“…Patients with Class II malocclusion usually have a convex facial profile and a retraction of the soft tissue pogonion. A very significant decrease in the convexity of the facial profile emerged in the group of subjects treated with TB, evaluated thanks to the increase in the angle of the convexity (CON angle) and very similar results were found by Baysal and Uysal and other authors [ 6 , 32 , 33 ]. A significant increase in the angle Z was also observed in the three groups of subjects treated, especially in the TB group, a direct consequence of the anterior displacement of the soft tissue pogonion.…”

To compare the skeletal, dental, and esthetic changes produced by three functional devices, Fränkel-2 appliance (FR-2), Twin Block (TB), and Occlus-o-Guide® (O-o-G®), for the treatment of Class II malocclusion. Methods: Sixty-five patients with Class II Division 1 malocclusion were divided into three groups and were analyzed through cephalometric analysis of skeletal, dental, and esthetic variables before and after treatment. The first group of 23 patients (F: 9; M: 14; mean age: 10.3 ± 1.08 years) was treated with FR-2, the second group of 18 patients (F: 8; M: 10; mean age 10.7 ± 1.05 years) was treated with TB, the third group (F: 11; M: 13; mean age: 9.05 ± 0.39 years) of 24 patients was treated with O-o-G®. The structural effects of the three devices were compared with a control group generated by the growth variations reported in the cephalometric atlas of Bhatia and Leighton. Esthetic analysis was performed comparing the results of the patients treated with a control group of 20 subjects with mandibular retrognathia and Class II Division 1 malocclusion, not subjected to therapy. Results: The three devices resulted in a significant increase in mandibular length, with higher results obtained for FR-2 and TB. A statistically significant increase in the IMPA angle was found for the O-o-G® group, and a notable reduction of both overjet and overbite was detected in all three groups of treated patients. The esthetic evaluation showed overall more significant results in the TB group, especially with regard to the reduction of facial convexity. The retrusion of the upper lip was on average more significant in the O-o-G® group, followed by that in the TB. Conclusion: All three devices have proven to be effective overall in resolving skeletal changes and improving facial esthetics.

“…17 Similar results were reported by Chaudhary et al whereby the soft tissue profile angle increased significantly after treatment. 22 One of the benefits of this research is to guide the thinking and practice of orthodontists and to aid in explaining the outcome of the treatment to the patient. Besides, the results from this research may also contribute information on the changes of soft tissue facial profile using Twin Block appliance and as a base data for future research in orthodontics.…”

Changes in soft tissue facial profile of class II skeletal malocclusion patients with retrognathic mandible treated with twin block appliance

Introduction: The soft tissue aspect in orthodontics treatment has gained attention in the last few years. The soft tissue profile is said to reflect the underlying skeletal profile, which causes a convex profile in patients with class II skeletal malocclusion. This research was aimed to determine the changes in the soft tissue facial profile of class II skeletal malocclusion patients with retrognathic mandible after twin block treatment. Methods: The type of research used in this study was retrospective descriptive research with paired t-test. The population was children aged 10-13 years old with class II skeletal malocclusion that were treated with twin block appliance in the Faculty of Dentistry Universitas Padjadjaran, Indonesia. The results of soft tissue changes before and after twin block treatment were compared. Results: There was an insignificant increase in soft tissue profile angle and Holdaway’s soft tissue angle after twin block treatment (p > 0.05). Whereas, Holdaway’s H-angle was decreasing and Merrifield’s Z-angle was increasing after twin block treatment, with statistically significant difference (p < 0.05). Conclusion: There was a decrease of H-angle, indicates a reduction in facial convexity and improvement of the facial profile after twin block treatment, but no difference in soft tissue profile angle and Holdaway’s soft tissue angle after twin block treatment. Keywords: Facial soft tissue profile, class II skeletal malocclusion, retrognathic mandible, twin block appliance

ürk toplumundaki görülme oranının %24 olduğu belirtilen Sınıf II maloklüzyonların mandibular yetersizlik, maksiller fazlalık ve glenoid fossanın posteriorda konumlanması sonucu oluşabildiği belirtilmektedir. 1,2 Tedavi planlamasının ise hasta yaşı, kalan büyüme miktarı, maloklüzyonun şiddeti ve yumuşak doku profiline bağlı olarak değişebil-diği ifade edilmektedir. [3][4][5] Büyüme ve gelişim dönemine göre Sınıf II maloklüzyona sahip çocuk ve gençlerde büyüme modifikasyonu uygulanırken; genç erişkinlerde dentoalveoler hareketlerden oluşan kamuflaj tedavisi; eriş-kinlerde ise ortognatik cerrahi uygulanmaktadır. 3 Literatürde önceki yıllarda yapılan araştırmalarda, Sınıf II maloklüz-yonların maksiller fazlalıktan kaynaklandığı belirtilmekteydi. 6 A An na ah ht ta ar r K Ke el li im me el le er r: : Sınıf II maloklüzyonlar; büyüme modifikasyonu; fonksiyonel apareyler A AB BS ST TR RA AC CT T Treatment planning of Class II malocclusions that are frequently encountered in orthodontic practice, can vary depending on severity of malocclusion, soft tissue profile, and amount of residual growth. In growing and developing subjects functional appliances are used to obtain the desired treatment results in skeletal, dental, and sof tissues by growth modification. It has been stated that the treatment effects of functional appliances that are differently designed and named may vary. The aim of this review was to investigate the studies of functional appliances on skeletal, dental, soft tissue, temporamandibular joint and airway effects with treatment time, made between 2012 and 2017.K Ke ey yw wo or rd ds s: : Class II malocclusions; growth modification; functional appliances A Ar rt ti ic cl le e i in n P Pr re es ss s
