The average weight of a dental crown depends on the material and the size of the tooth, but here are typical ranges:
- Single posterior molar crown: approximately 1.2–2.0 grams
- Single anterior crown: approximately 0.5–1.0 grams
Typical weights by material:
- Lithium disilicate (e.g. IPS e.max): around 1.0–1.8 g
- Zirconia: around 0.8–1.6 g
- Porcelain-fused-to-metal (PFM): around 1.5–2.5 g
- Full metal (gold alloy): often 2–4 g, depending on the alloy and the tooth being restored.
3D-printed ceramic-filled resin crowns (such as ceramic-filled dental resins), the cured crown is typically in the 0.8–1.5 g range.
For 3D-printed ceramic-filled resin crowns, an average finished crown (excluding supports and waste) is often around 1.0–1.3 g.
That means 250 g of resin could theoretically produce about 190–250 crowns.
In real-world production, you’ll also have:
- Support structures
- Raft/base
- Resin left in the vat
- Printing losses and occasional failed prints
After accounting for those factors, a practical yield is often closer to 170–220 crowns from a 250 g bottle, depending on your printer, nesting, and support strategy.
For the PioNext Mini using PioNext Ceramic Crown Resin, a realistic estimate is:
- Average finished crown: approximately 1.1–1.3 g of cured resin.
- Theoretical yield from 250 g: about 190–225 crowns.
- Practical yield (including supports, raft, resin left in the vat, and normal printing waste): approximately 170–200 crowns.
If you’re printing multiple crowns together and optimizing support placement, you can get closer to the upper end of that range.
If you’re printing one or two crowns at a time, the extra supports and raft will reduce the yield.
So, for planning purposes, expect around 180–190 crowns per 250 g of PioNext Ceramic Crown Resin under normal laboratory conditions.
If the resin costs R7,000 for 250 g, the resin cost per gram is:
- R7,000 ÷ 250 g = R28.00 per gram
Using different average crown weights:
- Average crown weight Resin cost per crown
- 1.0 g R28.00
- 1.1 g R30.80
- 1.2 g R33.60
- 1.3 g R36.40
- 1.5 g R42.00
If you assume an average crown weight of 1.3 g, then:
- One crown costs approximately R36.40 in resin.
If you also account for supports, failed prints, and resin left in the vat (say an additional 10–20% resin usage), the practical resin cost per crown would be approximately:
- 10% extra: about R40.00 per crown
- 20% extra: about R43.70 per crown
So, a good working estimate is around R40–R44 worth of resin per crown under normal production conditions.
