An Open, Randomized Study to Compare Two Dental Implant Systems With Regard to Changes in Marginal Bone Level.
The purpose of this study is to compare marginal bone level changes between ASTRA TECH
Implant System; Fixture ST and Biomet 3i; Osseotite® Implants. Subjects with partial
edentulism in the posterior maxilla and/or mandible will be included and a one-stage
surgical protocol will be used. Implants will be loaded within 15 weeks from installation.
The subjects will be followed for 3 years.
