The treatment of hemimaxillectomy patients include the construction of an interim obturator in the wound healing period. With the aim of simplifying this process, we describe construction of an obturator in a short single visit, in the dental chair with no need for impressions or for laboratory services. The obturator comprises: (i) the surgical obturator and (ii) a hollow light-cured resin bulb built onto the base, and providing a large surface for bonding of the soft reline material. The advantages of this approach are rapid construction and ease of ongoing adjustment during the healing process.
Artificial modification of the shape of the vault has repercussions on the NMC that support the theory of an all-inclusive integration of the different cranial units in normal as well as in restricted development.
Deformity of the cranial vault exerts an influence on the mandible, supporting the theory of modular units in complete integration. This also supports the theory that mandibular prognathism is a multifactorial result and not a direct effect of displacement of the cranial base.
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.
