A lot of people in this space talk about wanting to achieve CCW rotation through "natural" methods, and most of these are obviously copes but if you truly believe they work you should be chewing, not mewing. Based on a study of a 3-D computational model of a 10-year-old girl's craniofacial skeleton from CBCT imaging where they applied simulated 10 N vertical forces to different locations along the palate we can see a very interesting relation between where force is applied vs the rotation it triggers:
In theory, even if mewing applied a continous downward force of 10N to the maxilla, this still wouldn't result in any significant CCW rotation in most regular people. Why? Well, there are many reasons. First of all, the tongue is way too spread out unlike the 10N of force in the study that was concentrated on a single point, and second of all, most people already apply a similar amount of force to their maxilla. Even if you don't "mew", you probably don't rest your tongue at the bottom of your palate, so you're not really meaningfully changing the amount of force being applied to your maxilla by consciously doing it.
This is where chewing comes in, the average person can produce a MASSIVE amount of force by chewing, around 100-200N, but the thing is, most people go about doing this in the wrong way. In general, if you want any skeletal changes, you need to apply force for at least 10 hrs or more a day, you can't just apply a massive amount of force for 5 minutes and then no force for the rest of the day and expect skeletal changes. So, I think a better alternative to mewing is continuousy chewing on back molars since it applies way more force and it should in theory produce way better results.
- 40 mm anterior to PNS: ↓ → CW
- 30 mm anterior: ↓ → slight CW
- ~20 mm anterior: ↓ → mostly translation
- 10 mm anterior: ↓ → CCW
- PNS itself: ↓ → strongest CCW
