Immediate Stabilization and Function / Bicon Integrated Abutment Crowns™: Placement of Maxillary Left Lateral Incisor with Bovine Graft and Bicon Resorbable Collagen Membrane and Restoration with a Bicon Integrated Abutment Crown™
This case demonstrates the extraction of a failed endodontically treated maxillary lateral incisor, subsequent bovine bone allograft with a Bicon Resorbable Collagen Membrane, placement of an immediately stabilized and functioning implant, fabrication of three bonded transitional prostheses, implant level impression, and an insertion of a Bicon Integrated Abutment Crown™.
