|November 1, 1975
Summary
This study measured the dynamic properties of six maxillofacial materials, including dynamic modulus and resilience, across a temperature range. Findings provide crucial data for material selection in dental and medical applications.
Area of Science:
- Biomaterials science
- Materials engineering
- Mechanical engineering
Background:
- Maxillofacial materials are crucial for reconstructive surgery and prosthetics.
- Understanding their dynamic mechanical properties is essential for predicting performance and longevity.
- Limited data exists on the dynamic behavior of commonly used maxillofacial materials under varying temperatures.
Purpose of the Study:
- To evaluate the dynamic properties of six different maxillofacial materials.
- To determine the dynamic modulus, internal friction, and dynamic resilience of these materials.
- To analyze how temperature variations affect these dynamic properties.
Main Methods:
- Six distinct maxillofacial materials were selected for analysis.
- A Goodyear Vibrotester was employed to measure dynamic properties.
- Measurements were conducted across a temperature spectrum from -15 to 37 degrees Celsius.
Main Results:
- The dynamic modulus varied significantly, ranging from 11.1 to 124.8 kg/cm².
- Dynamic resilience showed a broad spectrum, from 1.1% to 63.5%.
- Internal friction data was also collected but not detailed in the abstract.
Conclusions:
- The evaluated maxillofacial materials exhibit a wide range of dynamic mechanical responses.
- Temperature influences the dynamic properties of these materials, impacting their suitability for clinical use.
- This research provides valuable data for selecting appropriate maxillofacial materials based on expected environmental conditions and performance requirements.
