Class II Correction with Microimplant Supported Molar Distalization: A Report of Two Cases

Figure 3

(a) When the open coil is extended, simultaneous distalization of the first and second molar will result and since it is a rigid system with indirect mechanics represented by the steel ligature, the whole system will rotate around a fixed point represented by the microimplant introducing maxillary incisor intrusion and counterclockwise rotation of the maxillary arch (green arrows). (b) Spontaneous distal drifting of premolars will follow.
