What is Bone Anchorage?

Bone anchorage, also known as skeletal anchorage, provides orthodontists with a precise and temporary system to control difficult tooth movements. These temporary anchorage devices (TADs) are small titanium mini-pinsor plates inserted into the jawbone, serving as a stable anchor while other teeth are adjusted.

This system not only simplifies complex orthodontic movements but also enables movements that would otherwise be impossible, ensuring a smoother and more effective treatment process.

When is Bone Anchorage Necessary?

Bone anchorage devices are often used when:

  • A significant amount of tooth movement is required.
  • Dental anchorage is insufficient, such as in cases of missing teeth or bone loss.
  • Complex orthodontic treatments require extra support to move teeth with precision.

These devices are referred to by several names, including:

  • Mini-plates
  • Micro-implants
  • Micro-screw implants
  • Mini-screws
  • Temporary Anchorage Devices (TADs)

Where Are Bone Anchorage Devices Placed?

Placement varies depending on the movements your orthodontist needs to achieve. Common placement areas include:

  • Cheekbone (Zygomatic Bone)
  • Canine Region of the Lower Jaw: Near the teeth adjacent to your front teeth.
  • Molar Region of the Lower Jaw: In the area near or around the wisdom teeth.

The Surgical Procedure

Your orthodontist has referred you to Dr. Franc Henze, a specialist oral and maxillofacial surgeon, to place the anchorage devices. The procedure involves:

  • Consultation and Planning: Dr. Henze will work with your orthodontist to determine the ideal placement of the devices based on your specific orthodontic needs.
  • Surgical Placement: The devices are typically inserted under local anesthetic or intravenous sedation. In cases where multiple procedures are performed simultaneously, general anesthetic may be used.
  • Post-Surgery Healing: After placement, the devices require a healing period of 3-4 weeks before further orthodontic treatment begins.

What to Expect After Surgery

Dr. Henze will provide you with detailed aftercare instructions to ensure a smooth recovery:

  • Gently rinse your mouth with an antiseptic mouthwash for the first 3-4 days.
  • Use a cotton swab to clean around the bone anchors, avoiding irritation with your tongue or fingers.
  • Avoid chewing or applying pressure near the devices during the healing period.

Benefits of Bone Anchorage

  • Precise Tooth Movement: Allows orthodontists to control tooth adjustments with accuracy.
  • Simplifies Complex Movements: Supports difficult or previously impossible movements.
  • Temporary and Flexible: Devices are removed once orthodontic treatment is complete.
