What is a biomaterial?
Biomaterials are non-viable materials that can be implanted to replace or repair missing tissue. They may be of natural origin or synthesised in a laboratory and are able to interact with the human body.
When is a bone augmentation needed?
- Dental implants: To support and augment the jaw bone when using dental implants, if the existing amount of bone is not sufficient for long-term stable tooth anchoring.
- Periodontitis: To preserve existing teeth that have lost their secure anchorage in the jaw bone as a result of periodontal disease (e.g. due to bacterial tooth plaque).
- Extensive bone damage: Bone reconstruction after extensive bone loss.
What are the manufacturing criteria for Geistlich biomaterials?
Meticulous selection of raw materials, together with a strictly controlled manufacturing process, allows Geistlich Bio-Oss®
and Geistlich Bio-Gide®
to conform to the highest safety requirements and ensures
Our strict manufacturing criteria:
- Careful selection of raw materials for the manufacture of Geistlich Bio-Oss® and Geistlich Bio-Gide®, using bone substance or collagen only from monitored establishments.
- Highly effective cleaning process using chemical and physical treatments and long periods of heating (Geistlich Bio-Oss®).
- Monitored production process with regular checks by independent institutions and state authorities.
- Sterilisation of end products.
- Documented quality assurance system.
What happens after a tooth removal?
The bone recedes in the weeks and months after tooth removal. This might cause some of the following problems:
- Aesthetic impairment: The gum follows the receding bone leading to visible blemishes.
- Hygiene problems: If you wear a bridge, the resulting gaps can make it more difficult, or impossible to clean.
- Difficulty with articulation: The change in the mouth affects articulation.
- Expensive and complicated follow-up treatments: The loss of bone has to be compensated later with laborious bone and soft-tissue augmentation.
What evidence is there that the biomaterials from Geistlich really work?
Geistlich Bio-Oss® and Geistlich Bio-Gide® have been part of the standard therapy in the field of bone reconstruction by dentists and dental surgeons for many years. They are the biomaterials most frequently used in regenerative dental medicine throughout the world. Geistlich Bio-Oss® and Geistlich Bio-Gide® have been used many million times, so extensive amounts of data and reports of experience exist. In addition, a great number of clinical studies document the reliability of both products.
What happens to the biomaterials after the implantation?
Geistlich Bio-Oss® is intermingled with new bone after four to six months and is then included in the natural remodelling process of the bone. The protective Geistlich Bio-Gide® membrane is broken down naturally by the body after a few weeks.
What are the causes of bone loss?
Bone loss can have many different causes – e. g. accidents, or inflammation of the gums and bone due to bacterial tooth plaque (periodontitis). Also after teeth have been removed the height and thickness of the jaw bone diminishes due to the lack of mechanical loading.
