Dental implant. Artworks showing the process of replacing a tooth (incisor) with a dental implant. At upper left, front lower teeth and a dental instrument are shown in a case of receding and inflamed gums. This is typical of conditions such as gingivitis and periodontal disease. If not checked, erosion of the teeth and gums leads to loss of the teeth. At upper right is the internal structure of a tooth (molar), including arterial (red) and venous (blue) capillaries, and the tooth layers (enamel, dentine, pulp, cementum). Across bottom, a hole is drilled in the jaw bone, a titanium base implanted, and the artificial tooth screwed into this base.
