Mechanical Properties of 3D Printed Orthodontic Aligners Produced by Different Commercially Available Printers - An Study.

The aim of this study was to compare the mechanical properties of orthodontic aligners among different commercially available 3D printing devices. Three different 3D printers were included in this study (Formlabs Form 2 3D printer; Moonray S100 printer (Sprintray, Los Angeles, CA, USA); Eden500V Stratasys 3D Printers were used to prepare orthodontic aligners with dental. The central incisors of each aligner were cut, prepared, and evaluated in terms of Martens-Hardness (HM), indentation-modulus (E), and elastic-index (η) as per ISO14577-1:2002.

Effect of Three-wall Bony Defect along Various Root Surfaces on Position of Center of Resistance: A 3D Finite Element Analysis.

Introduction: Increase in adult orthodontic patients has increased the challenges faced by orthodontists, as they often present themselves with a varying degree of dental and peri-odontal compromise, in which the entire orthodontic treatment planning will revolve around maintenance and augmentation of supporting apparatus. One of the many factors to be considered during treating an adult patient is the height of alveolar bone and its effect on center of resistance (CRes).

Materials And Methods: Eight 3D analytical models of upper central incisor were designed using 'Solid Works Office Premium'.
