case report | about Dr Stavros Pelekanos graduated School of Dentistry, National and Kapodistrian University of Athens in Greece and received Doctoral promotion Dept. of Prosthodontics, School of Dentistry, Albert-Ludwigs University of Freiburg, Germany. He was a clinical instructor, Dept. of Prosthodontics, School of Dentistry, National and Kapodistrian University of Athens from 1994–2001. He has published many scientific articles and abstracts, one chapter in a book, and received 2nd prize at the scientific award competition of the EAED in Madrid, Spain, 2008. Dr Pelekanos is in private practice in Athens (AthinaSmile, www.athenasmile.gr) with emphasis on prosthodontics, aesthetic dentistry, pre-prosthetic periodontology and implantology. He is Asst. Professor, Dept. of Prosthodontics, School of Dentistry, National and Kapodistrian University, Athens. Dr Michalis Diomataris received his DDS in 2009 from the University of Athens Dental School, Greece. In 2017 he received his master specialty from the postgraduate programme of Operative Dentistry of the University of Athens. Since 2011, he is supervisor in the education of the undergraduate dental students, in the contemporary principles of aesthetic and restorative dentistry. In 2013 he received the first award of a national competition between the postgraduate students of Operative Dentistry of the national Dental Schools, presenting a case with the topic of “class IV restoration of a maxillary central incisor”. Since 2014, he is a member of the team of Stavros Pelekanos’ Dental Clinic—AthinaSmile, in Athens, Greece, practising in aesthetic and restorative dentistry and prosthodontics. Michalis Papastamos completed his studies in 1983 and ever since he is active on the dental field. Since 1989 he is the owner of the “Dental Aesthetic” dental laboratory, which is specialised in aesthetic restorations. He attends seminars of well established dental technicians and dentists in Greece and abroad, investing in the upgrading of his knowledge and educational level. Moreover, he organises and delivers seminars and demonstrations himself and has participated, in collaboration with Greek and foreign dentists, in complete live dental rehabilitation programmes, being in charge of the dental part. He cooperates with the dental school of the National and Kapodistrian University of Athens, in the field of Prosthodontics.

Adhesive pro- cedures followed (Figs. 16a–f), and final intraoral and extra- oral photographs were captured one week later (Figs. 17a–e). Results Intraoral digital scanning is a perfect alternative clinical procedure compared with the conventional impression technique. The digital planning and mock-up procedure is a powerful communication tool for the dentist, although special skills in using computer software are required. Re- garding the laboratory workflow, most of the analogue pro- cedures require more time (refractory dies, built-up veneers, adjustments), except the staining/glazing (Figs. 18a & b). Although the aesthetic outcome of the feldspathic veneers was subjectively chosen in this case, the analogue workflow is much more demanding. The digital approach, because of the reduced difficulty, speed, complexity and patient dis- comfort, tends to be preferable (Figs. 18a & b). Conclusion Knowledge and application of virtual smile design proce- dures, coupled with innovative dental laboratory technol- ogies, allow dentists to diagnose, plan, create and deliver aesthetically pleasing new dental compositions. Further- more, advances in CAD/CAM technology have catalysed the development of aesthetic veneer restorations with in- dustrially produced materials possessing superior bio- mechanical properties and good aesthetics. cosmetic 1 2018 dentistry 19
