Morphological Characteristics of the Cranial Base of Early Angle's Class II Division 1 Malocclusion in Permanent Teeth

Morphological Characteristics of Soft Tissue Profile of Angle’s Class II Division I Malocclusion before and after Orthodontic Treatment

“…Chinese scholars found that the relationship between extraction treatment and change of nasolabial angle is different in adolescents and adults. Nasolabial angle of adolescents has no significant change when adult's increases obviously (Song & Wu, 2007;Wu et al, 2017), but there may be interference of growth and development. Therefore, although the study found that there was a correlation between the change of nasolabial angle and posterior occlusal plane with class II malocclusion patients, but in the other classifications, whether there is a relationship between them also requires further research.…”

A cephalometric evaluation of sexual dimorphism of the angle sella-nasion-frankfort horizontal plane in different sagittal classes of malocclusion in south Indian population

“…Few studies included a particular class of malocclusion without reference to sexual dimorphism such as a study by Bacon et al [10] on subjects with dental and skeletal Class II malocclusion; Tsang et al [11] indicated a steeper inclination of the anterior cranial base of on subjects with anterior open bite. The study of Alves et al [12] compared the inclination between the two cranial references lines in Class III and Class II group skeletal patterns while Shimizu et al [13] conducted a study on Class I subjects and Wu et al [14] appraised of the angle SN-FH in different vertical growth patterns of Class II Division 1 patients. Other studies such as Huh et al ,[6] Hung,[15] and Kattan et al [16] appraised the angle by gender stratification without any particular reference to vertical or sagittal malocclusion characteristic of malocclusion while the study by Shimizu et al [13] compared the Spanish and Japanese female subjects for the angle SN-FH in Class I Subjects.…”

Further, all the studies are on non-Indian population such as Brazilian study by Alves et al ,[112] Tsang et al ,[11] and Wu et al [14] on Chinese Subjects, Huh et al 's research[6] on Korean population, Spanish and Japanese subjects by Shimizu et al ,[13] Kattan et al [16] evaluation of Egyptian patients and a study on Nepalese population by Giri et al [17]…”

Micro-Implanted-Anchorage Safety: Cortical Bone Thickness in the Maxillary Posterior Region of Skeletal Class II Malocclusion

“…In recent years, with the continuous development of Micro-Implanted-Anchorage (MIA) materials and technology, MIA in the use of orthodontic increasingly common (Topouzelis & Tsaousoglou, 2012;Sivakumar & Sivakumar, 2014;Khan et al, 2016). Skeletal class II malocclusion patients after removal of premolars, through the MIA retracting anterior teeth to achieve the effect of treatment (Gandhi et al, 2017;Wu et al, 2017). The initial stability of the microscrew implantis closely related to the thickness of the surrounding cortical bone.…”
