Influencing parameters & decisions to be taken When taking impressions, consider the different parameters which might have an influence on the impression taking procedure like technique and components: • Tissue-level or bone-level implant • Connection type (external hex, internal tri-channel, internal conical) • Implant-level or abutment-level impression • Single unit or multiple units • Abutment-level / abutment type: Snappy, Multi-unit, other • Open-tray and closed-tray procedures • Soft tissue condition / emergence profile • Impression material • Standard or individual impression tray

Impression material & procedures • Usually elastomeric impression materials are materials of choice (addition reaction silicone, polyether) • A standard impression tray can be used (for open tray procedure drill holes in the tray at the planned positions of the impression coping) • An individualized impression tray is recommended to better fit the anatomy of the patient and for difficult anatomical situations • Closed tray and pick up techniques are applicable for ‘small/easy‘ cases (e. g. single units) • Open tray techniques are recommended for larger restorations (e. g. bridges)
