You don't need a specialist oral surgeon. Find a good local implant dentist who can take care of you. bring your radiograph and they can give you a treatment pplan and will know good specialists they can refer you to if necessary.
looking at your options - under no circumstances consider veneers at your age. I'm not going into this on a forum like this but find a local dentist to you who can explain this. If they want to place veneers, simply run! If you have any form of ortho then you will have to wear retainers. These can be bonded to the back of your teeth ie permanent. Get an orthodontic opinion and you will be likely surprised with how little time your case may take. filing down your teeth is not a good option. Disguising the irregularity can be done with bonding composite,. This is relatively harmless and reversible. It will keep the door open to orthodontics later in life but there is never a good time to be weariing braces and if really needed I think the earlier the better.
Find good implant dentist on ICOI database and you will need diagnosis first which means quailified Dr's eamining you and doing special investigations with radiographs etc. Nobody wants to do bone grafting if it is not necessary so ask around in your area. Nowadays I'm sure your direct circle of friends and relatives know of reputable implant dentists you can see.
Bone can be regenerated and it seems a shame you went all the way to Hungary without a diagnosis and treatment plan. This would not be satisfactory at home where you live but having to travel all the way to central Europe first before you are fully aware of the situation is even less satisfactory. Dental implants and reconstructions are like house building in a way and patients with the internet and adverts available are always asking how much does it cost and how long will it take? without actually knowing what it is they are getting into. Hopefully your question will help others think first to find out where they are in planning terms before booking their flights! It should not be too difficult to find a dentist for an opinion, in the UK where our practice is, the ADI (and internationally the ICOI) have a good database to work from. Share your scan and photographs/radiographs please and you may even get some specific opinions on this forum. Good luck with your case, Reg O'Neill
You need an orthodontist opinion, find one by asking around where you live or get referred by your dentist.
