Your original models are returned with each case as well as any PVS impressions and trays. You may note our repairs and relief for undercuts to your original models which are done prior to producing the master construction models. We also return the master set-up model with the teeth reset to the position reflected in the last appliance in the series. Please keep these models until the end of treatment because they may need to be returned to the lab in case an issue arises during treatment.
For Continuation aligner cases we always recommend returning the original set-up models with the new current model so we can compare the intended results to the patient’s current condition. Therefore, on cases where there might be additional aligners required, we suggest retaining the original set-ups we return with the case.
