Implant dentistry refers to the restoration of a missing tooth based on a substructure implanted in the bone tissue to support and anchor the upper dental prosthesis. It consists of a dental implant 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 jaw) and is firmly supported by the bone tissue.
