Geistlich Bio-Oss® Collagen

A natural bone and collagen substitute that maintains long-term stability, volume and enhances new bone formation.

The Bio-Oss® Collagen block is flexible and easy to mould into position.


Geistlich Bio-Gide®

A collagen membrane for reliable bone regeneration and optimal tissue integration.

The natural collagen structure of Geistlich Bio-Gide® permits prompt and homogeneous vascularisation and so brings about optimal tissue integration and wound stabilisation.


What are the benefits?

Flexible and easy to use

Flexible and easy to use.

Geistlich Bio-Oss® collagen and Bio-Gide® can be efficiently moulded to fit any gap, straight out of the packet.

Immediate implant placement

Ideal for immediate implant placements.

With Geistlich materials you can successfully fill the gap there and then, saving you and your patient valuable time.

* Reference 8.
Long-lasting stability

Long-lasting stability.

Our collagen block is incredibly porous, which maximises blood flow and bone formation to promote long-term stability for the ridge.

* References 1-8.
Resorption rate

Minimal resorption rate.

Bio-Oss® Collagen has minimal resorption rates compared to our competitors meaning results are stronger for longer.

* References 1-8.
Biomaterial you can trust

"The GBR technique with the combination of autologous bone chips, Geistlich Bio-Oss® and Geistlich Bio-Gide® offers predictable outcomes for contour augmentation. It's important that the products are both clinically and scientifically well documented."

Prof. Daniel Buser/ Switzerland

"The 10% collagen component probably supports stabilization of the blood coagulum and keeps the Geistlich Bio-Oss® particles together."

Prof. Ronald Jung PhD / Switzerland

"Geistlich Bio-Oss® Collagen 50mg was the ideal size graft material for placement between the implant and facial plate for maintaining the hard and soft-tissue volume throughout the course of osseointegration and healing."

Dr. Justin Kang / USA

"Geistlich Bio-Oss® Collagen can effectively offset the bone resorption pattern that naturally occurs following tooth extraction, which as we know can hamper esthetics and lead to soft-tissue instability."

Prof. Robert C. da Silva / Brazil

Clinical Cases

PD Dr. Markus Schlee / Germany

Clinical Challenge: The torn, perforated buccal bone lamella is very thin due to the horizontal absorption distally and the angulation of the tooth occurring as a result of the extraction.

Aim/Approach: Preserving the extraction socket and alveolar ridge volume in immediate implant placement and simultaneous bone augmentation with Geistlich Bio-Oss®.

Conclusion: Augmentation with Geistlich Bio-Oss® enabled the ridge volume and the esthetics to be preserved

Dr. Uleil Grunder / Switzerland

Clinical Challenge: The upper premolar had to be removed due to an advanced periodontal disease and severe bone loss around the infected tooth. The bone defect was an intra-alveolar defect without dehiscence or fenestration.

Aim/Approach: An early implant placement approach - with a healing time of six weeks before implant placement - was chosen. The bone augmentation with Geistlich Bio-Oss® Collagen was conducted simultaneously with implant placement. As this patient was treated in 1991, the case is one of the very first clinical applications of Geistlich Bio-Oss® Collagen.

Conclusion: A premolar grafted with Geistlich Bio-Oss® Collagen during implant placement showed good long-term result after 25 years. Satisfactory hard and soft tissue contour are present 25 years after implantation.
