The 8
th
Korea-Japan Joint Symposium - Long Term Stability
Long-term stability after orthodontic treatment can be achieved with proper diagnosis, treatment and control of non-orthodontic forces
Dr. Haruya Ogawa
The purpose of orthodontic treatment is to obtain good aesthetic and functional treatment results and their long-term stability. To achieve "long-term stability" after orthodontic treatment, it is important to respect the orthodontic rules for long-term stability of treatment results, including to establish a stable and esthetic functional occlusion without occlusal interference. It is also important to control non-orthodontic forces, such as occlusion and habits. It is especially important to control the non- orthodontic force in cases that is difficult to achieve the long-term stability due to the skeletal characteristics.
Patient education is particularly important to improve their understanding and compliance. To achieve these objective, we also need the help of our office staff. Therefore, orthodontic treatment cannot be explained simply by science, and the sensitivity and experience of orthodontists have been emphasized.
In recent years, various devices have been devised and evolved as a method to move teeth, making it easier for even beginners to orthodontic treatment. However, no matter how simple and easy to handle, it is important to move the tooth to the position where it should be stable after treatment, because the target of the treatment is the living body.
In 2013, "Alexander Discipline Study Club of Japan" conducted a study on long-term stability using more than 200 cases with good profile and occlusion maintained for more than 10 years after treatment. That details were reported at the 73rd Japan Orthodontic Society（JOS） in 2014. I will talk about what is important for long-term stability and talk about the limitations for long-term stability due to the characteristics of the patient's skeletal pattern.
