[Movement pattern of the orofacial soft tissues during mastication]
Deutsche Zahnarztliche Zeitschrift
|December 1, 1979
Summary
Researchers identified four distinct masticatory movement patterns in orofacial soft tissues. Lip movement analysis revealed specific vertical and width changes during chewing cycles.
Area of Science:
- Biomechanics
- Orofacial Dynamics
- Dental Science
Context:
- Understanding masticatory movements is crucial for dental and prosthetic applications.
- Previous research has not fully characterized the dynamic orofacial soft tissue patterns during chewing.
Purpose:
- To establish and define characteristic orofacial soft tissue movement patterns during mastication.
- To quantify lip vertical movement and width reduction during the masticatory cycle.
Summary:
- Analysis of video recordings identified unique orofacial soft tissue movement patterns.
- Four fundamental patterns of masticatory movements were established.
- Average vertical lip movement was 7.6 mm, with width reduction of approximately 13% at the cycle's start and 8.5% at the end.
Impact:
- Provides a quantitative basis for understanding orofacial biomechanics during chewing.
- Informs the design of dental prosthetics and treatments for orofacial disorders.
- Enhances knowledge of normal masticatory function for clinical applications.
