Abstract: A new implant is designed innovatively for the purpose of protracting the maxilla in a growing class III patient. This implant is placed on the maxilla to give a protracting force from the reverse pull head gear without using the occlusal splint. FEM model along the implant is created to analyse the stress and displacement of the maxilla and its structures.
