Claims20
1) A dental implant comprising:
- an internal fluidic chamber extending axially through the implant;
- one or more inner microfluidic channels extending radially from the internal fluidic chamber to one or more outer microfluidic channels;
- one or more outer microfluidic channels, wherein the outer microfluidic channels comprise a helical groove transversing outer threads of the implant;
- an actuator configured within the internal fluidic chamber to pump liquid through the implant in the presence of a magnetic field;
- a flexible magnetic valve configured between the internal fluidic chamber and the one or more inner microfluidic channels, wherein the flexible magnetic valve is opened or closed through application of an axial external magnetic field;
- and
- a stopper structure bonded to the flexible magnetic valve, wherein the stopper structure maintains an opening angle or a closed position of the flexible magnetic valve after the axial external magnetic field has been removed.
