Comparative mechanical testing for different orthodontic aligner materials over time : in vitro study

The purpose of the present study is to mechanically evaluate and compare the forces over 12 hours on different orthodontic aligners manufactured by Polyethylene terephthalate glycol (PETG). Twelve orthodontic aligner specimens will be produced by a the

Mechanical evaluation for three-dimensional printed orthodontic springs with different heights-in vitro study

The orthodontic spring materials in use have a significant influence on the applied forces. The prerequisite to identify the in vitro force deflection of the CAD/CAM fabricated springs is considered mandatory to identify the material charact

Fracture strength test of digitally produced ceramic-filled and unfilled dental resin restorations via 3d printing : an in vitro study

Purpose of this study was to investigate the mechanical efficiency of 3D-printed permanent and provisional implant cemented fixed bridges produced via CAD/CAM technology using an interim and a permanent ceramic filled hybrid material. Two groups with t
