Combination of Active and Passive Orthodontic Appliances for Treatment of Linguoverted Mandibular Canine Teeth in 2 Shiba Inu Dogs.

Linguoverted mandibular canine (LMC) teeth are a common form of malocclusion in dogs. If left untreated, contact between the mandibular canine tooth crown tips and the palatal mucosa can result in ulceration, inflammation, infection, and potentially the formation of an oronasal fistula. Various treatment modalities have been described, including both active and passive orthodontic techniques. This report describes the combined use of an active appliance (elastic power chain) and a passive appliance (inclined plane) for the correction of unilateral and bilateral LMC teeth in 2 Shiba Inu dogs. Treatment duration was approximately 60 days in both cases, and follow-up examinations confirmed stable, functional, and atraumatic occlusion. This combined approach may represent an effective and safe treatment option for achieving self-retaining occlusion in similar cases.
