Surgical complications | No. of cases |
|---|---|
Treatment planning related | |
During implant, placement reconstruction screw hit and reconstruction screw were removed to accommodate the implant | 2 |

Anatomy related | |
Difficult surgical access to place implants so implants were not placed | 2 |
The implant was not placed as there is a high risk of inferior dental nerve damage | 1 |
CAD-CAM surgical guide made access more challenging so it was not used to prepare posterior sites | 1 |
Lack of bone volume to place implant—so an alternative site was used | 3 |
Large incisions were required to attain surgical access to fit the CAD-CAM surgical guide which was deemed inappropriate and the implants were subsequently placed free hand | 1 |
Procedure related | |
Lack of primary stability of the implant so larger implant diameter was used to achieve primary stability | 4 |
Lack of primary stability of the implant—implants left in situ | 2 |
Lack of primary stability of implants—so the implant was not placed | 1 |
Lack of primary stability of the implant—so the implant was placed in an alternative site | 1 |
The implant was not placed due to being placed too deep | 1 |
