Making an implant-level impression using solid plastic, press-fit, closed-tray impression copings: a clinical report

An implant-level impression is often desired for designing and fabricating an implant-supported fixed restoration, especially when 2 or more implants have been placed. However, convergent implants placed too close in proximity pose several problems, starting with the impression. In situations of extreme convergence or close proximity, modification of conventional metal copings may be impossible. This clinical report describes the use and associated advantages and disadvantages of solid plastic, press-fit, closed-tray impression copings as a mechanism suitable to create an implant-level cast.
