Glidewell launches digital Silent Nite 3D Sleep Appliance

Silent Nite 3D is a mandibular advancement device that has evolved from earlier generations of Glidewell’s Silent Nite Sleep Appliance. Fabricated from durable light-cured resin, the appliance treats patients who suffer from snoring and mild to moderate obstructive sleep apnoea (OSA).

According to the company, the clear, custom-fit appliances gently shift the mandible forward, using nylon connectors adjustable in 0.5mm increments over a 10mm span, and open up the airway to prevent it from collapsing during sleep.

These connectors are replaceable, which allows dentists to adjust the position of the mandible to ensure the patient is receiving proper care while remaining comfortable. The scalloped edge of the appliance, which is achieved with the 3D-printing method, increases retention with minimal contact to the patient’s gingiva. This design aims to make the appliance ideal for patients to use at home or while traveling, lightweight, and easy to store, to provide a user’s with a good night’s sleep anywhere.

“Glidewell is committed to the digital transformation of dentistry – both in the lab and chairside. Digital dentistry makes quality care more accessible for dentists and patients alike, and the Silent Nite 3D Sleep Appliance is a patient-friendly, digitally produced solution for relieving snoring and mild to moderate sleep apnoea,” said Robert Brenneise, chief growth officer at Glidewell.

The company added that according to the National Council on Aging (NCOA), approximately 39 million adults in the US suffer from sleep apnoea.1 The new device from Glidewell can alleviate symptoms of sleep apnoea and give patients the rest they deserve. Dentists may also order a duplicate of the same case to be included as part of a Glidewell Clincial Twinpak.
