“…According to the study by Migliorati et al, by using the direct anchorage, the canine showed a 1 mm/month movement speed rate for the root apex and slightly faster movement in terms of cusp movement when compared to the use of the indirect [19,20]. The single-TAD approach is impressive and simple to handle, but it should be noted that some authors prefer the use of two-TAD technique to reduce any stability problems due to traction activation [21][22][23].…”

This paper aims to represent the orthodontic treatment of two young patients with skeletal Class I relationship and unilateral impacted canines (case 1 with palatally displaced canine and case 2 with buccally displaced canine). Before starting full-mouth alignment, canines are moved away from the roots of the neighbouring teeth. The protocol involved a surgical phase carried out in order to expose the canine and traction it with TADs (temporary anchorage devices) and an orthodontic phase performed to finalize the alignment. The canines were moved through vertical and distal force vectors by using TADs as well as a cantilever spring. As soon as the crown of the canine was fully visible, digital impressions were taken to start the digital planning of the orthodontic phase. At the end of the treatment, results show a control of the facial aesthetics both from the frontal and lateral perspectives with a harmonious profile. The molar and canine Class I relationship was achieved with the recovery of the impacted canines and the overbite and overjet were normalized.

“…Skeletal anchorage allowed the tooth movement, without stressing the anchorage of the posterior teeth. The simplicity of the approach make the segmented method a good alternative in the treatment of canine impaction [ 26 ].The cantilever can be also attached both to the anchorage tooth unit and to the TAD, as a multi-attachment appliance. Insertion in the auxillary tube of a molar aids to reduce the moment acting on the head of the screw [ 11 ].…”

Cantilevers: Multi-Tool in Orthodontic Treatment

2022

This review aims to discuss and illustrate various uses of cantilevers to solve multiple clinical issues and prove their versatility. Cantilevers are commonly used in the segmented arch technique, and they can be designed to solve various clinical problems with highly predictable results. Its design and shape can modify the various combinations of vertical and horizontal forces. The novel trend is to combine cantilevers with skeletal anchorage. Cantilevers offer a very simple and statically determined force system. The advantage is the control over side effects, which normally occur on the anchor teeth and the occlusion. The disadvantages include possible side effects on the anchorage unit, when the anchorage is poorly controlled. The review highlights the clear benefits of cantilever use in complex corrections of single teeth, segments, and entire arch with a diminished effect on the dentition, also with the use of skeletal anchorage. With their simple and easily tailored design, these springs can be called an orthodontic multi-tool.

“…All of the TPAs were produced using the SLM technique, resulting in a more rigid structure in comparison to traditional TPAs. The single-miniscrew approach is noteworthy and simple to manage, but it should be noted that some authors prefer the use of two miniscrews to reduce any stability issues due to the activation of the traction [10].…”

“…In any case, proper anchorage preparation and management are key factors for efficient canine movement and reducing undesirable changes in the posterior teeth. Skeletal anchorage has been proposed to increase the stability of anchorage unity and to solve canine impaction alone [9], or along with other appliances such as brackets or aligners [10][11][12]. Miniscrews can be placed either in the inter-radicular space or, alternatively, in the paramedian area of the palate, where high success rates and effectiveness of treatment have been documented [13].…”

Treatment of Palatally Displaced Canines Using Miniscrews for Direct or Indirect Anchorage: A Three-Dimensional Prospective Cohort Study on Tooth Movement Speed

et al. 2022

Palatally impacted canines are usually challenging to treat in terms of both biomechanics and possible side effects. Different therapeutic approaches have been reported with or without the use of temporary anchorage devices, including the canine-first approach. Two groups of patients with palatally impacted canines were compared, observing their canine movement measured on consecutive CBCTs after three months of treatment. In the control group, impacted canines were treated with direct anchorage on miniscrews, and in the test group with indirect anchorage using a miniscrew-supported transpalatal arch. The primary outcome was the canine movement speed; the secondary outcome was the change in the root length of adjacent teeth. The median monthly apex speed was 1.05 mm in the control group (IR [0.74, 1.64]) and 0.72 mm in the test group (IR [0.27, 1.30]). The median monthly cusp displacement was 1.89 mm in the control group (IR [1.04, 2.84]) and 1.08 mm in the test group (IR [0.81, 1.91]). Approximately 50% of teeth adjacent to an impacted canine underwent a negative root length change of less than 1 mm in the majority of cases, but no significant differences were found in root length changes between groups. No statistically significant differences in the reported speeds were found, and no miniscrew failures were observed in either group.
