Abstract
To assess bone thickness for miniscrew placement in the mandible during mixed dentition by using digital volumetric tomograph (DVT).
A total of 15 healthy patients aged 8-10 years old, with early exfoliated mandibular second deciduous molar, were included. DVT images of one quadrant of the mandible were obtained using Kodak extraoral imaging systems and analyzed by Kodak dental imaging software. The error of the method (EM) was calculated using Dahlberg's formula. Mean and standard deviation were calculated at 6 and 8 mm from the cementoenamel junction (CEJ).Paired t-test was used to analyze the measurements.
Buccal cortical bone thickness, mesiodistal width and buccolingual bone depth at 6 mm were found to be 1.73 + 0.41, 2.15 + 0.49 and 13.18 + 1.22 mm, respectively; while at 8 mm measurements were 2.42 + 0.34, 2.48 + 0.33 and 13.65 + 1.25 mm, respectively. EM for buccal cortical bone thickness, mesiodistal width and buccolingual bone depth was 0.58, 0.40 and 0.48, respectively. The difference in measurement at 6 and 8 mm for buccal cortical plate thickness (P < 0.05) and buccolingual bone thickness (P < 0.05) was found to be significant, whereas for mesiodistal width it was insignificant (P > 0.05).
Bone thickness measurement has shown promising evidence for safe placement of miniscrews in the mandible during mixed dentition. The use of miniscrew is the best alternative, even in younger patients.

(p < 0,05) e a espessura óssea vestibulolingual (p < 0,05) foi
significativa, embora não tenha sido significativa para a largura mesiodistal (p
< 0,05). </p></sec><sec><title>CONCLUSÃO:</title><p> a mensuração da espessura óssea demonstra evidências promissoras para a segura
instalação de mini-implantes na arcada inferior e na fase de dentição mista. O uso
de mini-implantes tem se mostrado a melhor alternativa, mesmo nos casos de
pacientes mais jovens. </p></sec></trans-abstract><kwd-group><kwd>Miniscrews</kwd><kwd>Digital volumetric tomograph</kwd><kwd>Inter-radicular bone</kwd><kwd>Cortical bone</kwd></kwd-group><counts><fig-count count="5"></fig-count><table-count count="3"></table-count><equation-count count="0"></equation-count><ref-count count="34"></ref-count><page-count count="6"></page-count></counts></article-meta></front></pmc><affiliations><list><country><li>Inde</li></country></list><tree><country name="Inde"><noRegion><name sortKey="Bhattad, Mayur S" sort="Bhattad, Mayur S" uniqKey="Bhattad M" first="Mayur S." last="Bhattad">Mayur S.
