
4. The dental augment system of claim 1 , wherein the second bore of the porous metal augment extends from a superior surface of the porous metal augment into the first bore of the porous metal augment.
5. The dental augment system of claim 1 , wherein the first bore of the porous metal augment is in communication with the second bore of the porous metal augment.
6. The dental augment system of claim 1 , wherein the second bore axis is substantially perpendicular to the first bore axis.
7. The dental augment system of claim 1 , wherein the second bore axis is oblique to the first bore axis.
8. A dental augment system, comprising;
a porous metal augment sized and shaped for implantation into a mandible or maxilla, the porous metal augment having a first bore defining a first bore axis and a second bore defining a second bore axis;
a core receivable within the first bore along the first bore axis of the porous metal augment and comprising a first threaded bore;
an adaptor defining a second threaded bore and having a threaded exterior surface, the adaptor insertable into the second bore formed along the second bore axis of the porous metal augment and is configured to be affixable to the core, and wherein the adaptor is threadably engaged into the first threaded bore of the core; and
a dental implant having a threaded implant portion configured to be threadably coupled with the second threaded bore of the adaptor, such that at least a portion of the threaded implant portion is positioned within the pours metal augment.
9. The dental augment system of claim 8 , wherein the core and the adapter are formed from at least one of titanium and cobalt-chrome-molybdenum.
