case report _ full mouth reconstruction Using CAD/CAM for a combination approach to full mouth reconstruction Author_Dr Ara Nazarian, USA _Introduction N ow more than ever, it behoves dentists and laboratories to work together as part of an interdisciplinary and collaborative team to coordinate treatment, select ideal restorative material(s), and plan cases, particularly those involving full-mouth reconstructions1, 2. Fortu- nately, a number of digitally based technologies can be incorporated into the treatment thorough diagnostic and treatment planning processes,3 as well as used for fabricating various components of treatments. When used in combination with a systematic and collaborative plan for preparing and executing treatment, these tools can enable the team to achieve success when restoring a patient’s smile to proper form, function, and he- alth. Simultaneously, other advances in techno- logy and material science have provided dentists and laboratories with restorative zirconia op- tions that can be cost-effective and aesthetic alternatives when full-mouth rehabilitations are needed4, 5. In fact, computer-aided design/ computer-assisted manu facturing (CAD/CAM) make it possible for laboratories to collaborate with dentists to deliver monolithic zirconia re- storations with individual characterisations that demonstrate high flexural strength and excellent long-term stability (e.g. Zenostar, Wieland, Ivo- clar Vivadent)6-8. Because this material can be milled at the laboratory from single blocks using CAD/CAM technology, laboratories and their dentists can collaborate directly regarding the aesthetic and functional characteristics required. The ceramist can then complete the restorations using stains, glazes, and colours to finalise the restorations. Overall, the foundations of this col- laborative process are the digital CAD/CAM and communication technologies (e.g. digital photo- graphs, digital radiographs, intraoral scans, 3-D restoration design software) that enable labora- tory technicians to virtually design the zirconia restorations. These same technologies also faci- litate the workflow by powering the milling of monolithic blocks into crowns and bridges, with subsequent sintering and stain characterisation requiring less time7, 8. _Case report A woman in her mid-60s was referred to the dentist because she was dissatisfied with the appearance of her smile (Fig. 1). The initial dia- gnostic evaluation during the first appointment included a series of digital images with study Fig. 1_Retracted preoperative view. Fig. 1 18 3_2017
