Hypothesis
There is no consensus on the material model for the mandible that realistically estimates the Young's modulus of the bone.
Conclusion
The review identifies 12 distinct heterogeneous material models for finite element analysis of the human mandible and highlights the need for standardization in future research.
Supporting Evidence
- 12 material models for finite element analysis of human mandible are identified.
- Diversity in material models is highlighted and risk of bias for each is assessed.
- Recommendations for selecting density-modulus relationships are given.
- Future directions include standard protocols and validation methods.
Takeaway
This study looks at different ways to model the human jawbone for better accuracy in medical simulations, finding many different methods but no clear best one.
Methodology
A systematic review using PRISMA guidelines was conducted on finite element studies of the mandible, analyzing 77 studies to identify material models and assess their risk of bias.
Potential Biases
The original studies were characterized with a low to medium risk of bias.
Limitations
The review may have missed some material models due to inaccessible reports and did not specifically target the material models themselves.
