Benefits: provides esthetic, durable all-ceramic restorations for patients requiring tooth replacement or repair. ## Clinical Evidence No clinical data. Bench testing performed in accordance with ISO 6872:2008 (Dentistry - Ceramic materials). Biocompatibility assessment conducted per ISO 10993-1:2009. ## Technological Characteristics Silica and lithium-based glass ceramic containing SiO2, Li2O, and coloring oxides. Form factor: heat-pressed ingot. Fabrication: heat-pressed technology. Standards: ISO 6872:2008, ISO 10993-1:2009. ## Regulatory Identification Porcelain powder for clinical use is a device consisting of a mixture of kaolin, felspar, quartz, or other substances intended for use in the production of artificial teeth in fixed or removable dentures, of jacket crowns, facings, and veneers. The device is used in prosthetic dentistry by heating the powder mixture to a high temperature in an oven to produce a hard prosthesis with a glass-like finish. ## Predicate Devices - IPS E.MAX PRESS / IPS E.MAX PRESS MULTI ([K120134](/device/K120134.md)) ## Reference Devices - IPS E.MAX CAD / IPS E.MAX ZIRCAD ([K051705](/device/K051705.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Substantial equivalence The applicant device and primary predicate device both are silica lithium based ceramics with formulations of ceramic oxides used in combination to create a range of shades and translucencies; and that the form of the device is an ingot that is used in heat-pressed technology to fabricate all ceramic restorations. The difference is that the chemical formulation is not identical; however bench testing for both devices was conducted in accordance with ISO 6872:2008 (Dentistry - Ceramic Materials) confirming that the physical properties of the applicant device are comparable to the primary predicate for the same intended use. The applicant device is similar to the reference device in that both are also silica lithium based ceramics and includes other glass and ceramic oxides in the device formulation. While the technology used to fabricate the all ceramic restoration differs in that the applicant device uses heatpressed technology and the reference device uses CAD/CAM technology; the differences in chemical composition and technology used to fabricate the all ceramic restorations do not alter the raise concerns about the intended use of the applicant device. Wording of indications for use statement of the applicant device for fabrication of crown or splinted crown on top of an implant abutment has the same intended meaning as the words for creation of crown, and splinted crown. The indications for use are equivalent for Initial LiSi Press and the primary predicate device. ## 10. Conclusion Based on device formulation and non clinical performance testing, including bench testing and biocompatibility assessment, Initial LiSi Press is substantially equivalent to the predicate devices.
