Dental implants are a type of restoration of missing teeth based on an underlying structure that is implanted in the bone tissue to support and secure the upper dental prosthesis. It consists of a dental implant (implant-supported) and a dental prosthesis (implant-supported). The implant is made of artificial materials (e.g. metal, ceramic, etc.) and is surgically implanted in the tissue (usually in the upper and lower jaws) and is firmly supported by the bone tissue, and is connected to the upper prosthesis by special devices and methods. With the application of various oral implant techniques and bone grafting materials, the continuous improvement of implant systems, and the development of imaging and digital technology, patients with single tooth loss, multiple tooth loss and edentulous jaws can now receive implant restorative treatment and dental implants can achieve restorative effects that are very similar to the function, structure and aesthetic effects of natural teeth, and have become the preferred restorative method for more and more patients with missing teeth.
