Chinese dental laboratory turns to EnvisionTEC printers and materials for aligner production

Stay up to date with everything that is happening in the wonderful world of AM via our LinkedIn community.

Hanyang Technology, located in Baoding, Hebei Province China was founded in July 2017 by CEO Sasa Jia and Technical Director Vivian Wang. Hanyang’s core products are orthodontic at present, predominantly the production of tooth aligners. The business also engages in the application of medical and 3D printing technology research and recently registered a new transparent dental appliance brand MYDEMAK. For their high-end 3D printing needs, the Hanyang team turned to EnvisionTEC.

The customized transparent tooth appliances that Hanyang produce need to be incredibly accurate and closely aligned with the tooth crown of the patient. Failure to achieve this results in incorrect orthodontic force and potential damage to teeth. From their experience, replacing gypsum tooth models with the 3D scanning of tooth impressions and 3D printing provides a far more accurate result for the patient.

“EnvisionTEC is widely recognized in dentistry, and its DLP technology is superior. Their materials and equipment have great advantages compared with other brands”

Vivian Wang, Technical Director, Hanyang Technology.

Finding the best 3DP option
Hanyang’s management team were aware of EnvisionTEC’s brand as early as 2015. Through their network they received multiple reports of EnvisionTEC’s DLP technology and its premium 3D printing capabilities in areas such as hearing aids, jewelry and dentistry.

In early 2017, before the launch of Hanyang, the team knew they needed to investigate the best options in terms of 3D printers, scanners and materials. After discussing their options with contacts within the industry and closely examining their options, including a number of brands, and even a homemade SLA machine, they settled on two of EnvisionTEC’s 3D printers, a Vector 3SP and a DDDP (Digital Desktop Dental Printer).

This decision was made based upon EnvisionTEC’s expertise in the field of dentistry and orthodontics, the recognition within the market, the exceptional accuracy of the printers and the surface quality of the models.

“Digital dental solutions will certainly be the trend in the future. More and more hospitals and clinics will accept 3D printers, dental crowns, implant guides and orthodontics produced by 3D printing.”

An E-model to follow
Hanyang can process digital files from other dental labs or digitized from impressions on its in house 3Shape scanner. The team can then use 3Shape or Maestro 3D software to modify these and print accurate models of the teeth in the EnvisionTEC E-Model material. A vacuum mechanism is then used to form the invisible orthodontic appliances over the model.

Hanyang’s digital solution provides it with the competitive edge over manufacturers who are still reliant on traditional gypsum models. The 3Shape scanner and EnvisionTEC printer provide much improved accuracy of the tooth models, this in turn results in better fitting aligners for its customers.
