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

Jaw Tracking Impact on Occlusion and Patient Outcomes in Maxillary Implant Restorations: Randomized Clinical Trial

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.

Study Overview

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Conventional Workflow
Participants will receive full-arch maxillary implant-supported screw-retained restorations fabricated using the conventional workflow with conventional jaw relation records and standard occlusal adjustment procedures.
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.
Experimental: Digital Jaw-Tracking Workflow
Participants will receive full-arch maxillary implant-supported screw-retained restorations fabricated using a digital workflow incorporating dynamic jaw tracking and a virtual articulator for patient-specific occlusal design.
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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Patient Satisfaction
Time Frame: 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.
At prosthesis insertion, 3 months, and 6 months after prosthesis insertion

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Occlusal Accuracy
Time Frame: 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.
At prosthesis insertion and 3 months after insertion
