Combined orthodontic-surgical management of a transmigrated mandibular canine

Abstract

The presence of an impacted mandibular canine is one of the most difficult challenges that an orthodontist will meet. Orthodontic treatment is planned on an individual basis after thoroughly considering the patient's overall facial and dentoskeletal characteristics; the duration, risks, and costs of treatment; patient preferences; and the orthodontist's experience. This article reports an orthodontic treatment of a boy, age 12.9 years, with an impacted mandibular canine in the permanent dentition that was successfully managed. Radiographic analysis indicated a transmigration of the mandibular right canine. The orthodontic treatment plan included extraction of the deciduous right canine followed by surgical exposure and ligation of the permanent canine. Eruption was properly guided, and the correct position of the tooth was achieved. This challenging treatment approach is described in detail, including the mechanics used to align the impacted canine. (Angle Orthod. 2016;86:681-691.)

Orthodontic management of a dental anomaly pattern (DAP) including mandibular canine transmigration: A case report: A challenging treatment but worth it!

“…The ''surgical repositioning'' was done along with apicoectomy and immediate endodontics; 1-year follow up showed radiolucency at the apex. 21 Finally, in 2016, Cavuoti et al 22 published a case that depicted the treatment of a lower right transmigrated canine that was exposed and brought back across the midline, into its appropriate position through guided eruption. The case was similar to the one presented by Wertz 29 but exhibited greater control and concluded with excellent alignment.…”

Functional and molecular outcomes of the human masticatory muscles

“…The human masticatory muscles that specialize largely in jaw movement (Cavuoti et al., ; Matarese et al., ), that is, the masseter, pterygoideus lateralis, and medialis, temporalis, mylohyoideus, and digastricus, derive from the first branchial arch, presenting a common embryological origin (Schiaffino & Reggiani, ). However, their fiber arrangements and physiology are related to diet, craniofacial characteristics and eating and food habits, and are greatly variable between different species (Toniolo et al., ).…”

A Novel Temporary Anchorage Device Aided Sectional Mechanics for Simultaneous Orthodontic Retraction and Intrusion

“…In our case, prior use of high forces to retract the upper canines bilaterally on a 0.016 ″ NiTi wire resulted in such "roller coaster" effects. In the recent decade, many studies have shown a surge in the usage of TADs as direct anchorage for correction of transmigrated lower canines [11], upper [12], and molar uprighting [13] with the aid of sectional mechanics to nullify the unwanted side effects which accompany the use of archwire-guided mechanics or the usage of opposing dental components as anchorage.…”
