ABSTRACT Implant can be defined as “any object or material such as alloplastic substance or other tissue which is partially or completely inserted into the body for therapeutic, diagnostic, prosthetic or experimental purpose”. The goal of implantology is to restore the normal contour, function, comfort, esthetics, speech and health of the patient. Replacement of missing tooth with dental implant offers more advantages including preservation of the alveolar crest, improved aesthetics and function.
