A method of treating an individual to increase the individual’s bone mineral density is disclosed. The locking base on each end of the carrier having a shoulder to secure the secondary lock, with the locking base for each secondary lock being reduced in length due to the presence of the locking shoulders. The switch element is electrically contacted to a test potential source. The working channel has a segment adjacent to the distal end that is narrowed so as to cause the fluid to exit the working channel into the target region in a diverging cone. A customized jig may be designed and fabricated for inspecting a dental prosthesis or components thereof throughout the manufacturing process. The method and system further include a graphical user interface and returns a statistical confidence of the predicted savings or loss.
