Dental implant is defined as a prosthetic device or alloplastic material implanted into oral tissues beneath the mucosal or periosteal tissues, and onor with in the bone to provide retention and support for fixed or removal prosthesis. The goal of modern dentistry is to restore the stomatognathic system to normal function, comfort, esthetics, speech and health regardless of the atrophy, disease or injury. As a result of continued research in dental implant designs, materials and techniques, predictable success is now a reality for the rehabilitation of many challenging clinical situations.

Oral cancer is one of the most prevalent cancers of the world. It is among the top ten reasons to cause death. Oral cancer ranks one among all the cancers caused among men, which represents 4% of all deaths among men. In women it stands third among all cancers and represent 2% of all deaths. Oral cancer due to its location in the most accessible part of the body, i.e. the mouth it can be detected in the early stages. However, because of lack of symptoms, especially pain, it is neglected and often recognized at the advanced stage thus a proper medical care is not reached in the initial stage....

Periodontitis is an inflammatory disease of periodontium. The relationship between bacterial plaque and the development of periodontal disease is well established. Antibacterial agents have been used effectively in the management of periodontal infection. The effectiveness of mechanical therapy and repeated systemic administration of antibacterial agents are limited due to the lack of accessibility to periodontopathic organisms in the periodontal pocket. Systemic administration of drugs leads to therapeutic concentrations at the site of infection, but for short periods of time, forcing...

Replacing lost teeth with dental implants is today a reliable treatment method associated with good long-term clinical results. Different surface modifications and implant design alter the surface topography at micro- and nano-meter level of resolution as well as chemical properties, which have shown to be of importance for osseointegration. Research within the field of implantology is still intense and aims at further improving the implant properties to achieve successful treatments for patients with compromised bone as well as developing a surface that provides faster integration to...
