Summary
This study reveals significant regional differences in human maxilla bone properties. Alveolar bone is thicker and less stiff, while body bone is thinner and stiffer, impacting biomechanical models.
Area of Science:
- Biomechanical Engineering
- Orthodontics
- Dental Materials Science
Background:
- Understanding regional material properties of the human maxilla is crucial for accurate biomechanical modeling.
- Previous studies have indicated variability, but detailed regional analysis of elastic properties and stiffness orientation is lacking.
Purpose of the Study:
- To investigate the regional variations in cortical bone material properties within the adult human dentate maxilla.
- To characterize differences in thickness, density, elastic properties, and stiffness direction across various maxillary sites.
Main Methods:
- Cortical bone samples were harvested from 15 distinct sites in 15 fresh-frozen adult human maxillas.
- Measurements included cortical thickness, density, elastic properties, and the principal axes of stiffness.
Main Results:
- Alveolar bone regions exhibited greater thickness, lower density, and reduced stiffness compared to the maxillary body.
- The maxillary body showed thinner, denser, and stiffer cortical bone.
- Palatal bone properties were intermediate, more closely resembling alveolar bone.
- Significant regional variation in the orientation of principal stiffness axes was observed, with consistency noted in the alveolar area and frontomaxillary pillar.
Conclusions:
- The human maxilla displays significant regional heterogeneity in its material and elastic properties, particularly in stiffness orientation.
- These findings suggest greater variability than previously reported for the mandible.
- Accurate finite-element models of the maxilla require the incorporation of this detailed regional property data for improved reliability.

01:17Mortar Properties
Mortar properties encompass a range of characteristics crucial for construction and masonry work, including workability, water retention, bond strength, durability, compressive strength, volume change, and appearance. Workability refers to mortar's ability to be easily applied and manipulated without sagging or falling off surfaces, which is important for efficient masonry unit placement and alignment. Water retention is essential to prevent the mortar from losing moisture too quickly to the...
01:29Bone Formation by Intramembranous Ossification
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...
