A dental implant is a screw, most of the time in biocompatible titanium which is fixed in the jawbone. It allows replacing the root of a tooth. On the dental implant will be fixed a fixed or removable prosthesis. It may be a crown when it comes to replacing a tooth or a bridge when it comes to several teeth. In the case of the All On 4 or All On 6 system, it is a denture that is said to be stabilized by dental implants.
