Zirconium oxide-based ceramic restorations made in the patient after pituitary gland tumour surgery: A case report
Journal Title: Prosthodontics - Year 2011, Vol 61, Issue 1
Abstract
Ceramic restorations are made because of aesthetic indications or the necessity for metal elimination in the oral cavity. The metal alloys especially those including iron may distort the results of periodical MR examinations carried out among prosthodontic patients.A-28 year-old patient after surgery and radiotherapy due to pituitary gland tumour has reported to the Department of Prosthodontics applying for prosthetic treatment. The clinical extraoral examination revealed a significantly decreased vertical dimension and angular cheilosis. The intraoral examination showed the loss of teeth in the interior and superior dental arches (classes III and IV in the Galasinska classification), thin mucous membrane on the edentulous alveolar and caries-destroyed teeth requiring denture restoration.A double-stage treatment was designed. At the first stage, two removable partial dentures were made in the proper vertical relation and the required endodontic treatment was performed. After a four-month adaptation period the second stage of treatment began. The destroyed teeth in the interior and superior dental arches were restored by fibreglass post-and-core. The use of fibreglass was necessary to avoid the presence of metal in the oral cavity.The superior dental arch was restored by two ceramic bridges, ceramic crown and the framework. In the interior dental arch a complete reinforced overdenture, supported on the telescope crowns, was made. The fibreglass-restored teeth, covered with zirconium oxide caps, formed internal crowns. The teeth in the overdenture with particular PMMA inserts were external crowns. The CAD/CAM technology was used to construct permanent restoration in the superior and interior dental arches.After prosthetic treatment the functional and aesthetic results were achieved and conditions of legible radiology diagnostics were ensured.
