2. According to the type of connecting and connecting pipes, dental handpieces can be divided into two-hole dental handpieces (drive air and water); three-hole dental handpieces (drive gas, water, and atomizing gas), four-hole dental handpieces (atomized air and return air) and optical fibersix-hole dental handpieces (drive air, water, atomized air, return air and two electrode columns).

 

3. According to the exhaust way of dental handpieces, dental handpieces can be divided into internal exhaust (four holes and six holes) and external exhaust (two holes) dental handpieces.

 

4. According to the diameter of the head of dental handpieces, dental handpieces can be divided into large dental handpieces (The head diameter is φ12.2), medium dental handpieces (The head diameter is φ11.2), and small dental handpieces (The head diameter is φ10.2). Due to the different size of the head, the strength and use of the dental handpiece vary slightly.

 

5. According to the disassembling and assembling method of dental bur, dental handpieces can be divided into gland type and wrench type.

 

II. Low speed dental handpiece includes straightening machine, bending machine and motor

 

1. According to the way of water outlet, dental handpieces are divided into outer channel and inner channel.

 

2. According to the way of light, dental handpieces are divided into those without light and with LED light. LED luminescence is also divided into wind power luminescence or external generator luminescence

III. Common cleaning sterilization misunderstandings of dental handpiece

 

1. Can ultrasonic cleaning machine be used for cleaning dental handpiece?

 

The dental handpiece cannot be cleaned by ultrasonic, because the rotating part (bearing) of The dental handpiece needs to be adjusted for dynamic balance when leaving the factory. High-frequency ultrasonic oscillation will destroy the balance and cause damage to the dental handpiece.

6. Can dental implant handpiece and common dental handpiece be cleaned in the same way?

 

The dental implant handpiece is more difficult to clean because it has to change speed and contains two bearings inside. It is ideal to combine manual cleaning and automatic cleaning machine cleaning.

 

7. Can the dental handpiece be sterilized with all small pressure steam sterilizers?

 

Pressure steam sterilization is preferred in the cleaning of the dental handpiece. Only the type B pans can be used for sterilization of the dental handpiece of in small pressure steam sterilization, because there is an internal cavity in the dental handpiece.
