The term “soft tissue paradigm” has been coined decades ago, emphasizing the patient-oriented treatment planning. However, the concept has hardly been translated into clinic possibly due to the limited understanding on the behavior of the facial soft tissue. According to our latest clinical experiences and researches, the miniscrew-type TADs and related appliances such as miniscrew-assisted RPE (MARPE) and torqued wires, have enabled not only individual tooth movement, but also predictable ‘total arch movement’ in three dimension. Combining the known rules-the hard tissue biomechanics and the soft tissue behavior- the next generation orthodontics are now realistic which will benefit both the orthodontists and patients. This course consists of main parts including esthetic orthodontics and therapeutic orthodontics. The first part deals with current concepts on non-surgical treatment on how to change not only the ‘occlusion’ but also the ‘face’ based on the ‘soft tissue paradigm’ from the esthetic standpoint. Applying those rules, answers to common clinical questions such as how to change the face in Class II, III and asymmetry without surgery, how to improve lip protrusion without extraction, will be given. For optimal treatment outcome, in addition to the three-dimensional movement, the fourth dimension (time and growth) will be utilized. The second part will discuss how to restructure the compromised occlusion in terms of transverse control, aiming to the non-extraction treatment. In each part, underlying biomechanical clues for total arch movement and the stability of the treatment will be intensively explained. Specified anatomical and biomechanical considerations can also help the operators achieve successful treatment outcomes with minimal laboratory work. Overall this course conveys practical concepts and techniques that can be taken home and translated into individual practice.


To provide the insights into the clinical meaning of soft tissue paradigm

To provide the insights into the biomechanics of the total arch movement

To provide the insights into the rationale and clinical outcomes of the maxillary expansion in adults


To explain the determinants of the soft tissue changes in the lower face

To explain the possibility of the total arch movement

To explain the possibility of the orthopedic expansion and transverse correction in adults

Learning outcomes:

The participants are able to conduct the clinical maneuver for critical decision making

The participants understand the miniscrew positions for specific total arch intrusion

The participants understand the design of the MARPE and how to activate for maximum success
