Brief summary
This randomized clinical trial aims to evaluate the effect of integrating digital jaw tracking into the workflow for fabrication of full-arch maxillary implant-supported screw-retained restorations. Twenty completely edentulous maxillary patients opposing natural mandibular dentition will be randomly assigned to either a conventional workflow group or a digital jaw-tracking workflow group. The study will compare patient satisfaction and occlusal accuracy between the two groups. Patient satisfaction will be assessed using a visual analogue scale (VAS), while occlusal accuracy will be evaluated using the OccluSense system.
Detailed description
This randomized clinical trial will compare conventional prosthetic workflow with a digital jaw-tracking workflow for the fabrication of full-arch maxillary implant-supported screw-retained restorations. Twenty edentulous patients with completely edentulous maxillary arches opposing natural mandibular dentition will be recruited and randomly allocated into two equal groups. Group A will receive restorations fabricated using the conventional workflow with static jaw relation records, while Group B will receive restorations fabricated using a digital workflow incorporating dynamic jaw tracking and a virtual articulator. The primary outcome will be patient satisfaction, assessed using a visual analogue scale (VAS) after prosthesis insertion and during follow-up visits. Occlusal accuracy will be evaluated using the OccluSense digital occlusal analysis system. The study aims to determine whether digital jaw tracking improves occlusal accuracy and patient-reported outcomes compared with the conventional workflow.
Interventions
PROCEDUREConventional Prosthetic Workflow
Fabrication of a full-arch maxillary implant-supported screw-retained prosthesis using conventional jaw relation records, a facebow or average-value articulator, and conventional occlusal adjustment procedures.
PROCEDUREDigital Jaw-Tracking Workflow
Fabrication of a full-arch maxillary implant-supported screw-retained prosthesis using a digital workflow with dynamic jaw tracking, virtual articulator integration, and CAD/CAM technology for patient-specific occlusal design.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Patient Satisfaction | At prosthesis insertion, 3 months, and 6 months after prosthesis insertion | Patient satisfaction will be assessed using a Visual Analogue Scale (VAS) to evaluate patient satisfaction with the implant-supported prosthesis regarding comfort, chewing ability, aesthetics, and phonetics. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Occlusal Accuracy | At prosthesis insertion and 3 months after insertion | Occlusal accuracy will be evaluated using the OccluSense digital occlusal analysis system by assessing the distribution and stability of occlusal contact points. |
