Table 2. Mechanical testing results of pullout tests and torsion tests (mean±SD).

Parameter	SS (6 weeks)	RS (6 weeks)	SS (12 weeks)	RS (12 weeks)
Maximum pullout strength (N)	1429.67±28.09	1470.1±59.13	2555.03±71.08^*	2668.38±107.66^*
Maximum torque (Nmm)	941.15±41.29	1729.25±68.07^*	943.88±53.25	1753.67±63.60^*
Stiffness (N/mm)	412.35±12.04	454.12±29.24	589.57±30.70^*	671.82±20.01^*
Angle-related stiffness (Nmm/degree)	33.33±7.83	202.48±49.87^*	31.77±3.12	236.90±57.42^*

*For the maximum pullout strength and stiffness, significant difference was observed between SS and RS in the same group, and for the maximum torque and angle-related stiffness, there was significant difference between the two groups at either time point.
