Effect of post-processing on the surface, optical, mechanical, and dimensional properties of 3D-printed orthodontic clear retainers.

Objectives: To address the high surface roughness and poor optical properties of three-dimensional (3D) printed orthodontic clear retainers, an alternative post-processing protocol was investigated with the goal of achieving improved surface, optical, and mechanical properties while preserving dimensional accuracy.

The efficacy of facial skeletal treatment options in the management of obstructive sleep apnea.

Obstructive sleep apnea (OSA) is characterized by intermittent cessation of breathing during sleep due to the collapse of oropharyngeal tissues. This review examines the role of craniofacial growth in OSA and evaluates the efficacy of orthodontic and orthognathic treatments. Maxillary expansion and orthognathic surgery have demonstrated significant reductions in sleep apneas and hypopneas, although they do not consistently achieve cure levels, particularly in the presence of obesity and connective tissue disorders.
