The push molar distancing technique can be divided into patient-dependent and non-patient-dependent techniques. In the patient dependence technology, the external force of the extraoral arch device is used as an anchorage, lip inclination of front teeth is avoided to the greatest extent, but the patient can only wear the correction device when sleeping, the degree of matching of the patient directly influences the quality of correction results, the application is very inconvenient, and the correction effect has uncertainty.
To overcome this disadvantage, prior art appliances have emerged that are not patient-dependent and can achieve 24 hours of continuous application of the correction force, the common feature of which is that the anchorage is intra-mandibular.
