To use published data to evaluate quantitatively the dental effects of noncompliance intramaxillary appliances in individuals with Class II malocclusion.
A literature search was carried out identifing 13 prospective or retrospective clinical studies matching inclusion criteria. Only appliances with conventional anchorage designs were considered for the review. The data provided in these publications were grouped and analyzed in terms of molar distalization, tipping and vertical movements, and incisor and premolar mesialization, tipping, and vertical movements.
Maxillary first molars showed distal crown movement and tipping greater than the mesial crown movement and tipping shown by incisors and premolars. Vertical movements of incisors and premolars were in general extrusive, but molars were intrusive or extrusive, depending on the study and the type of appliance used. Appliances that acted palatally seemed to display a smaller distal tipping movement, as well as smaller incisor and premolar mesial tipping movements, when compared with those that acted buccally. Friction-free appliances, namely the pendulum, produced a large amount of mesiodistal movement and tipping, if no therapeutic uprighting activation was applied.
Noncompliance intramaxillary molar distalization appliances all act by distalizing molars with a concomitant and unavoidable loss of anchorage, as revealed by incisor and premolar mesial movement. Buccal acting and palatal acting appliances demonstrate almost similar results, with palatal acting appliances showing less tipping. Friction-free palatal acting appliances appear to produce better molar distalizing effects, but with a concomitant notable loss of anchorage.
利用已发表的数据定量评估Ⅱ类错颌畸形患者使用上颌内非依从性矫治器的牙齿效应。
进行文献检索，确定13项符合纳入标准的前瞻性或回顾性临床研究。本综述仅考虑具有传统支抗设计的矫治器。对这些出版物中提供的数据按照磨牙远中移动、倾斜和垂直移动，以及切牙和前磨牙近中移动、倾斜和垂直移动进行分组和分析。
上颌第一磨牙远中牙冠移动和倾斜大于切牙和前磨牙的近中牙冠移动和倾斜。切牙和前磨牙的垂直移动一般为伸长，但磨牙的垂直移动为压低或伸长，这取决于研究和所使用的矫治器类型。与颊侧作用的矫治器相比，腭侧作用的矫治器似乎显示出较小的远中倾斜移动，以及较小的切牙和前磨牙近中倾斜移动。无摩擦矫治器，即摆式矫治器，如果不施加治疗性直立激活，会产生大量的近远中移动和倾斜。
上颌内非依从性磨牙远中移动矫治器均通过使磨牙远中移动起作用，同时不可避免地伴有支抗丧失，如切牙和前磨牙近中移动所示。颊侧作用和腭侧作用的矫治器显示出几乎相似的结果，腭侧作用的矫治器倾斜较小。无摩擦腭侧作用矫治器似乎能产生更好的磨牙远中移动效果，但同时伴有明显的支抗丧失。
