Classification Case report
 While approaching the patient with missing bilateral lower first molars, we should consider the treatment option whether to close the space or keep the space for prosthesis. If the patient wanted to replace the space with their own natural teeth instead of prosthesis, we should consider the treatment protocol and patient’s condition including resorption ridge and the degree of mesial-tilting adjacent molar. In this case report, we used mini-screw combined with periodontally accelerated osteogenic orthodontics (PAOO) and bone graft to treat patient suffering from missing bilateral first molars. Orthodontists need to consider the force mechanism: how to design the anchorage and move the teeth with translation motion. Concurrently, take the advantage of the regional acceleratory phenomenon (RAP) after PAOO with bone graft to enhance the rate of tooth movement and ridge augmentation at the same time . In the tentative results, this treatment protocol achieve the goal: move the second molars into the resorption ridge and replace the missing first molars.
