Osteodistraction (bone and soft tissue stretching) is a method of extending or lengthening of bone, which is based on the self-healing powers of the human body. Two previously severed pieces of bone, are slowly pulled apart step by step, which is forming new bone tissue (so-called callus).
To pull apart the two bone parts, a small distraction device is installed, which can be activated by the patient himself daily. This stimulus activates bone healing, so that new bone tissue is continuously formed. The smaller the distractions steps are, the more intense the callus formation is.
An advantage of this method, apart from the formation of new bone it also results in corresponding stretching and reproduction of the surrounding tissue. The method is particularly suitable for larger, vertical bone defects, e.g. after traumatic loss of teeth in the maxillary anterior area.
The advantages of this method are as follows:
- In addition to bone also soft tissue will be stretched
- A bone graft with a complex transplant recovery is no longer necessary
- Low infection risk, because living bone is distracted
