Study Summary
The purpose of this study is primarily to evaluate implant survival rate of Astra Tech Fixture ST placed in the posterior maxilla. A one-stage surgical protocol will be used and the implants will be loaded four weeks after implant installation (early loading). Marginal bone levels, plaque and status of the periimplant mucosa will also be evaluated. The subjects will be followed for three years.
Primary Outcome
An implant that has failed to osseointegrate, lost its osseointegration or fractured will be considered a failure effective from the date of removal. Implant Survival Rate will be calculated using the Kaplan-Meier method based on the number of placed implants. Patients who discontinued the study after the last implant failure do not affect the cumulative survival rate.
