Device Story

ISUS Implant Suprastructures are customized metallic dental restorative devices (bars, bridges, hybrids) designed to restore chewing function in edentulous patients. Dental professionals provide patient dentition models; DENTSPLY converts these to digital representations using CAD/CAM technology to manufacture patient-specific suprastructures. Devices are screw-retained to dental implants or abutments. Bars support removable prostheses; bridges allow veneering for fixed prostheses; hybrids serve as substructures for bonded dentures. Used in dental clinics; operated by dental professionals. Output is a custom-fit metallic structure that integrates with existing implant systems to provide a stable foundation for dental restorations, benefiting patients by restoring oral function.

Clinical Evidence

No clinical data. Bench testing only. Dynamic fatigue testing performed per ISO 14801:2007 in simulated implant-supported constructs. Material properties verified per ISO 22674:2006 and ISO 9693:1999 for chemical composition, strength, and corrosion resistance.

Technological Characteristics

Customized metallic restorative devices; unalloyed CP titanium or cobalt-chromium alloy. CAD/CAM manufacturing. Screw-retained connection. Standards: ISO 14801 (fatigue), ISO 22674 (materials), ISO 9693 (metal-ceramic systems), ISO 17665-1/2 (sterilization).

Indications for Use

Indicated for partially or totally edentulous patients requiring restoration of chewing function via screw-retained dental prostheses attached to a minimum of two dental implants or abutments.

Regulatory Classification

#### 5.4 Description of Device:

The ISUS Implant Suprastructures are metallic dental restorative devices which are intended for attachment by screw retention to dental implants to aid in the treatment of partially and totally edentulous patients for the purpose of restoring chewing function. The ISUS system consists of the Suprastructure devices themselves as well as retention screw accessories which facilitate their attachment to the dental implants.

The design of the ISUS Implant Suprastructures is derived from models of patient dentition which are produced by the dental professional using standard dental techniques. The dental models are converted to digital representations by DENTSPLY to facilitate DENTSPLY's Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) of the customized, patient-specific ISUS Implant Suprastructure.

{1}------------------------------------------------

The ISUS Implant Suprastructures consist of three (3) device types:

- Bars Intended to act as a supporting structure to facilitate attachment of . removable dental prostheses.
4122424

- . Bridges - Intended for direct veneering using dental ceramics or resin composites resulting in a fixed, screw-retained prosthesis.
- Hybrids Intended as a metallic substructure to which finished dentures . are bonded to form a fixed prosthesis.

The ISUS Implant Suprastructures are manufactured in versions composed of titanium and cobalt-chromium alloy and feature customized designs derived from individual patient dental impressions.

#### 5.5 Indications for Use:

#### ર .6 Description of Safety and Substantial Equivalence:

# . Technological Characteristics.

The ISUS Implant Suprastructures are customized metallic restorative devices. The CAD design of the devices is derived by DENTSPLY from individual patient dental impressions produced by dental professionals. The fabrication of the devices is performed by DENTSPLY using automated CAM manufacturing methods. The ISUS Implant Suprastructures feature the following technical characteristics:

- Screw retained with connection to dental implants or abutments. .
- Unalloyed, commercially-pure (CP) titanium or cobalt-chromium . alloy construction.
- . Fabricated from homogenous, single-block raw material (CP titanium or cobalt-chromium alloy).

# Non-Clinical Performance Data.

Dynamic fatigue testing was conducted to evaluate the mechanical integrity of the ISUS device constructs. Representative worst-case test samples were constructed and subjected to cyclic loading in a simulated, implant-supported construct. Dynamic testing was conducted according to the method described in ISO 14801:2007 (Dentistry - Implants - Dynamic fatigue test for endosseous dental implants). The results of the dynamic testing were compared to the results of equivalent testing which was conducted on legally marketed predicate dental abutments as well as to published in vitro data regarding maximum bite and chewing forces in edentulous patients. The results of the dynamic fatigue testing showed that the lowest fatigue strength of the ISUS Implant Suprastructures supports substantial equivalence.

Additionally, the materials which comprise the the ISUS Implant Suprastructures have been tested according to ISO 22674:2006 (Dentistry -- Metallic materials for fixed and removable restorations and appliances) and ISO 9693:1999 (Metal- ceramic dental restorative systems) to verify that the requirements for: chemical composition. proof strength, elongation after fracture, corrosion resistance, linear thermal expansion, and metal-ceramic bond strength are met. The results of the testing showed that the materials of which the ISUS Implant Suprastructures are composed conform to the requirements for these characteristics as specified in the relevant standards.

Recommended sterilization parameters which have been validated according to ISO 17665-1: 2006 (Sterilization of health care products -- Moist heat -- Part 1: Requirements for the development, validation and routine control of a sterilization process for medical devices) and ISO 17665-2: 2009 (Sterilization of health care products - Moist heat - Part 2: Guidance on the application of ISO 17665-1) are provided in accordance with ANSI/AAMI ST79:2010 (Comprehensive guide to steam sterilization and sterility assurance in health care facilities).

### Clinical Performance Data.

Not applicable. No human clinical study was performed to support substantial equivalence.

# Conclusion as to Substantial Equivalence

The proposed ISUS. Implant Suprastructures are substantially equivalent to the predicate Biomet 3i CAM StrucSURE Overdenture Bar (K101582) and Procera®. Implant Bridge Overdenture (K090069). The proposed devices have the same intended use and indications for use, are composed of the same or similar materials, and are characterized by the same fundamental product technology as the predicate devices. Testing has been conducted on the materials which compose the ISUS Implant Suprastructures and the results show conformity to the relevant standards for the properties which were studied. Additionally, in vitro test data has been to confirm the mechanical integrity of of the included ISUS Implant Suprastructures through dynamic fatigue testing in representative worst case constructs. The fatigue strength results for the ISUS Implant Suprastructures support substantial equivalence.
