How long do you keep models sent to lab for crown/bridges?

As soon as a crown is seated, we discard the models.  The models no longer serve any purpose and take up space in the office.  Should the crown need to be remade, the tooth would need to be reshaped and a new impression taken, so no need to keep the model.

hi,

The lab usually keeps the models about 7 to 10 days or how ever long it takes them to make the crowns or other dental work. Its then returned to your dentist with the finished product and from there we discard the models.

Models are typically discarded after the prosthetics are delivered as there is no use for them.
