Summary
# Editorial Summary: Cephalometric Study of Overjet Development in Warmblood Foals Class II malocclusion represents the most common congenital dental problem in horses, yet little is known about which cases will resolve naturally during growth. Researchers from this 2019 study adapted cephalometric radiographic techniques from human orthodontics to track overjet development in 650 Warmblood foals, taking standardised lateral skull radiographs at five intervals up to 12 months of age and measuring 13 anatomical points and nine linear distances on each image. Of 13 foals presenting with measurable overjet initially, nine showed spontaneous resolution between 9 and 16 weeks of age, whilst four foals developed the condition de novo during the first year—demonstrating that overjet status is not static in young animals and that growth trajectories vary considerably between individuals. Cephalometric analysis proved sufficiently sensitive to differentiate foals likely to self-correct from those with persistent malocclusion, potentially allowing practitioners to distinguish cases requiring intervention from those amenable to conservative management. For equine professionals managing young Warmbloods with dental concerns, these findings suggest that early radiographic assessment using standardised cephalometric protocols could inform clinical decision-making and client counselling regarding prognosis and the timing of any corrective measures.

Practical Takeaways
- •Most overjet cases in Warmblood foals self-correct by 12 months; early intervention may not be necessary in the majority of cases
- •Serial radiographic assessment using cephalometric techniques can identify which foals will spontaneously resolve their malocclusion, potentially avoiding unnecessary treatment
- •Monitor foals without visible overjet at birth, as some may develop it during the first year of life
Key Findings
- •Class II malocclusion is the most frequently occurring congenital malocclusion in Warmblood foals
- •Of 13 foals with measurable overjet at baseline, 9 (69%) resolved spontaneously by 12 months of age
- •Four foals without overjet at 2 weeks developed the condition during the first year of life
- •Cephalometric measurements identified foals with spontaneous regression of malocclusion between 9-16 weeks of age
