Comparison of Self-ligating and Conventional MBT Brackets Regarding Alignment Efficiency and Pain Perception

The rate of Orthodontic tooth movement affects the efficacy and time duration of the treatment. One of the key factors, during the initial alignment phase, is the amount of the force that the arch-wire applies to the dentition. The amount of the applied force and the rate of tooth movement are directly proportional to the frictional resistance between the arch wire and bracket. The quality and degree of resistance is related to the physical characteristics of the arch wire, bracket material, arch wire dimensions, and the type of arch wire ligation. The estimated rate of tooth movement is about 0.35 to 2.04 mm per month, which is influenced by various factors and variables including the biological response of the individual to orthodontic forces, the complexity of the case, treatment mechanics and patient compliance throughout the course of treatment .
