Additional Information

Official title A Prospective Randomized-Controlled Evaluation of an Implant System With a Novel Abutment Attachment Design for the Preservation of Crestal Bone
Principal investigator Jorge Arango, DDS
Description In this study patients are randomized to receive either the experimental implant system or the control Nanotite Certain Tapered (standard abutment connection) and assessed for integration success measured by lack of implant mobility and lack of bone loss obtained at various study time points
