Chance paved the way for an invention that is used all over the world today. If Per-Ingvar Brånemark had not discovered a growth attachment instrument and taken the decision to carry out further research, we may not have had any titanium screws within medicine today.
In an experiment during the 1950s, Per-Ingvar Brånemark discovered that an instrument made out of titanium had grown on to the skeleton of a rabbit. Normally, the body resists and rejects foreign matter. Per-Ingvar Brånemark did further research and succeeded in creating the method which is applied today for the attachment of a number of different artificial limbs.
Fixing of teeth
The method, known as osseointegration, was used for the first time in 1965 to provide a toothless patient with new teeth. The technique is built on anchoring titanium directly to the jawbone without the need for any adjacent tissue. Over a period of time, the titanium grows together with the skeleton. The body does not resist or reject the titanium, but instead believes that it is a part of the body. The titanium screw functions as a tooth root, on which the dentist can attach a new artificial crown or dental bridge. Today, the method is very developed and is also used to attach artificial legs and prostheses for the face.
