영문 초록

Skeletal Class II patients have characteristics such as a large overjet and Class II molar and canine relationships. The treatment goal is usually to make an appropriate anterior tooth relationship through retraction of the maxillary anterior teeth. The more the skeletal Class II pattern is severe, the more advantageous it is to maintain the mandibular anterior teeth in their original position to achieve the treatment goal. If there is an extraction space in the mandibular arch, space closing of the extraction space can increase the difficulty of Class II treatment because it can be accompanied by retraction of the anterior teeth. Since the introduction of temporary anchorage devices (TADs), protraction of posterior teeth has become easier. But for successfully posterior teeth protraction, the anterior-posterior, vertical, and transverse biomechanical considerations must be well considered. This case is a skeletal Class II patient with severe unilateral mandibular condyle resorption and unilateral mandibular molar defect treated with orthodontic treatment without implant treatment using TADs.
