A study sponsored by the National Institute of Dental Research has as its major goal the development of easily fabricated and implantable dental anchors for replacement of missing or extracted teeth. Tissue ingrowth fixes the anchors in the mandibular or maxillary bone where they can serve as a base for future attachment of prefabricated dental caps, bridges, or other dental prostheses. More immediate objectives are to determine the suitability of specific porous titanium and ceramic materials for anchor applications, to develop satisfactory designs and fabrication procedures for producing these devices, and to define material/bone interface bonding characteristics through in vivo studies. The value of the Hanford Miniature Swine as a human analog for dental research is being assessed concurrently.
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.
