Technological innovation has always been a significant part of the dental profession. From the advent of X-rays to the introduction of digital imaging, each breakthrough has brought profound improvements to patient care. Now, the rise of 3D printing marks another milestone, particularly its use in orthodontics. Currently transforming dental practices, 3D printing has quickly become a key tool in many aspects of dentistry. For orthodontists, this technology opens up exciting possibilities, enabling the creation of precise, customized appliances while streamlining workflows and reducing materials waste. As Dr. Normand Bach says, “3D printing is not just a tool—it’s a game-changer for our profession.” In this article, we explore the current applications, benefits, challenges, and the promising future of the use of 3D printing in orthodontics. The Rise of 3D Printing in Orthodontics Orthodontics is a field where precision is paramount. Even the smallest misalignment in an appliance can lead to discomfort for patients, delays in treatment progress and can also increase the risk of tooth decay. This is where 3D printing shines. At its core, the technology relies on additive manufacturing—a process that builds three-dimensional objects layer by layer, from materials such as plastics and metal powders. With advancements in computer-aided design and manufacturing (CAD/CAM), orthodontists can now design appliances and fabricate them in their own offices with remarkable accuracy. “The precision and customization we can achieve with 3D printing were unimaginable just a decade ago,” explains Dr. Bach. “This technology allows us to address the unique needs of each patient with unmatched accuracy.” Initially, 3D printing was used for creating accurate dental models. However, its applications have expanded to include the fabrication of orthodontic appliances like lingual retainers, palatal expanders and transpalatal arches. By combining digital scans of a patient’s teeth with advanced orthodontic software, practitioners can Dr. Normand Bach is an associate professor in orthodontics at the faculty of dental medicine at the University of Montreal. 26 | 2025 | Issue 2
