should I get a orthodonic mara appliance to fix overbite?

[sdfgsdfgsdfgds]

im already planning on getting Invisalign to fix my teeth (they arent horrible i just have slight spacing issues) but i also have an overbite. ive been offered to get a mara appliance which should help with the overbite issue and apparently reposition my jaw/give me forward growth if im not mistaken. i dont know much about ortho so i was hoping i could get some insight here; is getting this appliance going to be beneficial in terms of looks?
