Intended Use

Implant Direct Custom Bars are patient specific devices indicated for attachment to dental implants in the treatment of partially or fully edentulous jaws for the purpose of restoring chewing function.

Device Story

Custom Bars are patient-specific, CAD/CAM-milled prosthetic frameworks designed to attach to dental implants or abutments. Input data (patient anatomy/implant location) is obtained conventionally or digitally. CAD software designs the bar based on clinical parameters; clinician approves design before manufacturing. CAM system mills the bar from wrought titanium alloy (ASTM F136). Device is shipped non-sterile to the clinician for final restoration finishing. Used in dental clinics to support dentures or fixed-detachable frameworks. Provides structural support for prosthetic teeth, restoring chewing function for edentulous patients.

Clinical Evidence

No clinical data provided. Substantial equivalence supported by bench testing, including mechanical fatigue testing (ISO 14801), bending strength testing (ASTM F382), biocompatibility (ISO 10993-1/5), and steam sterilization validation (ISO 17665-1/2).

Technological Characteristics

Material: Wrought Titanium Alloy (ASTM F136). Design: CAD/CAM-milled, patient-specific, one-piece framework with fixation screws. Dimensions: 4-10 cylinders, 0-17mm span, 0-10mm distal extension, 0-7mm cylinder height. Sterilization: Non-sterile, validated for steam sterilization (Gravity Displacement/Pre-vacuum).

Indications for Use

Indicated for partially or fully edentulous patients requiring dental implant-supported prosthetic restorations. Compatible with specific Implant Direct InterActive and SwishActive implant systems and straight multi-unit abutments.

Regulatory Classification

#### 4. DEVICE DESCRIPTION

Implant Direct Custom Bars are computer-aided design/computer-aided manufacturing, individually designed prosthetic devices for partially or fully edentulous restorations. The bars and fixation screws are made from Wrought Titanium Alloy conforming to an FDA recognized consensus standard ASTM F136. The Custom Bars consist of two

{4}------------------------------------------------

device types: fixed-detachable frameworks and overdenture bars. The bar systems consists of the bars as well as fixation screws to facilitate the attachment to the dental implants.

Implant Direct Custom Bars are attached directly to an implant to provide support for the fabricated denture. The implant specific interfaces on the Custom Bars are designed and manufactured with precise mating features in order to the mating surfaces of the implants or abutments.

The Implant Direct Custom Bars are designed and produced at Implant Direct under the direction of clinical professionals. The patient requirements and implant locations are obtained conventionally or digitally and a bar is designed, using CAD software, according to established customization parameters. Once the design is finished, the bar design is sent to the clinician for approval before manufacture. After bar design approval is received, the bar design is milled using a precise CAM system, inspected, cleaned, packaged non-sterile, and shipped to the customer where it is finished into the final restoration.

The proposed device and predicates have the same general design, similar production methods, same size cylinder wall, allow for the same final restoration types, and have the same sterilization methods.

The differences between the proposed devices and the predicate devices have also been evaluated. The proposed bars have smaller allowable span, equivalent or smaller distal extension, smaller cylinder height, different bar profiles, and larger fixation screws. Performance testing has shown to support substantial equivalence to the reference predicate. Though the material used in subject device is different from the primary predicate, it is equivalent to that of the reference predicate. The differences in Custom Bar parameters and materials, used to construct the proposed device, do not affect substantial equivalence.

## 8. PERFORMANCE DATA

{9}------------------------------------------------

Non-clinical testing was performed on the proposed device. Testing include mechanical strength, biocompatibility, and cleaning and steam sterilization validation. Results indicated that the subject device is equivalent to the predicate device.

- Mechanical testing
- o Fatigue testing was performed on worst-case configuration per ISO 14801. Results indicated that the bar interface successfully completed endurance testing and was equivalent to the predicate device.
- Bending strength testing was performed on worst-case bar according to a o modified version of ASTM F382. Results indicated that the subject device is equivalent to the predicate device.
- Biocompatibility testing was performed per ISO 10993-1 and ISO 10993-5. ● Cytotoxicity testing and comprehensive biocompatibility evaluation was conducted. Results indicate that the device met all biocompatibility requirements for its intended use. The material of subject device conforms to FDA recognized consensus standard ASTM F136 and is equivalent to the reference predicate.
- . The subject devices are provided non-sterile and to be end user sterilized. Steam sterilization validation was performed on the worst case sample per ISO 17665-1 and ISO 17665-2. Results indicated the acceptance criteria was met and the devices can be sterilized per Gravity Displacement and Pre-vacuum cycle parameters.

## 9. CLINICAL PERFORMANCE DATA

Clinical Performance testing was not performed. Clinical data is not required to support substantial equivalence.

## 10. CONCLUSION

Implant Direct Custom Bars are substantially equivalent to the legally marketed device(s) from Dentsply International ISUS Implant Suprastructures (K122424). The intended use, design features, and materials of the subject devices are equivalent to those of the predicate devices. The fundamental scientific technology of the modified devices has not changed relative to the predicates devices. The application is adequately supported by the substantial equivalence information, materials information, and analysis data provided within this premarket notification. The subject device is substantially equivalent to the declared predicates.
