A "root canal" is not a treatment, but part of a tooth. It is the hollow section of a tooth that contains the nerve tissue, blood vessels, and other cells, also known as the pulp. A tooth consists of a crown and roots. The crown is mainly above the gum, while the roots are below it. The roots attach the tooth to the jawbone. Inside the crown and the root, or the root canal, is the pulp. The pulp nourishes the tooth and provides moisture to the surrounding material. The nerves in the pulp sense hot and cold temperatures as pain. The name of the dental procedure commonly referred to as a "root canal" is actually endodontic therapy, which means "inside the tooth." However, the term "root canal" has come to be commonly used to talk about the procedure.
A dental implant (also known as an endosseous implant or fixture ) is a surgical component that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown , bridge , denture , facial prosthesis or to act as an orthodontic anchor . The basis for modern dental implants is a biologic process called osseointegration , in which materials such as titanium form an intimate bond to bone. The implant fixture is first placed so that it is likely to osseointegrate, then a dental prosthetic is added. A variable amount of healing time is required for osseointegration before either the dental prosthetic (a tooth, bridge or denture) is attached to the implant or an abutment is placed which will hold a dental prosthetic/crown.
