Dental Tribune Middle East & Africa Edition | 4/2016 6 industry Red&White AestheticHarmony ByShofu Beautifil II Enamel and GINGIVA from Shofu are developed as a com- plementarylineextensionofBeauti- fil II to create life-like direct resin res- torations.Aspecialone-pushsyringe ensures controlled dispensing of the smooth and creamy material that is easy to sculpt into fine details and recreate the surface textures seen in naturalteeth&gum. Inclusion specially modified multi- functional organic fillers and nano- fillers impart Beautifil II Enamel and Gingiva with exceptional handling characteristics, longer working time, highabrasion/wearresistance,stable shades, effortless and superior pol- ish with sustained polish retention for lasting aesthetics. Shofu’s pro- prietary S-PRG fillers offer additional fluoride benefits and anti-plaque ef- fectontherestorationsurface. Beautifil II Enamel is available in 4 naturallytranslucentandopalescent shades that facilitate life-like shade reproduction and value adjustment in the final restoration to meet indi- vidualclinicalneeds. Beautifil II GINGIVA is available in 5 natural shade variations of pink to easily mimic patient’s individual gum while restoring areas with re- ceded or missing gums/papilla, cer- vical defects, root caries/erosion, ex- posed PFM margins and abutments to achieve red and white aesthetic harmony.

The study, which was conducted jointlybytheUniversityofMaryland in Baltimore and the University of Freiburg in Germany, aimed to com- paretheabilityofintra-oralscanning systems of different brands to accu- rately scan a single molar abutment tooth in vitro. The analyses included the following six scanners: iTero (Align Technology), 3M True Defini- tion (3M ESPE), PlanScan (Planmeca), CS 3500 (Carestream Dental), TRIOS and CEREC AC Omnicam (Sirona DentalSystems). In order to compare the accuracy of each system, the investigators used an industrial-grade, highly accurate reference scanner to create a digi- tal reference dataset for an acrylic dental model. A single trained, ex- perienced dentist then scanned the acrylicmodelonthreeseparateocca- sions using each of the six intra-oral scanningsystems. Trueness (accuracy) was defined by superimposing the three digital datasets over the reference dataset, with 3-D comparisons then per- formed. Precision (consistency) was defined by superimposing each dataset over the other two datasets obtainedandthenevaluatingfor3-D deviations. Of the 18 datasets analysed, the smallest deviations for the trueness measurements (± standard devia- tion) between the reference dataset and the various intra-oral scanner datasets were obtained from TRIOS (6.9 ± 0.9 µm), followed by CS 3500 (9.8±0.8µm),iTero(9.8±2.5µm),3M True Definition (10.3 ± 0.9 µm), Plan- Scan (30.9 ± 10.8 µm) and CEREC AC Omnicam(45.2±17.1µm). As for precision values, here too 3Shape’s TRIOS was identified as the most accurate (4.5 ± 0.9 µm), fol- lowedby3MTrueDefinition(6.1±1.0 µm), iTero (7.0 ± 1.4 µm), CS 3500 (7.2 ± 1.7 µm), CEREC AC Omnicam (16.2 ± 4.0 µm), and PlanScan (26.4 ± 5.0 µm). “The TRIOS scanning technology, in combination with the wand design, seems to be beneficial for capturing high quality datasets with excellent trueness and precision values,” the investigatorssaid. However,theresultsobtaineddonot provide any information about the quality of a fabricated restoration based on these digital datasets, the researchers stressed. Moreover, in an in vivo design, the outcomes might be different owing to the presence of blood, saliva, and patient move- ments,theyconcluded. The study, titled “Evaluation of the accuracy of six intraoral scanning de- vices: An in-vitro investigation”, was publishedinVolume10,Issue4,ofthe ADAProfessionalProductReview. 3Shape’s intra-oral scanner TRIOS delivered the most accurate results when compared withotherleadingscanningsystemsinarecent study.(Photograph:3Shape)
