  1. These multivariate odds ratios for maintenance discontinuation were adjusted for address, sex, age at implant placement, PCR level at the initial visit, PCR level following attachment of the superstructure, the number of implants, and the number of missing teeth
  2. Age age at implant placement, PCR PCR level following attachment of the superstructure
