Molar distalization with the acrylic cervical occipital appliance

Dentofacial effects after the use of bone anchorage pendulum appliance

“…In other words, the two appliances were equally likely to tip the maxillary molars. These distal tipping and movements of the maxillary first molars were also found in other BAPA (36,59,60) as Kircelli et al, (36) (6.4 mm, 10.9°), Ozsoy et al, (57) ( 4.8 mm, 9.1°), and Önçag˘ et al, (58) (5.1 mm, 7.06°). Molar distalization and tipping in the PA group was found in Bussick and McNamara (3) (5.7 mm, 10.6°), Byloff and Darendeliler (24) (3.39 mm, 14.5°),…”

“…Maxillary molar distalization continued till achieving super Class I molar relation. This overcorrection is necessary and routinely prepared anchorage for all distalization treatment, because molar anchorage loss will invariably occur during retraction of the premolars, canines, and incisors (60,61) .…”

Comparison Between Bone Supported -Pendulum Appliance and Lever-arm Mini-implant System in Maxillary Molar Distali zation in Class II Malocclusion

“…Over correction of upper molars is recommended to avoid anchorage loss that may occur during the retraction of incisors, canines and premolars. 26 The duration of distalization in the BAPA group There was a highly significant increase in the upper arch perimeter in both groups, 16.1 mm in BAPA group within 7.2 months and 12.9 mm in LAMS group within 10.56 months and the difference between the two groups was not significant in amount but significant in time.…”

Upper molar distalization: a critical analysis

“…If anchorage loss exceeds 2 mm, it is recommended to bracket the incisors, place a sectional wire so that Class II elastics (100 g) can be placed. The lower arch anchorage can be augmented by a lip bumper (12). The use of a bite plate to disclude the posterior teeth can allow a faster distalization, however, it could result in a clockwise mandibular rotation.…”
