title: Clinical Utilization of M Spring for the Space Closure of Midline Diastema - Clinical Case Reports.
abstract: People approach orthodontist mainly for aesthetic purpose, midline diastema is one of the condition which causes aesthetic compromise. The midline diastema can be caused by various reasons such as high frenal attachment, midline pathology, etc. In the field of orthodontics, relapse rate is high while treating midline diastema. This relapse can be reduced only when there is bodily movement of the incisors in mesial direction. In this article, two cases of midline diastema are selected. Both the cases were treated using "M" spring which has three coils; two at periphery and one at the center and each coil was of 3mm diameter. "M" spring was fabricated using round 0.018" AJ Wilcock wire for one case and 0.017 X 0.025 TMA for another case. For both cases the duration of treatment was for six weeks. IOPA was taken after six weeks, the case in which rectangular wire was used; there was bodily movement of the central incisor in mesial direction. Whereas in round wire technique, predominantly tipping type of tooth movement was seen. The rectangular wire has two point contacts, because of which bodily movement was obtained. This technique of using rectangular wire to fabricate "M" spring has less inventory and chair side time.
