“…The use of miniscrew has grown in popularity over the years because of its ability to provide absolute anchorage [10]. Distalization of the entire mandibular dentition is a viable way to correct a class III anteroposterior relationship (a negative overjet or an edge-to-edge occlusion) with miniscrews implanted in the MBS and dental and skeletal discrepancies of many patients could get dento-alveolar compensation [6].…”

“…Our results show that the mean values of the buccal alveolar bone and the inter-radicular space in the L6 db –L7 mb region were 6.39 mm and 4.97 mm at a plane of 9 mm, respectively, with wider measurements at planes < 9 mm. As a minimum of 1 mm of alveolar bone around the screw is sufficient for good periodontal health [10], and considering that the diameters of most miniscrews are 1.2 to 2.3 mm [10], we conclude that it is safe for miniscrews to be inserted in the L6 db –L7 mb region at and below a plane of 9 mm.…”

“…Due to the limitation in the number of samples, many factors that might affect the measurement of the MBS, such as ethnicity, vertical skeletal patterns, and gender, were not considered [19]. Moreover, the thickness and morphology of the soft tissue in the MBS should also be studied, because the mobility of the alveolar mucosa can affect long-term miniscrew stability [10]. As such, further experiments will be needed to confirm our findings.…”

BackgroundTo assess the anatomy of the mandibular buccal shelf (MBS) with cone-beam computed tomography (CBCT) and to identify the region of miniscrew implantation for the distalization of mandibular dentition.Materials and methodsThe MBS was assessed in 80 patients at four regions as follows: (i) between the buccal root of the mandibular second premolar and the mesiobuccal root of the first molar (L5b–L6mb), (ii) between the mesiodistal root of the first molar (L6mb–L6db), (iii) between the distobuccal root of the first molar and the mesiobuccal root of the second molar (L6db–L7mb), and (iv) between the mesiodistal roots of the second molar (L7mb–L7db). The buccal alveolar bone thickness, the narrowest inter-radicular space at the buccal side of the roots, and the distance between the implantation site and the mandibular neural tube were measured at horizontal planes of 3, 5, 7, and 9 mm from the alveolar crest.ResultsThe buccal alveolar bone thickness increased from the premolar to the molar and from the crest edge to the mandibular roots. The L7mb–L7db region had the thickest buccal alveolar bone of 7.61 mm at a plane of 9 mm. The buccal inter-radicular spaces were smallest in the L7mb–L7db region and greatest in the L6db–L7mb region. The distances from the implantation site to the mandibular neural tube at planes of 3, 5, 7, and 9 mm were all > 13 mm from the L6 region to the L7 region.ConclusionsThe L6db–L7mb region should be the first choice for miniscrew implantation in the MBS for the distalization of mandibular dentition.

“…Therefore, anodic oxidation is becoming a common procedure in manufacturing orthodontic miniscrews that carry a specific color according to their lengths. However, in spite of the commercial availability of miniscrews treated by anodic oxidation and their wide use in orthodontics [10], evidence on the biological effects of such a TiO 2 layer for orthodontic purposes is still scarce. Although the cellular response to TiO 2 has been investigated using a variety of cell types, including osteoblasts, fibroblasts, and chondrocytes (for review, see Ref.…”

This controlled in vitro study compared the effects of varying the thickness of a TiO2 layer on cellular activity using commercially available miniscrew samples with identical surface features to derive information with direct clinical impact. Titanium grade V plates with four different thicknesses of TiO2 layer/color were used: absent/gray (Control group), 40–50 nm/pink (Pink group), 130 nm/gold (Gold group) and 140 nm/rosé (Rosé group). In vitro experiments used Saos-2 cells and included cell growth analysis, phospho-Histone H3 and procollagen I staining, cell viability analysis, and a cell migration assay at 12, 24, 40 and to 48 h. Few differences were seen among the groups, with no clear behavior of cellular activity according to the TiO2 thickness. The Control group showed a greater cell count. Phospho-Histone H3 staining was similar among the groups and procollagen I staining was greater in the Rosé group. Cell viability analysis showed a significant difference for live cell counts (greater in the Rosé group) and no difference for the dead cell counts. The cell migration assay showed a delay for the Rosé group up to 40 h, where full repopulation of cell-free areas was obtained at 48 h. The results suggest that the TiO2 layers of the commercial miniscrews have minimal biological effects, including cytotoxicity, with possibly negligible or minimal clinical implications.

“…To overcome this, skeletal anchorage systems were devised. These include different variations of miniscrews [4] and miniplates. This article deals with the use of miniscrews for camouflage treatment of Class III malocclusions.…”

Class III malocclusions pose a challenge to the orthodontist, and conventional treatment options to treat this condition in an adult patient include orthognathic surgery, or orthodontic camouflage. Up until a few years ago, orthodontic camouflage for correction of a Class III problem involved retroclination of the lower anterior teeth and proclination of the upper anterior teeth. The advent of skeletal anchorage systems has opened up new vistas in camouflaging Class III malocclusion due to mandibular prognathism. This article reviews the various treatment planning considerations, both clinical and radiographic, for camouflage of Class III malocclusion by miniscrew assisted distalization of the mandibular dentition, and also discusses treatment options, procedures, biomechanics and possible pitfalls. www.adum.edu.my
