Cumulative Survival of Maxillo-Mandibluar and Gender Comparison in Edentulous Implant Over Denture Cases

Abstract

The cumulative survival rate (CSR) of 112 Eichner index C2 and C3 edentulous cases with implant overdenture (IOD) was analyzed by means of Kaplan Meier survival curve and logLank test. The CSR was calculated from days after IOD superstructure placement to implant removal due to periimplantitis or implant fracture. The femaleʼs CSR showed higher CSR than male and mandibular lOD showed higher CSR than maxilla, respectively. On the other hand, Eichner indexʼs subclass C3 showed higher CSR than C2. In gender comparison of C3 also showed higher female CSR than male and higher CSR in the mandibular than maxilla. Further long-term studies are required to take into account the diversity in the form of defects in the opposing jaws and the designs of prosthetics.
