Evaluation of Bioengineered Scaffolds for Mandibular Defect Reconstruction: A Clinical Study

Area of Science:

• Biomaterials science
• Regenerative medicine
• Maxillofacial surgery

Background:

• Mandibular defects pose significant challenges in maxillofacial surgery, necessitating advanced reconstruction techniques.
• Bioengineered scaffolds offer a novel solution by mimicking the natural extracellular matrix to promote bone regeneration.

Purpose of the Study:

• To evaluate the efficacy of bioengineered scaffolds in reconstructing mandibular defects.
• To assess bone regeneration, functional restoration, and complication rates following scaffold implantation.

Main Methods:

• A prospective clinical study involving 30 patients with mandibular defects.
• Treatment with customized hydroxyapatite and collagen scaffolds seeded with autologous mesenchymal stem cells, fabricated using 3D printing.
• Clinical and radiographic assessments at multiple postoperative time points.

Main Results:

• 87% of patients achieved complete defect closure with 76% mean bone regeneration at 12 months.
• Significant improvements in masticatory efficiency and mandibular mobility (70%).
• Minor complications (infection, scaffold displacement) managed conservatively.

Conclusions:

• Bioengineered scaffolds are effective for mandibular reconstruction, yielding high bone regeneration and functional recovery rates.
• The approach demonstrates feasibility and efficacy, supporting further investigation in larger studies.
