Conclusion According to the manufacturer, all colour components in the IPS Style contain oxyapatite crystals in differ- ent quantities. For this reason, the opaquer is also an essential part of thecolourconceptoftherestoration. In the end result, the metal-ceramic IPS Style Ceram impressed us in particular through its natural trans- lucency and the depth of light trans- mission. IPS Style helps the dental technician to achieve highly esthetic restorations efficiently with easy material handling and a low level of shrinkage during firing. There are no particular specifications to observe in terms of design on the metal. The dental restoration is so vibrant and life-like that no one would think it hadametalsubstructure. One specific advantage of the visual properties of IPS Style is that the outline of the framework is not seen through the ceramic as sharp edges. Due to the high degree of reflection and wide range of light-scattering, much less Deep Dentin material is required for concealing in compari- son to conventional metal-ceramic materials. Less space is required for the ceramic. Without the problem “framework outline”, less experi- enced ceramic technicians are also able to use the IPS Style Ceram layer- ingceramic. Dental technical assessment ofthenewveneeringceramic How the IPS Style Ceram is for us dental technicians: We are able to fully concentrate on the layering technique and build-up process. The IPS Style materials are very easy to work with: finely granulated and homogenous, with a pleasant and individually adjustable consistency. They are stable. Sharp edges and detailed structures can be easily cre- ated. The layers adhere well to one another. Inaddition,averyimportantpointis the working efficiency. The ceramic has a low degree of shrinkage, only slight over-contouring is required. The built-up morphology design is maintained. Our assessment, which also applies to this patient case: When using the IPS Style materials, Dr.AdrianBacila, Romania FlorinStoboran graduatedfrom the DentalTechnician SchoolinOradea, Romania,in1994.He continuedhisstudies inceramicsand specializedinfixedprosthetics,esthetics andimplantology. the ceramist can let his artistic abili- tiesandskillsrunfree. We would like to thank Dr. Adrian Bacila for the good working coopera- tion. ◊PageB2
