Clinical Trial Summary

This study consists in a randomized controlled trial which objective is to assess the accuracy of a dynamic navigation system in zygomatic implant placement in partially or total edentulous patients in the upper jaw compared with the conventional freehand method.

Description:

The present study is a prospective randomized clinical trial.

Each patient enrolled in this trial will be randomly allocated to on group (Navigation group (test group) or Freehand group (control group)). Preoperative virtual planification of zygomatic an conventional implants on a prerequired cone beam computed tomography (CBCT) with radiographic markers (tooth if possible or micro implants if not possible) will be performed for each patient.

The patient will be randomly allocated in one group just before the surgery, and the surgical procedure will be performed according the surgery protocol of each group. Then, after the surgical procedure a PROMs questionnaire will be asked to the patients.

Finally a postoperative CBCT will be performed and overlapped with the preoperative CBCT with the implants planification and implant position deviations between the planned and final position will be measured.

The study devices are European Conformity (CE) marked products and used within their intended use.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Angular deviation	Angular deviation between the virtual planed position of the implant and the final implant position. Measured in degrees	1 month
Primary	Platform 3D deviation	Global deviation at the platform of the zygomatic implant between the virtual planned position and the final position of the dental implant measured in the 3 axes of the space (3D deviation). Measured in millimeters (mm).	1 month
Primary	Apex 3D deviation	Global deviation at the apex of the dental implant between the virtual planned position and the final position of the dental implant measured in the 3 axes of the space (3D deviation). Measured in millimeters (mm).	1 month
Secondary	Patient-reported outcome measures questionnaire	Patients perception of therapy functional well-being and health status during the dental implant treatment with a navigation system. The scale goes from 0 to 4, where higher scores mean worse outcome.	One week post operative
Secondary	Time of surgery	Two times of surgery were recorded: time of drilling, from the first drilling of the first zygomatic implant to the last zygomatic implant placement; and time of complete surgery procedure, from first incision to suture.	24 hours
Secondary	Complications	Number of intra and postoperative complications and what kind of complication it was.	6 months
