Changes in chewing patterns after implantation in the edentulous mandible

Area of Science:

• Dentistry
• Biomechanical Engineering
• Prosthodontics

Background:

• Edentulous patients often experience reduced chewing function and quality of life.
• Implant-supported prostheses are known to improve patient outcomes.
• The influence of implant prosthetics on mandibular biomechanics requires further investigation.

Purpose of the Study:

• To compare mandibular border movements and chewing patterns before and after implant-supported overdenture rehabilitation.
• To assess the impact of Dolder-bar and clip-to-bar overdentures on masticatory function.

Main Methods:

• Sirognathograph recordings of mandibular border movements and chewing patterns.
• Measurements were taken in 15 edentulous patients with existing complete dentures.
• Second measurements were performed after rehabilitation with implant-supported Dolder-bar and clip-to-bar overdentures.

Main Results:

• Stabilization with Dolder-bar and clip-to-bar overdentures resulted in improved guidance of mandibular movements.
• Borderline patterns became larger and more harmonic after implant rehabilitation.
• Chewing efficiency was significantly enhanced.

Conclusions:

• Implant-supported overdentures positively influence mandibular border movements and chewing patterns.
• The use of Dolder-bar and clip-to-bar overdentures enhances chewing efficiency and functional outcomes in edentulous patients.
