Tisseos® is a bi-layered, synthetic, biocompatible and fully resorbable membrane for
Guided Bone Regeneration (GBR) and Guided Tissue Regeneration (GTR) applications.
Bilayered structure for optimal barrier effect
Specially designed bilayered structure prevents (gingival) epithelial tissue ingrowth on one side
(smooth fascia of dense layer) while promoting cell infiltration and guided bone healing on the other
(matt fascia with non-woven microfibers).
BILAYERED STRUCTURE
Next generation synthetic resorbable membrane
SYNTHETIC
Synthetic – today’s alternative choice:
• Medical-grade Polylactic-Glycolic Acid provides excellent
biocompatibility. A 100% biodegradable polymer, PLGA has a long
history of successful use in a variety of medical applications and
devices such as resorbable sutures, pins, screws etc, and over
many decades
• Unlike bovine or porcine derived membranes, Tisseos® is free
from animal derivatives. Our biocompatible synthetic membrane
avoids the risk of transmission of animal pathogens.
• Widens treatable patient group: Tisseos® synthetic membranes
are suitable for patients who avoid animal by-products for
cultural reasons or lifestyle choices.

Optimal bone and tissue regeneration are both guaranteed thanks to
the slow, fully controlled resorption over 6 months, avoiding any

Key benefits of Tisseos®
•
A major advantage of Tisseos® is its easy surgical
handling when compared to collagen membranes.
When placed on the bone, the microfibre layer
soaks up the blood and it attaches easily to the
bone.
•
The membrane can easily be repositioned on the
bone defect for optimal placement to cover the
biomaterial.
•
When suturing, the dense layer (smooth side of the
membrane) slides easily over the gingival tissue
without disturbing the bone filling biomaterial.

Both the dental surgeon and the patient benefit
from shorter surgical times and improved

(prior to implantation)
Alveolar bone resorption after tooth extraction cannot
be avoided. In the anterior maxillary bone, resorption is
observed on the vestibular side and can negatively
impact the placement of the implant in two ways:
•
The axis of the dental implant may be misplaced
•
The implant may be visible when smiling
Using a dental membrane allows you to overcome such
problems.

way.

Socket preservation
•
After tooth extaction, the alveolar bone resorbs,
compromising the insertion of implants.
•
Filling of the alveole with biomaterial limits the
bone resorption.
•
Tisseos® membrane covers the biomaterial until
bone healing is complete.

•
The insertion of a dental implant for a screwretained prosthetic may lead to a vestibular
dehiscence when the maxillary bone profile is not
favorable.
•
The use of Tisseos® and a biomaterial at the apex of
the implant allows you to prevent such dehiscence.
•
The ease of handling of Tisseos® saves time in such
types of surgery.

What to do in case of
membrane exposure?
•
When filling a large defect, it may be difficult to close the
gingival tissue without tension. The membrane may then
become exposed during the gingival healing.
•
If exposed, Tisseos® membrane maintains its physical
integrity, prevents leakage of the biomaterial and
prevents infection of the site.
•
The healing of the gingiva is favoured by the guided
tissue regeneration properties of the Tisseos®
membrane.
•
After exposure, the gingival tissue will heal and close in
2 weeks without losing the barrier effect.
•
Mouth wash with antiseptic solution and local application
of a Chlorhexidine gel are recommended in case of
membrane exposure.
