Rosetta SP is a lithium disilicate glass-ceramic ingot that was first developed and commercialized in Korea and the second in the world. 

With its high quality, stable domestic production, and competitive pricing, the material has steadily gained attention among users.

In this issue, we conducted interviews with Won-pil Jang, Chief Dental Technician at Lee Hee-kyung Dental Art Laboratory, 
and Gun-hyo Kim, Chief Dental Technician at Seoul Goldplant Dental Clinic, both experienced domestic users of Rosetta SP.

Expanding Market Share Through Localization of Lithium Disilicate

Founded in 2008, HASS Co., Ltd. has steadily advanced in the field of esthetic dental restorative materials—an area traditionally dominated by European and American manufacturers. 
The company has consistently focused on delivering high-quality products and advanced technologies that meet the expectations of dental technicians.

In particular, HASS has strengthened its market position by successfully localizing lithium disilicate glass-ceramic materials, which had previously relied heavily on imported products.

Rosetta SP has gained steady popularity in regions such as Latin America and the Middle East, where demand for pressing ingots is high and price sensitivity is strong. 
The material has been widely used for esthetic restorations such as laminate veneers, which continue to see increasing demand in these markets.

Quality That Earns the Trust of Users

For Won-pil Jang, the primary criteria when selecting press ingots for anterior laminate veneers or posterior inlays are shade reproduction and strength.

After using Rosetta SP, Jang commented:

“Compared with other products, Rosetta SP offers slightly higher strength and a broader range of shades for accurate color reproduction, which makes it well suited for my clinical work.”

He also added:

“It demonstrates excellent morphology reproduction and marginal adaptation. After polishing, the surface becomes very smooth, 
which is beneficial for the periodontal environment. For these reasons, it is a material I can confidently use in clinical practice.”

Consistent Pressing Results and Excellent Marginal Detail

Another user, Gun-hyo Kim, highlighted the consistent and high-quality results during the pressing process as a key advantage of Rosetta SP.

Kim explained:

“In my case, I use an ingot press machine rather than a dedicated press furnace. Even with this physical pressing method, 
the material shows excellent reproduction of fine marginal details. 
This makes it reliable for restorations such as inlays and laminate veneers, where thin and delicate structures must be accurately reproduced.”
 

He also noted that when used together with Amber Vest, HASS’s investment material:

“A consistent and appropriately thick reaction layer forms during pressing, and it is easy to remove. 
As a result, restorations often achieve excellent fit with minimal adjustment during try-in.”

Kim added that LT shades provide effective masking even in typical discolored tooth laminate veneer cases 
when a thickness of approximately 1 mm is secured, making the restoration process more predictable and efficient.

Trusted by Users Worldwide

With its excellent shade reproduction, stable strength, and precise marginal detail reproduction, Rosetta SP has already gained strong trust among domestic users.

Internationally, the product was exported to approximately 50 countries as of 2022,
 and the Rosetta brand has built a loyal customer base worldwide, receiving continuous feedback and reviews from users.

In Korea, HASS ensures stable manufacturing and supply, while maintaining strong price competitiveness based on high product quality.

The wide range of available shades also enables highly esthetic restorations, making Rosetta SP a preferred material among dental technicians seeking to create high-quality prosthetic restorations.
