Electric handpiece attachments or contra angles don’t rely on air pressure to rotate the bur like high-speed handpieces do. Instead, they have gears that are turned by an electric motor.
The first components that tend to fail in an electric contra angle handpiece are the two small bearings attached to the spindle in the head of the handpiece. With prolonged use, these bearings will wear down and create friction which in turn heats up the head of the handpiece. If you notice the handpiece heating up, stop using it immediately and consult a professional. In some cases, it may be possible to rebuild the spindle and drive shaft by replacing the bearings, rather than opting for a more expensive overhaul.
Our team at Handpiece Xpress will thoroughly inspect your electric contra angle handpiece when you send it in for repair. We’ll then let you know if a rebuild would be beneficial, or if it would be better to get a complete overhaul.
The FDA has issued an advisory regarding the potential for patient injury due to improperly maintained or failing speed-increasing contra angle attachments. Friction in the internal bearings and gears can cause overheating and possibly burn a patient. Minimize heat by following the manufacturer’s lubrication and maintenance procedures and confirming that there is adequate air and water flow during use.
FEEL – Insert test bur and manually rotate it between your fingers. You should feel the bur rotating freely.
LISTEN – Connect attachment, then turn on cooling air, water, motor and gradually increase speed to maximum level (40K on control box panel). Run for 30 to 45 seconds without a load and listen for unusual grinding or clicking noises when operating in forward and in reverse.
TOUCH – While running the handpiece at full speed, touch the head and neck areas to check for excessive heat. It should feel cool to the touch.
