Summary
Rapid prototyping can create realistic synthetic mandibles with controlled asymmetry. This method aids future research into craniofacial surgery and mandibular symmetry evaluation.
Area of Science:
- Biomedical Engineering
- Oral and Maxillofacial Surgery
- Anatomical Modeling
Background:
- Rapid prototyping (RP) is a valuable tool in craniofacial surgery for creating prostheses and surgical guides.
- Accurate anatomical models are crucial for research and surgical planning.
Purpose of the Study:
- To develop and describe a methodology for fabricating asymmetric human mandibles using RP.
- To create experimental models for evaluating mandibular symmetries.
Main Methods:
- Stereolithography was used to produce synthetic mandible models with controlled asymmetry.
- A detailed method was defined for model preparation, landmark description, and fabrication.
- Synthetic mandibles were accurately produced from scanned human data and coated for landmarking.
Main Results:
- A series of synthetic mandibles with varying degrees of asymmetry were successfully fabricated.
- The methodology allowed for precise control over asymmetry in the condylar neck, ramus, and body.
- A reproducible experimental model for image acquisition was designed.
Conclusions:
- Stereolithography is a viable method for producing synthetic skeletal models with precise, known asymmetries.
- This technique provides a valuable tool for research in craniofacial surgery and biomechanics.
