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

Mansoura University20 enrolled

Overview

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.

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

Conventional Prosthetic WorkflowPROCEDURE

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.

Digital Jaw-Tracking WorkflowPROCEDURE

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.

Outcomes

Primary Outcomes

Patient Satisfaction

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.

Time frame: At prosthesis insertion, 3 months, and 6 months after prosthesis insertion

Secondary Outcomes

Occlusal Accuracy

Occlusal accuracy will be evaluated using the OccluSense digital occlusal analysis system by assessing the distribution and stability of occlusal contact points.

Time frame: At prosthesis insertion and 3 months after insertion
