Prefabricated Stainless Steel Crowns: Sizes, Tooth Codes and How to Order

A prefabricated stainless steel crown (SSC) is a preformed metal crown that is fitted and cemented over a prepared tooth, most often a primary molar in a child. Chase Dental Supply carries the full MARK3 primary molar line: first and second primary molars, all four quadrants, sizes 2 through 7, five crowns per box.

This guide explains how MARK3 labels its crowns, how the codes map to Universal and FDI tooth numbers, and how to keep a stock that never leaves you short a size mid-appointment.

Key Takeaways

• Chase stocks 48 MARK3 primary molar SSCs: 2 teeth (D and E) times 4 quadrants times 6 sizes (2 through 7).
• Every box holds 5 crowns of one tooth, quadrant and size, with SKUs such as 100-DUR5.
• MARK3 describes the crowns as pre-trimmed and pre-crimped, made in the U.S.A. from high quality stainless steel.
• MARK3 uses per-quadrant letters (D, E), not Universal letters, so lower left second primary molar (Universal K) is ordered as E-LL.
• Pick the size by try-in, and reorder from a usage log rather than by guesswork.

What Is a Prefabricated Stainless Steel Crown?

A prefabricated stainless steel crown is a factory formed crown shell, made in a range of sizes for each tooth, that the clinician selects, adjusts if needed and cements chairside. No lab step or impression is needed.

SSCs are a long standing restoration in pediatric dentistry. They are commonly used on primary molars with extensive or multi-surface decay, after pulp therapy, and on teeth with developmental defects. MARK3 states its crowns offer superior longevity compared to multi-surface amalgam fillings and have proven clinical use for short or long term pediatric use.

What Types of Prefabricated Stainless Steel Crowns Does MARK3 Offer?

The MARK3 line at Chase covers the two primary molars in every quadrant. Each crown type is defined by tooth, arch and side, and then by size.

• First primary molar (D): upper right, upper left, lower right and lower left, sizes 2 to 7.
• Second primary molar (E): upper right, upper left, lower right and lower left, sizes 2 to 7.

Upper and lower crowns are shaped differently, and so are rights and lefts, which is why each quadrant has its own box. MARK3 lists the crowns as pre-trimmed and pre-crimped to speed placement, and says they accurately duplicate anatomy for better fit.

How Do You Read a MARK3 Crown Code?

Read the code left to right: tooth letter, quadrant, size. The SKU uses the same order with a 100 prefix.

• D or E: D is the first primary molar and E is the second primary molar. This follows the per-quadrant lettering (A central incisor through E second molar) used on many pediatric products.
• UR, UL, LR, LL: upper right, upper left, lower right, lower left, from the patient’s point of view.
• 2 to 7: the crown size. With most SSC systems a higher number is a larger crown; confirm on the box when switching brands.
• 5/bx: five identical crowns per box.

If your charting uses Universal letters (A to T) or FDI numbers, use the crosswalk in the table below so the front desk orders the right quadrant.

How Do You Choose the Right Crown Size?

Choose the size by try-in on the prepared tooth. The right crown seats over the tooth with a snug, positive fit, covers the margins and restores the contact without forcing.

• Start with an estimate. Many clinicians gauge the mesiodistal space, or start from the size used on the opposite side, then try that size first.
• Go down if it rocks or spins. A loose crown usually means the next smaller size.
• Go up if it will not seat. If it binds before reaching the margins, try the next larger size.
• Check the bite and margins before cementing, and follow the cement manufacturer’s instructions for use.

Good isolation makes try-in and cementation easier; our Dri-Angles plain vs silver guide covers one simple option. Crowns that were tried in but not used should be handled under your office’s infection control protocol before returning to stock.

Which One Should You Choose? Stocking by Practice Type

Stock depth depends on how many crowns you place each month.

• Pediatric practice: keep every D and E code in all six sizes, and set a reorder point for each box.
• General practice that sees children: start with a full size run for the teeth you crown most, then fill gaps from your log.
• School based and mobile programs: pack a complete 48 box kit per unit so a missing size never ends a visit. See our TPC portable dental systems guide for the equipment side.
• Dental schools: stock full runs per clinic so students can practice the try-in sequence.

Restocking tips

• Log the code (for example D-UR-5) each time a box is opened.
• Order by SKU (100-DUR5 style) to avoid quadrant mix-ups.
• Keep one sealed box of each size as a buffer.

Frequently Asked Questions

What is a prefabricated stainless steel crown used for?

A prefabricated stainless steel crown is a preformed metal crown cemented over a prepared tooth, most often a primary molar. It is commonly used for primary molars with extensive or multi-surface decay, after pulp therapy, or with developmental defects.

What do D and E mean on MARK3 stainless steel crowns?

D is the first primary molar and E is the second primary molar. The letters follow per-quadrant lettering, so the quadrant code (UR, UL, LR or LL) tells you which side and arch.

What sizes do MARK3 stainless steel crowns come in?

Chase Dental Supply carries MARK3 primary molar crowns in sizes 2, 3, 4, 5, 6 and 7 for each of the eight tooth and quadrant combinations. That makes 48 different boxes, each holding 5 crowns.

How do you pick the right stainless steel crown size?

Estimate the size from the space or the opposite side, then try it in on the prepared tooth. If it is loose, try a smaller size; if it will not seat, try a larger size. Check margins and occlusion before cementing.

Are MARK3 stainless steel crowns pre-crimped?

Yes. MARK3 describes its primary molar crowns as pre-trimmed and pre-crimped for fast and easy placement. Any further adjustment is a clinical decision based on the individual tooth.

A well organized prefabricated stainless steel crown kit saves chair time and keeps pediatric appointments on schedule. Chase Dental Supply carries the full MARK3 primary molar range alongside our cosmetics and restoratives supplies. Need a full kit quote? Email sales@chasedentalsupply.com.
