Clinical progress on restoration by chairside CAD/CAM inlay

Tooth defects due to dental caries, trauma, abrasion, etc., are extremely common and can be treated by direct or indirect restoration. Compared with resin directly filling the body, an inlay can better restore the occlusal contact relationship and the adjacent surface contact relationship and has good mechanical properties. In recent years, with the development of ceramic materials and bonding systems and the popularity of chairside CAD/CAM technology, the chairside CAD/CAM porcelain inlay restoration program has been well received by doctors and patients because of its accuracy, convenience, aesthetics, hardness and stability, and this program is widely used clinically. This review covers the research status of various aspects such as indications and contraindications for chairside CAD/CAM inlay restoration, pre-restoration preparation, tooth preparation, hole type, impression taking and design, porcelain block selection, bonding, polishing, postoperative doctor's instructions, and common postoperative complications. It is expected to provide a reference for the clinical application of and research on chairside CAD/CAM inlay restoration technology.
