Ti合金ピンを用いたピンブリッジ法の遠隔予後調査 A Longitudinal Follow-up Study of the Partial Edenturism Patients Treated by a Pin Bridge Technique
In the current study, the longitudinal survival rate of Pin Bridge (first described by Yamashita et al., 1996) was compared and contrasted with that of full coverage bridges luted by conventional cements. Subjects of this study was 41 patients (46 cases) who consulted the fixed prosthodontic clinic from January 1984 to January 1998. The determination of survival or failure of the restoration for any reason was based on data from clinical and dental x-ray examinations. Then Kaplan-Meier analysis for the survival rates and Log-rank test for testing difference in the rates between the groups were employed. As a result, the survival rate of the Pin bridge (75.7%) was almost identical to that of the full coverage bridge luted byconventional cement (63.1%)(p=0.3518) 10 years after installation. These data suggested that the survival rate of the Pin Bridge was as high as that of the conventional full-coverage bridge even with a relatively noninvasive nature of the pin restoration.
