Analysis of working-side occlusal contacts
The International Journal of Prosthodontics
|July 1, 1990
Summary
This study analyzed occlusal contacts in healthy adults, finding varied articulation patterns. Canine guidance was more common on the left, while partial group function dominated the right side.
Area of Science:
- Dentistry
- Biomechanics
- Occlusion analysis
Background:
- Understanding occlusal schemes is crucial for dental health and function.
- Variations in articulation patterns can impact masticatory efficiency and temporomandibular joint health.
- Previous research highlights the complexity of occlusal contact distribution.
Purpose of the Study:
- To analyze the frequency and location of occlusal contacts in healthy young adults.
- To identify common articulation patterns in working-side mandibular positions.
- To compare occlusal schemes between the left and right sides of the mandible.
Main Methods:
- Bilateral interocclusal registrations were obtained from 45 healthy young adults.
- Two working-side mandibular positions were recorded for each subject.
- Occlusal contacts were meticulously analyzed based on their frequency and spatial distribution.
Main Results:
- A significant number of subjects exhibited unclassified patterns of articulation.
- In subjects with known occlusal schemes, 'canine guidance' was more prevalent on the left side.
- The most frequent occlusal pattern observed on the right side was 'partial group function.'
Conclusions:
- Occlusal contact patterns in healthy young adults are diverse and often unclassified.
- Asymmetrical distribution of occlusal schemes (canine guidance left vs. partial group function right) is common.
- Further research is needed to understand the clinical implications of these varied occlusal patterns.
