Abstract
A dental crown consisting essentially of stabilized zirconia. The dental crown is particularly suited for pedodontic and veterinary applications and most preferably for pedodontic applications. The zirconia crown may be formed by one of several manufacturing processes. The formed crown exterior can be polished and fine polished and can be covered, preferably only partially, with a porcelain glaze to produce an aesthetic outer surface mimicking a natural tooth. Also disclosed is a method for providing and placing a dental crown upon a natural tooth.

A method for restoration of baby teeth of a child patient through use of dental crowns, the method including the steps of:
- preparing a baby tooth in a child patient for receiving a dental crown upon the baby tooth;
- selecting a dental crown to be placed on the baby tooth, the dental crown selected from a kit of pre-fabricated dental crowns, the pre-fabricated dental crowns having various sizes, the dental crowns formed of a monolithic core consisting essentially of stabilized zirconia;
- applying a cement between the prepared baby tooth and the dental crown of said selecting a dental crown step;
- fitting the dental crown with the cement onto the baby tooth of said preparing a baby tooth step;
- said selecting a dental crown step including the dental crowns in the kit of pre-fabricated dental crowns having an open interior chamber bounded by an inner surface;
- said selecting a dental crown step including choosing a dental crown from the kit of pre-fabricated dental crowns with an open interior chamber larger than the baby tooth of said preparing a baby tooth step;
- said selecting a dental crown step including the dental crowns of said kit of pre-fabricated dental crowns having at least one retention feature formed in the inner surface;
- said applying a cement step including the cement passing at least partially into the retention feature, either during said applying a cement step or during said fitting step;
- said selecting a dental crown step including the dental crowns in the kit of pre-fabricated dental crowns having a wall thickness of less than about half a millimeter at a margin thereof, around a circumference of an opening into the open interior of the crown;
- said selecting a dental crown step including at least two related pre-fabricated dental crowns each shaped to fit over posterior baby teeth and each having a similar buccolingual dimension but having differing mesiodistal dimensions, to provide the two related crowns as a standard size crown and a narrower crown;
- determining if posterior baby teeth spacing indicates use of a standard size crown or a narrower crown;
- and
- said selecting a dental crown step including selecting a posterior crown from the at least two related pre-fabricated dental crowns having a more desirable mesiodistal dimension.
