I 41 industry news _ Sirona I CAD/CAM 1_2010 _Sirona Dental Systems recently launched a new user-friendly software that has been developed for its inLab system, which is based on Sirona’s patented biogeneric technology. Like fingerprints, no two human teeth are identical and each tooth has its own unique characteristics. A group of researchers led by Prof Albert Mehl (University of Zürich) and Prof Volker Blanz (University of Siegen) found that the shape of natural teeth is based on a person’s genetic make-up. Sirona has harnessed this un- derstanding in its new biogeneric inLab soft- ware, which enables dental technicians to create lifelikereconstructions,evenwhileworkingwith completely damaged occlusal surfaces. On the basis of a single intact tooth, the pro- gramme extrapolates the natural morphology of that tooth to the patient’s damaged tooth structure. “Biogenerics is based exclusively on the patient’s individual dentition status,” re- marked Prof Mehl. “This is a major advantage in terms of clinical reliability. The more individual the occlusion, the better the resulting function- ality.” Currently, all occlusal design approaches are based on limited dental libraries and databases containing data records of various teeth of standard types. Conventional CAD/CAM pro- grammes retrieve a matching tooth from the archive, and then generate a design proposal for the given clinical situation. The user then manu- ally edits and adapts this proposal. This selection is not justified according to any objective prin- ciples. Furthermore, using matching databases can be subjective and time consuming. “Biogenerics will revolutionise occlusal sur- facedesign,”saidBartDoedens,VicePresidentof Dental CAD/CAM Systems. “With a single mouse click, the user will obtain a natural and individu- ally designed restoration that requires hardly any manual adjustment. Such made-to-meas- ure restorations are simpler, quicker, and, above all, more precise than their off-the-rack equiva- lents.” The biogeneric design feature will replace the dental database feature in previous inLab soft- wareversions.Withthenewsoftware,whichcan be used for all single-tooth restorations and three-unit bridges, it will be possible to create crowns, veneers and anatomically sized bridges easily. The user will only require an intact refer- ence tooth of the same type, that is anterior or posterior._ New inLab software with biogeneric capabilities Sirona Dental Systems 3030 47th Avenue,Suite 500 Long Island City,NY 11101 USA Tel.:+1 800 873 7683 E-mail:contact@sirona.com Website:www.sirona.com _contact CAD/CAM
