Craniofacial prostheses, also known as epistheses, are artificial substitutes for facial defects. The breakthrough for rehabilitation of facial defects with implant-retained prostheses came with the development of the modern silicones and bone anchorage. Following the discovery of the osseointegration of titanium in the 1950s, dental implants have been made of titanium in the 1960s. In 1977, th...

The main condition for speech intelligibility is the specific anatomical characteristics of the human speech apparatus and harmonious work of all organs in the human vocal apparatus. The voice quality is characterized by speech intelligibility (relationship between the voice pitch, volume, timbre and speech speed). Improper functional quality (related to retention,support, stability), inappropr...

PURPOSE This systematic review aimed to evaluate the effect of implant length on peri-implant marginal bone loss (MBL) and its associated influencing factors. MATERIAL AND METHODS An electronic search of the PubMed and MEDLINE databases for relevant studies published in English from November 2006 to July 2012 was performed by one examiner (AM). Selected studies were randomized clinical trials...

There is general agreement that excessive stress to the bone-implant interface may result in implant overload and failure. Early failure of the implant due to excessive loading occurs shortly after uncovering the implant. Excess load on a final restoration after successful implant integration can result in physical failure of the implant structure. Many clinicians believe that overload of denta...

With the advent of titanium, root form implants and osseointegration, dental treatment has undergone a metamorphosis in recent years. These new techniques enable dentists to provide anchorage for various kinds of prostheses that improve masticatory function, esthetics, and comfort for patients. Implant treatment protocols have been improved relative to implant macro- and micro-geometries, surgi...

Removable prosthodontics are often associated with mechanical troubles in daily use, such as fracture or deformation. These troubles render prostheses unusable and reduce wearers' QOL. Various reinforcements are used to prevent such problems, but consensus on reinforcement has not been reached. This review aimed to summarise the effects of reinforcement and to propose favourable reinforcement b...

Teeth are the most durable and enduring structures of human anatomy, surviving fragmentation, partial incineration and severe decomposition. The role of teeth in identification is manifested as significant specifiers of deceased or living individuals. The characteristics of dental morphology are genetically-inherited and ascribable to racial or familial ancestry. Dental age identification is at...
