This advantage is shown in stable shades performance after more than 10 years of aging. Godzillaking dental zirconia can keep it's shade in mouth over 10 years. The advantage have been proved by our research and development group. The following is the report from Godzillaking research and development group. ↓↓↓
Core Conclusion of the Report
Godzillaking zirconia block by artificial accelerated aging test, verify its:
- 12-16 years of artificial aging simulation experiment results: all shade difference values Δ E < 1.2, far below the 3.3 (clinically acceptable shade difference)
Shade stability test (shade difference analysis after aging)
- Purpose of the test:
This report was designed to test the shade performance of Godzillaking zirconia blocks after over 10 years of aging.
- Method:
Godzillaking R&D team made milling and sintering of 4 types of zirconia block products (4D-X zirconia block, 4D Pro zirconia block, Preshade zirconia block, White zirconia block) according to the instructions. The experimental group are named as 4D-X, 4D Pro, Preshade, and White respectively. The zirconia samples are processed in a steam autoclave. 4 hours of processing in 134℃ high pressure steam and 2 bar pressure can simulate 12-16 years of oral aging process. CIE L*, a*, b* values before and after aging were measured by computer colorimeter and other related instruments, and the shade difference value (ΔE) was calculated.
- Godzillaking zirconia disc shades difference experiment results：
A shade variation of ∆E≤3.3 is clinically acceptable. After a 4-hour manual aging test, all ∆E models are less than 3.3. There was no significant shade change in the 4 types of zirconia blocks after aging.
∆E of each group after 4h of artificial aging ↑
