The restoration of dental implants requires a sound knowl- edge of restorative dentistry, pros- thodontics and periodontology. Traditionally, this has been carried out with an analogue impression taken with an impression coping either via an open or closed tray im- pression technique. A skilled techni- cian then fabricates this restoration over a 2- to 3-week period. The time and skill required for these restora- tions both from the clinician and technician command high fees for the patient. This case report highlights a novel method of restoring implants utilis- ing the modern advances in digital intraoral scanning and chairside milling. It illustrates how an aesthet- ic single implant retained crown can be provided chairside without the need for analogue impressions (Figs. 1 & 2: Pre-operative condition). Following a discussion of the options for replacement of LR6, the patient elected for an implant retained so- lution. A MegaGen AnyRidge 4 x 10 mm implant was placed utilising a surgical guide for position of the pilot hole. An immediate tempo- rary crown was fabricated using the MegaGen fuse abutment and DMG Luxatemp. A silicone index of the di- agnostic wax-up was fabricated and the temporary crown was polished and taken out of occlusion while the implant fully integrated (Fig. 3). Traditionally, capturing the detail of this soft tissue profile with analogue methods is complicated and time consuming; however, utilising a digi- tal intraoral scan (CEREC Omnicam) a “gingival mask scan” can be taken to accurately replicate this soft tissue and use it to guide the subgingival emergence profile of the restoration (Fig. 6). Following 3 months of integration, the patient attended the practice for the restoration of the implant with a definitive crown. During this period, the soft tissue had been given time to mature and a beautiful molar soft tissue profile had formed (Figs. 4 & 5). Following removal of the temporary crown, a TiBase was placed into the fixture head and a scan body used as a reference point for the scanning of the implant (Figs. 7 & 8).
