The main clinical work of restorative dentistry is to restore the anatomical form and physiological function of the missing part of the teeth through various artificially made restorations, such as crowns and dentures, to maintain the health of the oromandibular system and indirectly to promote general health. In short, it is to restore the patient’s chewing function by placing teeth. Restorative dentistry requires the doctor to master the theoretical knowledge of oral anatomy and physiology, physiology and restorative dentistry, as well as the principles and methods of biomechanics, materials, aesthetics, and restorative techniques. In addition to understanding multidisciplinary knowledge, the doctor is required to have a certain level of aesthetics and good hands-on skills. Therefore, hand skills are necessary for the prosthodontist.
