“…Usmani et al 3 observed the retroinclination of upper incisors with canine lacebacks. However, Irvine et al 4 found that canine laceback ligatures convey no differences in the anteroposterior position of the lower labial segment. In our study, two different force systems were used along the same arch wire.…”

Objective: To evaluate the effects of laceback ligatures on canine distalization during the leveling and aligning stage and to compare the effectiveness of laceback ligatures with that of superelastic NiTi closed coil springs. Materials and Methods: Fifteen subjects were included in this study. Fixed orthodontic treatment was planned with the extraction of first premolars to solve crowding in upper and/or lower arches. Stainless steel direct-bonding Roth brackets (0.022-inch) were used. For canine distalization superelastic NiTi closed coil springs generating 150 g of force were used on one side. Lacebacks made from 0.010-inch ligature wire were applied on the contralateral side. Dental and skeletal changes were evaluated from predistalization and postdistalization lateral cephalometric and submento vertical radiographs. A Wilcoxon test was applied to determine the differences between predistalization and postdistalization mean values and to determine the mean differences between the groups. Results: Upper incisor crowns moved posteriorly. Distal movement and tipping of the canines were significant for both groups. Likewise, mesial movement and tipping of the first molars were significant for both groups. Furthermore, distopalatinal rotation of the canines was significant in the coil group. Canine and molar movements were greater for the coil group than for the laceback group, and the differences were significant. These differences may be attributed to force characterization, as well as to arch wire size and material. Conclusion: The laceback ligatures proved to be effective for canine distalization. Less canine and molar movement was found for the laceback group, but more controlled movements were obtained for the sagittal, vertical, and transverse planes.

“…[2][3][4] In two studies, the anteroposterior position of lower incisors was evaluated during the leveling and aligning stages. 2,4 Usmani et al 3 evaluated the anteroposterior position of upper incisors. However, a literature search showed that the effectiveness of lacebacks on canine distalization has not yet been investigated.…”

“…In a randomized controlled clinical trial investigating the effectiveness of the laceback ligatures showed no statistical or clinical difference in the anteroposterior or vertical position of the lower labial segment or in the relief of labial segment crowding and the use of laceback ligatures creates a statistically and clinically significant increase in the loss of posterior anchorage, through mesial movement of the lower first molars [9]. In our case report, the laceback was used not in the way that McLaughlin and Bennett were intended but to apply gentle force to close the bony defect.…”

IntroductionPrevalence of complications from orthognathic surgery is relatively low but if it happens it is vital to manage the post complication bony defect appropriately.Case PresentationThis case report describes a 20-year-old gentleman who suffered from a complication from a bimaxillary orthognathic surgery. A bone grafting was carried out to repair the bony defect from the surgery but it was unsuccessful. A non-invasive technique employing the use of very light orthodontic force with a laceback stainless steel ligature is described and a successful space closure with an improvement in the periodontal condition and bone apposition has been shown.ConclusionThis technique can be considered if orthodontic tooth movement is needed across a deficient alveolar ridge.

“…In a clinical control trial, canine lacebacks were found to prevent lower labial segment proclination in the order of 2.5 mm (19). However, it should be noted that the use of lacebacks have been questioned with a randomised control trial finding no difference of canine lacebacks to prevent lower incisor proclination but found a statistically significant difference of more mesial movement of the molars (20). Thus, in order to reduce the amount of mesial movement of the molars, the lower second molars were also included in the canine lacebacks to increase the posterior anchorage.…”

A late adolescent patient presented with a Class III malocclusion on a skeletal Class III base, complicated by severe upper arch and moderate lower arch crowding, reverse overjet, anterior and bilateral posterior crossbites with displacement, proclined upper incisors, retroclined lower incisors, distally tipped lower canines and non-coincident centrelines. Treatment was undertaken on an extraction basis by employing the use of an upper removable appliance with Z-springs and posterior bite blocks to correct the anterior crossbite, quad helix and jockey arch for arch expansion, and pre-adjusted edgewise fixed appliance to level and align, space closure and achieve a mutually protective functional occlusion. This paper discussed the rational and evidences behind the treatment employed.
