Management of Mesioverted Maxillary Canine Teeth and Linguoverted Mandibular Canine Teeth

Abstract

Mesioverted maxillary canine teeth in combination with linguoverted mandibular canine teeth are a common ramification of persistent deciduous maxillary and mandibular canine teeth. Without the physical presence of the mandibular canine teeth, the maxillary third incisor and canine teeth diastemata are frequently narrowed. The creation of normal occlusion requires treatment of all 4 canine teeth; the mandibular canine teeth must be tipped labially and the maxillary canine teeth must be tipped and/or partially translated distally. This case report discusses the novel integration of 2 well-described orthodontic techniques to simultaneously treat both mesioverted maxillary canine teeth and linguoverted mandibular canine teeth, achieving a comfortable, functional occlusion.

Outcome of Surgical Extraction of Linguoverted Deciduous Mandibular Canine Teeth, Performed as an Interceptive Orthodontic Procedure in Puppies, on Permanent Occlusion

“…More recent studies, based on genome mapping techniques (genome-wide association studies-GWAS), identified loci on the canine genome associated with craniofacial and teeth development [14][15][16] at the same time proving the complexity of the genetics of skull development. 12 Currently, most authors agree that many malocclusions involving mandibular canine teeth in dogs are hereditary, [17][18][19][20] although admittedly genetic studies to prove the hereditary nature of these malocclusions are lacking. 19 Additionally, current concepts of human orthodontics, supported by studies of the human genome and family studies, [21][22][23] proved heritability of the development and eruption time of deciduous teeth and eruption time of permanent teeth, facial width, or teeth size that are involved in the development of malocclusions.…”

Success of orthodontic treatment of linguoverted mandibular canine teeth using a direct inclined plane appliance

“…To accomplish concurrent treatment, the IP must be applied to the maxillary canine tooth only. Concurrent treatment with an IP and an active orthodontic device was successful in treating these malocclusions simultaneously in one case report ( 14 ). In this study, 66.7% (2/3) of the teeth treated concurrently with an active force appliance were successful.…”

Orthodontic Inclined Plane Application Using a Visible Light Cure Acrylic Material for Treatment of Linguoverted Mandibular Canine Teeth

“…In patients where there is concurrent mesioversion of the maxillary canine teeth resulting in narrowing of the interdental spaces, combined orthodontic therapy of teeth 104 and 204 with elastic chain appliances and placement of single tooth inclined planes has been described. 6 Surgical extraction is invasive, leads to loss of mandibular alveolar bone and loss of tooth function, and increases the risk of iatrogenic mandibular fracture and postoperative tongue protrusion. 7,8 Crown amputation followed by vital pulp therapy is a popular alternative to exodontia.…”

“…This treatment option also requires regular oral exams and intraoral radiographs to evaluate tooth vitality. 2,9,6 Orthodontic treatment alters the position of the teeth to achieve a functional, stable, and harmonious occlusion. 3 The inclined plane technique for orthodontic movement of linguoverted mandibular canine teeth has been utilized by veterinary dentists for years with positive results.…”

“…3 The inclined plane technique for orthodontic movement of linguoverted mandibular canine teeth has been utilized by veterinary dentists for years with positive results. 3,1,2,6 Use of this appliance design for definitive orthodontic movement can preserve full function of affected teeth and mandibular integrity for the lifetime of the patient.…”
