Applicant Address: 2144 Michelson Drive, Irvine, CA 92612, USA Applicant Contact Telephone: 949-863-5479 Applicant Contact: So Hyun Park, Regulatory Affairs Manager, MS Applicant Contact Email: so.park(@glidewelldental.com ### DEVICE NAME (21 CFR 807.92(a)(2)) Device Trade Name: BruxZir® Esthetic Common Name: Zirconia milling block or dental CAD/CAM block Classification Name: Porcelain powder for clinical use Regulation Number: 872.6660 Regulatory Class: Class II Product Code: EIH ## LEGALLY MARKETED PREDICATE DEVICE (21 CFR 807.92(a)(3)) Predicate 510(k) #: K231425 Predicate Trade Name: BruxZir® Esthetic Product Code: EIH ## DEVICE DESCRIPTION SUMMARY (21 CFR 807.92(a)(4)) BruxZir® Esthetic blanks are zirconia milling blanks used for the production of highly esthetic zirconia dental restorations. The high esthetics and high strength of BruxZir® Esthetic restorations make them viable for use in all regions of the mouth. The manufactured dental restorations are made utilizing a CAD/CAM system for design and manufacture. The designed and manufactured dental restorations are then sintered at a high temperature. BruxZir® Esthetic blanks are available in white, bleach, and pre-shaded varieties that can be easily adjusted to match the final shade. ### INTENDED USE/INDICATIONS FOR USE (21 CFR 807.92(a)(5)) The device is indicated for use by dental technicians in the construction of custom made all ceramic restorations for anterior and posterior location. {5}------------------------------------------------ Image /page/5/Picture/0 description: The image shows the logo for Prismatik Dentalcraft, Inc. The logo consists of a triangle on the left side that is divided into sections of different colors, including pink, red, yellow, green, blue, and purple. To the right of the triangle is the company name, "PRISMATIK DENTALCRAFT, INC.", in a sans-serif font. ## INDICATIONS FOR USE COMPARISON (21 CFR 807.92(a)(5)) The subject device, BruxZir® Esthetic, has the same indications for use as the predicate device, BruxZir® Esthetic (K213425). Both devices are indicated for use by dental technicians in the construction of custom made all ceramic restorations for anterior and posterior location. ### TECHNOLOGICAL COMPARISON (21 CFR 807.92(a)(6)) The subject device, BruxZir® Esthetic, is substantially equivalent in technical characteristics to the predicate device, BruxZir® Esthetic (K213425) in terms of overall design principles, material, and performance. The subject device, BruxZir® Esthetic, is similar in terms of overall design to the predicate device, BruxZir® Esthetic (K213425). The subject device, BruxZir® Esthetic, is offered in a milling blank and GL Single Unit design to be used for milling single-unit restorations. The predicate device, BruxZir® Esthetic (K213425), is offered in the same designs with the addition of the GL Bridge Block, which is designed to be used for milling bridges (restorations of three or more units). The fundamental principle of operation of the subject device, BruxZir® Esthetic, and the predicate device, BruxZir® Esthetic (K213425), is the same. The manufactured dental restorations are made utilizing a CAD/CAM system for design and manufacture. The designed and manufactured dental restorations are then sintered at a high temperature. Although no color needs to be added additionally, pre-coloring before sintering and/or basic staining and glazing techniques may be used after sintering to achieve the desired shade. Also, the change in the manufacturing process from the press process to the colloidal process (slip casting) does not affect the mechanical properties of the final finished device. The subject device, BruxZir® Esthetic, is similar in terms of material composition to the predicate device, BruxZir® Esthetic (K213425). The main ceramic component is composed of yttriastabilized zirconia with varying trace amount of colorants. As the generic type of material has not changed, it does not alter the performance specifications of the subject device. The slight differences in overall chemical composition do not affect the biocompatibility and performance characteristics. The technological comparison table below outlines and provides the similarities between the subject device, BruxZir® Esthetic, and the predicate device, BruxZir® Esthetic (K213425). Both the subject device and the predicate device have similar physical/mechanical and biocompatibility properties that met the requirements of ISO 6875:2015/Amd 1:2018 (Type II, Class 5) and ISO 10993. Any differences between the subject device and the predicate device do not raise any new concerns of safety and effectiveness. {6}------------------------------------------------ Image /page/6/Picture/0 description: The image shows the logo for Prismatik Dentalcraft, Inc.
