Understanding the distinct characteristics, strengths, and weaknesses of these formats is not only aimed at digital dentistry newcomers but also at seasoned professionals who are looking to enhance their understanding of these file formats. So, what are these formats, and why do they matter? Which format should you choose when exporting your scans? These scans are usually exported in three formats - STL, PLY, or OBJ files. So, it’s essential to save and select the correct file format when exporting and sending it through an order form if outsourcing to a lab.ĭepending on the scanner you use to capture your intraoral scans, different file formats can be exported to represent the 3D models of dental structures. Labs use third-party CAD software to preview the received STL, PLY, or OBJ files and create restorations based on these scans. But, navigating through this digital transformation is not without its complexities.Īll scanners these days have an ‘open architecture’ to allow for scans to be exported and sent to dental laboratories. These new technologies are transforming dental restoration fabrication and the patient experience. Today's dental professionals have advanced tools such as intraoral scanners (IOS), computer-aided design and computer-aided manufacturing (CAD/CAM) technology, and 3D printing at their disposal. No longer is there a need for traditional impressions using alginate or polyvinyl siloxane (PVS) materials to produce plaster casts.
As we enter an explosive new era in dentistry, the digital revolution is fundamentally changing the landscape of the profession.
