CYRTINA - Les limites à la Céramique. Exploration des implications des propriétés des matériaux. (en néerlandais)

Full ceramic crowns and bridges were introduced in the 1980s, but the ceramic materials used nowadays for this type of restoration differ completely in terms of composition and structure. The changes have taken place so quickly that clinical research and scientific evidence of durability have often been neglected. Dentistry has already learned her lessons, being confronted with chipping and fractures. For example, although the effect of the high hardness of zirconia on the abrasion of antagonists has now been studied extensively, we still do not know anything about the effect of the increased load exerted  on the remaining teeth. The drive of the industry to provide an ever higher translucency of zirconia leads to concessions in initial and 5 year-strength, of which the clinical impact remains uncertain. In the lecture, the boundaries of ceramic restorations are explored and intelligent clinical solutions and procedures for their durable application in dental practice proposed.

Seminar by Prof. dr.ir. Jef van der Zel

Prof.dr.ir. Jef van der Zel. From 1977 to 2007, Jef van der Zel was involved in research into alloys and metal ceramics, press and sinter ceramics at Elephant-Dentsply. He is seen as one of the pioneers of dental CAD/CAM, a. o. in the field of CAD software, desktop scanning, virtual articulation and guided implant planning. In 2004 he became a special professor of Computerized Dentistry at the University of Amsterdam. Research focused on histo-anatomic ceramic crowns and bridges with CAD/CAM ("Primero").
