Magnesium in dentistry

Redefining bone regeneration

Following tooth extraction, the natural bone support in the buccal and palatal region undergoes significant remodelling leading to accelerated bone resorption1. This can result in ridge collapse, soft tissue recession, and compromised implant placement, increasing the risk of long-term functional and aesthetic complications2.

The Shield Technique with the fully resorbable magnesium NOVAMag® SHIELD not only simplifies the treatment of tooth extraction defects but also preserves bone volume, creating a stable foundation for long-term prosthetic success3.

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

The Shield Technique aims to prevent post-extraction resorption of the buccal/palatal alveolar bone. The application of NOVAMag® SHIELD ensures the preservation of bone volume, creating a stable foundation for long-term prosthetic success6. Unlike the traditional approaches, where regenerated bone may resorb over time, NOVAMag® SHIELD promotes the formation of a strong and healthy bone for implant or bridge placement3.

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

Key Features of 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

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
