How to improve my facial proportions? Considering genioplasty or chin implant

Hi, as the title says, i would like to improve the proportions on my face. I am not sure what is the right procedure here. Is it genioplasty/chin implant? I would like to improve the height of my chin, to make it longer. I also have a slight overbite, so maybe the dental braces would help? Since this would be my first procedure i don't know nothing about those. (For example difference between genioplasty and chin implant and which one of those can make my chin longer). Thanks
