Study to Evaluate Implant Survival Rate of Astra Tech Fixture ST in the Posterior Maxilla With One-stage Surgery and Early Loading

An Open Prospective Study to Evaluate the Survival Rate and Marginal Bone Response of Astra Tech Dental Implants, Fixture ST, in Patients With Tooth Loss in the Posterior Maxilla.

NCT00748241•Dentsply Sirona Implants and Consumables

View on ClinicalTrials.gov

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.
