This case report describes the application of fixed functional appliance in the treatment of an adult female having Class II division 2 malocclusion with retroclination of upper incisors. Fixed functional appliance was used to correct the overjet after the uprighting of upper incisors. Fixed functional appliance was fitted on a rigid rectangular arch wire. Application of fixed functional appliance achieved a good Class I molar relationship along with Class I canine relationship with normal overjet and overbite. Fixed functional appliance is effective in the treatment of Class II malocclusions, even in adult patients, and can serve as an alternate choice of treatment instead of orthognathic surgery. This is a case; wherein, fixed functional appliance was successfully used to relieve deep bite and overjet that was ensued after leveling and aligning. We demonstrate that fixed functional appliance can act as a "noncompliant corrector" and use of Class II elastics can be avoided.
本病例报告描述了固定功能矫治器在治疗一名患有安氏II类2分类错牙合畸形且上前牙舌倾的成年女性中的应用。在直立上前牙后，使用固定功能矫治器纠正覆盖。固定功能矫治器安装在一根刚性矩形弓丝上。固定功能矫治器的应用实现了良好的I类磨牙关系以及I类尖牙关系，覆盖和覆牙合正常。固定功能矫治器在治疗II类错牙合畸形方面是有效的，即使在成年患者中也是如此，并且可以作为正颌手术之外的另一种治疗选择。这是一个病例，其中固定功能矫治器成功用于缓解整平排齐后出现的深覆牙合和覆盖。我们证明固定功能矫治器可以充当“无需患者配合的矫治器”，并且可以避免使用II类弹力牵引。
