Bone grafting in maxillofacial trauma

Area of Science:

• Oral and Maxillofacial Surgery
• Regenerative Medicine
• Biomaterials Science

Background:

• Maxillofacial trauma management involves complex reconstructions.
• Technological advancements are transforming surgical planning and execution.
• The COVID-19 pandemic influenced treatment approaches, favoring conservative methods.

Purpose of the Study:

• To review current grafting strategies for maxillofacial trauma.
• To explore recent technological advancements impacting trauma management.
• To summarize the evolving landscape of reconstructive options.

Main Methods:

• Literature review of recent advancements in maxillofacial trauma grafting.
• Analysis of technological applications including 3D imaging, printing, and bioprinting.
• Examination of stem cell and growth factor research in the field.

Main Results:

• 3D imaging and navigation systems enhance preoperative and intraoperative planning.
• 3D, 4D, and 5D bioprinting show promise for complex reconstructions.
• Stem cells and growth factors are key research areas; trauma incidence decreased during COVID-19.
• Autogenous grafts are preferred, with vascularized flaps for extensive defects.

Conclusions:

• Preoperative planning is critical for successful maxillofacial trauma reconstruction.
• Early bone and soft tissue reconstruction is recommended for severe traumas.
• Autogenous grafts are the standard; alloplastic or xenografts are alternatives when autografts are unavailable.
