Dori, F., dr. Szabó, G.: The importance of the pure-phase ß-tricalcium phosphate (Cerasorh) in preprosth­etic surgery Short- and medium-term experience with a pure-phase ß-trical­cium phosphate bone-substitute material (Cerasorb) is reported on the basis of clinical, radiological (panorama, 2-3D CT records) and histological examination on 52 patients. The treatment modes on these patients included the filling of cysts, sinus grafting, augmentation and the filling of parodontal lesions. Disturbance of wound healing was not observed in any of the cases, and both the radiological and the histological examina­tions revealed that transformation of the implanted ß-tricalcium phosphate into bone could be detected as early as in the second month. During the 10-month follow-up period, this transforma­tion was continuous, but was not complete; completion is to be expected only after 12 months. It is important that load-bearing tissue had already developed after 4—6 months. Studies to date suggest that autologous bone is not necessary for either sinus grafting or the filling of large cysts: Cerasorb alone is suitable for this purpose. Key words: ß-tricalcium phosphate (Cerasorb), transfor mation, load-bearingtissue, praeprosthetic sur­gery 52
