The increasing demand for shorter orthodontic treatment durations has led to significant interest in accelerated orthodontic techniques. Conventional orthodontic treatment often requires 18–36 months to achieve satisfactory outcomes, which may increase the risk of dental caries, periodontal complications, root resorption, and patient non-compliance. Accelerated orthodontics encompasses a variety of surgical, physical, pharmacological, and biological interventions designed to enhance the rate of orthodontic tooth movement while maintaining treatment safety and effectiveness. This review evaluates the current evidence regarding accelerated orthodontic approaches, including corticotomy-assisted orthodontics, piezocision, micro-osteoperforations, low-level laser therapy, vibration devices, photobiomodulation, and pharmacological agents. Clinical outcomes, mechanisms of action, advantages, limitations, and future directions are discussed. Current evidence suggests that surgically assisted techniques and photobiomodulation demonstrate the most consistent acceleration effects, although further long-term randomized controlled trials are required. Accelerated orthodontics represents a promising field that may significantly improve patient experience and treatment efficiency in modern orthodontic practice.
