Bone replacement materials

Today, bone replacement materials are used in dentistry, orthopedics and traumatology to treat bone defects caused by accidents or diseases.
There are many bone substitutes available for repairing bone defects and restoring bone structure. However, only the properties and synthetic nature of calcium phosphates (hydroxyapatite, tricalcium phosphate etc.) offer a safe and effective solution when bone grafts are needed, while preserving the patient's own bone stock.

Today, bone replacement materials are used in dentistry, orthopedics and traumatology to treat bone defects caused by accidents or diseases.

When used in the form of ceramic or calcium phosphate cement they promote bone reconstruction, as their properties and behaviour are similar to those of biological apatites which are constituents of the mineral phase of human bone. As they are synthetic, they reduce the risks related to infection and immune response that may arise with other types of bone substitutes.

Bone replacement after tooth extraction

Bone defects also develop as a result of complete tooth extraction. This can involve both vertical and horizontal bone loss.
The granulate is introduced into the cavity that is formed and is resorbed within 6 - 12 months. At the same time, missing bone is replaced by the patient's own, newly formed bone.
This treatment is particularly suitable for multiple extractions and front tooth extractions. The full regeneration and healing of the bone defect is important with regard to any implants that may subsequently be necessary.
Displacement of the teeth in the jaw, as a possible adverse consequence of the extraction, is prevented.

Bone replacement after apicectomy

If apicectomy is needed as part of a dental treatment, CerasorbR can be used to reconstruct the bone that is removed.
In apicectomy, bone is shaved off and the tip of the tooth's root removed. The resultant bone defect is treated by filling the cavity with bone replacement material, that is fully resorbed within 6-12 months and replaced by the patient's own, newly formed bone.
With larger defects, this filling is recommended. This considerably improves the conditions for any subsequent implantation which may become necessary. Aesthetic drawbacks caused by sinking of the mucosa are also avoided.

Periodontitis and bone replacement

Periodontitis is a disorder of the gums. Deposits form on the surfaces of the teeth, bacteria are concentrated in these deposits, grow and spread. Starting from the edges of the gums, the inflammation spreads between the teeth and to the surface of the teeth (called plaque), causing inflammation of the gums (gingivitis). When deeper areas of the gum are affected, this periodontal disease is called periodontitis.
Progression of periodontitis is associated with breakdown of bone in the jaw and loosening of the teeth, since release of pathogenic substances from the plaques results in destruction of bone in the jaw. Periodontitis patients suffer from pain, bleeding gums, discharges of pus from infected pockets, bad breath and loosening of the teeth. In highly complicated or special forms and in advanced disease, periodontitis leads to loss of teeth if not treated by a dentist.
If bone defects have developed due to periodontitis, bone replacement provides the option of reconstructing bone in the jaw following standard periodontitis treatment.
The jaw bone defects are filled up with bone replacement material acts as a guiderail and building material for subsequent bone growth. Bone replacement materials are resorbed after six to twelve months and replaced by new jaw bone.
