Handpieces FAQs
1. What's the difference between high speed and low speed handpieces?
1. What's the difference between high speed and low speed handpieces?
The rotational speed of high-speed dental handpieces can reach up to 450,000 RPM and are best for cutting enamel or preparing cavities. low-speed handpieces run at around 10,000 to 40,000 RPM and are better suited for polishing, endodontics, and finishing procedures.
| Feature | High Speed Handpiece | Low Speed Handpiece |
| Speed Range: | Up to 450,000 | 10,000 to 40,000 |
| Torque: | Lower | Higher(especially electric) |
| Noise/Vibration: | Higher | Lower |
| Cooling Required: | Yes(water spray) | Not always |
| Bur Attachment: | Friction Grip(FG) | Latch-Type(RA)or Handpiece(HP) |

2. What are the differences between Contra Angle Handpiece, Straight Handpiece and Motor?
2. What are the differences between Contra Angle Handpiece, Straight Handpiece and Motor?
Low speed handpiece consists of three parts: Contra-angle handpiece, Straight handpiece, and Motor. Their functions and differences are as follows:
- Contra-angle handpiece is designed for root canal treatment and must be connected to a motor to operate. It comes in two types: push-button and latch-type. Its technical specifications include a working air pressure of 0.3–0.35 mpa, a bur standard diameter of 2.345–2.355 mm or 1.595–1.6 mm, and a speed of at least 180,000 rpm. It supports multiple speed ratios, including 1:1 (equal speed), reduction ratios such as 4:1, 10:1, 16:1, 20:1, and 64:1, as well as an increase ratio of 1:5. Water output is available via either an internal or external water channel, and the light source can be LED or fiber optic.
- Straight handpiece is used for polishing and grinding prosthetic teeth, and also requires a motor connection to function. Its working air pressure is 0.3–0.35 mpa, with a bur standard diameter of 2.345–2.355 mm and a speed of at least 180,000 rpm. It operates at a 1:1 equal speed ratio.
- Motor serves as the power source, connecting to either the straight or contra-angle handpiece to drive operation. It operates at a working air pressure of 0.3–0.35 mpa, with a speed of at least 18,000 rpm, and is available in 2-hole or 4-hole models.
3. Cartridge Performance Warning Signs:
3. Cartridge Performance Warning Signs:
- Decreased rotation speed/reduced cutting efficiency (insufficient torque)
- Abnormal shaking or seizing of the bur
- Abnormal water/air spray
- Severe overheating
- Abnormal beeping, etc.
