The user asked me to generate a dental care guide article for South Korea in Korean. I have gathered enough information about Korean dental costs (implants ₩800,000-2,800,000, scaling insurance coverage ~₩15,000-19,000 once a year), senior implant coverage (30% co-payment for 65+), dental checkup statistics, and regional resources. Now I will write the article in Korean following all the format requirements.
