RESORBABLE MAGNESIUM SHIELD

COMPLETELY RESORBABLE

BUT VOLUME STABLE

REDUCED INVASIVENESS

The fully resorbable SHIELD introduces a pioneering solution for managing buccal and palatal wall defects. Utilizing a flapless approach without the need for membrane fixation, SHIELD can be positioned between the soft tissue and bone, thus providing support to the bone graft material while reinforcing the structural integrity of the augmented site. The approach reduces the need for extensive bone grafting and promotes the preservation of the natural bone contour. By reconstructing alveolar walls, SHIELD minimizes the risk of resorption in the buccal and palatal plates, ultimately enhancing the success of implant procedures.

Mechanically Strong and resorbable

The SHIELD is produced from pure magnesium metal. Magnesium is a biodegradable metal that is resorbed by the human body without toxic residuals. During the degradation process magnesium ions (Mg²⁺) are released. They are a naturally occurring component in the human body and are responsible for many physiological processes. Due to the inherent properties of magnesium metal, the SHIELD provides a mechanically strong yet degradable material option for bone augmentation surgeries.

INDICATIONS

The SHIELD is indicated for guided tissue and bone regeneration (GTR / GBR):

in case of surgical bone defects and bone wall defects
in the context of ridge preservation
in extraction sockets after tooth extractions
in case of GBR in conjunction with immediate or delayed implant placement

PROPERTIES + ADVANTAGES

Thickness: 140 ± 20 μm

Biodegradable metal
Magnesium-based solution
Synthetic and fully resorbable (within 2-4 months)
Volume stable
No removal surgery necessary resulting in fewer surgical interventions and less chair time
Bone Preservation: Maintaining the existing bone structure, reducing the need for extensive bone grafting and complex augmentation procedures.
Ridge Reconstruction: Preservation of the original bone contour and support of both hard and soft tissues regeneration, resulting in a robust and voluminous ridge that can securely accommodate dental implants.
Simplified Procedure & Easy Application: By eliminating the need for flap preparation with additional incisions, fixation, and membrane removal, the surgical process is simplified, making it less invasive for the patient and more efficient for the clinician.

FAQ

WHAT ARE BIODEGRADABLE METALS?

Biodegradable metals are a class of metal that when implanted will gradually degrade and be completely resorbed. The degradation products are then metabolized by the human body.

HOW DOES THE SHIELD DEGRADE?

The SHIELD has a smooth and shiny surface. Immediately upon implantation, the membrane begins to degrade. The degradation process creates a rough surface that improves the adhesion of the soft tissues.

As the magnesium metal degrades, magnesium salts and hydrogen gas are formed at the surface. The combination of the magnesium metal and the magnesium salts provide an effective barrier during the critical healing period. In some instances, hydrogen gas slightly tents the soft tissue above the SHIELD, thereby providing as an additional barrier without affecting bone regeneration.

IS IT NORMAL FOR GAS TO DEVELOP AT THE IMPLANTATION SITE?

During the degradation of the magnesium metal, the metallic structure is transformed into magnesium salts and a small volume of hydrogen gas is released. A small accumulation of the gas may collect around each device and is visible in X-rays. The release of hydrogen gas might present as a slight swelling of the soft tissues.

The magnesium salts keep the original shape and position of the membrane until they are resorbed by the body, whereas the small volume of hydrogen gas initially provides a slight tenting of the soft tissue. Both of these degradation by-products continue to maintain a separation of the soft and hard tissues as a second phase to the barrier functionality of the membrane until they are resorbed by the body.

WHAT SHALL I DO IN CASE OF A DEHISCENCE?

For instances of exposure, it is recommended that special care is taken for controlling oral hygiene, rinsing the area with e.g. CHX solutions, and avoiding acidic food and/or drink as well as smoking. No additional treatment measures for the soft tissue is required. Cases of small dehiscence should disappear after 2-3 weeks. There is no need for membrane removal in the case of localized exposure.

Upon exposure, the membrane can appear dark grey/ black in colour, which happens normally during the degradation process.
