Bicon Integrated Abutment Crowns™ / Immediate Stabilization and Function / Short Implants:

Extraction of a Maxillary Central Incisor and Restoration of an Immediately
Placed and Functioning Short Implant with an Integrated Abutment Crown™
This case demonstrates the extraction of a maxillary left central incisor with internal resorption and the insertion of an immediately stabilized short implant along with its restoration with an Integrated Abutment Crown™.
