creos xenoprotect - a natural collagen membrane

Experience the resorbable collagen membrane with outstanding handling properties

Collagen membrane

creos xenoprotect is a resorbable dental membrane. A resorbable collagen membrane is used for guided bone regeneration (GBR) and guided tissue regeneration (GTR) procedures. 

It's composed of a network of interwoven, highly purified porcine collagen and elastin fibers, providing the membrane with high mechanical strength.

The fiber mesh holds the bone graft material securely in place, preventing undesired soft tissue from migrating into the bone augmentation site during bone healing.

Why creos xenoprotect?

Outstanding handling properties

A noticeable difference when applying the creos xenoprotect membrane is the ease of repositioning and unfolding as it doesn't become sticky when hydrated. It's rehydrated within seconds and adheres well to the defect shape. What's more, the membrane can be cut and pre-shaped according to the specific defect without having to consider any major size increase when moistened.1  

Easy to stretch and suture

creos xenoprotect is highly tear resistant due to its high mechanical strength, and its elastin fibers make the membrane stretchable.2 This makes it easy to stretch over the defect area and suture without fear of rupturing the membrane.

Prior to GBR, the mean defect size was 4.4 ± 2.6 mm wide and 13.1 ± 2.6 mm high. Eight months after treatment the bone gain was 4.0 mm (56.9 %) and 4.7 mm (51.0 %) in width when measured 1 mm and 3 mm from the top of the crest, respectively. (5)

Designed to perform

In clinical studies, creos xenoprotect demonstrates good results in the treatment of dehiscence defects3 and in horizontal ridge augmentation procedures.4,5 In both applications, creos xenoprotect facilitates bone gain and supports successful implant placement.3,4,6

In preclinical studies, creos xenoprotect has been shown to play an active role in regulating bone-healing dynamics in vivo.7 In addition, as a natural collagen membrane that is not subjected to chemical cross-linking, creos xenoprotect exhibits an enduring resistance to degradation in vivo.2

Low surface expansion when hydrated. (1)

Low rates of complications

In clinical studies in patients with dehisced implant sites and horizontal bone defects, use of creos xenoprotect is associated with favorable healing with no major complications.3,4,5 Observed rates of wound dehiscence and membrane exposure are low when creos xenoprotect is used in guided bone regeneration.3,4,5

Three sizes - limited waste

Whether larger bone augmentations or smaller periodontal defects, the optimal fit can be found without extensive trimming. This limits waste and minimizes costs for you and your patients. creos xenoprotect is available in three different sizes: 15 x 20 mm, 25 x 30 mm and 30 x 40 mm.

Dr. Fabrice Clipet, France – Augmentation after immediate implant placement

Situation: 7 mm buccal probing and mild root resorption at upper central incisor (tooth #21).

Dr. Bastian Wessing, Germany – Horizontal and vertical ridge augmentation of a knife-edge ridge

Situation: Missing teeth 46, 47. Late implant placement, bone quality D1, poor bone quantity.

Solution: Horizontal and vertical augmentation by GBR using creos xenoprotect collagen membrane with “tenting screw technique”.

Prof. Dr. Mariano Sanz, Spain – Extraction socket preservation

Situation: Periapical infection and an open fistulous track toward the root of upper central incisor (tooth #21). Presence of a perio-endo lesion and tooth is extracted. Loss of the buccal bone plate so a lateral bone augmentation procedure is indicated.

Solution: Deproteinized bovine bone mineral (DBBM) is used as scaffold and creos xenoprotect as a protective barrier. An implant is placed after six months of uneventful healing.

Dr. Oscar Gonzalez-Martin, Spain – Extraction socket preservation

Situation: Fractured first maxillary left premolar, tooth extraction indicated.  

Solution: GBR procedure and delayed implant placement.

View case (PDF, 442 kB)

Dr. Javier Alandez, Spain – Extraction socket preservation

Situation: Fractured first maxillary left premolar, tooth extraction indicated. 

Solution: The defect is filled by using bovine hydroxyapatite. A creos xenoprotect collagen membrane is applied to cover the defect. After three months, reopening of the treated area shows complete regeneration of the initial defect.

“I really like the handling of the material. The fact that it doesn’t lose its shape when you place it, is a great benefit. It gives you the possibility to take out the membrane and trim it. After a minute or so, when it is soaked, it attaches very nicely to the bone surface and no fixation seems to be necessary.”

Dr. Ramón Buenechea, Spain

Dr. Ramón Buenechea, Spain

“It is a thin, easy to handle and quickly moistened membrane that maintains its properties as a barrier. It allows suturing and/or tag fixation and is easily adapted to the bone defect.”

“For over a decade I have used collagen membranes to achieve excellent results.  Each type of membrane offered varying benefits. Nobel Biocare has managed to integrate most of them. I was surprised by its rapid and uniform hydration. It is easy to cut and it does not fold itself together. It is ideal for maxillary sinus lift and bone regeneration.”

Dr. Ali Tahmaseb, Netherlands

“I like the membrane because it's very easy to handle compared to other membranes I’ve used. The most important thing for me is the extended resorption time – the membrane stays in place longer.”

“We have better results with creos xenoprotect than with the membranes we have used before. What I like is that the handling is very easy. The mechanical stability is very high and when it is rehydrated it adapts very well to the underlying bone.”

Dr. Bastian Wessing, Germany

Dr. Michael Danesh-Meyer, New Zealand

“My early experience with this membrane, both intra-operatively and post-operatively, has been positive. Post-operatively, I like the fact that I see very little inflammation. 10 days post suture removal, the tissues are looking pink. If you're using GBR in conjunction with your implant therapies, I would recommend this membrane."

“I was pleasantly surprised to still find remnants of the creos xenoprotect membrane after six months. This long degradation time provides a greater chance of success.”
