  • METHOD FOR ATTACHING A DENTAL PROSTHESIS HAVING MULTIPLE ABUTMENTS
    Publication number: 20150037757
    Abstract: A method for attaching a dental prosthesis is disclosed. The prosthesis has multiple implants with different trajectories. In use, each implant is disposed within a patient's jawbone and their relative locations are mapped. The prosthesis is formed from multiple abutments with each abutment having a protrusion.
