Resistance to Sliding in Orthodontics

Friction is a mechanical phenomena that resist every procedure used to move teeth. This phenomenon is a challenge for every orthodontist to overcome. These effects are most evident when using sliding mechanics a very popular method used in contemporary orthodontics to close or regain space in the dental arch. Understanding the various components of resistance that happens during sliding helps the orthodontist to improve treatment by providing more efficient and reproducible fixed orthodontic appliances. Various components of resistance to sliding factors that influence this resistance methods to overcome this resistance and clinical implications of these forces are discussed in detail.
