| case report From digital planning to the mock-up and final restoration Presentation of a modern work concept on the basis of a veneer fabrication Dr Cyril Gaillard & Jérôme Bellamy, France Introduction The solution The demand for cosmetic treatments is also increas- ing in dental practices. The Internet provides patients with virtually limitless access to a wealth of information on this topic. And with it comes an increase in expec- tations. This can pose a conundrum to the dentist: pa- tients want to be promised the desired results, yet, they should not be given undue expectations in the run-up to the treatment. The challenge One of the challenges in day-to-day dentistry is the fact that the mock-up presented to the patient is produced from a wax-up, and is often not consistent with the final outcome of the treatment (e.g. ceramic veneers). Sev- eral research studies have been initiated to overcome this problem. The SKYN concept is a result of this research. The SKYN concept is based on a unique approach: it uses natural tooth shapes to create a mock-up directly in the patient’s mouth. A wax-up is created on the basis of tooth shapes that reflect the anatomy and morphology of natural teeth in terms of height, width, curvature and surface texture. The predictability of the result is ensured by using CAD/CAM technology to scan the mock-up, make adjust- ments in the oral cavity, and then mill the veneers to achieve lifelike results. The reproducibility of the mock-up and the accuracy of the result arise from, among others, the perfor- mance of the CAD/CAM system, allowing the expectations of the patient to be met both promptly and effectively. CAD/CAM technologies have brought about a revo- lution in dentistry. They enable the efficient manufacture of customised ceramic veneers with high accuracy and within a short period of time. a b Figs. 1a & b: Initial situation.
