Zygoma implant-supported prosthetic rehabilitation after partial maxillectomy using surgical navigation: a clinical report


Kreissl, M E; Heydecke, G; Metzger, M C; Schoen, R (2007). Zygoma implant-supported prosthetic rehabilitation after partial maxillectomy using surgical navigation: a clinical report. Journal of Prosthetic Dentistry, 97(3):121-128.

Abstract

The rehabilitation of patients with acquired defects of the maxilla is a challenge in terms of reestablishing oronasal separation. In most patients these goals are met by means of prosthetic rehabilitation with an obturator prosthesis. If the remaining dentition does not offer sufficient retention and support, the placement of zygoma implants can enhance the stability of the prosthesis. Due to the anatomic intricacies of the zygomatic bone and the implant length, computer-supported navigated implant placement can be advantageous. In the following clinical report, a diabetic patient with a status of posthemimaxillectomy secondary to aspergillusis infection is presented, in whom a zygoma implant was placed using a CT scan-based navigation system. A special retentive anchoring abutment was used to integrate the zygoma implant into a telescopic crown-retained denture on the residual dentition. This tooth-implant-supported obturator prosthesis restored function and phonetics, as well as esthetics, for this young patient.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
