Bone Grafting

Dr. Nik Vourakis brings years of specialised experience in managing complex bone grafting procedures, offering an extensive range of services for both minor and major bone augmentations.

His proficiency in bone regeneration is ideal for cases that require precise, predictable, and reliable outcomes. His key areas of expertise include:

  • Extraction Socket Management: Utilizing advanced techniques to preserve bone following tooth extraction, preventing resorption and optimizing the site for future implant placement.

  • Minor Bone Augmentation: Addressing localized bone deficiencies using grafting methods to provide adequate bone volume for implant positioning in compromised sites.

  • Major Bone Augmentation: Restoring significant bone deficits through a combination of grafting techniques that allow for implant placement in areas with severe resorption.

  • Sinus Floor Elevation: Employing sinus lift procedures to elevate the floor of the maxillary sinus and increase bone height, enabling successful posterior implant placement in cases of sinus pneumatization or insufficient bone.

  • Vertical and Horizontal Bone Grafting in Severe Atrophy: Managing complex cases of severe bone resorption using advanced vertical and horizontal bone grafting techniques to restore both the height and width of the alveolar ridge.

Clinical Techniques & Approaches?

He employs advanced, evidence-based techniques to achieve optimal clinical outcomes he primarily uses Guided Bone Regeneration (GBR), which is highly effective for addressing more complex cases. GBR uses barrier membranes to create an environment conducive to new bone growth. The four pillars of successful GBR - stability, angiogenesis, space maintenance, and tension-free primary closure - guide his approach. While he prefers autogenous bone due to its osteogenic, osteoinductive, and osteoconductive properties, he also uses allografts, xenografts, and synthetic materials when additional volume or structural support is required.

For more challenging augmentation cases, he employs advanced techniques such as the Sausage Technique and the Khoury Plate Method. The Sausage Technique, introduced by Dr. Istvan Urban (2017), is ideal for both horizontal and vertical augmentation, particularly in the molar regions where bone is often thin. This technique involves securing a membrane over the bone graft using pins and screws, creating a "sausage" effect that stabilises the graft.

For vertical defects, the Khoury Plate Method is often his technique of choice. This involves harvesting a bone block from the ramus or chin, splitting it into thin plates, and securing it with titanium screws. The technique is particularly effective for large vertical defects and requires significant experience to execute successfully.

Bone Graft Materials

  • Choosing the Right Graft

    Understanding the biological and clinical implications of various graft materials is essential for selecting the optimal solution for each patient. Dr. Nik Vourakis utilizes a variety of graft materials based on specific clinical indications:

  • Autograft (Patient’s Own Bone)

    Often considered the gold standard, autografts contain living osteocytes, growth factors, and marrow cells, which enhance the regenerative potential of the graft. These grafts offer superior integration and are typically used for critical augmentation areas where rapid and predictable healing is required.

  • Allograft (Donor Bone)

    When autografts are not viable, allografts provide an excellent alternative. Allografts are harvested from human cadaveric donors and processed to remove antigens, minimizing the risk of rejection. These grafts are used when the patient’s own bone is insufficient, and they offer reliable results in ridge augmentation and sinus lift procedures.

  • Xenograft (Bovine Bone)

    Xenografts are derived from animal bone (typically bovine) and serve as a scaffold for new bone growth. These grafts are particularly useful when a larger volume of bone is needed, and they provide long-term stability due to their predictable resorption rate and excellent biocompatibility.

Biological Considerations for Optimal Bone Regeneration

Bone grafting is inherently complex, and the biological factors involved must be carefully considered to achieve optimal outcomes. He ensures each graft material is selected based on the patient’s individual needs, accounting for factors such as:

  • Blood Supply: Adequate blood flow to the graft site is critical for the healing process. He assesses the blood supply to the recipient site to determine the best approach for grafting and to minimize complications such as graft failure or resorption.

  • Bone Quality and Volume: The quality and quantity of available bone play a crucial role in the selection of the grafting technique and material. For patients with insufficient bone volume, vertical and horizontal bone grafting procedures are employed to restore adequate dimensions for implant placement.

  • Host Site Health: The health of the surrounding tissues, including soft tissue integrity and underlying bone structure, is also evaluated to ensure the graft integrates properly and remains stable throughout the healing process.
