So for maxillary protraction the best non surgical option available now is bollard miniplates right? However they are not very stable under high loads because the screws are very short. AFAIK they are like 5mm in lenght. This is for miniplates that are installed on infrazygomatic crest
However there is another type of bollard miniplates that are used and these ones are placed on lateral nasal walls. So the issue with bollard plates placed on infrazygomatic crest is that if you go beyond a certain lenght, there is a risk of serious sinus infection because those screws are not supposed to enter onto the sinus cavity. However this problem does not exist with the nasal cavity. For example, MSE screws are actually supposed to penetrate onto the nasal cavity for better chances of skeletal expansion. That is what makes MSE more succesful than other types of MARPE. So why would it be an issue to use longer screws on lateral walls of the nasal cavity with miniplates? Since they cannot enter onto the sinus cavity, wouldn't using longer and more stable screws be more beneficial? Even if they actually enter onto the nasal cavity it won't cause an issue right? That would make miniplates much more stable for higher force loading purposes. Opinions?
