Summary
Virtual planning and custom 3D-printed bioresorbable scaffolds show promise for maxillofacial reconstruction, offering accurate, biocompatible solutions with good bone formation and implant support.
Area of Science:
- Biomaterials Engineering
- Oral and Maxillofacial Surgery
- Regenerative Medicine
Background:
- Maxillofacial bone defects pose challenges in reconstruction.
- Advancements in virtual planning and 3D printing offer new reconstructive possibilities.
Purpose of the Study:
- To review current advancements in virtual planning and 3D-printed bioresorbable scaffolds for maxillofacial reconstruction.
- To evaluate the clinical outcomes of these technologies.
Main Methods:
- Scoping review of literature up to June 2024.
- Searched PubMed, EMBASE, Web of Science, Scopus, and Cochrane Library.
- Included studies on maxillofacial bone defect reconstruction using virtual planning and 3D-printed bioresorbable scaffolds.
Main Results:
- Thirteen studies were included, assessing scaffold effectiveness in defect reconstruction, bone augmentation, and defect regeneration.
- Scaffolds were generally biocompatible with few adverse events.
- Favorable outcomes included dimensional compatibility, durable support, bone formation, and successful dental implant placement.
Conclusions:
- Custom-made 3D-printed bioresorbable scaffolds, guided by virtual planning, are a promising option for maxillofacial reconstruction.
- These scaffolds offer accuracy, osteoconductivity, and biocompatibility.
- They support bone regeneration and dental implant integration effectively.
