Comparison of Complications in Removable Mandibular Acrylic Splint and Cantilever Herbst for Management of Class II Malocclusion: A Retrospective Study

Abstract

Introduction: Numerous appliances are present for the management of class II malocclusion. We have conducted a study to compare the clinical complications during treatment with either a removable mandibular acrylic splint (RMS) or with a cantilever Herbst (HC) appliance for the management of class II malocclusion. Materials and methods:This study consisted of records of 114 patients (61 males, 53 females), who were divided into two groups. Group I received RMS and group II received HC for the treatment of class II, Division 1 malocclusion. They were further subdivided according to the telescopic system used [Dentaurum type I or propulsor mandibular abzil (PMA)] and fixation mode (splint with crowns or GripTite bands). Patients' clinical records were assessed to identify clinical complications. Results:The results of the study showed that the incidence of complications during treatment in both groups was statistically nonsignificant. The complications with either crown or band were also statistically nonsignificant. The Dentaurum group showed more susceptibility to complications than the PMA group. Conclusion:The PMA telescopic system is more efficient as compared with Dentaurum. Complication resulting from Herbst appliance is independent type of appliance used and mode of fixation.

Theefficiency of Orthodontic Treatment of Classii Malocclusion in Children With Β -Thalassemia Majo

“…A bigger mandibular growth is a desirable outcome in the treatment of distal occlusion. Kanuru at all., in his study, highlighted the effect of activators on mandibular growth [13].…”

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

“…In recent years, more and more scholars pay attention to the importance of occlusal plane, which is a main reference indication in diagnosis and treatment of malocclusion. The inclination of occlusal plane, especially posterior occlusal plane has important effects on establishment of the position and growth of mandibular (Hajeer, 2014;Kanuru et al, 2017). It should pay more attention to controlling occlusal plane in orthodontic treatment.…”

Herbst Apareyi̇ İle Yapilan Ortodonti̇k Tedavi̇de Karşilaşilan Kompli̇kasyonlar

“…CH tipi Herbst; üst ve alt molar dişlerde olmak üzere dört pas-lanmaz çelik kron, üst molar dişler arası transpalatal ark, alt birinci küçük azı dişlerde okluzal restli bir lingual ark ve alt premolar dişler arasında cantilever Herbst'ün mesial ucuna yerleştirilmiş kalın bir koldan oluşan Herbst tasarımıdır. 25,26 Bu farklı dizaynlar değerlendirildiğinde, CH grubunda %35,3 oranında vida gevşemesinin meydana geldiği ve %29,4 oranında piston deformasyonunun gerçekleştiği rapor edilmiştir. Hareketli akrilik splint Herbst grubunda ise %43,2 oranında vida gevşemesiyle karşılaşıldığı ve %34,4 oranında da akrilik kırılmasının görüldüğü bildirilmiştir.…”
