 Mini implants have been used to eliminate headgear wear and to establish stationary anchorage. In this case report, distalization was achieved with a modified TPA with soldered J-hooks, which were coupled to palatal implant with e-chains. Two mini screws of dimension of 8 mm length and 1.8 mm diameter were placed interdentally between 2nd premolar and 1st molar. The results showed that the maxillary molars were distalized bodily without causing anchorage loss or distal tipping, extrusion or rotation of the molars. Final results showed improvement in lip profile, smile esthetics and achievement of class I molar and canine relationships. In conclusion, palatal interdental implants can be used effectively for maintenance of anchorage and in space-gaining procedures.

 Key words: Mini screws, Distalization, Maxillary molars.
