Further brilliant innovation in design,
The latest superb iteration of the acclaimed Munchies range, have now been designed to optimize the seating of aligners in the premolar region in particular, where expansion is often programmed. Designed and engineered by the Orthodontic Faculty at the Postgraduate School of Dentistry, this device utilizes the same principle as the original Munchies but also focuses on the posterior teeth, whereby optimization of seating and fit ensures that pre-programmed forces built in to the aligners are delivered accurately.
Intimacy of fit means accuracy of Force Delivery
For the most predictable tooth movements to occur, an intimate fit of the aligner is required after each re-insertion, especially at the gingival margin. This ensures that the pre-programmed force systems built into the aligners are delivered correctly. When the devices are repositioned using finger pressure alone, aligners can slip up to 10% of the length of the clinical crown. If the aligners are not fully seated, forces can be delivered aberrantly, causing unwanted movements which severely disrupt the predictability of treatments. Using the 4 Point Touch System design, the Munchies EPS posterior arm engages the aligner in the central fossa and cuspal inclines areas of the premolars and optimizes seating without compromising the shape of the aligner.
Minimise Tipping and Open Posterior Bites
Munchies EPS have also been designed to minimize unwanted tipping movements during arch expansion, especially in the premolar region. These tipping movements occur due to the expansion forces programmed into the aligners being applied inaccurately. Poorly fitting aligners in the premolar region will deliver forces which are too coronal and produce a greater propensity to unwanted tipping and onerous open posterior bites.
The Munchies EPS 3-ridged-arm has been designed to adapt to the anatomy of all premolars and extended palatally and lingually to ensure expansion forces from the aligners are delivered as gingivally as possible to avoid tipping and open posterior bites.
Medical grade silicone even stronger
Munchies EPS are engineered using a new patented medical grade silicone material (MVT - Munchie Viscoelastic Technology) with improved tear strength and superior mechanical properties. Patients using the EPS Munchies all report an instantaneous improvement in the fit of their aligners.
Munchies EPS are offered in Pink and Blue colours. The Pink option has a hardness in between the standard Yellow and Orange Munchie, whilst the Blue option has a similar hardness to the standard Red Munchie. A pack of 6 (which includes 3 Pink and 3 Blue Munchies EPS and 2 carrying cases) is ideal for each patient, with a busy practice having the option of buying in bulk packs.
Indications for Use
Standard Munchies can be used in simple cases with minimal posterior movements and limited expansion.
Munchies EPS are ideally prescribed for treatment plans:
- With more than 1mm expansion per quadrant
- Where sagittal plane movements are planned
- Vertical anterior movements are required (both intrusion and extrusion) to ensure ideal posterior anchorage
To optimise seating, after aligners are re-inserted each time, 30 seconds engagement and chewing with the EPS arm positioned in the premolar region in both posterior quadrants is ideal. Similar chewing in the anterior grooved arms, (both maxillary and mandibular) is then indicated.
To optimise the prescribed tooth movements, additional engagement and chewing using each arm for up to 10 minutes per day is ideal and patients should be encouraged to follow this protocol on a daily basis.
