A Novel Technique for Replicating the Profile of an Interim Implant-Supported Single Crown on the Definitive Prosthesis

Figure 1. (a) Preoperative intraoral illustration. (b) Radiographic preoperative view. Figure 2. (a) Implant placement. No flap has been reflected. (b) Preliminary healing with the interim restoration. Figure 3. (a) Stone cube is used to secure an implant analogue. An impression of the interim prosthesis is made by using addition silicone (IAS). (b) A custom impression coping is made with autopolymerized acrylic resin and a prefabricated impression coping. The IAS is used to contour the custom impression coping.
