Manufacturer Narrative

The handpiece has been checked visually and functionally against the valid specification.During the test run it was already found that the ball bearings have been grinding and binding and the heat up was reproducible.This is already an indication that the ball bearings are worn out, which could be confirmed after disassembly of the instrument.After disassembly black residue was found which is a sign that the reprocessing after the treatment is not done according to the ifu.Root cause for the heat up was residue in the bearings and worn bearings.Both causes higher friction and hence heat up.To avoid such issues the ifu contains already several notes, warnings and requests how to prepare the handpiece for each treatment and how to use it: warning: hazards for the care provider and the patient.In the case of damage, irregular running noise, excessive vibration, untypical warming or when the cutter or grinder cannot be held.Do not use further and notify service.Caution: burning hazard from hot instrument head or hot instruments cover.If the instrument overheats, burns may arise in the oral area.Never contact soft tissue with the instrument head or instrument cover the following guidelines must be observed to ensure save use of the electrically driven contra-angle handpieces: the service instructions for contra-angle handpieces must be precisely following when using kavo spray or quattrocare care systems.Before each use, the contra-angle handpiece must be checked for external damage.Before each use, perform a test run with the contra-angle handpiece, and watch for atypical heating and unusual noise and vibration.Immediately stop using contra-angle handpieces that act unusual.Never press the pushbutton during operation.This also includes lifting the cheek or tongue! to ensure proper function, the medical device must be set up according to the reprocessing methods described in the kavo instructions for use, and the care products and care systems described therein must be used.Kavo recommends specifying a service interval at the dental office for a licensed shop to clean, service and check the functioning of the medical device.This service interval depends on the frequency of use and should be adjusted accordingly.
