The recent return of interest to Porcelain Jacket Crowns has been accompanied by the development of improved ceramic systems for their fabrication. One such system, In-Ceram, uses an interesting variation of the aluminous porcelain (Vitadur Alpha). It is important to realise the requirements for tooth preparation so that long lasting restorations may be produced. This article endeavours to present a method for preparation which is both efficient clinically and satisfies the physical requirements for this type of metal-free ceramic procedure.
