Recommended Drilling Parameters of Tungsten Carbide Round Drills for the Most Optimal Bone Removals in Oral Surgery

Figure 1

During the experiment, a custom made “drilling tower” was attached to a physio-dispenser unit and a surgical handpiece. After setting the bone surface contact (with a screw indicated by the green arrow), the use of the switch-lever (black arrow) allowed the handpiece to begin the axial movement and simultaneously started the time measurement, while another induction switch stopped the time measurement when the predetermined 5 mm depth was reached. Temperatures were measured by thermocouple probes connected to a registration unit. The thermosensor probe was embedded into rubber isolation tube (see magnified square) to eliminate cooling liquid’s disturbing effects.
