I think the reasons are complex for not getting both implants at once. It’s absolutely doable and there was a study done quite a few years ago that showed it was a viable approach. In general, there’s a tendency to avoid doing bilateral surgeries of anything. There’s a chance if something goes wrong, it could affect both sides. Recovery is usually longer and more challenging, but it basically comes down to inertia, meaning they do it that way because that’s the way they’ve always done it. I don’t think money factors in consciously, but I do think the incentives are wrong.
