  • nozzle outlets have an external diameter of 2 mm to 4 mm.
  • Nozzle outlets can also have an exterior shape that is the complement of the interior surface of the implant. Using a nozzle with a complementary shape will minimize the gap between the nozzle and the implant. This allows cleaning to be performed efficiently, with minimal cleaning fluid needed.

As shown in FIG. 7, the movement of the implant away from the nozzle, as a result of the pressure of the fluid ejected from the nozzle, creates an opening between the nozzle and the implant that allows the fluid to exit the interior of the implant. As the fluid exits the interior of the implant, debris and oil is carried away by the fluid.

Once the implants are placed on the nozzles, the cover plate is positioned over the implants and lowered onto the spacers. The cover is carefully positioned over the implants so that the implant extension from each of the implants enters the openings in the cover (See FIG. 4). Once properly positioned, the cover is fastened to the implant support using the fastening system. The implant support is then turned over and the procedure is repeated on the opposing side. The fully loaded implant support is shown in FIG 5.

As the fluid exits the interior of the implant, the fluid can create turbulence in the fluid surrounding the implants, providing cleaning to the outer surface of the implant.
