All digitally designed abutments for use with Dentium CAD/CAM Abutments are intended to be sent to a Dentium-validated milling center for manufacture. ### DEVICE DESCRIPTION Dentium CAD/CAM Abutments are titanium abutments to be used in fabricating patient-specific abutments. Each patient-specific abutment is individually prescribed by the clinician. Dentium CAD/CAM Ti-Blank Abutments are abutments with a pre-manufactured precision interface and are used by a validated milling center to fabricate patient-specific abutments. Ti-Blanks are available in three cylinder diameters (10 mm, 14 mm, and 15.8 mm) and three connection designs (Hex, Long Hex). Dentium CAD/CAM Custom Abutments are patient-specific abutments fabricated by Dentium. Custom Abutments are available for fabrication in three connection designs (Hex, Long Hex, and Non-hex). Dentium CAD/CAM Abutments are available for four corresponding implant platform diameters (3.6 mm. 4.0 mm, 4.5 mm, 5.0 mm). Each abutment is supplied with a corresponding abutment screw, cleared previously in K141457. All subject device abutments are compatible with Implantium dental implants. ### PERFORMANCE DATA Non-clinical testing data submitted, referenced, or relied upon to demonstrate substantial equivalence included: steam sterilization validation according to ISO 17665-2, demonstrating a sterility assurance level (SAL) of 10 th; biocompatibility demonstrated by the referenced Dentium submission, K070228, using the same materials and manufacturing processes as the subject device; and dynamic compression-bending testing according to ISO 14801, showing mechanical performance equivalent to predicate devices. No clinical data were included in this submission. ## EQUIVALENCE TO MARKETED DEVICE The subject device is substantially equivalent in indications and design principles to the predicate devices shown above.

Both are cylindrical titanium abutments with a precision implant/abutment interface for use in fabricating a patient-specific abutment at a manufacturer-validated milling center. The subject device is different from the predicate device in implant/abutment interface, specific cylinder size, and specific abutment diameters. However, the subject device sizes are within the size range of the primary predicate. The subject device Custom Abutment is substantially equivalent to K103020 in design, function, manufacture and intended use. Both are patient-specific abutments fabricated by the manufacturer. The subject device is different from the predicate device in implant/abutment interface, specific abutment sizes and manufacturer. However, the subject device sizes are within the size range of the primary predicate. The final finished Custom Abutment differs from the Ti-Blank and primary predicate in manufacturing flow only. All subject device abutments and predicate abutments are by prescription order from a clinician, and have the same implant/abutment interface as the reference predicate K141457. All are compatible with Dentium Implantium implants (K041368). Subject device design parameters are substantially equivalent to K150203, K103020, and K092341. Minor differences in the language or in device-specific details of the indications for use statement for the subject device as compared to the predicate devices do not change the intended use of abutments to be used with endosseous dental implants for prosthetic rehabilitation in the maxilla and mandible. The subject device Indications for Use statement does not include a compatibility table because it is not claiming compatibility with other manufacturers' devices. Therefore, these minor differences in language do not affect the determination of substantial equivalence. {7}------------------------------------------------ Mechanical testing performed for the subject device shows that it is strong enough for its intended use and is equivalent to the predicate devices listed above. ## CONCLUSION The subject device and the predicate devices have the same intended use, have similar technological characteristics, and are made of similar materials. The subject devices encompass the same range of physical dimensions, including diameter, gingival height, and angle of the abutments. The subject and predicate devices are packaged in similar materials and are to be sterilized using similar methods. The data included in this submission demonstrate substantial equivalence to the predicate devices listed above.
