Where would be a good place in the Bupyeong area for my mother's dental implants?

My mother is seventy-four this year, and her upper teeth are in very bad condition.
I was told that my alveolar bone is still in good enough condition for dentures, so I am looking into implants.
I searched for dental clinics in the Bupyeong area online, and I found that Plan Dental Clinic had some reviews.
But since my mother is getting older, I want to do it at a place with a lot of experience.
If you happen to know of a good place in Bupyeong for elderly implants, please let me know.
thank you
