Surgery day: Prosthetic steps
- The All-on-4® allows the patient to function post-operatively
- Temporary abutments must be used
- The provisional prosthesis can be fabricated by modifying the patient's existing complete denture
- Alternatively, the provisional prosthesis can be fabricated by using a prosthesis made during the planning phase
Following the attachment of the multi-unit abutments and recording of an appropriate torque value, a fixed provisional prosthesis, also called Conversion Prosthesis, can be attached to the multi-unit abutments.
This prosthesis is fabricated by either extensively modifying the patient’s existing complete denture or using a prefabricated prosthesis, so it attaches to the multi-unit abutments using metal temporary abutments with their incorporated screw retention.
