A prospective randomized clinical study comparing the alignment efficiency of four different ligation methods

To conduct a prospective randomized study comparing the efficiency of four different ligation systems (ELL,SSL,LL,PSL) over duration mandibular crowding alleviation. The was conducted in Department Orthodontics and Dentofacial Orthopaedics, Noorul Islam College Dental Sciences, Neyyattinkara, Trivandrum. present evaluated variations alignment alleviation patients during Eighty fulfilling inclusion criteria were selected equally divided into groups- Elastomeric (ELL), Stainless steel Ligation (SSL)- active passive , Leone slide Ligatures (LL). : mean treatment time for self ligating group (102 days) followed by leone (128 days), stainless (176 elastomeric (224 group. Thus showed no significant difference clinical performance between coventional, ligating, while PSL performed significantly superior to other groups. From above equation, initial phase orthodontic treatment.self-ligating brackets more efficient than conventional anterior alignment, space closure, incisal inclination.
