Geistlich Bio-Oss® is the leading bone substitute for regenerative dentistry worldwide1,2. The outstanding osteo-conductive properties of Geistlich Bio-Oss® lead to effective and predictable bone regeneration3-5. Geistlich Bio-Oss® particles are incorporated over time within living bone which provides long-term volume preservation6-9. The biofunctionality of Geistlich Bio-Oss® is characterized by its topographic structure, hydrophilic properties and the biologic interaction that supports reliable bone formation. Subsequent application of a Geistlich Bio-Gide® collagen membrane enables undisturbed regeneration in the augmented area10.


When do you use the large Geistlich Bio-Oss® particles (1-2 mm) and when the small (0.25-1 mm)?

Fundamentally, the use of small particles is recommended for small defects (up to 2 dental alveoli) and for augmenting autogenous grafts, and the large particles for large defects (> 2 dental alveoli, sinus lifts). However, preferences can vary from dentist to dentist.

Can Geistlich Bio-Oss® also be used without membrane?

A membrane should be used as a barrier against ingrowth of soft tissue1. Native collagen membranes such as Geistlich Bio-Gide® also support wound healing and increase therapeutic safety in the event of a postoperative wound dehiscence2,3. Physicians should read the package insert prior to use.

Can Geistlich Bio-Oss® be re-sterilized?

No, if Geistlich Bio-Oss® is autoclaved, moisture can collect in the particles due to the high porosity of the product, which can change the hydrophilic properties. Moreover, Geistlich Bio-Oss® is not approved for re-sterilization in dental practice. Geistlich does not recommend re-sterilization under any circumstances.

Should Geistlich Bio-Oss® be mixed with antibiotics?

The use of local antibiotics is generally unnecessary when utilizing Geistlich Bio-Oss®.

Is Geistlich Bio-Oss® safe (transmission of diseases such as BSE)?

Geistlich Bio-Oss® is made from the mineral part of bovine bone. The strictly controlled manufacturing process ensures high quality and safety standards by:
Country of origin: Australia (and for some countries also New Zealand)
Selected and certified slaughterhouses
Pre- and post-mortem health inspection for each individual animal
Extremity bone (according to WHO Guideline on tissue infectivity classified as tissues with no detected infectivity or infectious prions)
Effective inactivation methods with 15h treatment at high temperature and cleaning with strong alkaline solutins
Sterilization, double sterile packaging
Official controls by international authorities

Do I have to use venous blood or can I use blood from the defect?

Blood from the defect may be used for mixing. Care should be taken to avoid contamination with salivary bacteria.

Is it possible to get an allergic reaction to Geistlich Bio-Oss® Collagen and Geistlich Bio-Gide®?

Since Geistlich Bio-Oss® Collagen and Geistlich Bio-Gide® are made of collagen, allergic reactions and inflammatory tissue reactions cannot be ruled out. These are, however, extremely rare.
