Passive fit between prosthesis and implants or abutments is a significant factor in preventing mechanical and biologic failures of implant-supported prostheses. Therefore, impression techniques must transfer the 3D implant position as accurately as possible for a correct superstructure fabrication. A novel impression protocol that uses an individualized open tray design is proposed. It allows the clinician to splint the transfers between the copings, outside the impression area, and to the tray itself to create a rigid monoblock. Thus, distortions produced by the tear of impression material or by transfer abutments’ micromovements during tray retrieval are limited and superstructure misfits are minimized. This technique is specifically recommended for long spanning or completely edentulous patients.
