Objective To investigate alterations in the mechanical properties of in-house three-
dimensional (3D) printed orthodontic aligners after intraoral ageing. Materials and methods …

Objective: To assess the surface roughness of in-house 3D-printed orthodontic aligners
compared with Invisalign® appliances, both retrieved as well as in the 'as-received'control …

Introduction Orthodontic treatment using clear aligners has experienced exponential growth
since its introduction in the late 1990s. Three-dimensional (3D) printing has also grown in …

Objective The aim of this study was to compare the mechanical properties of orthodontic
aligners among different commercially available 3D printing devices. Materials and Methods …

Background Based on the role of properties of aligner materials on their efficiency, we aimed
to assess their thermomechanical properties after thermoforming and simulated aging …

Introduction This study aimed to investigate the effect of digitally designed aligner thickness
on the thickness of the corresponding 3-dimensional (3D)-printed aligner. Methods Digitally …

Objectives To assess the scientific evidence related to the alterations in surface morphology,
chemical and mechanical properties of clear aligners during intraoral usage. Materials and …

Orthodontics stands on a junction where traditional analog appliance manufacturing slowly
but steadily changes to a digital one with the use of 3D technology. The main cause of this …

Clear aligner orthodontic treatment is not a new treatment modality. Treatment with the use
of plastic invisible removable appliances counts more than 80 years when Kesling …
