Maxillary restoration with full arch fixed prosthesis on six implants

A decision to restore the maxilla on a 44 -year old patient with a full-arch fixed prosthesis on six implants was taken. The implants would replace an immediate full denture.
  • Treatment provider: Dr. George Michelinakis
  • Solutions used: 3Shape TRIOS intraoral scanner
  • Dr. Michelinakis uses digital scans and software to simulate implant placement and create a pilot-guide surgical stent and 3D print it.


  • Mapping the patient’s upper arch with CBCT data. Radiolucent cone beam markers are attached to the patient’s existing complete upper denture which is then scanned with a ProMax 3D Mid CBCT appliance.
  • Implant fixture placement. Following surgical stent fabrication, six Straumann STL RN implants are inserted in the maxilla using a flapless approach.
  • Scan bodies. Following 4 months of healing, the maxillary arch with attached scan bodies is scanned using a 3Shape TRIOS intraoral scanner.
  • Digital workflow benefits. The patient did not need to undergo a full arch conventional impression in the maxilla or the mandible, his occlusal parameters were digitally registered with high accuracy with the impression and bite registration completed in only one appointment, which shortened the treatment time by at least 2 clinical sessions.
