The purpose of this submission is to add components to the S.I.N. Dental Implant System, which includes components previously cleared K200992, K193096, K170398 and K170392.

This submission adds Interface Abutments and Healing Abutments to the S.I.N. Dental Implant System. The subject device Interface abutments are provided with MT 16º and CM11.5º connection compatible with the S.I.N. Dental implants.

Subject Device Interface Abutments

Subject device Interface Abutments are two-piece abutments for which the second part (or top half) is the ceramic superstructure. The second part is designed and manufactured using CAD-CAM techniques. The titanium component of the Interface Abutments has a cementable platform diameter of 3.5mm, 4.0mm, 4.5mm, or 5.5mm, cementable post-height of 4.0mm or 6.0mm, and a gingival height built into the titanium base component from 0.5mm to 4.0 mm. The two pieces of the Ti-Base are bonded using Panavia Universal Dual-Cure Cement (K150704), as referenced in K190936.

All subject devices are provided only in straight designs, with no pre-angled conventional abutments or pre-angled CAD-CAM abutments. No subject device abutment is to be customized to create an angled abutment or to correct for angulation, and no superstructure for use with any subject device Interface abutment (CAD-CAM) is to be fabricated to create a final abutment with angulation or to correct for angulation. Therefore, this model has a slight design difference to improve screw insertion and removal. It was purposely designed to optimize fixation and removal of the screw connection. This new presentation allows screw fixation even in cases of anterior aesthetic rehabilitation, avoiding the need to create screw access holes in the sublingual phase. However, it is confirmed that all implant-abutment interfaces are intended exclusively for straight configurations and are not indicated for any angled model. These minor differences in the exact dimensions of the subject device interface abutment as compared to the predicate device and reference devices do not impact safety, effectiveness, or substantial equivalence.

The subject device interface abutments with the CM11.5º interface are compatible with implants cleared in K200992, K221453, K211921 and K170392 in terms of abutment-implant connection. The subject device with the MT16º interface is compatible with implants cleared in K222231, K193096 and K170392 in terms of abutment-implant connection.

The design parameters for the CAD-CAM fabrication of patient-specific abutments from CADCAM Abutments are the same for the 11.5° CM implant connection and the MT 16° implant connection. The design limit parameters are:

• Minimum wall thickness – 0.5 mm
• Minimum abutment post height for single-unit restoration – 4.0 mm
• Maximum angle – 0°. Straight only
• Maximum angle for screw insertion/removal – 20º
• Maximum gingival height – 5.0mm
• Minimum Gingival Height – 0.5 mm
• Maximum allowable abutment Post Height – 6 mm
• Total Abutment Height – 10mm

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 subject device Interface Abutments are manufactured from titanium alloy (Ti-6Al-4V) conforming to ASTM F136 and the same zirconia that is specified for superstructures in K190396, and are to be used with subject abutment screws. All subject devices are provided sterile. All Interface abutments are provided sterile by gamma irradiation; the same sterilization method used in predicate device K190396 and in the additional devices K200992 and K170392.

All Interface abutments manufactured form titanium alloy are anodized using a standard anodization process is identical to the anodization process used on abutments cleared in K190396.

The subject device abutments screws are to be used with Interface Abutments present in this submission and they are substantially equivalent to material (titanium alloy) and designs to abutments screws cleared in K170392.

Subject Device Healing Caps

The subject device Healing Cap is substantially equivalent to the corresponding design Healing Cap cleared in K170392. The subject device healing cap is designed for the healing period between implant placement and final abutment placement and is not intended to support a temporary prosthesis.

All Healing Caps are provided sterile by gamma irradiation; the same sterilization method used in predicate device K170392 and additional predicate device K200992.

All subject device components are provided sterile by gamma irradiation, the same sterilization method used in K190936, K170392 and K200992.

The provided FDA 510(k) Clearance Letter for Sherlock Dental Implant Abutment does not contain the information requested regarding acceptance criteria and a study proving the device meets those criteria.

This document describes the device's indications for use, its substantial equivalence to predicate devices, and the non-clinical data reviewed by the FDA for clearance. However, it does not detail specific acceptance criteria or an associated study demonstrating compliance with those criteria.

The "Performance Data" section lists several types of non-clinical data submitted, such as static and fatigue testing according to ISO 14801, a reverse engineering study, biocompatibility testing, cleaning and sterilization validation, and an MRI review. These are the studies performed to support the substantial equivalence claim, but the FDA letter does not specify quantitative acceptance criteria for these tests nor does it report specific performance outcomes that directly address such criteria.

Therefore, I cannot populate the requested table or provide details for points 1-9 based solely on the provided text. The document focuses on demonstrating substantial equivalence to previously cleared devices rather than presenting a performance study against predefined acceptance criteria.
