Ensure the drill has a resistance free path of insertion by pumping the drill in-and-out of the drill guide prior to drilling. Each drill should be advanced as far as possible through the drill guides and pilot sleeves prior to initiating drilling. Use short, light strokes to progressively advance the drills to depth with minimal pressure on the drills. Profuse irrigation throughout the drilling sequence is necessary to provide lubrication and prevent overheating. Use an in-and-out pumping action (Figure 3) to help clear flutes and drill guides of any bone debris. Drills should not be completely removed from drill guides or pilot sleeves during pumping. When finally removing drills frommaster cylinders and drill guides, the drill should not be rotating. Suction and irrigation should be used between drills to remove debris from the instruments, master cylinders and the osteotomy. Warning: Failure to follow these steps can cause the drills to bind in the drill guides. Avoid applying lateral pressure to the drill guides or pilot sleeves by ensuring the drill path is in line with the drill guide (Figures 3 & 4). • In cases where the patient has limited opening/interocclusal space, components may be stacked out of the mouth. Insert the drill in the handpiece and place through the appropriate drill guide. Then insert the assembly into the master cylinder, sliding the drill guide down into place (Figure 1). Ensure that the drill guide is evenly seated before initiating drilling (Figure 2). Figure 1 Figure 2 Figure 3 Figure 4 When using a pilot sleeve, advance the 2.0mm pilot drill without a drill guide. Once the initial osteotomy has been drilled, remove the surgical guide and proceed with the manufacturer’s standard protocol for implant placement. Surgical guide with pilot sleeve
