Biocompatible zirconia
Crowns are constructed from an inner framework - which provides strength and a close marginal fit to prevent food and debris getting under the crown - on top of which porcelain is built up to simulate natural tooth enamel.
Renishaw's inciseTM frameworks are made from zirconia, a very tough, light-coloured ceramic that is highly bio-friendly. This means that not only is the crown or bridge strong and long-lasting, it also avoids the unpleasant allergic reactions and even toxicity that may be associated with metal-based restorations.
No more unsightly black lines
In many cases, patients fitted with dark-coloured metal-based crowns experience unsightly black lines around their gum line as their gums shrink away from metal framework (see image right). inciseTM biocompatible ceramic frameworks avoid this problem!
