Ultrasonic scaler introduction
- 2018-10-23-

Handheld devices that transmit the energy required for dental surgery using mechanical transmission. According to different power sources, it is divided into pneumatic and electric.

It is used to hold rotating instruments such as burs, drills, and gums, and drive its movement to achieve dental operations such as cutting, grinding, cutting, and drilling.

Basic use

The intended use of the ultrasonic scaler equipment should reflect the clinical indications and scope of action.

For example, removing dental stains such as calculus and plaque on the surface of the oral cavity; removing tartar and plaque from periodontal tissue.

Root canal treatment assisted function and cavity preparation assisted functions are limited to tooth root canal cleaning, swashing, and preparation of cavity shapes.

Product name example

Ultrasonic scaler, ultrasonic tooth cleaner, sandblasting scaler, powder cleaning toothbrush, pneumatic scaler, oral cleaning machine, root canal washer.

Structure and composition

Mainly composed of function control circuit, liquid circuit, handle, ultrasonic transducer, action head, power/power adapter (if any), foot switch (if any), etc.

The head for the ultrasonic cleaning function is called the working tip. Due to different application parts and implementation functions, the action head can include a working tip, a root canal, a bur, and the like.

working principle

The high-frequency oscillating circuit generates a high-frequency oscillating signal and acts on the ultrasonic transducer, and the ultrasonic vibration is generated by the inverse piezoelectric effect (or magnetostrictive effect), and the working tip is excited to generate resonance, and various effects generated by the ultrasonic wave will be used. Plaque on the surface of the tooth, stones or bacteria on the periodontal surface are removed.

Mechanism of action

The tip of the working tip is in direct contact with plaque and stones, causing scraping or shearing.

Ultrasonic jets and cavitation generated in this area.

The abrasive action of the stripped stone particles.

From the above three aspects, the plaque on the tooth surface and the bacteria on the stone or periodontal surface are eliminated.

At the same time, the flushing water jet from the tip cools the handle and the working tip and flushes the working surface to produce cooling, lubrication and rinsing effects.

It can improve the oral environment and prevent dental caries and periodontal diseases by removing plaque stones on the surface of the teeth.
