3D Printing in Dentistry
Lovish Melanta and Joasia Sendek
Bio statistics April 11, 2014
3D printing is the process for making a physical object from a three-dimensional digital model, typically by laying down many successive thin layers of a material.
3D printing allows for the cheap, easy creation of complex structures.

What is 3D Printing?
Introduction
3D printing takes the efficiencies of digital design to the production stage. By combining oral scanning, CAD/CAM design and 3D printing, dental labs can accurately and rapidly produce crowns, bridges, stone models and a range of orthodontic appliances.

With a 3D printer doing the hard work, dental labs eliminate the bottleneck of manual modeling and let the business grow.
Summary
3D printing has proven to be rather useful in dentistry. Despite some of the problems that 3D has shown, the process eliminates hand-made mistakes through the original molding procedures, creates detailed models down to the smallest detail, and increases production quantity in a shorter period of time. Although using dental molds will not be eliminated anytime soon, 3D printing will definitely increase in the future for dentistry.

Instead of making a mold and sending it to a lab for scanning, dentists are now using a small camera to scan the misshapen teeth directly. The digitized scan is then sent to an on-site milling machine that carves the crown from a block of porcelain – in about an hour. After about 15 minutes of preparation the crown is ready to be implanted.

The system is provided by Sirona. The company is one of the first to use computer-aided design (CAD) and manufacturing (CAM)

Dentists are now taking out the mold and the middleman.

It's Not All Good - Limitations

The carving process is not sufficiently agile to faithfully reproduce the intricate variations of a real tooth. Therefore, replacements for the very visible front teeth will remain the job of mold-based machines.
The scanners can’t scan beneath the gumline, any tooth damage occurring below the gumline would necessitate a mold.
Usage In Real Life
An 83-year-old woman in Belgium is now the proud owner of what could be possibly the coolest lower jaw in history: a 3D printed titanium mandible replacement

The final jaw replacement made from titanium weighs just a tiny bit more than an actual jaw and will allow the patient to eat and speak as normal once she’s healed.
