A Technique to Simultaneously Fabricate Multiple Custom Impression Posts for Implant‐Supported Restorations in the Esthetic Zone

Abstract

Peri‐implant transmucosal tissue, an essential element of peri‐implant esthetics, is critical to the success of prostheses in the esthetic zone. The optimal transmucosal tissue profile can be transferred to the master cast with the aid of custom impression posts. In this clinical technique, the initial cast used to fabricate provisional prostheses was conveniently used to aid in the time‐efficient fabrication of multiple custom impression posts simultaneously using self‐cured acrylic resin. This technique also applies to single restorations. In addition, the use of an initial cast as holder makes it easy to transfer custom impression posts to the mouth accurately and efficiently.

Management of Peri-implant Soft Tissue Emergence Profile and Accurate Transfer Technique

“…Immediate temporization has advantages including the ability to provide optimal aesthetics by guiding the tissue response during the healing phase, and facilitating the production of final restorations, as well as protecting patients' wellbeing and self-esteem [13,14,16,20]. After removing the temporary crowns, due to the rapid depression of the peri-implant soft tissues, several impression techniques have been reported that duplicate the soft tissue form to the final restoration in a more appropriate method compared with the traditional impression technique [15,19].…”

“…The indirect technique that requires extra-oral additions of resin to impression posts reflects completely the form of the peri-implant mucosa surrounding the temporary crowns and allows delivery to the laboratory [15,18,19]. The primary benefit of the extraoral acrylic resin addition is the none of connection of the resin with the tissue.…”

“…After obtaining the emergence profile, it is a matter to be considered to reflect the soft tissue form to the impressions will be taken. Several techniques have been described such as using provisional restorations and/or customized impression copings to accurately duplicate the peri-implant emergence profile [15][16][17][18][19]. In the present article, the one-step formation of the periimplant emergence profile, and an indirect impression technique to reflect the soft-tissue form obtained, was described via case reports.…”
