A dental handpiece is a hand-held, mechanical instrument used to perform a variety of common dental procedures, including removing decay, polishing fillings, performing cosmetic dentistry, and altering prostheses. The dental handpiece itself consists of internal mechanical components which initiate a rotational force and provide power to the cutting instrument, usually a dental burr. The type of apparatus used clinically will vary depending on the required function dictated by the dental procedure. It is common for a light source and cooling water-spray system to also be incorporated into certain dental handpiece; this improves visibility, accuracy and overall success of the procedure.
Dental handpiece is divided into high-speed dental handpiece and low-speed dental handpiece. High-speed dental handpiece also known as high speed mobile phone, high speed pneumatic turbine mobile phone, dental drill mobile phone, etc., is a commonly used medical equipment in the department of stomatology treatment.Its working principle is to compress the air as the power, drive the wind wheel to rotate at high speed, so as to drive the dental car needle to complete the work of drilling and grinding the tooth.The speed of the high-speed dental handpiece reaches more than 300,000 RPM, which is mainly used for treatment and repair (such as drilling holes and cutting). Low-speed dental handpiece is divided into straight machine and bending machine, the straight machine is used for polishing, is in the treatment of the mouth, bending machine is the treatment of the mouth.
The working principle of dental handpiece is similar to that of windmill. The flowing air with certain pressure enters the stoma along the main airway, and the high-speed airflow generates thrust on the blades of the wind wheel, so that the wind wheel drives the mandrel to rotate at a high speed, and the continuous airflow makes the wind wheel rotate at a constant speed.The car needle is held by the mandrel, and the mandrel is tightly connected with the wind wheel, so the rotation of the wind wheel drives the car needle to rotate synchronously, to cut the tooth body to remove caries and bad tissue, or to prepare porcelain teeth, can also be used to polish the denture (but not too much force, otherwise it will damage the dental handpiece), after the work of the residual air out of the phone.
Dental handpiece is a necessary instrument for the treatment of oral diseases. It is complex in structure and precise in manufacture. During the treatment, dental handpiece will be contaminated by the patient's saliva and blood.When the turbine dental handpiece stops running, the negative pressure will also suck blood, saliva and debris back into the phone along with the air and water, and distribute them to bearings and ball bearings, becoming an important medium for cross-infection.On the other hand, if the blood, saliva and debris inside the phone are not cleaned before sterilization, they will harden and carbonize at high temperature, which will damage the mechanical parts of the phone.
