Reproducing the accurate intraoral relationship of an implant through impression making is first step in achieving accurate fit prosthesis. Traditionally impression techniques used in implant dentistry can be classified into closed tray and open tray impression techniques. Open tray impressions are considered to be more accurate as compared to the closed tray impressions in cases with multiple implants. It requires long impression copings which are picked up in the impression during impression procedure thereby reproducing the exact relationship of an implant. Present article describe a modified direct abutment open tray impression technique utilizing applicator tips in absence of long impression copings.

Abutments can be prepared in fixed dental prosthesis using horizontal and vertical preparation techniques. In vertical preparation abutments are prepared without a finish line by introducing a diamond rotary instrument into the sulcus to eliminate the cementoenamel junction and creating a new prosthetic cementoenamel junction. Vertical preparation technique in fixed dental prosthesis allows us to retrieve biologically compromised situations. With vertical preparations and over contoured provisional crowns, one can control zenith positions and thicken gingival biotypes. This in time gives us long lasting, stable tissue aesthetics around definitive restorations. This article describes 2 patients whose dental abutments were prepared using vertical preparation technique and 12 months follow up for restoration of teeth in aesthetic zone. Vertical preparation technique provides feather edge preparation and with interaction between preparation, restoration and gingiva aid in gingival thickening and adaptation to new prosthetic cementoenamel junction (CEJ) achieving soft tissue stability over long term.
