Dynamic Occlusal Design Using Jaw Motion Data for Maxillary Full-Arch Implant Rehabilitation: A Retrospective Study

Area of Science:

• Dental Implantology
• Biomaterials Science
• Digital Dentistry

Background:

• Maxillary full-arch implant rehabilitation aims to restore function and aesthetics.
• Conventional static digital workflows may lead to occlusal discrepancies and prolonged chairside adjustments.
• Mandibular motion analysis offers a dynamic approach to capture jaw movements for improved prosthesis design.

Purpose of the Study:

• To evaluate the clinical efficacy of prostheses designed using mandibular motion analysis compared to conventional methods in maxillary full-arch implant rehabilitation.
• To assess the impact of dynamic occlusal data on occlusal adjustment depth, area, and chairside time.
• To evaluate the effect on oral health-related quality of life (OHRQoL) and mandibular movement stability.

Main Methods:

• A comparative study involving 20 patients undergoing maxillary full-arch implant rehabilitation.
• Study group (n=10) received prostheses designed with dynamic occlusal data from a jaw motion analyzer (JMA).
• Control group (n=10) used conventional static digital workflows. Occlusal adjustments, chairside time, OHRQoL (OHIP-14), and mandibular movement paths were analyzed.

Main Results:

• The study group showed significantly lower occlusal adjustment depth and area compared to the control group.
• Chairside adjustment time was reduced by approximately 30% in the study group.
• Patients in the study group reported significantly better OHRQoL, particularly in 'Meal interruption' and 'Relaxation difficulty' domains.

Conclusions:

• Integrating dynamic mandibular motion data into prosthesis design optimizes functional outcomes in full-arch implant rehabilitation.
• This digital approach minimizes occlusal adjustments, reduces chairside time, and enhances patient-reported quality of life.
• The findings support the clinical value of dynamic mandibular motion analysis for predictable and efficient implant restorations.
