Still not sure of the ideal #Air_Rotor for your #Dental_Practice? Don't worry we are sharing the factors you should consider for trouble-free operation using the right Handpiece.

1. Introduction:
Air rotors are an essential extension of a dentist’s working hand, and today’s practitioner is
tremendously reliant on the rotor’s optimum efficiency to provide a smooth and functional
practice. The intricate assemblage of quality pieces in a modern dental handpiece move in a
perfect synchrony with exceptionally high speed to provide faster cutting efficiency to the
clinician. By minimising patient trauma, this strong cutting ensures a clean preparation
margin for better retention of dental restoratives.
Since a handpiece is one of the most commonly used instruments in a dental office, while
selecting a dental handpiece there are a few factors which a clinician needs to focus that
will help in up hilling his dental practice. It is essential to select high-quality and high-
performance handpieces for the smooth operation of the practice. Choosing a high-quality
handpiece can help dentists work more efficiently, minimize patient stress, and lower
operating costs.
Wondering How to Select an Air rotor?
When purchasing handpieces, it needs to be ensured to get a product that complies with
regulatory requirements. On the internet many counterfeit and non-compliant dental
handpieces are available.
When the clinician purchases any such handpiece, he may face several issues in the dental
practice:
• The handpiece may break down very often
• The handpiece may require several repairs due to non-standard rotor
• Excessive vibration may lead to unnecessary patient trauma

2. • Bearing failure or turbine failure
• Risk of cross-contamination
• Tissue necrosis
• Excessive heat may lead to inability to perform dental procedure for longer duration
• Hand fatigue in clinician
• Visibility compromisation
• Scratches on the dental handpiece
To avoid such situation in the dental practice, it is essential to invest in a high-quality dental
handpiece that not only save you time in treatment procedures, but also prevent from the
risk of cross-contamination in dentistry.
Factors To be Considered While Choosing an Air Rotor:
The patient’s as well as the clinician’s own safety should always be kept in mind while
choosing an air rotor. Investing in a high-quality handpiece will pay off in the form of years
of service that also help in improving the productivity of the dental professional in the clinic.
The following are some factors that needs to be considered while choosing an air-rotor:
1. Head Size:
High-speed handpieces come in a variety of head sizes. Most manufacturers sell a variety of
versions with large and small (miniature) heads. Depending upon the requirements of the
dental professional, the head size of the handpiece is chosen.
Smaller head size improves visibility and accessibility, especially in the posterior region of
the oral cavity and in paedo patients. Larger head size provides a larger turbine impeller
that produces more torque and strength. More cutting strength means less time spent
preparing teeth and faster treatment to the patient reducing patient clinical trauma.
2. Types of tubing connection:

3. There are various types of tubing connections in a handpiece depending upon the
functionalities, known as the hole system of the dental handpiece. But the most commonly
used hole systems are 2 hole system (Borden hole) and the 4-hole system (Midwest). The
holes are present in the base of the handpiece serving various functions.
2-hole handpiece: This type handpiece is considered as standard handpiece in developing
countries e.g., India, Asia etc. Large hole is for air and the smaller hole is for water.
4-hole handpiece: This type handpiece is considered standard in countries like U.S. &
Europe. It has 2 large air holes, one small hole for water and another small hole for chip air.
It ensures less noise.
3. Ball bearing material:
The dental handpiece performance is solely dependent upon the turbine performance. The
turbine has the bearings that help in smooth rotation of the bur and help in increasing
cutting performance.
Ceramic bearing has several advantages over traditional stainless steel bearings due to
which makes it more durable. It is 25% tougher, but also weigh less, due to which the
working efficiency of the rotor increases.

4. 4. Water jet Spray:
A water spray system in dental handpiece helps in providing extra cooling effect to the
prepared tooth and the tissues and help in prevention of tissue necrosis. It can be single
spray or multiport spray.
A multiport spray (usually three to four) emerging from the head of the handpiece is far
superior to a single spray system because it provides distribution of coolant water over the
entire surface which prevent overheating of the pulp. The abraded material is removed to
prevent obstruction of the view of the treatment site.
5. Bur chucking mechanism:
The chuck mechanism is to hold the bur in the handpiece firmly and help in smooth
rotation.
Standard Screw or Chuck Type: It requires a chuck or key to insert/remove the bur. The
chuck is attached to the hole on the head of the handpiece and rotated clockwise/anti-
clockwise for the bur to insert or remove respectively.

5. Push Button-Type: In this type of mechanism the bur is removed or inserted only by pressing
the thumb in the back of the head in the handpiece. More easier than chuck type handpiece.
6. Hygiene technology:
Cross contamination is now the most serious risk to face when using an Air rotor. It can
occur either via air or water. The Air rotor should have special mechanism to prevent the
entry of oral fluids and other contaminants into the handpiece which effectively reduce
possible internal contamination. If you want to know more about the “The Biggest problem

Conclusion:
The dental handpiece is an imperative tool for a dentist in every dental operatory. Choosing
a high-quality dental handpiece implies a better patient experience, more cost-effective
treatment and simultaneously protection from common transmissible infections. The air
rotors are improved in its functionalities, designs and technologies to provide the dental
professional a better hand feeling and faster treatment, also help patients in reduced stress
with its comfortable noise level. The more the performance of the handpiece, the better the
quality of the treatment and improved productivity of the dental practice.
