Efficacy of Different Treatments for Obstructive Sleep Apnea

With a vacuum mahine (Biostar, NY) a 2-mm-thick hard, clear resin sheet was adapted to the cast. The excess material was cut, borders were trimmed and smoothed. Maxillary mandibular casts were mounted by a protrusive the interocclusal record. The appliances were re-placed on the mounted casts to be splinted to form a Monoblock MAD by autopolymerizing acrylic resin at the premolar -molar area.

"3D models for the stone casts were constructed with laser scanning machine (accuracy \<20 µm; D500, 3shape).~Maxillary and mandibular casts were rescanned in the achieved 75% advancement position and monoblock device was designed by CAD (computer-aided design) with 3D software (3-matic; Materialise) and printed by"

uvulopalatopharyngeoplasty UPPP were performed by the same ENT surgeon under GA.
