NICO / FDOK Treatment in Zurich: Resolving Chronic Jawbone Inflammation

NICO occurs when chronic inflammatory processes alter the inner architecture of the jawbone. Due to poor blood circulation, localized sections of the bone do not receive adequate nutrients, leading to a painless die-off (necrosis) and gradual resorption of the bone tissue.

This process creates hollow cavitations inside the jaw, which typically become filled with a soft, greasy, fatty-degenerative tissue matrix. This is why specialists use the term Fatty-Degenerative Osteonecrosis of the Jawbone (FDOK). Because it acts as a "silent inflammation" without acute local swelling or pus, it constantly impacts the immune system and can severely degrade your long-term general well-being.

Common Triggers & Causes

• Incomplete Extraction Healing: Frequently occurs when a socket does not heal properly after a tooth extraction—most commonly after wisdom tooth removal.
• Surgical Remnants: Retained foreign objects, root fragments, or residual tooth germs left behind in the bone.
• Compromised Healing Factors: Prior oral surgeries combined with external systemic influences or nutritional deficiencies.

Potential Symptoms

While some patients experience localized jaw pain or swelling, NICO often acts as a silent inflammation. Systemic companion symptoms are highly diverse and unique to each individual, including:

• Unspecified systemic physical complaints or chronic joint pain.
• Chronic headaches, atypical facial pain, or neuralgia-like jaw pain.
• Persistent fatigue, exhaustion, and a general lack of energy.
• Interferences with thyroid function or chronic inflammatory disorders.

Resolving NICO requires a meticulous, specialized surgical approach to ensure complete eradication of the degenerative tissue and a predictable biological recovery:

1. 3D CBCT Diagnostics

Conventional 2D dental X-rays (panoramic radiographs) provide limited visibility of the inner bone density. Therefore, if NICO is suspected, we utilize high-resolution 3D Cone Beam Computed Tomography (CBCT / DVT). This gives us a highly detailed view of your internal bone structure to confirm the diagnosis and map out a precise surgical guide.

2. Surgical Debridement

Under comfortable local anesthesia, a minor, minimally invasive oral surgery is performed to access the site. The diseased, fatty-degenerative, and non-vital tissue matrix is thoroughly curretted and completely removed from the bone cavity.

3. Medical Ozone Disinfection

Following debridement, the open bone cavitation is treated with state-of-the-art ozone therapy. Ozone gas deeply sanitizes the treated area, eliminating residual pathogens, bacteria, and germs gently and effectively without harming healthy bone cells.

4. PRF Platelet-Rich Fibrin Acceleration

To maximize biological wound healing, we use PRF membranes. Prior to surgery, a small sample of your own blood is drawn and centrifuged to concentrate regenerative growth factors and platelets. This autologous PRF membrane is placed directly into the bone cavity right before suturing, dramatically accelerating natural bone regeneration and soft tissue healing.

5. Biological Bone Grafting (Optional)

Once the site is fully healed and stable, a targeted bone augmentation using biocompatible materials can be performed if clinically necessary to restore the jaw’s original structural volume.
