Apparatus is provided that includes a dental implant having a distal implant portion that extends from a distal implant end along up to 50% of a longitudinal length of the implant, the implant shaped so as to define a lumen through the implant, which lumen has at least one distal opening through a distal external surface of the distal implant portion. The apparatus further includes a swivel joint having first and second joint portions defining first and second joint ports, respectively, the swivel joint arranged so as to define a fluid path from the second joint port to the first joint port via the second and first joint portions, which are arranged to be rotatable with respect to one another such that the fluid path is preserved during rotation. The fluid path through the swivel joint is in fluid communication with the lumen via the first joint port.
