This document is a 510(k) Summary for a medical device (DESS Dental Smart Solutions). It describes the device, its intended use, a comparison to predicate devices, and the non-clinical data submitted to demonstrate substantial equivalence. It does not contain information about acceptance criteria or studies proving device performance against such criteria in the context of an AI/ML powered device.
Based on the provided text, the device in question is not an AI/ML powered device. It is a set of dental implant abutments and related components. Therefore, the questions related to AI/ML device performance (like acceptance criteria, sample size for test/training sets, expert ground truth, MRMC studies, standalone performance, etc.) are not applicable to this document.
The "Performance Data" section (page 8, {8} in your indexing) details the non-clinical tests performed:
- MR Safety Evaluation: Non-clinical analysis to evaluate the subject devices in the MR environment using scientific rationale and published literature. This included assessing magnetically induced displacement force and torque.
- Mechanical Testing: Conducted according to ISO 14801 to support the performance of the subject device abutments with angulation.
- Biocompatibility: Referenced from previous K-submissions (K240208, K233316, and K222288).
- Sterilization Validation:
- Moist Heat Sterilization: Referenced from K240208, validated to a sterility assurance level of 10^-6 by the overkill method (ANSI/AAMI/ISO 17665-1 and 17665-2).
- Gamma Irradiation: Referenced from K240208, validated to a sterility assurance level of 10^-6 using method VDmax25 (ISO 11137-1 and ISO 11137-2).
- Bacterial Endotoxin Testing: According to ANSI/AAMI ST72, demonstrating < 20 EU/device.
- Shelf Life Testing: Samples tested after accelerated aging equivalent to five (5) years of real-time aging per ASTM F1980, including testing of packaging sterile barrier and sterility.
- Reverse Engineering Dimensional Analysis: Referenced from K212628, used to establish dimensions and tolerances for subject abutments and screws to fit OEM implants, demonstrating compatibility.
The document explicitly states: "No clinical data were included in this submission."
Therefore, I cannot provide the requested table or information because the device described in the provided text is a physical medical device (dental implants and abutments), not an AI/ML-powered one. The acceptance criteria and study designs described in your request are relevant to AI/ML software (like diagnostic algorithms), not to a physical implantable device like this one.

SUBJECT DEVICE DESCRIPTION
The purpose of this submission is to add components to the DESS Dental Smart Solutions system, which includes dental implants, abutments, and prosthetic components cleared previously in various submissions. The previously cleared abutments and prosthetic components are compatible with a variety of original equipment manufacturer (OEM) dental implants as well as DESS Dental Smart Solutions dental implants. This submission adds various abutments compatible with the Neodent GM implant line.
The subject device abutment designs include Healing Abutments, Ti Base Abutments, AURUM Base Abutments, C-Base Abutments, Multi-Unit Abutments (straight and angled), Cement-retained Abutments (straight and angled), Pre-Milled Blank Abutments, DESSLoc Abutments (Locator-type abutments), and abutment screws.
Subject Device Designs
Healing Abutments are provided in gingival heights from 0.8 mm to aid in contouring the gingiva during healing. Healing Abutments are made of titanium alloy (Ti-6Al-4V).
Temporary Abutments are provided for single-unit and multiple-unit restorations, the former with engaging connections to the implants and the latter with non-engaging connections. All Temporary Abutments have a gingival height from 0.8 mm to 3.5 mm and are made of titanium alloy (Ti-6Al-4V), and with a prosthetic platform diameter of 3.5 mm or 4.5 mm.
Ti Base Abutments are provided in engaging and non-engaging designs for custom abutment fabrication of a CAD-CAM zirconia superstructure on which a crown may be placed. They also may support a ceramic hybrid abutment in which the crown is included in the design of the zirconia abutment ceramic superstructure.. The two-pieces of the Ti Base Abutment which compose the final abutment consists of the pre-manufactured titanium base component composed of titanium alloy and the CAD-CAM patient matched superstructure or hybrid abutment crown composed of zirconia. The cement recommended for bonding of superstructures is Multi-Link cement by Ivoclar Vivadent (K130436). Ti Base Abutments are manufactured from titanium alloy (Ti 6A14V) with the SelectGrip® surface.
Ti Base Abutments also may support a ceramic hybrid abutment in which the crown is included in the design of the zirconia abutment ceramic superstructure. When used for a direct crown, Ti Base abutments may be used with POM burn out sleeve, an exempt laboratory component not a subject of this submission, that is available for laboratory fabrication of the prosthesis. Ti Bases are not intended for angulation correction when used with a POM burn-out sleeve.
{6}------------------------------------------------
The design parameters for the CAD-CAM zirconia superstructure to be used on Ti Base Abutments are: Minimum wall thickness - 0.4 mm Minimum post height for single-unit restoration (length above the abutment collar/gingival height) – 4.2 mm Minimum gingival height - 0.5 mm Maximum gingival height - 6.0 mm Maximum angulation - for Ti Base with gingival height 0.8 mm or 2.5 mm - 30° for Ti Base with gingival height 3.5 mm or 4.5 mm - 0°
By definition, the abutment post height is considered by FDA to be the "stump" portion above the gingival collar, to which the restorations attach.)
All patient-specific custom abutment fabrication for Ti Base Abutments, AURUM Base Abutments, and C-Base Abutments (described below) is by prescription on the order of the clinician. All zirconia superstructures for use with the subject device Ti Base, AURUM Base, and C-Base Abutments will be made at a Terrats Medical validated milling center under FDA quality system regulations, and the zirconia material will conform to ISO 13356.
AURUM Base Abutments are provided in engaging and non-engaging designs. The two-pieces of the AURUM Base Abutment which compose the final abutment consists of the pre-manufactured titanium base composed of titanium alloy and the CAD-CAM patient matched superstructure composed of zirconia. The design of the AURUM Base Abutment allows for easier instrument access to the abutment screw and allows for placement of the screw channel out of the esthetic region of the restoration. AURUM Base Abutments are provided with a prosthetic platform diameter of 4.0 mm, 4.5 mm, with gingival heights (in the base) of 0.8 mm, 1.5 mm, or 2.5 mm. When used for a single-unit restoration the AURUM Base is to be used with a superstructure to create a minimum post height of 4.0 mm.
AURUM Base Abutments are provided in two (2) designs, each for engaging and non-engaging connections. One design has a conical taper below the prosthetic platform that engages the compatible Neodent GM implant, this is the same design as cleared in K212628. The second design has a flat surface below the prosthetic platform that seats directly on the top of the compatible Neodent GM implant.
AURUM Base Abutments are manufactured from titanium alloy (Ti 6Al 4V) and anodized a gold color, and the SelectGrip® surface to aid in bonding retention. The AURUM Base Abutments, including the titanium alloy, anodization treatment, and SelectGrip® surface is similar to that of DESS AURUM Base Abutments cleared in K240208.
The design parameters for the CAD-CAM zirconia superstructure to be used on AURUM Base Abutments are: Minimum wall thickness - 0.4 mm Minimum post height for single-unit restoration (length above the abutment collar/gingival height) – 4.0 mm Minimum gingival height - 0.5 mm Maximum gingival height - 6.0 mm Maximum angulation - 30°
C-Base Abutments are provided in engaging and non-engaging designs. C-Base Abutments are two-piece abutments designed to support a custom CAD-CAM zirconia superstructure on which a single-unit or multi-unit restoration may be placed. The ceramic superstructure produced through CAD-CAM is the second part of the two-piece abutment. The C-Base Abutment also may support a ceramic hybrid abutment in which the crown is included in the design of the zirconia abutment ceramic superstructure.
The C-Base Abutment prosthetic post is 4.68 mm, and the gingival height is 0.8 mm. All patient-specific custom abutment fabrication is by prescription on the order of the clinician. C-Base Abutments are made of titanium alloy (Ti-6Al-4V) with anodization and a SelectGrip® surface.
C-Base Abutments also may support a ceramic hybrid abutment in which the crown is included in the design of the zirconia abutment ceramic superstructure. When used for a direct crown, C-Base abutments may be used with POM

{9}------------------------------------------------
EQUIVALENCE TO MARKETED DEVICES
The subject device abutments are substantially equivalent in intended use to the primary predicate device K240208, and the reference devices, K222288 and K170588. All are intended for use with endosseous dental implants in the maxilla and mandible to provide functional and esthetic rehabilitation of the edentulous maxilla and mandible. Except for the list of compatible OEM implants and sizes, the Indications for Use Statement (IFUS) for the subject device is substantially equivalent to that of K240208. K22288, and K170588.The lists of the specific OEM implant compatibilities in the IFUS differ between the subject device and the primary predicate and the reference devices.
The primary predicate device K240208 and the reference devices, K222288 and K170588, are in support of substantial equivalence of the subject device designs, material, manufacturing, and biocompatibility. All subject device abutments and screws are similar to or identical in design, materials, and technological characteristics to corresponding abutments of the primary predicate device K240208 and the reference devices K22288 and K170588. The subject submission, K240208, and K222288 all include abutments manufactured from Ti-6Al-4V alloy conforming to ASTM F136. The subject abutments are anodized by a process that is identical to that used on abutments cleared in K240208. Subject Ti Base Abutments. AURUM Base Abutments, and C-Base Abutments have a SelectGrip® surface to aid in bonding retention that is identical to the surface used on abutments cleared in K240208. All zirconia superstructures for use with the subject device Ti Base Abutments, AURUM Base Abutments, and C-Base abutments is the same zirconia material used for components cleared in K240208. The cement recommended for bonding of superstructures is Multi-Link cement by Ivoclar Vivadent (K130436). The subject Multi-Unit Abutments and DESSIoc Abutments are available with and without a zirconium nitride (Zr) coating that is identical to the ZrN coating on abutments cleared in K222288. The subject abutments screws are manufactured from Ti-6A1-4V alloy.
The subject device abutment screws have similar or identical ranges of abutment-implant platform diameter, prosthetic platform diameter, and angulation as the components cleared in K240208, and K170588.
Selected subject device components are provided sterile by gamma irradiation and are packaged in a PETC blister with a Tyvek® Id. This is the same sterilization, packaging, and 5-year shelf life that was referenced in the primary predicate K240208. For the subject devices provided non-sterile, the previously validated moist heat cycle, referenced from the primary predicate K240208 is applicable to the non-sterile subject devices.
The risks associated with use of the subject device abutments with angulation (Ti Base Abutments, AURUM Base Abutments, C-Base Abutments, Multi-Unit Abutments, Cement-Retained Abutments, and Pre-Milled Blank Abutments) in combination with the compatible implants are mitigated by the mechanical testing provided in this submission.
CONCLUSION
Any differences in the technological characteristics between the subject device, the predicate device, and reference devices do not raise different questions of safety or effectiveness. The data included in this submission demonstrate substantial equivalence to the predicate and reference devices listed above.
Overall, the subject device has the following similarities to the primary predicate device and the reference devices:
- have the same intended use,
- use the same operating principles,
- incorporate the same basic designs, ●
- incorporate the same or very similar materials, and
- have similar packaging and are sterilized using the same materials and processes. ●
The basis for the belief of Terrats Medical SL that the substantially equivalent to the predicate devices is summarized in the following Table of Substantial Equivalence.
