What teeth crown, as the scientific expression, means is the operation of crowning the teeth with porcelain material for aesthetic purposes. However, the porcelain should be supported because it is fragile against the intraoral strengths. In the case where zirconium based material is used instead of metal support or where the dental prosthetis is completely produced with zirconium, it is referred to several names such as zirconium, zircon, zirconia, zirconium coat, zirconium tooth, zircon tooth, zirconium crown etc.
It is one of the main applications of aesthetic dentistry. Composite laminate (bonding, composite lamine, composite fill) are aesthetic restorations made of composite material on the tooth surfaces in order to change the shape or colour of the tooth, enlarge it or fix it for aesthetic purposes without damaging the teeth.
