A concrete tensioning band is disposed on a surface of unhardened concrete and tensioned by being attached to a clamp disposed on the base, and then displacing the clamp by a drive mechanism disposed on the clamp. Each electrode comprises a structure with a network of through-passages, surrounded by a solid frame. Short primer extension periods results in a recombined template having paired 5 and 3 ends that can then be amplified. The damming composition is dissolved by increasing the water pressure after completion and inspection of the plumbing work. A desired overall implant inclination angle may be achieved by matching various implant stems with various reverse inserts, thus permitting a resection surface to be matched with an implant stem selection while also permitting a desired overall implant inclination angle to be achieved through the selection of an appropriate insert.
