Patient: 55 years old male
Chief complaint: "I can't chew on either side."
Diagnosis: complete denture on top
C8_Digital_01
3 implants were placed in patient’s lower left quadrant to restore 4 posterior teeth (two premolars & two molars)

C8_Digital_02
This is 10 days after surgery. You can see the minimal healing around implants and also in the extraction sockets.

C8_Digital_03
without healing abutment.

C8_Digital_04
Provisional restoration was delivered. And This is how the tissue looks 3 weeks post-op.

C8_Digital_05
Healing abutments were connected to the fixtures.

C8_Digital_06
Soft tissue was molded based on the contour of provisional restoration.

C8_Digital_07
To transfer the custom-molded soft tissue information onto the working model, the provisional restoration was picked up with the impression instead of impression copings.

C8_Digital_08
The CAD designing process of custom abutments.

C8_Digital_09
CAD/CAM custom abutments on the working cast.

C8_Digital_10
The final restoration closely follows the contour of the provisional restoration and well adapts to the custom-molded soft tissue.

This case presents provisional restoration delivered 3 weeks post-op and how the soft tissue was molded based on the contour of provisional restoration. To transfer the custom-molded soft tissue information onto the working model, the provisional restoration was picked up with the impression instead of impression copings.

    Nice case. I have one question, you have been showing that you used a CAD CAM customized abutment in order to shape the tissues. However i was informed that neobiotech doesnt provide its STL files to be imported to exocad library. So please correct me if am wrong. again nice case
