Jaw Tracking Impact on Occlusion and Patient Outcomes in Maxillary Implant Restorations

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.

Exclusion criteria

• Systemic diseases affecting bone healing, such as uncontrolled diabetes mellitus or osteoporosis.
• Harmful oral habits, including smoking, clenching, or bruxism.
• Uncooperative patients or patients unable to comply with study procedures.
