Bioengineering of Periodontal Tissues: Cell Therapy and Biomaterials Application.

Area of Science:

• Oral bioengineering
• Tissue regeneration
• Biomaterials science

Background:

• Periodontal regeneration is challenging due to complex tissue structure and disease-induced inflammation.
• Conventional therapies often fail to fully restore bone, ligament, and cementum.
• Cell-based and biomaterial-assisted strategies are emerging as promising alternatives.

Purpose of the Study:

• To review current advances in cellular technologies for periodontal regeneration.
• To emphasize biological rationale, material design, and delivery methods for next-generation treatments.
• To analyze progress in hydrogel systems, microspheres, decellularized matrices, and 3D bioprinting.

Main Methods:

• Review of stem-cell-based strategies (periodontal ligament, dental pulp, mesenchymal stem cells).
• Analysis of engineered scaffolds, hydrogels, microspheres, and decellularized matrices.
• Evaluation of 3D bioprinting, gene-modified cells, and emerging delivery techniques.

Main Results:

• Stem cells enhance periodontal regeneration through paracrine and immunomodulatory effects.
• Engineered scaffolds, biomaterials, and 3D bioprinting enable multi-tissue regeneration.
• Advanced delivery and biofabrication techniques are crucial for clinical translation.

Conclusions:

• Periodontal bioengineering is a rapidly advancing field with significant potential.
• The convergence of bioprinting, immune-responsive biomaterials, and personalized cellular constructs is key.
• Functional restoration of diseased oral tissues is a strong prospect for future treatments.
