Magnesium in der Zahnmedizin

Die Knochenregeneration neu definieren

Nach einer Zahnextraktion wird das natürliche Knochengerüst im bukkalen und palatinalen Bereich stark umgebaut, was zu einer beschleunigten Knochenresorption führt1. Dies kann zu einem Kieferkammkollaps, einer Rezession des Weichgewebes und einer beeinträchtigten Implantatinsertion führen, was das Risiko langfristiger funktioneller und ästhetischer Komplikationen erhöht2.

Die Shield-Technik mit dem vollständig resorbierbaren Magnesium NOVAMag® SHIELD vereinfacht nicht nur die Behandlung von Zahnextraktionsdefekten, sondern erhält auch das Knochenvolumen und schafft so eine stabile Grundlage für den langfristigen prothetischen Erfolg3.

Tooth extraction leads to natural bone resorption over time, compromising stability for future restorations4. When replacing missing teeth with a dental bridge or implant, proper support is essential for long-term function and aesthetics. Without adequate bone preservation after tooth extraction, natural bone loss can impact the fit and durability of the restoration5.

NOVAMag® SHIELD
The ultimate solution for bone defect and bridge aesthetics

Die Shield-Technik zielt darauf ab, die Resorption des bukkalen/palatinalen Alveolarknochens nach der Extraktion zu verhindern. Die Anwendung von NOVAMag® SHIELD gewährleistet den Erhalt des Knochenvolumens und schafft so eine stabile Grundlage für den langfristigen prothetischen Erfolg6. Im Gegensatz zu den traditionellen Ansätzen, bei denen der regenerierte Knochen im Laufe der Zeit resorbiert werden kann, fördert NOVAMag® SHIELD die Bildung eines starken und gesunden Knochens für die Implantat- oder Brückeninsertion3.

The Shield Technique

The ultimate solution for bone defect and bridge aesthetics – CLINICAL SNAPSHOTS

NOVAMag® SHIELD

By combining magnesium’s unique properties with strong mechanical stability,
NOVAMag® SHIELD provides a minimally invasive solution that enhances treatment outcomes and improves patient comfort.

“The NOVAMag® SHIELD Technique is the easiest way to rebuild the buccal plate at the time of extraction.”

Dr. Giorgio Tabanella Periodontist, Italy

Die wichtigsten Merkmale von NOVAMag® Shield

  • Biodegradability: No need for a second surgical procedure to remove the membrane.
  • Biocompatibility: Naturally integrates with the body.
  • Bone Regeneration Support: Maintains space for bone growth and enhances optimal bone healing and regeneration.
  • Barrier function: Prevents soft tissue infiltration into the healing site.
  • Easy Handling: The membrane is strong and ductile, allowing for easy
    adaptation to complex defects.

Clinical Applications

The Shield Technique is an ideal solution for various clinical situations that require bone regeneration and tissue healing.
  • Thin or compromised bone walls
  • Missing bone after extraction
  • Socket Management & Bridge Aesthetics
  •  Immediate or Delayed Implant Placement
  • Ridge reconstruction

Faq

The SHIELD technique is ideal for:

  • Cases with thin or compromised bone walls
  • Socket preservation after tooth extraction
  • Immediate or delayed implant placement
  • Ridge augmentation for implant site preparation
  • Preserving natural bone contours in the anterior aesthetic zone

Yes, the Shield Technique is effective for immediate implant placement. By stabilizing the surrounding bone and preventing resorption, it ensures a more predictable healing process and long-term implant success.

NOVAMag® SHIELD is specifically designed for the Shield Technique because of its:

  • Biocompatibility – Magnesium naturally integrates with bone.
  • Mechanical Strength – Provides stability during initial healing.
  • Resorbability – Eliminates the need for a second surgery.
  • Bone Regeneration Support – Enhances bone healing by preventing soft tissue infiltration.

Yes, NOVAMag® SHIELD is compatible with various bone grafts, including autografts, allografts, and xenografts. It helps stabilize the graft material while preventing soft tissue ingrowth.

Magnesium exhibits unique properties, such as:

  • Biodegradable metal without immune reactions
  • Mechanical strength for stability
  • No removal necessary resulting in fewer surgical interventions 
  • Synthetic alternative
