In this way, by using an efficient layering technique, I can quickly and eas- ily obtain an aesthetic result. I am impressed by the stabil- ity characteristics of the ceram- ics. This material property is an advantage especially in the case of larger restorations. VITA VMK Master offers a comprehensive assortment for individualisation. In this case, however, because a standard so- lution was requested, I kept to justafewdifferentmaterials,and modelled only the mamelons. I built up the incisal edge and the approximal areas by applying ENAMEL (EN1), and OPAL TRANSLUCENT (OT1) (fig. 3). The restoration was fired at 930°C, the approximal and palatal contacts adjusted, the lat- ter in the articulator with lateral and protrusion movements un- der canine guidance before the finishing of the restoration. I am very impressed by the very low degree of shrinkage, which I will be pleased to take into account when layering in fu- ture. A generous applica- tionofporcelainsattheap- proximal points in order to compensate for shrinkage is not necessary to this ex- tent, as I am accustomed to doing with other ceramics. The final glaze firing achievesashadebrilliancy which awakens the tooth to life. There is a natural harmony between opales- cent and translucent re- gions. As with every ce- ramic veneer, the actual success of the restoration can only be seen when the restoration is seated in the pa- tient‘s mouth. Only then is it pos- sible to assess whether the crowns–asdesiredbythepatient – are harmoniously matched to thepatient‘soralsituation.Inour case, patient, dentist and dental technician alike were satisfied with the restoration (fig. 4). Conclusion Our aim is to provide an at- tractive solution with natural aesthetics in the VMK technique, even in cases which initially do not look very promising. If den- tist and / or patient insist on a metalceramicinsteadofafullce- ramic highend solution, we can offer good, competitive results using our CAD/CAM system and VITAVMKMaster,whichisbased on a combination of state-of-the- art equipment and highquality materials. Thanks to the use of a ceramic which is simple to process, pleasant to work with, and has a wide processing inter- val and accurate shade repro- duction, which, in combination with the VITA Linearguide, en- ables the fabrication of crowns with natural aesthetics, time- consumingadjustmentsandcor- rections are usually unneces- sary.
