Abstract
A dental implant having two distinct regions, a coronal region and a bone fixation region. The coronal region has a smooth transgingival section and an interface for connecting to a dental component. The bone fixation region has an elongated cylindrical shape and is formed as a porous structure that extends completely through the bone fixation region.
Claims16
A dental implant, comprising:
- a coronal body formed of solid metal, having a proximal end, having a distal end, and having a cylindrical shape;
- and
- an elongated cylindrical porous body that forms a porous metal structure having a proximal end that connects to the distal end of the coronal body at an interface, wherein the porous metal structure extends throughout the porous body and through a center of the porous body in a cross-sectional view of the porous body such that the porous body is a completely porous structure in the cross-sectional view, the distal end of the coronal body has a circular shape, the proximal end of the porous body has a circular shape, and the solid metal of the circular shape of the coronal body interfaces with the completely porous structure of the circular shape of the porous body at the interface.
A dental implant, comprising:
- a coronal body having a distal end and a proximal end, being formed of solid metal, and having a cylindrical shape;
- and
- an elongated cylindrical porous body having a proximal end connected to the distal end of the coronal body at an interface and having an interconnected porous structure, wherein the interconnected porous structure is formed of metal and fills central portions of the porous body by extending through a center of the porous body in a cross-sectional view of the porous body, the distal end of the coronal body has a circular shape, the proximal end of the porous body has a circular shape, and at the interface the circular shape of the coronal body is filled with the solid metal that interfaces with the circular shape of the porous body that is filled with the interconnected porous structure.
