Lingual eruption of the permanent maxillary central incisors in the early mixed dentition can result in a traumatic anterior crossbite, causing mobility and gingival recession to the opposing mandibular incisors.
This case report presents a common finding of a 7-year-old boy with a dental crossbite and pseudo-Class III malocclusion caused by lingual eruption of the maxillary central incisors. An interceptive phase of orthodontic treatment was provided by bonding a beveled resin turbo on the mandibular incisors. The crossbite was corrected in 3 months without any orthodontic appliances. In the absence of the traumatic occlusion, the mandibular incisors stabilized and the gingival tissue was expected to regenerate.
Dentists and orthodontists can place beveled resin turbos on the mandibular incisors to jump an anterior dental crossbite conservatively, without the use of orthodontic brackets and wires.
在混合牙列早期,上颌恒中切牙舌侧萌出可导致创伤性前牙反合,致使下颌对刃切牙出现松动和牙龈退缩。
本病例报告呈现了一名7岁男孩的常见情况,其因上颌中切牙舌侧萌出导致牙性反合及假性III类错合。通过在下颌切牙上粘结一个斜面树脂突来进行正畸治疗的阻断性阶段。3个月内未使用任何正畸矫治器便纠正了反合。由于消除了创伤性咬合,下颌切牙得以稳定,且预计牙龈组织会再生。
牙医和正畸医生可在下颌切牙上放置斜面树脂突,以保守地矫治前牙反合,而无需使用正畸托槽和弓丝。
