T.T.S is an ergonomically designed, easy to use digital instrument that can be used for measuring with good precision detal models for "Tip and Torque"
The Tip & Torque Surveyor is an instrument for measuring torque and angulation of the facial surface of mal- occluded teeth. The Tip and Torque Surveyor has the advantage over the TARG of being able to move around the teeth and measure them, not just setting them when we align the middle of the blade with the tooth’s FA points. The slightly curved blade helps us compensate for awkward tooth morphology. It consists of an anodized aluminum base, including a stainless cover plate for the working area to reduce possible wear. It has a vertical stainless steel column and 3 main assemblies, which are: Angulation adjustment assembly: the model is placed on a fixed surveyor base and the blade moved around each individual tooth aligning the middle of the blade with the FA point (midpoint of each tooth on its long axis), or the model is placed on an adjustable survey base and tipped on the surveyor until the blade meets with the long axis of the labial face in the same manner as before. Then the angulation adjustment knob is rotated until the blade is exactly aligned to the middle third of the tooth parallel to the long axis of the labial face to read off ‘Tip’ or the ‘Tip’ is set to a predetermined value. The angulation adjustment knob can then be locked into position. Vertical and horizontal pencil facial markings are used as a reference check. The LCD display shows the angulation measurement to 0.5°, which is more than sufficient accuracy in Orthodontics due to all the clinical variables that come into play via the bio-mechanics. It has a range of more than +50° to -50°. The precision accuracy is achieved using rotary encoders and, low backlash mechanical movement plus unique signal conditioning electronics.
Torque adjustment assembly: On the shaft of the torque adjustment knob is a gear wheel connected to rack dovetail guide that slides in an arc movement. Rotating the torque adjustment knob moves the blade in arc of +50° to -50°. The blade is at 0° with an average curvature. The blade is either moved around a stone dental model on a fixed horizontal table or the model is tipped on the adjustable surveyor base until the blade meets with the long axis of the labial face is exactly aligned to the middle third of the tooth to the predetermined tip & torque. The torque adjustment knob can then be locked into position Vertical and horizontal pencil facial markings are used as a reference check. The LCD display shows the torque measurement to 0.1 ° with the range of +50° to -50°. The precision accuracy is achieved using rotary encoders and, low backlash mechanical movement plus unique signal conditioning electronics.
