Background: The orthodontic biomechanics is based on the principle of elastic energy storage and its conversion into mechanical energy during the tooth movement. The bending testing, but only on aesthetic covered arch wires collected from patients with minor crowding, without any extractions of premolars treated with fixed devices. Hence; the present study was undertaken for evaluating the incidence and location of fracture in round orthodontic arch wires. Materials & methods: A total of 125 orthodontic patients (239 arch wires) were included in the present study. Evaluation of all the patients was done during the regular treatment visits. Assessment of fracture of arch wires and their location was done. Complete demographic and clinical details of all the patients were obtained. Details about type of arch wires, type of brackets and time period of treatment before fracture was recorded separately. All the results were recorded in Microsoft excel sheet and were analysed by SPSS software. Results: Overall incidence of arch wire failure was 4.8 percent. Majority of arch wire failure occurred in 0.014” archwire. Out of 6 cases of arch wire failure, 4 was present maxilla while the remaining 2 were present in mandible. While evaluating the incidence of arch wire failure in maxillary arch and mandibular arch, non-significant results were obtained. Conclusion: Incidence of arch wire fracture during regular orthodontic visits is significantly low. Key words: Fracture, Archwire, Location
