Maximum torque (Ncm) and total energy (J) during insertion and removal.

	Group	Type of pilot drilling		Significance
		Self-drilling	Self-tapping
		(Mean ± SD)	(Mean ± SD)
Maximum insertion torque (Ncm)	DM	9.88 ± 1.30	9.38 ± 2.76	NS
	Control	10.75 ± 1.20	10.75 ± 1.83
Total insertion energy (J)	DM	3.56 ± 1.01	2.27 ± 0.63	Self-drilling > self-tapping
	Control	3.42 ± 0.54	2.55 ± 0.47
Maximum removal torque (Ncm)	DM	4.44 ± 1.21	4.28 ± 1.68	NS
	Control	4.13 ± 1.38	4.13 ± 2.03
Total removal energy (J)	DM	0.52 ± 0.15	0.50 ± 0.08	NS
