Summary
# Editorial Summary Understanding how equine cheek teeth wear under normal chewing conditions has long challenged clinicians seeking to prevent dental pathology, yet until now, no computational model existed to simulate this process. Sterkenburgh and colleagues developed a two-dimensional finite element simulation incorporating published data on dental material properties and mandibular movement during the masticatory cycle, then tested how variations in lateral jaw excursion and incisor contact patterns influenced occlusal wear development. The model successfully replicated physiological wear patterns observed in living horses, including the natural inclination of the occlusal surface, and critically demonstrated how subtle alterations in chewing mechanics—particularly changes in lateral movement and incisor engagement—produced marked differences in wear distribution and abnormalities such as sharp enamel points. These findings suggest that minor biomechanical variations during mastication may be the primary driver of pathological wear development rather than static anatomical factors alone, fundamentally shifting how we might approach prevention and early intervention. For equine professionals, this work provides a mechanistic foundation for understanding why individual horses develop different wear patterns despite apparently similar diets and dentition, with direct implications for assessing chewing efficiency, predicting dental disease risk, and potentially informing management strategies to promote healthier occlusal development.

Practical Takeaways
- •Understanding that subtle differences in how individual horses chew can explain why some develop sharp enamel points and wear abnormalities—this may help identify horses at risk
- •The model suggests that addressing jaw movement patterns and incisor contact during dental examination and treatment could be key to preventing dental disease
- •This computational approach offers a foundation for predicting which horses might develop dental problems based on their individual mastication patterns, potentially enabling preventive intervention
Key Findings
- •Two-dimensional computerized simulation successfully replicated physiological occlusal wear patterns observed in living equids
- •Small variations in mandibular lateral excursion during mastication produce marked changes in wear patterns and formation of abnormalities
- •Incisor contact during the chewing cycle significantly influences occlusal surface wear development
- •Simulation integrating mechanical properties of dental structures and mandibular movement provides mechanistic explanation for sharp enamel point formation
