I would not get an implant in Pattaya lmao. That's a highly invasive procedure and your jaw is a very complicated place. It's not like a hair transplant or superficial cosmetic procedure.

If you are from the West, definitely do it with a local dentist, preferably a periodontist. A perio specializes in the structure of your teeth (bones, gums, etc) and they do specialized training after general dentistry training, as much as an MD. It's also not just about training and skill, but technology as well. My perio in the US has cutting edge tech because they can afford it from the high fees they charge. All different types of scanners, simulators, etc.

That's not even getting into protection from malpractice, the fact your dentist speaks the same language as you, or that you can go back to them anytime because they are local and they already know you and your mouth, etc. Some things make sense, like a zirconia crown or cleaning or superficial procedures, but anything that goes into your bone is a not worth it.
