“…In before-used distalizing methods, anchorage preparations were extraoral anchorage; 2 occlusal wire rests; palatal acrylic button, for instance, pendulum appliance; skeletal anchorage, such as combination of palatal acrylic button with mini-screw; 30 and the zygoma anchorage system for buccal segment distalization. 34 , 35 , 36 …”

“…For bodily movement, the vector of distalizing force should pass through the center of resistance of the target segments, e.g., heavy rods (power arms) should be used to control the direction of force. 25 With the Frog appliance, 25 the Distal Jet, 16 , 17 , 18 the Keles slider, 19 Zygoma-Gear Appliance 36 and Miniscrew Implant Supported Distalization System (MISDS), 33 , 44 the force vector is approximately at the level of the center of resistance of the first molar. The higher vertical position of the hook on mesially extended transpalatal bar and MI-supported S-sheath makes the line of action of force higher than the center of resistance of the molar segment to set distalizing and intruding molars.…”

“…Routine anchorage units used in these appliances are other teeth or palatal acrylic pad. 26 Recently, bone-borne appliances, such as dental implants, 27 fixation mini-plates 28 and orthodontic mini-screws 29 - 33 have become widely used as anchorage system; for instance, Graz implant-supported pendulum appliance, 28 bone-anchored pendulum appliance, 29 - 32 a mini-screw implant-supported distalization system (MISDS), 33 the ZGA (Zygoma-Gear Appliance) anchorage system for buccal segment distalization, 34 , 35 , 36 dual-force distalizer supported by mini-implants (DFD), 37 mesialy extended TPA (ME-TPA) with skeletal anchorage, 38 the Keles Slider appliance with a palatal implant 39 and timely relocation of mini-implants for uninterrupted full-arch distalization (jig). 40 …”

Objective: The aim of this study was to introduce a new method for bilateral distal movement of the entire maxillary posterior segment.Case report: A 17-year-old girl with Class I skeletal malocclusion (end-to-end molar relationships, deviated midline and space deficiency for left maxillary canine) was referred for orthodontic treatment. She did not accept maxillary first premolars extraction. A modified Hyrax appliance (Dentaurum Ispringen, Germany) was used for bilateral distalization of maxillary posterior teeth simultaneously. Expansion vector was set anteroposteriorly. Posterior legs of Hyrax were welded to first maxillary molar bands. All posterior teeth on each side consolidated with a segment of 0.017 × 0.025-in stainless steel wire from the buccal side. Anterior legs of Hyrax were bent into eyelet form and attached to the anterior palate with two mini-screws (2 × 10 mm) (Jeil Medical Corporation Seoul, South Korea). Hyrax opening rate was 0.8 mm per month. Lateral cephalometric radiographs were used to evaluate the extent of distal movement. 3.5-mm distalization of posterior maxillary teeth was achieved in five months.Results: A nearly bodily distal movement without anchorage loss was obtained.Conclusion: The mini-screw-supported modified Hyrax appliance was found to be helpful for achieving en-masse distal movement of maxillary posterior teeth.

“…16,17 The use of miniscrew and miniplate anchorage in orthodontics has reduced the undesirable effects of many appliances. [18][19][20][21] Few studies 16,17,22,23 have shown the use of the Herbst and Forsus Fatigue Resistant Device (FRD) with miniscrew anchorage. Those studies 16,22,23 have shown that the skeletal response to the Herbst appliance was increased by minimizing the protrusion of the mandibular incisors, while the overjet and molar correction in patients treated with the Forsus FRD combined with miniscrew anchorage were totally dentoalveolar.…”
