“…7 Interestingly, both of the larger values are quite similar with the PAC values of Indian adults with class II subdivision malocclusion. 7 These differences may depend on subject selection criteria.

“…These results coincide with the previously published researches on Brazilian 43 and Indian 7 PAC. Jabeen et al 7 found asymmetries in relation to normal occlusion group as well as in the class II subdivision group of malocclusion subjects. Their results are quite similar in both groups.…”

“…6 Most studies of facial asymmetry have reported that the right hemiface is usually wider than the left; however, fewer studies have reported on the laterality of chin deviation, a subject that also remains controversial. 1,2,4,6,7 Hence, the purpose of this study was to investigate the asymmetry of the face using GA in Saudi adult male subjects and investigate the difference in asymmetry with published data.…”

Objectives:The prime aim of the following study is to measure the facial parameters of the horizontal plane, mandibular morphology and linear asymmetries using Grummons analysis (GA). Materials and methods:Standard posterior-anterior cephalogram (PAC) of 100 esthetically pleasing faces without any orthodontic treatment and craniofacial deformity were taken from the radiology archive. All radiographs are digitally analyzed for the GA. Various linear and angular variables were measured for horizontal plane, mandibular morphology, and linear asymmetries.Results: Descriptive analysis has been done using SPSS software. Mean disparities has been calculated to check the difference between different parameters with other ethnics. GA of PAC of Saudi adult male showed variable degrees of facial asymmetry. The lower third of the face showed greater asymmetries. Mandibular deviation, maxillary midline deviations, and mandibular midline deviation are 3.51 mm, 2.52 mm and 2.86 mm, respectively. Conclusion:This study has measured PAC; horizontal plane, mandibular morphology and linear asymmetries for the Saudi adult male using GA. Facial asymmetries are found to have a common finding in Saudi adult male subjects who have normal facial harmony.

: To evaluate and compare the asymmetries in subjects with two malocclusions that is Class II subdivision, Class II div 1 and normal occlusion.: 90 subjects ranging from 15 to 30 years divided into 3 groups A, B, C. Group A – Class II subdivision, Group B – Class II division I, Group C – Normal Class I occlusion. Angular, linear paired, linear unpaired measurements were calculated based on the Van De Coppell analysis using PA views.: Asymmetry was found in all the three groups where Group A patients showed greater degree of asymmetry near maxillary buttress and piriform aperture areas compared to the three groups. Group C patients showed greater degree of asymmetry in the occlusal plane angle. All the three malocclusions that is Class II div 1 Subdivision, Class II div 1 and Class I malocclusions showed equal amounts of asymmetry. Class II subdivision patients showed greater asymmetry near maxillary buttress area and piriform aperture. Class I malocclusion showed deviation in occlusal plane angle. Along with the lower third involving mandible, maxillary area also can equally show asymmetry in both skeletal and dental parameters.

The treatment of the Class II subdivision presents a real challenge in orthodontics, and a lot of discussions are created around it with one important question: What is the best treatment option? We report one young female Patient with Class II subdivision malocclusion treated with an asymmetric extraction of the first permanent maxillary molar on the side of the distoclusion. In this case, we take advantage of the space created from the extraction site to correct the distoclusion and substitute the first molar with the second molar, and by preserving the third molar, we substitute the second maxillary permanent molar with this tooth. The results reveal a good vertical control, Class I molar and Class I canine was achieved accompanied by a correct alignment and leveling of the maxillary and mandibular arches. With this approach, we can respect the geometry of the arch without esthetic damage, functional problems at the level of the temporomandibular joint, keeping all the correct occlusal relationships and guides of dynamics associated with correct arch shape and clear harmony in the excursive movements. It is clinically justifiable to strive for an orthodontic result that respects the spherical functionality proposed by Slavicek.
