Science and technology in the present era have become the most important partners, which has a direct benefit on medical industry technology. People all around the globe have been always benefitted by this combination. We have enjoyed the results of the latest developments in medical science, whether it is minimally invasive techniques or ability to create newer bio-campatible materials . At the end of the day , we save time, discomfort and are offered the promise of better health .

In recent times, the world of dentistry has been blessed with the advent of 3D printing technology. 3D technology started its role in dentistry from 1980s and 1990s. Such printers would provide suitable dental parts according to the particular dental orientation of patients as well according to the needs.

What is 3D printing?

3D printing also known as additive manufacturing is used to make 3 Dimensional objects in which layers of objects are formed under computer control for the making of an object. The shape of the object can be any geometric shape which would be produced using digital model data from a 3D model or another electronic data source like an additive manufacturing file.

How 3D technology works in dentistry?

The dental industry is an early mover and has shown greatest use of the 3D technology. 3D systems, Stratasys, Envisiontec, Concept Laser and Renishaw are giant corporations3 that offer 3D printing solutions to meet the needs of dentistry.

Coming to the point, a very simple explanation about the working of 3D technology in dentistry is that, the simple robotic devices are guided by computer aided design software which allows objects and assemblies to be created in a virtual environment. 3D printing uses computer aided design software and computer aided manufacturing to facilitate the use of materials such as metal casting alloys that are creatively and aesthetically used to make designs. The process is similar for all the patients. The 3D printing allows one time fabrication of complex structures in various materials with properties that are highly desirable in dental applications.

 

Applications of the process

 

  • Three D printing detailed replicas of patients jaws which allows dentists and surgeons to carefully study anatomy or plan a surgery even before the surgery is done.
  • The 3D printers provide precise virtual model of the tooth giving detailed idea about the implant position and the dental arch.
  • The scan data of the tooth along with the computer aided design can be used to make/print crown or bridge copings, implant abutments and bridge structures.
  • Invisible braces and computer guided dental implant surgey is also possible with 3D printing
  • In the future many dental labs would adapt to manufacture artificial all types of teeth including ceramic 3d printing.
