Gerard recently attended the Cerec 30 course in Sydney,
held over two (long!) days.
Much of the content related to the various porcelain materials currently used in this digital technology, and the differences in techniques for bonding them to tooth substance. Significant attention was paid to the resin-infused porcelains, such as Enamic, which are unique for their flexibility – a property that can be very beneficial in some circumstances. Other porcelains, such as fused lithium disilicate (e.g. Emax), also attracted attention due to their remarkable compressive strength.
Ultimately, however, a number of the lecturers demonstrated that it is the way in which the porcelains are bonded in place that is largely responsible for their success (in contrast to traditional crowns, which are cemented). Given that Cerec can be used with much less destruction of natural tooth tissue than traditional crowns (but with similar success rates), at Rockingham Dental Centre we believe this additional complexity is well worth the effort. Of course, there are still times when a traditional crown is the correct and appropriate treatment option.
Many of the other lectures contained glimpses into the ‘crystal ball’, looking at what future developments may be made in this technology, particularly the capacity to integrate digital dentistry with implants. This is certainly an area we are keeping our collective eye on, as implants become a larger part of daily dental treatment.
