  • Title: [Implant-supported prostheses for the edentulous patient after partial maxillectomy--clinical considerations in the choice of retention elements--2 case reports].
    Author: Nothdurft FP, Pospiech PR.
    Journal: Schweiz Monatsschr Zahnmed; 2007; 117(1):28-41. PubMed ID: 17330663.
    Abstract:
    The prosthetic rehabilitation of edentulous patients following hemimaxillectomy proves to be functionally unsatisfactory in many cases because of a heavily changed oral morphology and oral communication with the nasal and maxillary sinus cavities, which makes it difficult to achieve a sufficient retention and stability of the restoration using a conventional obturator denture. Using implants as anchorage increases comfort considerably for patients wearing such restorations. Due to the wide variety of the individual anatomy of the defect area and the residual parts of intact maxilla clinicians are confronted with advanced challenges according the preprosthetic planning and technical realization. Moreover, a close interdisciplinary cooperation between prosthetic dentistry and maxillofacial surgery is necessary to guarantee a successful treatment. By the means of two patients the rehabilitation with implant-borne dentures is demonstrated. Considering individual demands one patient was treated with telescopic crowns, the other with a bar system. The procedure of the prosthetic rehabilitation is presented. Aspects which arise from the specific case situations should be of special interest. In spite of the problematic initial situation the rehabilitation of the patients resulted in esthetically and functionally sufficient restorations.
