A Comparative study of Resistance during Tooth Retraction Using Ceramic Bracket and Ceramic Bracket with Metal Slot: In-Vitro Study
Frictional resistance is an important counterforce to orthodontic tooth movement during sliding mechanics. This study was carried out to evaluate the effect of ceramic bracket and ceramic bracket with metal slot -archwire‐ ligation combinations on “resistance to sliding” during simulated canine retraction on typodont model. The frictional resistance was tested between Ceramic brackets (3MUNITEK...

15 صفحه اولTranslucency of Dental Ceramic, Post and Bracket
Translucency of dental ceramics, esthetic posts and orthodontic brackets was reviewed. Translucency parameter (TP) and contrast ratio (CR) are generally used for translucency evaluation. For the evaluation of translucency, two criteria such as the translucency of human teeth (TP = 15-19, 1 mm thick) and the visual perceptibility threshold for the translucency difference (∆CR > 0.07 or ∆TP > 2) ...
