[Indications and results of transdental fixation with the Wirz Syntacoben screw in frontal tooth reconstruction].

In a one-armed prospective study including 60 patients (27 male, 33 female; age 17-75 years), 109 teeth were treated by means of a screw system made of Syntacoben and Niob according to Wirz. 103 teeth were transfixed successfully: 48% of them were provided with a partial removable denture; 34% were used as a bridge pier; 11% underwent conservative treatment; in 7% prosthetic treatment is planned. The use of the Wirz-System for primary transfixation combines in an ideal way the advantages of endodontic conservation and the ready-made post with the improved stability of the prosthetic pier.
