Thanks FuryuX,
The jaw sliding is what I was refering to.
But any more I see more and more pro fighters with the single mouth piece, which allows for soooo much more oxygen intake.
I've found that the normal doubles are too thin to protect
against hard punches, even with heavy gloves. I've had my
teeth chipped after getting punched in the mouth when I was
wearing my WIPPS mouthpiece.
However, I still like it because it really forces me to keep my
mouth clenched. I wish I could find a custom made, thicker,
double.
Does anyone know of a place to get a custom double?
I use a single and have never had any problems. Mostly because I get punched in the nose instead of the jaw or mouth. Sadly the nose I have now is not the one I was born with.
I prefer single for various reasons, foremost being the aforementioned increase in breathing capacity. A single is also less likely to fall out when you open your mouth, or at least it is for me. And the double requires you to constantly bite down on the piece which IMO isn't always the best thing to do.
properly fitted mouthguards produce a separation between the head of the condyle and the base of the skull. This space supplies the increased distance necessary to reduce acceleration, reducing the force of impact during a blow and thus reducing the impact of those forces on the brain and reducing trauma. This occurs with both double as well as single mouthguards that have been fitted properly. If you think of the jaw as a door and you place a pencil in the jam close to the hinge, you will find that the door is held open several feet. It is the thickness over the back teeth (recomended to be at least 4mm) that creates the seperation at the head of the condyle in a single. In the WIPPS type of design the lower part of the guard is set slightly ahead of the upper to create the seperation but tend to lack enough thickness to protect from blows to the mouth.
