Indications for Use
BruxZir® NOW SRC is a pre-manufactured prosthetic component directly connected to an endosseous implant and it is intended for use in prosthetic rehabilitation. BruxZir® NOW SRC consists of two major parts. Specifically, the precemented titanium abutment and zirconia superstructure components make up a two-piece abutment. All digitally designed CAD/CAM customizations for BruxZir® NOW SRC are only intended to be designed and manufactured according to digital dentistry workflow, which incorporates of the digital dentistry workflow including scan files from Intra-Oral Scanners, CAD software, milling machine and associated tooling and accessories.
Device Story
BruxZir® NOW SRC is a two-piece hybrid abutment crown consisting of a pre-cemented titanium base (Ti-base) and a fully sintered yttria-stabilized zirconia superstructure. It is used in conjunction with endosseous dental implants to restore chewing function. The device is designed via a digital dentistry workflow using intra-oral scanner data, CAD software, and an in-office milling unit (fastmill.io™). The clinician or dental laboratory designs the final abutment shape, including anatomic features, which is then milled and mounted onto the implant using a screw. The device is intended for prescription use in a dental clinic setting. The output is a patient-specific prosthetic restoration that replaces missing tooth structure, benefiting the patient by restoring chewing function and aesthetics. The device is provided non-sterile and requires steam sterilization by the end-user prior to clinical use.
Clinical Evidence
No clinical data included. Substantial equivalence is supported by non-clinical bench testing, including static load and fatigue testing per ISO 14801:2016, biocompatibility evaluation per ISO 10993-1, and steam sterilization validation per ISO 17665-1:2006.
