A key factor to success and longevity of implant prosthesis is an accurate fit which can be achieved through a proper impression technique. Several impression techniques have been proposed to provide a cast that will ensure accurate fit of prostheses on Osseo-integrated implants. These include abutment level impressions, indirect (closed tray) and the direct (open tray) techniques for implant level impressions and splinted and non-splinted technique for open tray impressions. Out of the available materials, polyether and vinyl polysiloxane are commonly used for impression techniques. Whereas, for splinting copings for open tray technique materials like resin, plaster, wax and others have been suggested. However, each clinical situation demands a proper technique requiring minimal time, easy to perform, inexpensive, comfortable for the patient and with best results which calls for a thorough understanding of various impression materials and techniques for their best utilization.
