Mechanical and Histological Effects of Resorbable Blasting Media Surface Treatment on the Initial Stability of Orthodontic Mini-Implants

Table 6

Removal angular momentum of machined group and RBM group at 2 weeks and 4 weeks after the implantation.

Time	⁢Removal angular momentum (Ncms)				value
	⁢Machined group		⁢RBM group
	Mean	SD	Mean	SD
2 weeks	6.45	1.67	7.9	1.86	0.026
4 weeks	13.62	5.07	12.52	2.93	0.489

Removal angular momentum was the integrated removal torque during the first half turn.
SD: standard deviation.
