Abstract: Original researchpreformed pediatric full-coverage restorations for primary teeth that offer the flexibility and snug fit of the preformed metal crowns, and the esthetics of preformed zirconia crowns.8,9 The clinical data in the literature for this crown are still nascent and evolving.The current paper studied the clinical performance of the BioFlx crown. IntroductIonThe demand for esthetics in primary teeth now encompasses not only anterior teeth but also posterior teeth.Unesthetic restorations are frequently refused by parents. 1 Preformed indirect zirconia fullcoverage restorations for primary teeth were introduced in the year 2010 to fulfill this clinical demand. 2 These full-coverage restorations offer natural esthetics along with long-term color stability, strength, biocompatibility, and durability.3 They are also autoclavable.4 The yttrium-stabilized zirconium-based preformed zirconia crowns manufactured by the injection molding technique or milling technique have mechanical properties similar to a metal crown.Adjustment through trimming, crimping, or contouring is therefore not possible.This lack of flexibility, therefore, dictates greater tooth reduction for a passive fit. 5 The preformed zirconia crowns also require aggressive subgingival tooth preparation, which dissuades the clinician from placing them in young children.The ideal full-coverage restoration for primary teeth should retain the advantages of the preformed metal crown (stainless steel crowns).These include conservative tooth preparation and their ability to be trimmed, crimped, and contoured, resulting in a snap clinical fit.But an ideal full-coverage restoration should also be esthetic to fulfill the esthetic demands of the parent and child.6 The indirect performed "BioFlx" full-coverage restorations (Kids-e-Dental, LLP, Mumbai, India) are a new generation of crowns fabricated from a biocompatible high-strength radiopaque polymerized resin already existing in the human healthcare field.7 They are monochromatic, tooth-colored, and free from A-glycidyl methacrylate.flexible, long-lasting, self-adapting, and life-like
