Endosseous dental implants tapered over at least part of their length, include two separate portions, a shorter proximal region with half the distance and half the depth between adjacent peaks of multiple lead threads as the longer distal region which has half the number of multiple lead threads as in the proximal region. The permeating is preferably realized by bubbling the gaseous mixture preferably obtained from an inert gas generator through the ballast water over the course of 2+ days while the ballast water is continually maintained a pressure less than atmosphere, preferably \u22122 p. The positioning system also receives differential corrections relative to its pseudo position using packet radio. A sub-cavity is formed within the FP laser cavity. A new financial institution account is then established with a financial institution selected from a list of possible financial institution candidates.
