Rodent and Lagomorph Tooth Extractions, Loïc Legendre, DVM, JVD
Why should you push and rotate the tooth in the alveolus during the extraction process of an incisor tooth in a rabbit and rodent?
The pushing and rotating not only loosens the tooth in the alveolus but also damages the germinal tissue to minimize regrowth of the tooth
Rodent and Lagomorph Tooth Extractions, Loïc Legendre, DVM, JVD
What sides should you luxate on when extracting the second premolar tooth in a rabbit? What technique should you use?
buccal, palatal, mesial and distal (All sides!) Push the luxator apically and oscillate it in order to cut the periodontal ligament fibers
Rodent and Lagomorph Tooth Extractions, Loïc Legendre, DVM, JVD
What teeth are curved luxators used on? and right angled luxators?
Curved luxator = incisors Right angle luxators= cheek teeth

Rodent and Lagomorph Tooth Extractions, Loïc Legendre, DVM, JVD
When is arresting elongation of continuously growing mandibular cheek teeth indicated?
Cases of malocclusion where the mandibular teeth are solid, non-infected or ankylosed
Rodent and Lagomorph Tooth Extractions, Loïc Legendre, DVM, JVD
How do you arrest elongation of cheek teeth?
Amputation of the last 3-5 mm of apical crown and the germinal tissue Skin incision, masseter muscle is moved dorsally to expose the mandible Mandible is fenestrated to expose the apical part of tooth Tooth is sectioned and removed with germinal tissue The remaining crown is left to migrate coronally and finally fall out in the mouth
Rodent and Lagomorph Tooth Extractions, Loïc Legendre, DVM, JVD
What are the two ends of this instrument used for?
Incisor luxation for rabbits and rodents. The more curved end is better for the more pronounced curvature of the maxillary incisor teeth. The less curved end is better suiteed to the mandibular incisor teeth.
