Pre-veneered stainless steel crowns resolve some of the problems associated with stainless steel crowns, open faced stainless steel crowns, and composite strip crowns. They were introduced in the mid 1990’s. They are aesthetic, placement and cementation are not significantly affected by hemorrhage and saliva and can be placed in a single appointment. The stainless steel crown is covered on its buccal or facial surface with a tooth colored coating of polyester/epoxy hybrid composition.
A clinical disadvantage is they are relatively inflexible as the resin facing is brittle and tends to fracture when subjected to heavy forces or crimping. Because only the lingual portion of the crown can be adjusted (crimped), significant removal of tooth structure must be performed to fit the tooth to the crown rather than the crown to the tooth. There is limited shade choice. They are more expensive to purchase than stainless steel crowns and strip crown forms (approximately $18 vs. $6) yet less expensive than zirconia crowns ($18 vs. $25).
Pre-veneered stainless steel crowns are available from various manufacturers (Kinder Krowns, Mayclin Dental Studios, Minneapolis, MN; Dura Crowns, Space Mainttiners Laboratory, Van Nuys, CA; NuSmile Primary Crowns, Houston, TX; Cheng Crowns, Peter Cheng Orthodontic Laboratories, Philadelphia, PA).
