BIO-OSS, a bovine bone substitute, effectively fills bone defects and reconstructs ridges. Long-term studies show no resorption, indicating durable results for bone augmentation.

Area of Science:

  • Biomaterials Science
  • Oral and Maxillofacial Surgery
  • Regenerative Medicine

Background:

  • Bone defects and ridge configurations require effective reconstruction.
  • BIO-OSS is an allergen-free bone substitute of bovine origin.
  • Assessing the long-term efficacy and stability of bone substitutes is crucial.

Purpose of the Study:

  • To evaluate the clinical and radiological outcomes of BIO-OSS implantations.
  • To assess the healing process and long-term stability of BIO-OSS in bone defects.
  • To investigate the potential for bone ingrowth and resorption of BIO-OSS.

Main Methods:

  • Seventy-one patients received 126 BIO-OSS implantations for bone defects.
  • Defect size was measured, and healing was assessed.

  • Radiological (X-ray) and histological (bone biopsies) evaluations were performed.
  • Clinical signs of resorption were monitored.

    • Main Results:

    • Defect size significantly influenced healing outcomes.
    • BIO-OSS areas showed higher density than control sites on X-ray.
    • Histological analysis confirmed bone ingrowth into the BIO-OSS scaffold.
    • No clinical signs of BIO-OSS resorption were observed, even after 6 years.

    Conclusions:

    • BIO-OSS demonstrates excellent integration and stability in bone defects.
    • The material promotes new bone formation and maintains augmented form over time.
    • BIO-OSS is a durable and effective option for bone reconstruction and augmentation.
