Brief summary
Zygomatic implants are indicated for the rehabilitation of the severely atrophic maxilla. Similar to standard implant placement, gaining an optimal position of the zygomatic implants is essential for a predictable prosthetic-driven treatment outcome. However, there is no effective mechanism to physically control the drilling trajectory for the zygomatic implants. Therefore, deviation between the actual and planned implant position is inevitable. This approach is technically difficult, and is performed by an experienced surgeon. The development of a surgical technique that is both safer and less invasive is currently possible thanks to robotics. In this project, a robotic assisted new strategy for positioning zygomatic implants will be performed and its efficacy and accuracy will be assess. Path planning will be carried out on a pre-operative scanner. The ROSA robot (Zimmer®) will guide the several drillings steps. Placement of the zygomatic implant will be performed manually.
