Alveolar Bone Augmentation Using Octacalcium Phosphate and Collagen Composite with Custom-Made Titanium Mesh: A Case...

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Oral and Maxillofacial Surgery

Background:

• Autologous bone grafts are superior for bone regeneration but challenging for extensive augmentation.
• Octacalcium phosphate (OCP) and its collagen composite (OCP/Col) demonstrate enhanced bone substitute capabilities.
• Alveolar bone defects often require advanced augmentation techniques for successful dental implant restoration.

Purpose of the Study:

• To report the first clinical application of OCP/Col combined with a custom titanium mesh for extensive alveolar bone augmentation.
• To demonstrate the efficacy of this combination in reconstructing maxillary anterior alveolar bone defects.
• To restore occlusion and aesthetics using dental implants following bone augmentation.

Main Methods:

• A custom titanium mesh was designed based on preoperative simulations for ideal alveolar morphology.
• Extensive alveolar bone augmentation was performed using OCP/Col and the custom titanium mesh.
• Dental implants were placed six months post-augmentation, followed by prosthesis insertion.

Main Results:

• Ideal alveolar morphology was reconstructed six months after bone augmentation with OCP/Col and titanium mesh.
• Successful placement of dental implants and restoration of occlusion and aesthetics were achieved.
• The patient experienced significant improvement in quality of life post-treatment.

Conclusions:

• OCP/Col combined with a custom titanium mesh is effective for reconstructing extensive alveolar bone defects.
• This approach offers a viable solution for challenging cases requiring significant bone augmentation in the maxillary anterior region.
• The successful outcome highlights the potential of OCP/Col as a bone substitute in combination with rigid fixation for complex reconstructive procedures.
