What is the ACG System? The ACG™ Airway Centric® System is the first fully integrated day and night oral appliance approach to solving airway issues by integrating Airway and Sleep with TMJ. The system includes six appliances that complement the traditional ProSomnus [IA] Platform.
Common daytime complaints related to the airway include fatigue, difficulty concentrating, mood disorders, acid reflux, headaches and high blood pressure. The day appliances help to balance the nervous system and reduce pain while opening the airway. The system focuses on improving performance and energy levels while decreasing these symptoms.
Opening the airway by advancing the mandible also functions to:
- Alleviate clicking, popping and locking
- Alleviate daytime clenching and reminding the patient to keep the lips together, teeth apart (LTTA) as a cognitive behavioral device
- Relax the masticatory and cervical muscles
- Improve heart rate variability and balance the automatic nervous system
- Create an aesthetic transformation
- Improve lower third facial height, increase lips, and better the chin
- “Non- surgical facelift”
- Improve nasolabial folds
- Correct facial asymmetry, placing the chin back to the middle of the face
The ACG™ Day is a lower milled repositioning device which covers the canines and establishes canine guidance while opening the airway during the day. It involves no clasps and is thinner lingually, allowing better speech which is essential for a daytime appliance. In addition, covering the canines and the lingual ribbon of milled PMMA prevents the intrusion of teeth.
ACG™ Day Full
The ACG™ Day Full is intended for patients with an anterior open bite. This lower repositioning appliance with full coverage establishes anterior contact and anterior guidance all while opening the airway. It transfers the bite force from the posterior teeth to the anterior teeth, which in a class 3 lever system relaxes the masticatory muscles.
ACG™ Functional (Juvabite®)
The ACG™ Functional is a lower anatomic device taken in an airway and TMJ friendly bite. This appliance is often prescribed after treatment with an ACG™ Day or ACG™ Day Full as a transitional appliance prior to restorative dentistry. For patients who may require a less bulky anatomic appliance capable of light chewing and clearer speech, this is an excellent option. While opening the airway and decompressing the TMJ, the ACG™ Functional also restores the lower third of the face for transformative aesthetic effects.
ACG™ Night Appliances
The main focus of the night appliances is to alleviate obstructive sleep apnea (OSA) and snoring and improve oxygenation, promoting more restorative sleep. These appliances stop the lower jaw from dropping back at night, preventing a collapse of the airway during sleep.
The ACG™ Night appliance is an anti-retrusion appliance with either the same repositioning bite as the ACG™ Day or a slightly increased vertical and protrusive bite. The anterior guide ramp prevents the jaw from retruding.
The ACG™ Night is indicated for individuals presenting with TMJ complains prior to using the ProSomnus [IA] or HERS.
ACG™ Lower Retainer
The ACG™ Retainer was added to the system in response to three occasional issues:
- Discomfort of the lower anterior teeth in the morning following nighttime clenching against the anti-retrusion ramp
- Mobility of the lower anterior teeth with short conical roots following trauma against the anti-retrusion ramp
- Shifting and crowding of the lower anterior teeth
The ACP Position Paper on Oral Devices points out recent research demonstrating that traditional flat plane nightguards often close the airway and worsen OSA and snoring. To avoid liability, the dentist needs to use a different device with the bite taken in a more protruded jaw position. The ACG™ Brux-Pad is an excellent option for the patient to stop bruxing without closing the airway. All dentists are advised to screen bruxism patients for airway and sleep disorders. If a disorder is found, the patient may be upgraded to a ProSomnus IA or ACG™ HERS.
ACG™ Select IA
The ACG™ Select IA was designed for women and men with smaller mouths and large tongues who are not able to tolerate other sleep and airway appliances. Lip seal is accomplished by thinning the labial surfaces and decreasing vertical dimension. The lingual-less design also enhances treatment efficacy.
