Patients with class II malocclusion generally seek orthodontic treatment for esthetic concern. Various myo-functionl appliances can be used for the treatment of skeletal as well as the dental malocclusion in a growing patient. Among various functional appliances, twin block appliance is most commonly used due to better patient compliances. It redirects the mandibular growth to correct the maxillomandibular relationship, enhancing facial esthet ics. This article presents a modified design of the twin block appliance which is less bulky, more esthetic, can be used concurrently with fixed orthodontic appliance, and is easily accepted by uncooperative patients.
An 11-year-old-boy, who presented himself with a skeletal class II malocclusion, was treated with simultaneous use of fixed twin block along with fixed orthodontic appliance to correct both the skeletal and dental malocclusion. The twin block design was modified to have a better compatibility with the fixed orthodontic appliance. Pattanaik S, Puvvula N, Mohammad N.

Ⅱ类错颌畸形患者通常因美观问题寻求正畸治疗。对于生长发育期的患者，各种肌功能矫治器可用于治疗骨骼和牙齿错颌畸形。在各种功能矫治器中，双阻板矫治器因患者依从性较好而最常被使用。它可引导下颌生长以纠正上下颌关系，改善面部美观。本文介绍了一种改良设计的双阻板矫治器，其体积更小、更美观，可与固定正畸矫治器同时使用，且易被不配合的患者接受。
一名11岁男孩，患有骨骼型Ⅱ类错颌畸形，采用固定双阻板矫治器与固定正畸矫治器联合使用的方法，以同时纠正骨骼和牙齿错颌畸形。对双阻板设计进行了改良，使其与固定正畸矫治器具有更好的兼容性。帕塔纳伊克S、普武拉N、穆罕默德N。使用固定双阻板矫治器加速治疗骨骼型Ⅱ类错颌畸形。《国际临床儿科牙科学杂志》2018年；11(2)：146 - 150。
