Creating a digital era dental robot

Rayo 3DToothfill aims to improve the lives of billions of people with affordable, high-quality dental health. Their solution provides the best results with comparable costs for the dentist and for the patients. To ensure their solution is usable in different surroundings, it is simple and easy-to use. This is why they take seamless integration with existing equipment seriously.

Rayo 3D-ToothFill Ltd offers a dental robot which revolutionizes creation process of tooth restorative fillings with digital imaging and 3D printed molds. The goal is to bring daily restorative dental care to the digital era and make dental restorations last for a lifetime.

The operation principle of the robot is fascinating: the dentist scans the cavity and designs the 3D restoration utilizing the scanner’s CAD software on the computer screen. On completion, the design is imported from the scanner software into the Rayo 3DToothFill software to manufacture both the mould and the restoration. The process starts by printing the mould, which is then transferred to the Rayo robot that manufactures the restoration by casting filling material layers in the mould. The whole process is completed during a single appointment.

“Etteplan is a big company but at the same time extremely agile through its teams. We were able to add resources and get extra boost for product development when needed.” Kenneth Tarvonen, CEO, Rayo 3D-Toothfill Ltd

Once Rayo 3D-Toothfill Ltd introduced their innovation, Etteplan began creating the product and systematically developed the idea further. The project ranged from hardware and software design to the development of a prototype suitable for clinical trials. One critical area in the product development was the mould design software Rayo 3DToothFill SW: the part to be cast changes every time, which brought its challenges in creating the 3D modeling algorithms. Throughout the project, Etteplan made sure that all the regulations were considered. The requirement definitions were also done by Etteplan.

“Basically, we had a carefully thought-out idea and a filed patent application, while Etteplan had the know-how to turn the idea into a working device. We needed a partner who would be able to handle both robot and software design, and who would also have experience in medical device design. Etteplan was one of the few players who ticked all the boxes,” explains CEO Kenneth Tarvonen.

“At the moment we have a working prototype, another filed patent application, and we are conducting clinical research. This has been an extremely close co-operation model and partnership. Without Etteplan’s support we would not be at this stage.”

In addition to design expertise, Etteplan receives praise of the smooth flow of the project.

“The project was managed very well, and everything proceeded in a disciplined manner. We were impressed by Etteplan’s expertise, continuous development, clear reporting and responsibility,” Tarvonen says.
