1. Digital scanning
The process begins with digital scanning, where the patient’s oral anatomy is captured in 3D. This is typically done using intraoral scanners, which can create highly detailed digital impressions of the patient’s teeth, gums and surrounding structures.
2. Digital models
The digital impressions obtained from the scanning process are converted into digital 3D models. These models are virtual representations of the patient’s oral anatomy, created using specialised computer-aided design (CAD) software.
3. Printing setup
Once the digital models are prepared, they are sent to a dental 3D printer. Before printing, the operator chooses the appropriate printing material, settings and design specifications to ensure the final dental appliance meets the patient’s needs.
4. Printing
The 3D printer follows the digital model’s instructions to build the dental appliance layer by layer. It uses the chosen printing material, which is often a light-cured resin and a curing light source to solidify and bond the material. This additive manufacturing process is precise and allows for highly customised and patient-specific dental appliances.
5. Post-processing
After printing, the dental appliance may require post-processing to prepare it for use. This can include cleaning to remove any residual uncured resin, removing support structures or sprues used in the printing process and performing any necessary finishing and polishing to ensure a smooth, comfortable and aesthetically pleasing final product.

3D printing materials
3D printing processes use biocompatible materials that are safe for use in the mouth and medical applications. Depending on the treatment, different materials may be used to meet specific requirements and provide the best possible results for your patients.
