Abstract:Body abnormalities or defects that compromise appearance, function may make an individual, incapable of leading a relatively normal life. Facial disfigurement can be the result of a congenital anomaly, trauma or tumour surgery. Surgical reconstruction may not be possible owing to size or location of the defect. The patient's medical condition or personal desires may also preclude reconstructive surgery. In such cases, prosthetic rehabilitation is indicated. A facial prosthesis restores normal anatomy and appearance, protects the tissues of a defect, and provides great psychological benefits to the patient. A number of materials are available and have been used for fabrication of maxillofacial prosthesis; the aim of this article is to provide some insight about the currently used maxillofacial prosthetic materials.
The esthetic and functional rehabilitation of a missing anterior tooth is one of the greatest challenges that the dentist faces. Generally accepted treatment modalities include implant-supported prosthesis or fixed dental prosthesis. Recent advances in technology and dental materials have prompted the use of all-ceramic crowns which offers the potential for improved aesthetic results compared to conventional ceramo-metal crowns. Silica/glass-based allceramic crowns are more translucent and have better optical properties. However, they are mechanically weaker and need to be used in conjunction with resin bonding cements. To overcome such shortcomings, newer ceramic materials like Zirconia have been established during past few years which have better mechanical and optical properties. This case report summarizes the use of Zirconia crown for achieving the best possible esthetic rehabilitation of a missing upper right central incisor in a 35 year old female patient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
