Introduction: The main components of modern fixed appliances are bands, tubes, brackets and arch wires. Metal bands are cemented to molars while tubes made of metal have a mesh at the base for bonding to molars. Objective: The objective of the study was to assess the highest failure rate of cemented molar bands vs bonded molar tubes, also to determine the tooth which has maximum times of failure with both molar bands and tubes or in individual. Materials and Method: A total of 178 patients meeting the inclusion criteria were selected for the study in which 712 bands and 712 tubes were assessed for breakage during the complete orthodontic treatment. Result: All the molars showed failure, the mean breakage of both bands and tubes of molars were different. The maximum times the bond failure was seen with 17. Fifty six bond failures were recorded with a mean of 0.62 failure rate, while the most frequently the failures of both banding and bonding was seen with the mean of 0.67±2.6 in 36.The mean breakage of 16 with both bands and tubes was 0.54±1.2, 17 was 0.61±1.3, 26 was 0.62±1.9, 27 was 0.66±2.0, 36 was 0.67±2.6, 37 was 0.57±2.7 respectively. Ultimately tubes breakages were comparatively more than bands failure. Conclusion: Though cementing molar band is a time consuming process, failure with cemented molar bands were comparatively lower than bonded molar tubes. |
