Abstract

After the resection of oral tumor, defected maxillofacial structure caused functional difficulties including phonetics, mastication and esthetic aspects. In this cases, implant retained prosthesis can contribute to the functional enhancement. Regardless of the success rate in grafted bone, however, the soft tissue usually had a shape which was susceptible to inflammation. Moreover, infected graft bone presented rapid destruction. For success of the prosthetic treatment, adequate soft tissue treatment and frequent recall check are the essential factors to the successful implant prognosis.
