Dental Implants provide structure and a foundation. An implant may be used to replace almost any missing tooth, provided there is adequate bone at the site. If not, modern procedures can usually be performed to regenerate enough bone to safely place an implant. The implant is placed in the bone below the gum tissue. A temporary abutment may be placed on the implant until the healing phase is complete. A cosmetic temporary crown is often made to fill the missing space.
