Indications for Use
The NobelPerfect Abutments are pre-manufactured prosthetic components directly connected to the endosseous dental implant and are intended for use as an aid in prosthetic rehabilitation.
Device Story
NobelPerfect Abutments are pre-manufactured prosthetic components (healing and definitive) designed for use with the Replace Scalloped Margin Implant System (NobelPerfect Implants). These abutments serve as an interface between the endosseous dental implant and the final dental restoration. They are available in narrow, regular, and wide platforms. The definitive abutments feature a base extension intended to improve stability and are available in a 12.0 mm height. The devices are used by dental clinicians during prosthetic rehabilitation procedures. The abutments are manufactured from titanium vanadium alloy. The device is provided sterile and is intended to facilitate the restoration of chewing function in patients.
Clinical Evidence
Bench testing only. No clinical data provided. Fatigue testing was performed in accordance with ISO 14801. Biocompatibility, sterilization (Gamma radiation per ANSI/AAMI/ISO 11137), packaging, and shelf-life (3 years) were supported by leveraging data from predicate and reference devices due to identical materials, manufacturing, and intended use.
Technological Characteristics
Materials: Titanium vanadium alloy (ASTM F1472, ASTM F136). Design: Single-piece abutments with scalloped sides and base extension. Platforms: Narrow, Regular, Wide. Sterilization: Gamma radiation. Connectivity: Mechanical interface to endosseous dental implant. No software or electronic components.
Indications for Use
Indicated for use as prosthetic components connected to endosseous dental implants to aid in prosthetic rehabilitation in patients requiring dental restoration.

Analysis of Differences Between Subject Device and Predicate
The NobelPerfect Abutments are replacement abutments for the existing NobelPerfect implant system. Both the definitive and healing abutments have been redesigned to include some improvements. The definitive abutments differ from the predicate abutments in that they have a base extension that extends into the implant that is intended to improve abutments stability. The abutments are also longer than the predicate to facilitate more restorative options. The healing abutments are made of titanium alloy instead of Delrin plastic as the predicate is. The RP and WP platform healing abutments have a slight scallop taper whereas the predicate is straight.
{6}------------------------------------------------
Summary:
The design differences between the subject and predicate were evaluated. Differences in technology were evaluated through performance testing.
## VII. PERFORMANCE DATA
Summary of Non-Clinical Testing:
Since the subject device does not represent a new worst case, data from the reference predicate device TREFOIL System (K170135) was leveraged in the following aspects of the 510(k).
- -Sterile Device Information
- o The sterilization method for the subject device is the same as the predicate. The sterilization method is Gamma radiation and has been validated in accordance with ANSI/AAMI/ISO 11137. Therefore, no additional testing was required.
- -Device Packaging
- o The packaging for the subject device is the same as the predicate. This is a thermoform tray with peel top lid. Therefore, no additional testing was required.
- -Shelf Life
- The packaging for the subject device is the same as the predicate and o is labeled with a 3 year expiration date. Real time aging was used to determine the expiration dating. Therefore, no additional testing was required.
- -Biocompatibility
- The subject device is manufactured from the same material as the o predicate, uses the same manufacturing method as the predicate, has the same intended use, and the same patient contact type and duration. Therefore, no additional testing was required.
The fatigue limit of the NobelPerfect Abutment was determined using ISO 14801.
### VIII. CONCLUSIONS
The NobelPerfect Abutments were evaluated for substantial equivalence using standard testing. In cases where the NobelPerfect Abutments could be shown to not represent a worst-case with respect to the predicates, data from these predicate devices was leveraged to support the subject device. Based on technological characteristics and non-clinical test data included in this submission, the NobelPerfect Abutments have been shown to be substantially equivalent to the Replace Scalloped Margin Implant System (K021584).
