With the new developments in Vibratory Deburring Machine, a company has been able to build one of these machines. But instead of this printer being able to print a chair it can print a replica of human bones.

In recent years technology companies have been working hard trying to

build printers that can print in 3-D. These printers essentially would

be given raw materials like wood or metal and then could be programmed

to print a chair. It’s a faster and more precise way to mass produce

products and if refined enough the process could even be more cost

efficient than current measures.

And now with the new developments

in this 3-D printing technology, a company has been able to build one

of these machines. But instead of this printer being able to print a

chair it can print a replica of human bones. These of course are not

actual bones, but they have the look, feel and characteristics of actual

bones. And now that this has been developed experts believe that this

could be the future in crown technology. Many experts believe that this

will even be the logical next step up from the current standard of

dental crowns which is the CEREC same day crown.

The printer was

developed by Washington State University and represents a whole new way

of looking at dental prosthesis. According to the researchers, the

material that the printer uses can actually be paired with real human

bone in the prosthetic. And if this is done correctly the printer

material can function as an infrastructure for the real bone, allowing

the real bone to grow and actually create new bones for the teeth. And

this material will eventually dissolve after real bones take its place,

which so far in the research has caused no side effects to patients.

So far results on tests with rabbits and rats in laboratories have

proved promising. The authors claim they have had successful trials of

the bone like material on rats and rabbits. WSU’s Susmita Bose, a

co-author of the study and a professor at the School of Mechanical and

Materials Engineering says that she believes doctors and dentists may be

able to order custom made replacement bone tissue in a matter of only a

few years.

"If a doctor has a CT scan of a defect, we can convert

it to a CAD file and make the scaffold according to the defect," Bose

says. CAD stands for computer aided design, which is what is already

currently used to aid in the creation of CEREC crowns. The CAD system

uses a computer to take digital pictures of the mouth and map out the

locations and shapes of teeth in the mouth in order to make custom fit

crowns and dental prostheses.

The technology comes as part of a

joint effort between several different fields of study like chemistry,

biology and engineering. The researchers involved first spent a year

optimizing the previous technology in 3-D printing which could print

metal. Using the metal printer as a guide, they could then optimize the

technology to print the new bone-like material.

In the studies the

researchers found that the fake bone material had already supported the

growth of new bone material in a matter of only a week. We hope that

this new tehnology can get out on the market that fast too! This new way

of doing crowns could be revolutionary to the field of dental medicine. This could allow dentists like Dr. Wells to not only create a beautiful looking smile for their patients, but also help them make that smile out of their own natural teeth.
