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; passively 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 aperture formed in the inner surface; said applying a cement step including the cement passing at least partially into the retention aperture, either during said applying a cement step or during said passively 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.
