Flapless Zygomatic Implants Robot-assisted Placement
A study testing Zygomatic implants in people with Zygomatic Implant and Robotic, run by Centre Hospitalier Universitaire, Amiens at 1 site in France.
Trial 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. Read more about this study

About this study
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Variation rate between theoretical intraoperative position and post-operative zygomatic implants position
The accuracy of zygomatic implants positioning will be evaluated by comparing the theoretical intraoperative position and the actual post-operative position by image fusion.
Measured: one day

Questions about this trial
What is this clinical trial studying?
A study testing Zygomatic implants in people with Zygomatic Implant and Robotic, run by Centre Hospitalier Universitaire, Amiens at 1 site in France.

The record says: status not confirmed, as of the sponsor's last update on 10 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?
Contact Sylvie TESTELIN, Pr (03.22.08.90.50, sylvie.testelin@chu-amiens.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Variation rate between theoretical intraoperative position and post-operative zygomatic implants position (time frame: one day). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jul 2024; AzTrials last refreshed its copy on 28 Oct 2026.
