I've seen a case where a zirconium crown installed on the second molar of a patient vibrates at certain frequencies of vocalization (e.g., nasal consonants, humming higher-frequency notes, i.e., in the second octave of the solfège naming convention: Fa–Sol-La-Si) the crown resonates and makes a buzzing sound (loud to patient but nearly imperceptible outside of the mouth).

Is this a known phenomenon? Do you know of any other examples where this has occurred with a zirconium crown?
