Template-guided Endodontics A root canal preparation can be difficult because it cannot be controlled. 3D Planning With a 30 planning software the drilling channel is defined (e.g. with coDiagnostiX™ or other systems). Drill and sleeve geometry can be integrated in the software. StecoGuide Endo-Sleeve Drill and sleeve geometry can be integrated in the software and can be inserted into a milled or printed surgical template. The sleeve-guided root canal processing offers predictable security. Guided root canal processing The ATEC twist drill is precisely guided by the StecoGuide Endo-Sleeve.
