Take a bite registration prior to numbing patient.

Record shade as soon as patient gets in the chair to avoid dehydration which can happen within minutes.

Take photographs as soon as patient gets in chair. Use shade tabs in photos and be sure to capture tab info.

Record and communicate in writing or with photographs the shade of the prep (referred to as stump shade) for any type of metal free case.

Email or include with case quality, useful photographs.

Provide models or impressions of pre-op or accepted provisional, especially on on anterior cases, multi unit cases and mal-occlusion cases.

Double check the occlusal clearance. Use a boley gauge to measure temporaries prior to cementing or make a mousse bite registration on the prep area and measure it. Make any necessary adjustments to preparation for adequate clearance prior to impression.
