Root nails are medical fixation devices. The main materials are cobalt-chromium alloys, titanium-containing alloys, and pure titanium. Generally, root nails are made of materials that are easier to stretch and engage with the alveolar bone. According to the different materials, there are different types.

Root nails are the fixation devices used for dental implants when repairing missing teeth. Generally, root nails are made of materials that are easier to stretch and engage with the alveolar bone. According to the different production materials, they are also divided into different types. It can be used to produce tooth roots with various metal components. The biocompatibility and other characteristics of the roots are nickel-cobalt alloys, cobalt-chromium alloys, titanium-containing alloys, pure titanium, high gold, zirconia root nails, etc.

After the root canal treatment of the posterior teeth is completed, when the root nails are required, the root canals do not have a common positioning path. They can be made in two times, that is, the nails with the same positioning are first made, and then the root nails at the other end are made. If you do not make two times, the root nails will be very short and have poor retention.
