Immediate Stabilization and Function / Bicon Integrated Abutment Crowns™ : Placement and Restoration of Four Maxillary Incisor Implants in Three Clinical Visits
This case demonstrates the extraction of maxillary incisors and the surgical placement of four immediately functioning implants and their permanent restoration with Bicon Integrated Abutment Crowns™ in three clinical visits in a time period of 97 days. This case also demonstrates the use of a caliper device for the fabrication of custom seating jigs.
