All about Dental Handpieces
From ordinary dentistry to digital dentistry, Dental handpieces have always been one of the most important tools used in clinics. The only difference we can now see is much improvement that really enhanced the existing workflow.
These are majorly categorized as Air Driven Handpieces and Electric Handpieces further perform with varied characteristics.
How Air Driven Handpieces work?
Air Driven handpieces basically use compressed air to spin the turbine, which further spins the dental bur
How Electric Driven Handpieces Work?
Electric driven handpieces consist of internal motor which helps in spinning the dental bur in controllable speed.
Many times user asks the comparison in between these two on the basis of their performance but it cannot really defined that which one is better, because each can fulfill different need; depending on the type of procedure you follow.
But yes, there are some characteristics on the basis of which user can choose the specific type of Handpieces.
Speed – Air driven handpieces can achieve maximum speed depending upon the amount of air coming through as their RPMs is governed by input air only. On the other side, Electric handpieces are already considered as high speed handpieces and can be worked upto approximately 200,000 RPM.
Consistent Torque – Air Driven handpieces usually get slow down while working on dense materials but electric handpieces do not experience drop in torque, no matter what material you are cutting.
Variable Torque – Some electric handpieces allow you to change the torque settings. This allows you to do other variable procedures with the same unit such as endodontics.
Speed control with electric – As already mentioned above that user can control the speed of electric driven handpieces, user can take the work from this similar to air rotors. That means, if you want to slow down the speed without keeping the torque constant, then these electruc driven handpieces will be the best option.
Concentricity – Normally an air rotor experiences wear over the period of time due to spinning of turbine and henceforth, it somewhere lost its concentricity. On the other side, electric handpiece provide smoother preparations as it uses gears which further allow the bur to remain in more concentricity.
Noise – You can perform silent operation with electric handpieces compared to air driven handpieces. Maximum noise level is 6db.
Weight – Micromotor handpieces are little heavier than air driven handpieces.
