Intended Use

The Klockner Dental Implant Abutments are intended to be placed into dental implants to provide support for prosthetic reconstructions such as crowns, bridges. The Klockner Dental Implant Abutments include protective cap, temporary abutment, angled abutments, straight abutments, cast abutments are intended to be used with the Klockner Dental Implant Systems, models: Essential EC, Essential EC 1.5.

Device Story

Prosthetic components for dental implants; includes protective caps, temporary abutments, angled/straight abutments, and cast abutments. Used by dental clinicians to support crowns and bridges. Protective caps/temporary abutments used provisionally; angled/straight abutments used for definitive screw-retained restorations; cast abutments used for cement- or screw-retained restorations via casting technique. Components connect to Klockner Essential EC/EC 1.5 implants. Clinicians select components based on anatomical needs (transmucosal height, angulation) to facilitate prosthetic fitting. Benefits include anatomical characterization of gum margin and restoration of dental function. Provided non-sterile; requires clinician-performed steam sterilization before use.

Clinical Evidence

No clinical data. Bench testing only, including fatigue testing per ISO 14801, biocompatibility evaluation per ISO 10993-1/ISO 7405, and corrosion resistance testing (ISO 10993-15, ASTM F746, ASTM G71).

Technological Characteristics

Materials: Titanium alloy (ASTM F136, ISO 5832-3), Gold alloy 6019, Co-Cr-Mo alloy (ASTM F1537, ASTM F799, ISO 5832-12). Connection: Internal octagonal cone. Sterilization: Steam (ISO 17665-1).

All materials used in the manufacture of Klockner Dental Implant Abutments (II) have been subject to biological evaluation taking account the intended use of the devices and the nature and duration of contact with the patient, according to the requirements of applicable recognized standards ISO 10993-1:2009 and ISO 7405:2008. In the case of Co-Cr cast abutments, the potential degradation of the material in biological environments has also been contemplated; corrosion resistance and galvanic corrosion assays have been carried out according to ISO 10993-15, ASTM F746 and ASTM G71, and test results confirm the high corrosion resistance of Co-Cr-Mo alloy and show an insignificant galvanic corrosion of this material with respect to unalloyed titanium (Ti c.p.) and titanium alloy (Ti-6Al-4V). The materials and manufacturing methods used for the subject device are identical to those used in the previously cleared devices, and so additional biocompatibility testing was not considered to be necessary to support the substantial equivalence of the subject device. - Sterilization . Klockner Dental Implant Abutments (II) have been subject to bioburden and sterility testing in accordance with ISO 11737-1 and ISO 11737-2, respectively. Steam sterilization validation according to ISO 17665-1 has been carried out to confirm the sterilization parameters. - . Bench testing Fatigue testing, conducted according to ISO 14801 and the Guidance for Industry and FDA Staff: Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments, has been performed considering worst-case conditions. Results obtained show that devices performance is acceptable as per their intended use. #### Summary Discussion of Clinical Data: No clinical data are included in this submission. #### Conclusions: We consider that the intended use, the operation principle and the technological characteristics of Klockner Dental Implant Abutments (II) are equivalent to those of predicate devices, although there is a slight difference in the indications for use statement of the subject device compared to the predicate with respect to implant compatibility. There are minor technological differences between the subject and predicate devices. The results of bench testing support the conclusion that risks associated with these technological changes have been adequately mitigated. Therefore, substantial equivalence of Klockner Dental Implant Abutments (II) to the predicate devices may be established.
