it is the same guy
dr Y and one of my local surgeons wrote a paper on alloplastic implants as an adjunct to orthognathic surgery (i think that was the title verbatim) There are very few cases where this is actually a good option. unfortunately, if you go to a surgeon who specializes in implants, youre going to get recommended implants, even if you need orthognathic surgery.
its horrible. tons of people get chin implants when they needed a bsso. it looks outrageously bad.
