Inputs consist of clinical design parameters provided by the clinician for specific prosthetic cases and implant interfaces. The device transforms these inputs into a physical titanium alloy abutment featuring anti-rotation geometry compatible with specific implant systems (Nobel Biocare, 3i). Used in dental clinics by clinicians to support single or multiple tooth prostheses. The output is a custom-milled abutment that connects the dental implant to the final restoration. Benefits include improved prosthetic fit and functional support for edentulous patients. ## Clinical Evidence Bench testing only. Evidence includes engineering analysis, dimensional analysis, static and dynamic compression-bending testing per ISO 14801, and sterilization validation per ISO 17665. No clinical data presented. ## Technological Characteristics Material: Titanium alloy. Fabrication: CAD/CAM scanning and milling. Dimensions: 3.5, 4.1, 4.3, 5.0, 5.1, 6.0 mm diameters; straight or angled up to 30°. Features: Anti-rotation geometry. Sterilization: ISO 17665 compliant. ## Regulatory Identification An endosseous dental implant abutment is a premanufactured prosthetic component directly connected to the endosseous dental implant and is intended for use as an aid in prosthetic rehabilitation. ## Special Controls *Classification.* Class II (special controls). The guidance document entitled “Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Implant Abutments” will serve as the special control. (See § 872.1(e) for the availability of this guidance document.) ## Predicate Devices - TDS Abutment for Friadent Xive ([K103339](/device/K103339.md)) - TDS Titanium Abutment for Nobel Biocare Bränemark ([K091392](/device/K091392.md)) - TDS Abutment for Nobel Biocare Replace ([K091026](/device/K091026.md)) - TDS Abutment ([K081460](/device/K081460.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Milling of NDX Custom Abutments includes anti-rotation features compatible with specific implant systems. Each abutment is made from titanium alloy. It is created according to the specific design parameters designated by the clinician. All components and parameters of the system remain identical to those cleared for the TDS Abutment System predicates. Abutments are available in diameters of 3.5, 4.1, 4.3, 5.0, 5.1, and 6.0 mm, and can be fabricated straight or with an angle up to 30°. {2}------------------------------------------------ ## EQUIVALENCE TO MARKETED DEVICE National Dentex submits the following information in this Premarket Notification to demonstrate that, for the purposes of FDA's regulation of medical devices, NDX Custom Abutments is substantially equivalent in indications and design principles to the following predicate devices, all manufactured by Pou Yu Biotechnology Co., Ltd.: TDS Abutment for Friadent Xive - K103339. TDS Titanium Abutment for Nobel Biocare Bränemark - K091392, TDS Abutment for Nobel Biocare Replace - K091026, and TDS Abutment - K081460 The purpose of this submission is to give National Dentex Corporation the ability to utilize the currently cleared TDS CAD/CAM Abutment System for dental implant abutment fabrication. All component designs and parameters of the system remain identical to those previously cleared for the TDS CAD/CAM Abutment System. Mechanical testing was conducted on worst-case constructs of NDX titanium abutments according to ISO 14801 Dentistry - Implants - Dynamic fatigue test for endosseous dental implants and results showed adequate strength for their intended use. Extensive compatibility testing was performed in support of NDX Abutments. Multiple parameters of the NDX abutments and corresponding implants with designated screws were evaluated to determine appropriate fit. Non-clinical testing data submitted, referenced, or relied upon to demonstrate substantial equivalence included: engineering analysis, dimensional analysis, static and dynamic compression-bending testing according to ISO 14801, and sterilization validation according to ISO 17665. The data included in this submission demonstrates substantial equivalence to the predicate devices listed above. Overall, NDX Custom Abutments have the following similarities to the predicate devices: - have the same intended use, . - . use the same operating principle, - . incorporate the same design, - . incorporate the same materials, and - . have similar packaging and are sterilized using the same materials and processes. {3}------------------------------------------------ #### DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/3/Picture/1 description: The image shows the logo for the U.S. Department of Health and Human Services.
