Summary
A new tooth-supported module improves guided bone regeneration accuracy using titanium mesh. This technique enhances bone augmentation precision for better dental implant and denture outcomes.
Area of Science:
- Dentistry
- Biomaterials Engineering
- Regenerative Medicine
Background:
- Guided bone regeneration (GBR) with titanium mesh is standard for bone augmentation.
- Titanium mesh placement can suffer from deformation and sliding, compromising augmentation accuracy.
Purpose of the Study:
- To introduce a novel tooth-supported titanium mesh bending and positioning module.
- To enhance the precision of bone augmentation procedures.
Main Methods:
- Digital design of ideal bone increment volume.
- 3D printing of a custom module to guide titanium mesh bending and placement.
- Utilizing adjacent teeth for module support and positioning.
Main Results:
- Preliminary favorable outcomes in three cases.
- Average vertical bone gain of 4.16 mm and horizontal gain of 7.48 mm after 6 months.
- Maximum deviation of 1.5 mm, with a mean deviation of 0.6 mm, demonstrating improved accuracy.
Conclusions:
- The tooth-supported module significantly improves the accuracy of titanium mesh-based bone augmentation.
- This technique offers a more precise and reliable method for bone augmentation, facilitating subsequent dental implant and denture procedures.
