Clinical Tip
Two minimally invasive approaches with different kinematics. TruNatomy is a rotary system at 500 RPM / 1.5 Ncm whose 0.8 mm maximum flute diameter and regressive tapers spare peri-cervical dentin; R-Motion is a reciprocating system with a thinner core (manufacturer data) that runs on any motor with a counter-clockwise reciprocating mode. Choose TruNatomy for rotary conservative shaping with its Glider, R-Motion when you prefer reciprocation.
