What do we do with your highspeed dental handpiece when we receive it for repair? Personally I start with a good visual inspection looking for obvious damage that might warrant repair. If all is OK there, then a burr is placed in the chuck and removed several times. This will let me know if the chuck in engaging. A pull tester is then used to check the tightness of the chuck. If the chuck fails this test, then the turbine will be changed. The complete turbine must be changed when failing this test to protect you and the patient from the burr disengaging. The bearings will also have to be changed in this case because even if the bearings are still good, they cannot be pulled and used again. If the unit passes the pull test, the unit is hooked up to an air station. Running the unit at 32 PSI, and listening carefully it can be determined if the bearings are defective. This is also a good time to test the water jets. If the bearings must be replaced, then the back cap is removed using a back cap tool. This will expose the turbine and it can be removed at this time. Once the turbine is removed the "O" rings must also be removed. At this time the inside of the drill head and the back cap will be cleaned completely. All debris and particulate must be removed. It can also be determined how well your handpiece is maintained based on the condition inside the head of the handpiece. Once cleaned the "O" rings will be replaced with new ones. If there are any washers and/or clips they will be replaced at this time. If there was a water problem then using a special tool, the front of the handpiece can be removed and the seals replaced. Also the jets can be cleaned at this time. Now the turbine can be rebuilt. The bearings must be pressed off the turbine using an arbor press. Once completed the impeller and chuck will be cleaned. Using the proper ceramic bearings, they will be pressed into proper position using the correct press pin. Now the turbine is complete and can be installed back into the handpiece. Place the rear bearing into the back cap and holding the back cap place the turbine into the head and screw the back cap into place. Insert a burr and move it around a bit to position the turbine. Hook up and test. If performed properly the dental handpiece repair will be completed. There are other problems that can occur with the dental handpiece such as fiber optics and water lines. However the repair described above is the typical repair we see with the highspeed dental handpiece. At Bauer Dental we only use ABEC7 rated Ceramic Bearings in all of our repairs. We offer this service to you for only 69.95 per unit for a turbine basic rebuild. This is ceramic bearings, clips,washers, "O" rings, and cleaning. If the unit requires a complete turbine we can build and replace the turbine for $130.00 in most cases.
