Zirconia-Glass frit 조성에서 MgO 및 착색료가 소결체의 색상 변화에 미치는 영향

권은자(Kwon, Eun-Ja),최에스더(Choi, Esther),이규선(Lee, Kyu-Sun),이채현(Lee, Chae-Hyun) 한국산학기술학회 2009 한국산학기술학회논문지 Vol.10 No.8

지르코니아(3Y-ZrO₂)에 frit을 첨가하고 MgO를 조제로 첨가하거나 혹은 하소된 성형체에 액상의 착색료에 침지하 는 방법을 통하여 착색하고 얻어진 소결체의 물성과 색상 변화를 고찰하였다. Frit가 20 wt% 첨가된 지르코니아-frit조성에 MgO가 첨가됨에 따른 색상의 변화는 소결온도가 높아짐에 따라 구별가능한 정도로 효과가 있음을 확인하였다. 이 때 색상의 변화 정도는 MgO의 첨가량 변화에 의한 효과 보다는 소결 온도의 변화에 의한 효과가 더 크게 나타났음을 확인할 수 있었다. 액상의 착색료에 침지한 후 소결한 경우에서는 frit의 첨가량이 증가함에 따라 반사도가 증가하는 것으로 나타 났으며 착색료에 침지하지 않은 경우에 비하여 색상의 변화가 감소함을 알 수 있었고 frit은 색상의 변화를 억제하는 것으 로 나타났다. The effects of MgO and coloring agents on the physical properties and color of zirconia based ceramics with glass frit were studied. The addition of MgO was effective on the coloring of zirconia-20wt% glass frit system. Major factor on the coloring was turned out to be sintering temperature. Coloring agents was turned out to be more effective than the addition of MgO on the coloring of zirconia base ceramics. Specimen without glass frit showed drastic change in color, while specimen with 20wt% glass frit revealed a limited change in color. This means that the addition of glass frit suppresses the coloring of zirconia based ceramics. The effect of sintering temperature on coloring revealed little change in color.

한민수,권은자,최에스더,Han, Min Soo,Kwon, Eun Ja,Choi, Esther Korean Academy of Dental Technology 2021 대한치과기공학회지 Vol.43 No.3

Purpose: This study aimed to investigate the perception of dental implant insurance supply and demand for the elderly living in Hongseong-gun and Chungcheongnam-do, as well as the selection criteria regarding dental clinics for dental implant treatment to collect basic data for improving the oral health of the elderly population. Methods: Participants living in Hongseong-gun, Chungcheongnam-do who were at least 55 years old from November 2020 to March 2021 were included in this study. The chi-square test was performed to examine the age-specific perception of insurance-covered dental implants (p<0.05). Results: The age group that was the most interested in implants was the 70s age group, and the difference between this age group and the other age groups was statistically significant. Those in their 70's, 80's, and 90's or older paid about 600,000 won including dental implants covered by insurance, and there was a significant difference (p<0.05). Those in their 60s, 70s, and 80s estimated the highest value of implants covered by insurance as two and showed a significant difference (p<0.05). The awareness of the dental implant insurance by age showed that all age groups, except for the ≥90 years age group, considered the insurance to be mediocre mostly due to the large co-payment (p<0.05). Conclusion: There were differences by age in the awareness of dental implant insurance, co-payments, number of applications, and insurance coverage. The perceptions on dental implant insurance by age showed that all age groups except for those over 90 years and older, they considered the insurance was just mediocre the most.
