Biomechanics in orthodontics: A review


Khalid Ashraf, Rohit Kulshrestha, Shailesh Shenava, Prakash Mudaliar, Harmeet Kaur, Gaury Vajarekar

In the execution of an orthodontics treatment plan, levelling and alignment is the most important part. This is usually achieved by placing brackets on the malaligned teeth, which are of increasing thickness. Adequate and favourable tooth movement may or may not result by the force generated on insertion of straight wires into brackets of such teeth, which depends on geometric relationship and also the expected outcome. Whether an applied force system with the use of straight wire is beneficial is determined by analyzing the relationship between adjacent teeth. When the side effects of the insertion of straight wire are unwanted, alternate treatment plans like use of inter arch, extra oral, or auxillary appliances is indicated. With proper treatment planning and evaluation of the force systems generated, any unplanned tooth movement can be avoided and overall treatment efficiency can be improved.
