How do I correct a massive overbite? Would I have to get a full mouth reconstruction and jaw surgery? (photos)

I have a massive overbite and gum disease. I have 3 teeth missing from my upper jaw. I'm 32 yrs old. My Dentist said there's no point in me getting braces b/c all my teeth will probably fall out in 20 years but I can get implants to replace my missing teeth.
