Comparison of Intrusive Effects of Miniscrews and Utility Arch and Their Effects on Root Resorption
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 9
Abstract
Objective: To investigate the amount of incisor intrusion obtained by two intrusion mechanics including utility arch and miniscrews. Also, to compare the amount of root resorption noticed during active intrusion phase. Materials and Methods: The patients were divided into 2 groups. In Group 1, intrusion was carried out by using miniscrews; in Group 2, intrusion was carried out by using utility arch. In Group 1, brackets were bonded to the 4 maxillary incisors only and the teeth were leveled with nickel-titanium wires. Two miniscrews were placed distal to the maxillary lateral incisors and intrusion was carried out by closed coil springs. In Group 2, upper incisors and molars were involved and after initial leveling and alignment a passive preformed nickel-titanium utility arch was inserted followed by custom-made Rickett’s TMA utility arch. Radiographic grid was used for assessment of root resorption during active intrusion. Results: The results of present study proved that intrusion has occurred in both miniscrew as well as utility arch groups but comparatively no significant difference was found in amount of intrusion. Conclusion: Both miniscrew and utility arch are equally effective in carrying out intrusion of upper incisors but greater amount of root resorption was seen in utility group compared to miniscrew group.
