Because of its anatomical/physiological characteristics, the Class II division 2 (class II, div. 2) is one of the malocclusions considered as a possible risk factor for Temporomandibular disorders (TMD). A literature review was conducted from the electronic databases of Medline and Elsevier Masson, through the year 2010, in order to clarify the relationships that may exist between Class II division 2 and TMD. This research helped identify 50 articles: 7 articles specifically concerned the Class II div. 2, 37 articles concerned some of the characteristics of the Class II div. 2, considered individually (Class II, deep bite, retroclined maxillary incisors, mandibular retrognathism) and 6 articles orthodontic treatment. From the conclusions of these studies, the Class II, div. 2 does not appear to represent a significant risk factor for TMD. The clearest association would involve mandibular retrognathism and the risk of articular disk displacement. However, given the low number of articles published on this topic, the methodological variability and the contradictory results, it is difficult to identify reliable conclusions and, consequently, the therapeutic indications for the treatment of Class II div. 2 patients with TMD.
由于其解剖学/生理学特征，安氏II类2分类错（牙合）畸形（安氏II类2分类）被认为是颞下颌关节紊乱病（TMD）的一个可能危险因素。为了阐明安氏II类2分类与TMD之间可能存在的关系，我们通过检索Medline和爱思唯尔马松电子数据库，对截至2010年的文献进行了综述。该研究共筛选出50篇文章：7篇专门针对安氏II类2分类，37篇分别涉及安氏II类2分类的某些特征（安氏II类、深覆（牙合）、上颌切牙舌倾、下颌后缩），6篇关于正畸治疗。从这些研究的结论来看，安氏II类2分类似乎并非TMD的显著危险因素。最明显的关联可能是下颌后缩与关节盘移位风险之间的关系。然而，鉴于关于该主题发表的文章数量较少、方法学的多样性以及相互矛盾的结果，很难得出可靠的结论，因此也难以确定治疗患有TMD的安氏II类2分类患者的治疗指征。
