About crown forms
Preformed provisional crowns, also called matrices, are tooth-shaped shells of plastic, cellulose acetate or metal. They come in a range of tooth sizes and are picked for a particular tooth anatomy. A shell is commonly relined with acrylic resin for a closer fit before it is cemented, and the plastic and metal shells can also be cemented straight onto the prepared tooth. The FDA calls this a preformed crown, a Class I device of plastic or metal, affixed temporarily to a tooth after the natural crown is removed or broken, and used as a working restoration until a permanent crown is made (21 CFR 872.3330).
Provisional crowns are either prefabricated or custom made. The shelf holds the prefabricated shells, as singles and as kits of several sizes.
What to look at when choosing a crown form
Size and shape: the forms are numbered by size, and the shelf carries anterior and molar shapes. Temporary materials have run from acrylics and premade crown forms to bis-acryl materials and computer-made restorations.
What the provisional has to do: cover exposed dentine, prevent unwanted tooth movement, maintain function, allow oral hygiene, prevent gingival overgrowth and give an adequate interim appearance.
