Permanent Resin Restorations Fabricated by Three Dimension Printer

Additive manufacturing (AM) and 3D printing (3DP) technologies have advanced significantly in many different areas. With the time and cost advantage it provides in low-volume production, 3D printing technologies also come to the fore in the field of digital dentistry. A tooth-coloured, ceramic-filled permanent resin has been introduced by the manufacturer for the 3D fabrication of permanent single crowns, veneers, inlays and onlays. The aim of this clinical study was to clinically evaluate the long-term survival and intraoral performance of 3D-printed permanent resin. to the ICDAS caries classification system, 20 volunteers between the ages of 18-65 with class II caries lesion at D1 or D2 level were included in this study. Restorations were checked 1 week (baseline) and 6 months after completion and scored using the Modified Ryge Criteria (USPHS2(United States Public Health Service)). Statistical analysis was done by Kaplan-Meier survival analysis.

The design and manufacture of 3D printed restorations relies on the exchange of digital information (data) between 3D imaging, 3D virtual planning and/or 3D printing technologies. One of the key points in the widespread use of 3D printers is the emergence of these systems that allow data from different sources to be used in a personal computer with various design and production technologies. It saves Digital Imaging and Communication in Medicine (DICOM) files in STL format. STL files can be printed and processed with various CAD/CAM systems in local manufacturing or remote labs. This is an important advantage of using open source. With these systems, it is possible to produce restorations with clearer anatomical features thanks to current 3D printing technologies. In other words, low-cost restorations with more useful properties can be produced.
