Intended Use

The Healing Abutment System is indicated for temporary connection to a dental implant to support healing of the surrounding soft tissue.

Device Story

Healing Abutment System consists of titanium healing abutments and scan healing abutments; used for temporary connection to dental implants to support soft tissue healing prior to prosthetic placement. Scan healing abutments incorporate specific design features (grooves/markers) to facilitate intraoral digital scanning for prosthetic fabrication. Devices are used in dental clinics by clinicians. Input is the physical interface with the dental implant; output is the support of soft tissue architecture and, for scan versions, a geometry identifiable by intraoral scanners. Benefits include optimized soft tissue healing and simplified digital impression workflows. Devices are non-load-bearing.

Clinical Evidence

No clinical data submitted. Substantial equivalence is based on non-clinical performance testing, including biological risk assessment per ISO 10993-1, sterilization validation per ISO 11137, and MRI compatibility assessment based on scientific rationale and literature.

Technological Characteristics

Materials: Titanium Grade 4 (ASTM F67) and Ti-6Al-4V (ASTM F136). Sterilization: Gamma irradiation (SAL 10^-6). Design: Various diameters and heights/lengths for TS, SS, and US implant connections. Scan healing abutments include grooves/markers for intraoral scanning. Non-load-bearing.

Indications for Use

Indicated for temporary connection to a dental implant to support healing of the surrounding soft tissue in patients requiring dental implant restoration.

Regulatory Classification

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.

You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Indications for Use The Healing Abutment System is indicated for temporary connection to a dental implant to support healing of the surrounding soft tissue. ## 7. Summary of Non-clinical Performance Testing Non-clinical testing data are submitted to demonstrate substantial equivalence. ### Biocompatibility Evaluation The biocompatibility of the subject devices was evaluated in accordance with ISO 10993-1:2018, “Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process” and the FDA guidance, “Use of International Standard ISO 10993-1, Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process”. The following evaluations were performed: - Biological Risk Assessment per ISO 10993-1 The subject devices are manufactured from commercially pure titanium and titanium alloy with a long history of safe clinical use and have identical materials and manufacturing processes as the predicate devices. Based on risk assessment and chemical characterization, no new issues regarding biocompatibility were identified, and no additional biocompatibility testing was required. ### Sterilization Validation and Shelf-life The subject devices are sterilized by gamma irradiation. Sterilization validation for the predicate devices was performed in accordance with ISO 11137-1, ISO 11137-2, and ISO 11137-3, establishing a Sterility Assurance Level (SAL) of $10^{-6}$ using the VDmax 25 method. The subject devices are manufactured using the same materials, manufacturing processes, packaging system, and sterilization modality as the predicate devices, and do not represent a new worst-case condition. Therefore, the predicate sterilization validation is considered applicable, and additional validation was not required. The Healing Abutment System is manufactured from medical-grade titanium and titanium alloy, which are well known to be chemically stable and not susceptible to material degradation over time. Accordingly, material aging is not expected to impact on the sterility or performance of the device throughout the labeled shelf life. ### MR Compatibility Non-clinical worst-case MRI review was performed to evaluate the Subject device components in the MRI environment using scientific rationale and published literature (e.g., Woods, Terry O., Jana G. Delfino, and Sunder Rajan, "Assessment of Magnetically Induced Displacement Force and Torque on Metal Alloys Used in Medical Devices." Journal of Testing and Evaluation 49.2 (2019): 783-795), based on the entire system including all variations (all compatible implant bodies, abutments, and fixation screws) and material composition. Rationale addressed parameters per the FDA guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment," including magnetically induced displacement force and torque. ## 8. Summary of Clinical Testing No clinical studies are submitted. ## 9. Conclusion The Healing Abutment System has the same intended use and similar design characteristics as the predicate and reference devices. The subject devices are manufactured using identical materials (commercially pure titanium and titanium alloy), manufacturing processes, sterilization method, and packaging system as the QS-QI-505-7 (Rev.0) - 13/13 - Letter (8.5 X 11in) {17} K251434 Page 14 / 14 predicate devices. Differences between the subject and predicate devices are limited to dimensional ranges (diameter and length), implant compatibility, packaging appearance, and additional scan-related design features (e.g., groove or scan marker). The dimensional ranges remain within those of the predicate devices, and the devices are intended for soft tissue healing only and do not perform a load-bearing function. Biological risk assessment in accordance with ISO 10993-1, as well as sterilization validation and shelf-life evaluation in accordance with ISO 11137-1, -2, and -3, confirmed that the differences do not raise new safety or effectiveness concerns. Based on the similarities in intended use, technological characteristics, materials, and the supporting test results, the subject Healing Abutment System is considered substantially equivalent to the predicate devices.
