A dental crown is primarily made by CNC Milling. CNC milling removes material from a fixed blank with a rotating cutter moving on several axes, carving complex features to tight tolerance. Below is the full route to make a dental crown, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.
Step by step
How a dental crown is made
The usual route, raw material to finished part. The amber step is where the dental crown gets its basic shape.
Stock
Start from bar, plate or billet sized for the dental crown.
CNC Milling (roughing)
Rough out the main shape, leaving stock on the critical surfaces.
Tooling None Tolerance ±0.125mm, to ±0.025mm Lead 1 to 10 days
Finish machining
Take the finishing passes that bring the dental crown to tolerance.
Tooling None Tolerance ±0.125mm, to ±0.025mm Lead 1 to 10 days
Holes and features
Drill, ream and tap, and where needed broach splines or cut gear teeth.
Tooling None Tolerance ±0.05 to 0.2mm Lead hours to days
Heat treatment
Harden and temper if the dental crown must resist wear or load, then finish-grind.
Tooling n/a Tolerance can distort Lead days
Grinding
Where the dental crown has bearing or sealing surfaces, grind them to the tightest tolerance and finish.
Tooling Low (wheel) Tolerance ±0.002 to 0.02mm Lead days
Surface finish
Anodise, plate or coat for wear and corrosion resistance.
Tooling Low Tolerance adds microns Lead days
Inspection
Measure the dental crown against the drawing, on a CMM for close work.

Cost
What a dental crown should cost
Prismatic parts; priced by machine time and setups. Fewer setups and looser tolerance drop the price fast.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for a dental crown at your volume, in your currency, are in the dossier.

What does a dental crown cost?
It depends on size, tolerance and volume. As a rough ballpark it starts around $230 to 310 per part at 1 off and falls with quantity. The dossier gives should-cost at your exact volume and currency. A model estimate, not a quote.
What material is a dental crown made from?
Common choices are Ti-6Al-4V ELI (ASTM F136); CP titanium grade 4 (F67); Cobalt-chrome (F75 / F799); 316LVM stainless (F138).
What is the main process for a dental crown?
CNC Milling. Precision prototypes and low to medium-volume parts of almost any shape and material.
