Work Instruction GUIDE-SYSTEM

Guide System 22 Pilot drilling (optional) A. For bone condensation in weak bone If bone density is insufficient at the implant site, a pilot drill hole can be set of 2.0 mm in diameter. This drill hole is laterally extended with osteo- tomes, the surrounding bone being compressed. The compression ensu- res increased primary stability of the implant. B. For improved guidance in BICORTICAL IMPLANTATION/IMMEDI- ATE IMPLANTATION In the case of a bicortical implant fixation or immediate implantation, the pilot drill hole can prevent the form drill from slipping off when it makes contact with the apical cortex or alveolar wall. The pilot drill hole there- fore provides additional guidance for the form drill. The pilot drill hole is drilled in ascending length (5, 7* respectively 9, 11, 13 and 16 mm) up to the desired implant length. Pre-drilling Drilling into the cortex is carried out using an internal irrigation Guide System pre-drill. This clearly defines the drill and implant axis insofar as no pilot drill hole has been made. *7 mm only with CONELOG ® SCREW-LINE implants with a diameter of 3.8 mm and 4.3 mm Pilot drill APPLICATION Drilling depth: 5.0 mm Pre-drill
