Clear Orthodontic Aligners Created with 3D Printing

3D printing is the process of using computer-aided design (CAD) to build a three-dimensional object. Successive layers of material are added to achieve the object being created. While this technology has initially been used by the manufacturing and metalworking industries, 3D printing is now being adopted by more technologies to speed up the processes involved. In fact, it has revolutionized the way the dental industry works as it is applied in several applications, including the creation of orthodontic aligners.

3D printing uses the technologies of digital light processing (DLP) and stereolithography (SLA) for the most accurate results. The use of 3D printing in dentistry has resulted in significant improvements, which is the reason why more dentists in London are using this technology in making their treatments and procedures more streamlined.

The creation of clear aligners using 3D printing starts with scanning the teeth and then using CAD software to generate a 3D model. One method involves printing the teeth as is by using a plastic sheet to form a vacuum over the model. On the other hand, the patient’s teeth can also be used to model the aligner which would then need to be printed using a special resin material.

What makes 3D printing beneficial to the dental industry? The most significant advantage this technology brings is speed. A full batch of clear aligners can be produced in just a few hours. Also, it will be easier to customize each product it is created using the highly accurate scans of the patient’s teeth.
