A digital workflow for the fabrication of an immediate implant-supported interim restoration

Abstract

Immediate interim restorations in the esthetic region are usually fabricated in situ by using the pick-up technique, which is time-consuming and has a potential for cross-infection. This article describes a rapid and precise workflow for the fabrication of an immediate implant-supported interim restoration. A cast with gingival contours and an extended tube to accommodate the implant analogs is generated preoperatively based on the virtual implant planning and a predesigned restoration. After guided osteotomy and implant insertion, the actual three-dimensional (3D) implant position is transferred precisely from the mouth to the printed cast by using the surgical guide. This technique can achieve the rapid and precise fabrication of the interim restoration with guidance immediately after the surgery, decreasing the risk of cross-infection and reducing clinical steps and time.
