Fixed maxillary molar distalization appliance is an effective and noncompliance way for space regain. But with the increased confidence on skeletal anchorage, maximum anchorage preparation was planned with miniscrew in recent years. In this article, we cited two clinical cases to introduce an intraoral noncompliance appliance for maxillary molar distalization. RAMDA (rapid molar distalizing appliance) assist with skeletal anchorage is our modified technique used in these cases. From superimposition, we found that average rate of distalization was 1-2 mm per month. However, distal tipping of molar and anterior anchorage loss were also noted when using miniscrew as indirect anchorage.
