Sponsor: Dentsply Sirona Implants

Current Primary Outcome: Implant Survival Rate [ Time Frame: At 5-year follow-up ]

An implant that has failed to osseointegrate, lost its osseointegration or fractured was considered a failure effective from the date of removal. The survival rate for individual implants was analyzed at each visit. Cumulative implant survival rate was calculated using Kaplan-Meier life-table estimation and reported as percentage of survived implants.


Original Primary Outcome: Implant Survival Rate [ Time Frame: From implant placement until 5-year follow-up ]
