Dental implants are lasting, stable tooth replacements that can be used to replace one missing tooth, several missing teeth or complete arches of teeth. The dental implant post, which is a screw made of titanium, is surgically placed in the jawbone at the site of the missing tooth. It replaces the missing tooth root and ensures that your dental restoration is stable. A period of healing is then often required to allow the bone to begin to bond with the biocompatible post.
