Filament would have been for a temporary crown, but the machined porcelain eliminates the need for a temporary crown; a nice improvement.

Note that SLS (solid Laser Sintering also is a viable method for dental crown

<p>If the right filament material is available, it seems practical for dentist to 3D print temporary crowns. Multiple images of the tooth to crown could be used for a 3D scan.

Anyone know of development to do this? This probably would take a series of clinical trials to get FDA approval.</p>

Summarize this articles information on crowns and you've answered the question.  Not sure about FDA approval.

Checked with dental office and found out that some dentist in the U.S. are already using the technology in the above link.

You ask about "filament", so I assume you expect fused-filament technologies. These are however not accurate enough, besides being prone to gaps and crevices which are problematic in crowns. The smallest viable nozzle, 0.2 mm, is still too rough for that.

Dental 3D printers need to be very accurate, so the most common technologies used are stereolithography (SLA) and digital light processing (DLP).

Crowns can be made using resin printing. It is possible to use also CNC machining of porcelain, but it's not part of 3D printing.
