SURVEY OF INCIDENCE AND THERAPEUTIC PRINCIPLES OF PATIENTS WITH TEMPORO-MANDIBULAR DISORDERS AT SZEGED UNIVERSITY BETWEEN 2003 AND 2005 PERÉNYÍ, J. HORVATH, G Department of Prosthodontics, Faculty of Dentistry, University of Szeged, Hungary The Clinic of Dentistry and Oral Surgery of Szeged University serves as a regional centre for treatment of patients with temporo-mandibular joint disorders. Patients treated with this diagnosis in the period 1st October 2003 - 31st December 2005 were analysed according to age, sex, diagnosis, place of residence and applied therapy. Patients were recalled for control, and symptoms and signs were rated according to Helkimo’s index, while the pain-values were graded in pursuance of markings made by the patient on a visual analogue scale. The obtained results give us the possibility to evaluate the efficiency of different treatment methods. PROSTHODONTIC REHABILITATION AFTER COMPLEX TREATMENT OF SUBLINGUAL CANCER PERGER, K.1, KIVOVICS, P.1, HAJDÚ, Z.2 department of Prosthodontics, Faculty of Dentistry, Semmelweis University, Budapest, Hungary; technician Laboratory of Semmelweis University, Faculty of Dentistry, Semmelweis University The prosthetic treatment of patients after oral cancer treatment needs consideration of some important rules. Few prostheses do not cover the surgical area toward perspicuity and controlling this area. The prostheses do not cause irritation on the mucosa. The altered clinical anatomical situation has to be most carefully considered at the impression procedure and the developing of surfaces of the prosthesis. If the patient has only two lower canine, there are many possibilities for the prosthetic treatment: from the RPD without tooth preparation to the most complicated prostheses with precision attachments. Many factors influence our choice. Our patient had also this status. The prosthodontic rehabilitation was performed after tongue and sublingual resection due to a cancer (Stage III) and radiation therapy. Due to the surgical procedure the half of the tongue is missing and there is a limitation in mobil99. évf. 6. sz. 2006. ity of the tongue and the lower lip. According the special clinical anatomical situation we planned a special lower prosthesis. Upper complete denture and lower mucodental supported RPD with precision attachments were made. Conical telescopes were used on the canines splinting with dental bar with Wirofix friction elements. Prosthodontic rehabilitation restores not only the masticatory function and the aesthetics but it improves also the voice production. The patient is satisfied with the prostheses and has worn it without complaints for a yean References: 1. BEGO Bremer Goldschlägerei Wilh.
