What does this research mean for the field?

Occlusal loading significantly influences the biomechanical environment of the periodontal ligament during mandibular canine distalization, with a moderate force of 1.47 N producing the most favorable response under nonocclusal conditions. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Finite element analysis evaluates how occlusal conditions and orthodontic force levels affect canine movement, suggesting important biomechanical insights.

Key Points

This research investigates how different occlusal conditions and levels of orthodontic force impact mandibular canine distalization using finite element analysis.
Three-dimensional symmetric finite element analysis model was created based on bilinear periodontal ligament properties.
Five occlusal conditions—intercuspal position, incisal clench, right unilateral molar clench, right group function, and no occlusion—were tested at three force levels (0.98, 1.47, 1.96 N).
Hydrostatic stress and maximum principal strain were measured to assess biomechanical effects on the periodontal ligament.
1.47 N force under nonocclusal conditions showed a favorable biomechanical response with optimal stress and strain.
Intercuspal position and incisal clench led to higher stress and strain concentrations in the periodontal ligament.
Right unilateral molar clench maintained symmetry, while right group function caused uneven responses in the periodontal ligament.
