Hi Misszambrano, No two Class III malocclusions are the same. Some Class III problems are caused by incorrect positioning of the teeth which means that the appropriate therapy should be focused on the teeth (i.e. braces, Invisalign) alone. More severe Class III problems are typically caused by jaw malposition which necessitate jaw surgery (upper, lower or combination of the two). In these cases, orthodontic alignment of the teeth is required prior to surgery so that the teeth fit together properly once the jaws have been properly aligned. Your best bet is to seek out the opinion of an orthodontist who can provide you with your treatment options. Best of luck!
