A modular dental implant including a body portion, a sleeve, and an end cap. The sleeve may be formed of porous material, such as a porous metal material to promote bone ingrowth. The sleeve is positionable around a core of the body portion and the end cap is attached to the core of the body portion such that the sleeve is positioned between the head of the body portion and the end cap. The sleeve includes one or more anti-rotation features formed in the upper surface and/or lower surface of the sleeve configured to interact with one or more anti-rotation features formed in the lower surface of the head of the body portion and/or the upper surface of the end cap which prevent rotation of the sleeve relative to the core of the body portion.

Implant with porous sleeve including anti-rotation features

A dental implant can include a shaft defining a longitudinal axis and having an apical end, a coronal end, and an exterior surface. A portion of the exterior surface can include a porous material. The dental implant can include at least one thread, including a non-porous material, having an interior surface and a bone-engaging surface. The interior surface can engage and wind around the exterior surface of the shaft and the bone-engaging surface can extend outwardly from the exterior surface of the shaft. The shaft can include one or more channels configured to communicate a flowable material, stored within the shaft, to the exterior surface. Each channel can include an opening at the exterior surface to release the flowable material. At least one channel can extend between a cavity of the shaft and the exterior surface and can optionally be angled toward the apical end.
