What Makes Electric Handpieces Superior? 
Electric Handpieces Cut with Greater Precision
The rigid bearing suspension system of the Apex Contra Angles combined with the constant speed capability of the Apex electric motor means more precise cuts yielding finer margins with less vibration and patient trauma.
The Apex motor features an electrical feedback system that detects load at the bur and automatically increases motor voltage to maintain bur speed. This means you get smoother, more precise cutting.
The rigid, metal to metal bearing suspension system of the Apex Contra Angles compared to the soft O-ring based suspension system of a typical highspeed means less bur deflection and smoother, more precise cuts with better finishes.
The Apex Feedback System Ensures Constant Cutting Speed
for the Ultimate in Precision and Control
- A load is applied to the tooth surface at the bur
- The sensor in the back of the Apex Electric Motor realizes the load
- The Sensor instructs the control unit to increase voltage to the motor
- More voltage is sent to the motor
- Motor speed remains constant
- Cutting speed remains constant
Electric Handpieces Double the Cutting Power
Inherent in the Apex Electric System is twice the cutting power of a typical highspeed handpiece combined with virtually unstoppable torque. Since you don't have to wait for highspeed rpm recovery, you'll quickly replace the typical highspeed swiping attack and retreat cutting movements with the firm, steady, uninterrupted cutting stroke of the electric. Double the cutting power combined with unstoppable torque means faster, more efficient cutting and increased practice production. And, the steady, uninterrupted electric cutting stroke will result in better cut control, greater precision and superior preparations for your patients.
The Apex Electric System eliminates the typical air highspeed whine. Its lower frequency gearing sounds are less objectionable and more pleasing to you, your staff, and your patients.
Studies have shown that the lower pitch of the electric motor is more tolerable than high frequency highspeed handpieces. The Apex 200LS contra angle was used for testing.
