This thesis explores practical and evidence-based ways to safely shorten orthodontic treatment time. It explains how tooth movement works at the biological level, especially the role of bone remodeling and the regional acceleratory phenomenon (RAP). Both surgical techniques, such as corticotomy and piezocision, and non-surgical methods, including laser therapy, vibration, electromagnetic fields, and certain medications, are carefully reviewed and compared. The study evaluates their effectiveness, safety, and possible side effects like root resorption or periodontal changes. It also discusses minimally invasive and conservative approaches that aim to improve patient comfort and treatment efficiency. Overall, this work provides a clear and balanced overview of how orthodontic treatment can be accelerated without compromising long-term stability or oral health.
