Handpiece maintenance system and dental instruments for predictive maintenance

A dental handpiece maintenance system for maintaining a handpiece comprising:

• a housing;
• an entrance for providing access to a chamber in the housing;
• at least one maintenance coupling disposed in the chamber, the maintenance coupling sized to receive a handpiece;
• an accelerometer to sense vibration and/or a temperature sensor to sense temperature of the handpiece located inside the chamber;
• a support arm disposed to support the handpiece connected to the maintenance coupling, the support arm including the accelerometer and/or the temperature sensor;
• and
• an electronic processor that is configured to:
• receive inputs from a user interface,
• operate a maintenance cycle for the handpiece disposed within the dental handpiece maintenance system,
• operate the handpiece in a diagnostic cycle while receiving one or more conditions of the handpiece, and
• determine a predictive maintenance condition for the handpiece from the one or more conditions received during the diagnostic cycle.
