Developed by Dr. John T. Herald, Dental Ceramics Inc., has been fabricating the ZQuiet ProFlex for the past 5 years. This effective and compliant appliance has quickly become the most successful appliance Dental Ceramics has fabricated in their over 50 years of business. 

The ZQuiet Pro-Flex is an FDA-cleared, patient-friendly oral appliance for the treatment of snoring an mild-to-moderate
Obstructive Sleep Apnea (OSA). It gently opens the airway to permit unobstructed breathing. Its unique design features
widen the airway while minimizing the need to advance the mandible, enabling you to deliver a comfortable, effective
appliance while minimizing TMJ stress.


ZQuiet Pro-Flex The Right Appliance for your Patients. Safe and Effective Therapy without unnecessary Advancement of the Mandible.

Thermoplastic Dental Resin
The ZQuiet Pro-Flex appliance is made with a thermoplastic dental resin that is 100% monomer and nylon free, strong, flexible, and stain resistant. The material provides superior retention and comfort, and at mouth temperature loses rigidity to engage dental undercuts and provide an instant fit without the use of clasps, which results in greater patient comfort and better compliance.

Lingual Ramps Support Forward Tongue Positioning
Bilateral ramps on the lingual surface provide support and activate involuntary reflexes that facilitate the upward and forward position of the tongue creating greater pharyngeal space. Lingual ramps are especially helpful for patients with narrow arch forms or large tongues.

Patient-Specific Vertical Opening
The occlusal aspects on the mandibular orthotic are fashioned to increase the vertical inter-incisal dimension to further assist in dilating the upper airway. No single vertical dimension is appropriate for every individual, and the clinician can specify the vertical dimension to optimize performance for each patient. 

Open Anterior Space
The low profile design of the device components is minimally invasive allowing for maximum intra-oral space. There are no bulky hinges, posts, or mechanical hardware to interfere with the mouth opening or impede reflexive travel of the tongue.


Forward Angle Maintains Anterior Jaw Positioning
Stabilizing the muscles that attach to the hyoid helps maintain pharyngeal airway patency. The angle bias of the fin and buttress junction necessitates anterior movement of the condylar mechanism in the temporomandibular joint, therefore when the mouth opens the jaw must translate anteriority. The titrating screws located in the mandibular fin provide the capacity to individualize the anterior advancement of the mandible. Placement of the screw in the fin does not compromise tongue posture or impinge on the oral compartment.
