Speed sintering - Framework and reduced crowns in the anterior and posterior tooth region . - Bridge frameworks in the anterior and posterior tooth region with max. 2 pontics and up to 9 units - Crown caps in the anterior and posterior region . - Cone and telescoping crowns Super speed sintering - Framework and reduced crowns with a maximum wall-thickness of 2 mm . ## Device Story inCoris ZI consists of zirconia ceramic (ZrO2) blocks used for custom dental restorations. Blocks are mounted to metal carriers and processed via Sirona CAD/CAM grinding machines. Following grinding, restorations undergo sintering (classic, speed, or super speed) to achieve final material properties. Used in dental clinics/labs by trained professionals. Output is a custom-fit dental restoration (crowns, bridges, caps). Benefits include biocompatible, high-strength ceramic restorations tailored to patient anatomy. ## Clinical Evidence No clinical data. Bench testing performed, including sintering tests, mechanical property evaluation, crack damage inspection, restoration fit, color suitability, and usability testing. ## Technological Characteristics Material: Yttria-stabilized zirconia ceramics (ZrO2). Standards: ISO 6872:2008, ISO 13356:2008, ISO 10993-1:2009. Physical properties: Density ≥ 6.05 g/cm3, Bending strength > 1100 MPa. Form factor: Block with metal carrier for CAD/CAM spindle mounting. Processing: CAD/CAM grinding followed by sintering. ## 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 - inCoris ZI ([K062509](/device/K062509.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Sponsor Sirona Dental Systems GmbH Fabrikstrasse 31. D-64625 Bensheim Germany Contact Person: Fritz Kolle Telephone: +49 6251 16 3294 Date Prepared: March 05, 2013 #### Device Name 2. Proprietary Name: inCoris ZI Common/Usual Name: Powder, Porcelain Classification Name: Porcelain powder for clinical use #### 3. Predicate Devices inCoris ZI (K062509) #### Intended Use 4. Classic sintering - · Framework and reduced crowns in the anterior and posterior tooth region - . Bridge frameworks in the anterior and posterior tooth region with max. 2 pontics - . Crown caps in the anterior and posterior region - Cone and telescoping crowns . ### Speed sintering - . Framework and reduced crowns in the anterior and posterior tooth region - · Bridge frameworks in the anterior and posterior tooth region with max. 2 pontics and up to 9 . units - · Crown caps in the anterior and posterior region - · Cone and telescoping crowns Sirona Dental Systems 510(k) inCoris ZI Page 1 APPENDIX F {1}------------------------------------------------ Super speed sintering - Framework and reduced crowns with a maximum wall-thickness of 2 mm #### న. Device Description and Function The inCoris ZI are blocks of various sizes from which custom made dental restorations are grinded using Sirona CAD/CAM system. inCoris ZI ceramics constitute blocks comprised of zirconia ceramics (ZrO2). The blocks are initially manufactured in a partially sintered state; then, they are o individually processed to specification, and finally, densely sintered. One end plane of a block is mounted to a metal carrier that is inserted in the spindle's clamping chuck of the grinding machine. The blocks are available in different colors. #### 6. Scientific Concept The underlying scientific concept is - . Processing dental restorations by Sirona Dental CAD/CAM System - . Restorations are grinded from an inCoris ZI block by a Sirona CAM machine - . Different sintering time to gain appropriate material properties ### 7. Physical and Performance Characteristics ### 7.1. Design The design of the inCoris ZI is described in section 5, Device Description and Function. ### 7.2. Material Used inCoris ZI ceramics constitute blocks comprised of zirconia ceramics (ZrO2). One end plane of a block is mounted to a metal carrier that is inserted in the spindle's clamping chuck of the grinding machine. The material is biocompatible according to ISO 10993-1: 2009, "Biological evaluation of medical devices -- Part 1: Evaluation and testing within a risk management process". ### 7.3. Physical Properties Final technical data of densely sintered inCoris ZI. | Density: | $\geq$ 6.05 g cm-3 | |-------------------------------------------------|--------------------| | Thermal expansion

Summary of the technological characteristics Both, Proposed and Predicate Sirona inCoris ZI are made of zirconia ceramics(ZrO2) and block shaped. Both devices meet ISO 6872: 2008, "Dentistry -- Ceramic materials" and ISO 13356: 2008, "Implants for surgery, Ceramic materials based on yttria-stabilized tetragonal zirconia (Y-TZP)". Physical and chemical properties are similar. ### Nonclinical Testing 9. Sirona performed a series of tests to assess whether the device is appropriate for the indications for use. Sintering tests coupled with bench mechanical testing highlight that the mechanical properties are appropriate. Furthermore, crack damage inspection, restoration fit, color suitability, and overall usability tests were conducted. #### 10. Clinical Testing Clinical tests have not been performed. ### 11. Conclusion Based on the comparison of intended use, indications, contra-indications, material properties and processing/fabrication, Sirona Dental Systems believes that the Proposed and Predicate (K062509) Sirona inCoris ZI blocks are substantially equivalent.
