Fully Digital Workflow: An All On 4 Case Study

Digital Scans

This case was done using a completely digital workflow. The first step in gathering the necessary data was to scan the implant sites to measure the exact orientation and position of the implants. This was done using Imetric4D’s ICam4d extraoral scanner. This scanner is an excellent option for multi-implant scans.

The iCam4d system uses special scan bodies to record the implant position.

The scan bodies (iCambodies) are inserted in the patient’s implant sites. They should not be torqued down but should be hand-tightened.

These scan bodies contain unique 3D coding that provides the location data of the implant in a digital format. This data is captured using the iCam4d systems extraoral scanner. The accuracy of these scans is within 10 to 15 microns.

Next, the scan bodies were removed. The soft tissue and bites were then recorded. These scans were done using the 3Shape scanner.

The data from both the abutment scan and the soft tissue scan was then sent to the digital portal at Burbank Dental Lab. You can access the portal from the home page at https://burbankdental.com. These scans were then aligned to become the digital representation of the patient’s mouth.

Dr. August de Oliveira sent an additional bit of digital data in the form of a 3D face scan. This was used as a visual aide to relate the face to the digital model. This helped provide another bit of data to help ensure a correct midline.
