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.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
