The force required to produce a tipping movement in orthodontics is typically 50-75 grams. This range is sufficient to overcome the resistance of the periodontal ligament without causing damage to the supporting structures. Forces below this threshold may be ineffective, while higher forces can lead to root resorption or undesired movement. The application of controlled, optimal force ensures safe and predictable tooth movement by allowing remodeling of the alveolar bone while preserving periodontal health.
