Zirconia Crowns

Zirconia Crowns

This category covers the preformed zirconia crowns used to fully restore a primary tooth after decay or pulp therapy. Because each crown is moulded for one tooth position, it is selected to match the tooth rather than trimmed to fit, then cemented in a single appointment. Shop the range to keep a tooth-coloured option on the tray for every case in the paedodontics setup.

What you can buy here

The range covers crowns by tooth, plus the packs they come in:

• Molar crowns — separate shells for the upper and lower, left and right first and second primary molars.
• Anterior crowns — upper central incisor and lower canine forms for the front teeth.
• Kits and refills — a graded kit to find the size chairside, and single-position refills to restock the sizes fitted most.

Everything here is a tooth-coloured full crown; it sits alongside the metal and composite options in the wider pedo crowns range.

Why a zirconia crown is worth it

For a tooth that shows when a child smiles, a zirconia crown earns its place:

• Tooth-coloured — solid white ceramic instead of a silver cap, so the restoration blends in.
• Full coverage — the whole crown is protected, carrying a heavily broken or pulpotomised tooth to natural exfoliation.
• Smooth and biocompatible — the glazed surface resists plaque and is gentle on the gum.

A metal crown still wins on sheer durability for a hidden back molar, but zirconia is the pick wherever appearance matters. It pairs on the tray with the stainless steel crown for the posterior teeth it does not suit.

How it fits your treatment

A zirconia crown is placed differently from a bendable metal crown, because the ceramic is rigid:

• Reduce — take more tooth than for a metal crown, so the crown seats passively without force.
• Try in — fit the numbered crown dry to confirm the size, then control moisture and bleeding.
• Cement — lute with a resin or glass-ionomer cement; there is no crimping or contouring.

Preparation, try-in, and cementation are completed in one visit. Where a preform will not suit a front tooth, a strip crown rebuilds it directly with composite instead.

Why is a zirconia crown fitted differently from a metal crown?

Because zirconia is rigid and cannot be crimped or bent to grip the tooth. A metal crown can be squeezed onto a slightly under-prepared tooth, but a zirconia shell has to drop on passively, so the tooth is reduced more and the preparation must be smooth and undercut-free. The fit comes from the prep, not from adjusting the crown.

Is a zirconia crown suitable for a front baby tooth?

Yes, a zirconia crown suits a front baby tooth when enough tooth remains to hold a preformed shell and appearance is a priority. It restores full coverage in a natural white shade. If the tooth is too broken or irregular for any preform, a composite strip crown built directly on the tooth is the better option.

When is a metal crown the better choice?

A metal crown is better on a back primary molar that is not visible, where durability and speed matter more than looks. A stainless steel crown needs less tooth reduction, tolerates a slightly imperfect preparation, and can be crimped to grip. Zirconia is preferred on teeth that show when the child talks or smiles.

Kit or refills — which should a clinic order?

A kit suits a clinic starting out, or one that wants the full size range for a tooth on hand to find the fit chairside. Single-position refills suit restocking once the commonly placed sizes are known, so only the sizes that move are reordered. Many clinics keep a kit plus refills of the common molar sizes.

Will the crown stay on until the tooth is shed?

A correctly prepared and cemented zirconia crown is intended to last the life of the primary tooth. The monolithic ceramic resists wear and fracture, and full coverage protects the whole tooth. Longevity depends on a passive fit, a dry field at cementation, and sound cement, not on the crown material alone.
