Sino Ortho Preformed Crowns are manufactured from
surgical-grade stainless steel, expanded and shaped via multi-stage drawing to avoid edge cracking and boost structural integrity. Each crown is
anatomically contoured to closely match tooth morphology, ensuring a snug fit with minimal adjustment. The
sand-blasted inner surface enhances bonding reliability, while
rounded, polished margins reduce irritation and improve patient comfort. Available in
48 size variants to accommodate different tooth positions and dimensions, our crowns deliver dependable clinical performance and ease of use.
