Bars of the instrument are expanded and placed on the alveolar process of the jaw so that bushings 6 and 10 precisely match the positions of the 2 distalmost implants. The optimal angle of the implants is selected by changing the angle of inclination of bushings 6 and 10 in labiolingual and mesiodistal directions. Figure 3. First clinical osteotomy placed for implant insertion is completed with a 2-mm diameter pilot drill placed in bushing 10. Figure 4. Supporting axis 1 is placed rigidly in the prepared 2-mm osteotomy that had been made through bushing 10. Figure 5. Using the guidance of the new surgical instrument, the osteotomies are made one by one from patient right to left
