Figure 2: Technical way to manufacture the surgical drilling template, applying the prosthetically-guided planning concept by using digital planning software.
A: Radiographic template with barium sulfate tooth 014 and the radiopaque markers. B: The radiopaque markers in the software display. The correction of the automatic detection is done manually if necessary. C: Planning data of an implant regio 047. On the left in the upper the selected implant system with the corresponding length and diameter can be seen. On the right and bottom left, the data important for fabricating the surgical guide are displayed. D: After setting the drilling table in 4 planes (A, B, C, D) according to the planning data, the drill hole is made in the drilling template. The metal die is then glued in place. E: Planning interface of the software. The implants were selected according to manufacturer, type, and diameter and placed in the jaw in the ideal prosthetic position shown by the X-ray template. The position data were sent to the laboratory for fabrication of the surgical guide. If there was no bone available, the bone augmentation was planned or, as in the present example, inserted paranervally to avoid costly vertical augmentations. F: Representation of the Straumann Guide System. Similar to the Steco system, however, here the drill sleeves are located on a guide tray to simplify handling. © Institut Straumann AG
