About us
Preortho International Conference
We want to guide children’s oral functions toward proper development, helping them achieve proper dental alignment and occlusion so they can enjoy a healthy life throughout their lifetime. Many dentists share this vision.
To provide more reliable and effective treatment, we aim to share the challenges faced in daily practice and enhance our knowledge together.
