Directly printed clear aligners

A promising development in the field of orthodontic therapy that has the potential to revolutionize the production of clear aligners.

The current process of aligner production involves taking an impression of the patient’s teeth and creating a physical model of the jaw. This model is then used to create a thermoformed aligner, which is a clear plastic tray that fits over the teeth and gradually moves them into the desired position. However, this process can be time-consuming and wasteful, as it requires the use of materials that can be difficult to recycle.

To address these issues, we have been developing a 3D printer that can directly print clear aligners from a digital model of the patient’s teeth. This process eliminates the need for a physical model and reduces waste, as it uses only the amount of material needed to create the aligner. The printer can also produce aligners more quickly and accurately than the traditional thermoforming process.

The development of 3D printer involved extensive research, including the analysis of existing technology and materials, the acquisition of necessary equipment and software, and the experimental testing of technological concepts.

The prototype printer and printed aligners are currently undergoing further clinical testing.
