The abutments consist of healing abutments, temporary abutments, straight abutments, and an overdenture attachment system that consists of abutments, denture housings, and retention inserts, and TiBase abutments with screws. The subject device Vega Mimetic® Healing Abutments are designed to be connected to the implant during the healing period between implant placement and final abutment placement. Restorations are not placed on the healing components. The healing components are compatible with the Klockner Vega Implant System. They are offered in coronal diameter of 3.6 mm and with gingival heights of 2.0, 3.0, and 5.0 mm. The healing abutments attach to the dental implant with an integrated apical threaded portion. They are manufactured from titanium alloy and are color anodized to aid in identification. The subject device Vega Mimetic® Temporary Abutments are straight, prepable abutments designed to retain a temporary cemented prosthesis. They are provided straight only and not intended to provide any angulation correction. They are compatible with the Klockner Vega Implant System. The abutment has a hex connection and attaches to the implant with a separate screw, previously cleared under K153098. The abutments are offered in a prosthetic platform diameter of 3.6 mm and a 7.0 mm post height, with gingival heights of 1.0, 2.0, and 3.0 mm. They are manufactured from titanium alloy and are anodized on a portion of the surface for identification purposes. The subject device Vega Straight Permanent Abutments are designed for single-unit and multipleunit cement-retained restorations. The straight abutments are compatible with the Klockner Vega Implant System. They are available in an engaging and a non-engaging connection. The engaging design has a hex connection and attaches to the implant with a separate screw. The non-engaging design has a threaded apical portion. They are offered in a prosthetic platform diameter of 4.2 mm and gingival heights of 1.0, 2.0, and 3.0 mm, with no angulation. They are manufactured from titanium alloy and anodized on a portion of the surface for identification purposes. The subject device K-LOCK Overdenture Attachment System is compatible with the Klockner Vega and Essential Cone Implant System and consists of abutments, retention inserts, and denture housings for attachment of prostheses to endosseous dental implants. All K-LOCK abutments are made of titanium alloy and have the same coronal ridge retention design that attaches to the overdenture component by an interference (snap) fit. The threaded apical end of the abutment connects to the implant and is specific to each compatible implant system and diameter. The {5}------------------------------------------------ 510(k) Summary Page 3 of 8 retention connection is designed to accommodate a path of insertion on implants that are divergent up to 40° (with 20°on each side). K-LOCK abutments are provided with a titanium carbonitride (TiCN) coating and are available in cuff (gingival) heights up to 6 mm, with a minimum implant interface diameter of 3.0 mm. A thin titanium carbonitride (TiCN) coating is applied to the abutments in the area that contacts gingival tissue and in the area that contacts the retention inserts. Subject device TiBase Abutments are two-piece abutments composed of a bottom titanium component and are designed for fabrication of a patient-specific CAD/CAM zirconia superstructure on which a crown may be placed. The patient-specific CAD/CAM zirconia superstructure is the top-half of the two-piece abutment. They also may be used for support of a crown directly on the abutment. There are two types of TiBase Abutments; TiBases that attach directly to the implant, and TiBases that attach to previously-cleared abutments from the sponsor (similar to a prosthetic coping). All patient-specific custom abutment fabrication for TiBase Abutments is by prescription on the order of the clinician. Zirconia superstructures for use with the subject device TiBase Abutments will be made at a SOADCO validated milling center under FDA quality system regulations and the material will conform to ISO 13356 Implants for surgery – Ceramic materials based on yttria-stabilized tetragonal zirconia (Y-TZP). The cement recommended in labeling for bonding of superstructures is Panavia F 5.0 cement by Kuraray Noritake Dental, cleared under K183537. TiBase Abutments that attached directly to the implant are available in an engaging design and a non-engaging design. TiBase Abutments are made of titanium alloy. The TiBase Abutments are provided in four different designs: MedproTiBase, Mimetic TiBase, EC Essential TiBase, and SK2 Medpro TiBase. The EC Essential TiBase is a line extension from previously cleared TiBases for Cerec (K170022). The MedproTiBase abutments are anodized gold. The Mimetic TiBase abutments are coated with a thin layer of zirconium nitride (ZrN). The design parameters for the CAD/CAM zirconia superstructure to be used on MedproTiBase Abutments are as follows: Minimum wall thickness – 0.5 mm Minimum post height - 4.0 mm1 Minimum gingival height - 0.5 mm Maximum gingival height – 6.0 mm All zirconia superstructures are for straight abutments only 1 For devices 84 01 36 must be a minimum post height of 5.5 mm The design parameters for the CAD/CAM zirconia superstructure to be used on Mimetic TiBase Abutments are as follows: Minimum wall thickness - 0.35 mm Minimum post height - 4.2 mm Minimum gingival height - 0.5 mm Maximum gingival height - 6.0 mm All zirconia superstructures are for straight abutments only {6}------------------------------------------------ 510(k) Summary Page 4 of 8 The design parameters for the Sirona Dental CAD/CAM system to be used on EC Essential TiBase Abutments for Cerec® are as follows: Minimum wall thickness - 0.8 mm Minimum post height - 5.2 mm Minimum gingival height - 0.5 mm Maximum gingival height – 6.0 mm Maximum angulation of the final abutment - 20° TiBase Abutments that attached directly to previously-cleared angled abutments (like a coping) from SOADCO S.L. are available in an engaging design and a non-engaging design. These TiBase Abutments have no angulation, but some may be placed on abutments that are angled up to 30°. TiBase Abutments are made of titanium alloy and anodized gold. The TiBase Abutments are provided in three different designs: Permanent Vega Medpro, Essential Cone 25° Medpro, and Essential Cone Multi-Cone Medpro. The differences between these designs are primarily related to the compatible implant system or related to connection to a straight or angled abutment. The design parameters for the CAD/CAM zirconia superstructure to be used on Medpro TiBase to Abutments are as follows: Minimum wall thickness - 0.5 mm Minimum post height - 4.0 mm1 Minimum gingival height - 0.5 mm Maximum gingival height - 6.0 mm Not intended to provide angulation correction 1 For devices 84 01 26 and 84 01 27 must be a minimum post height of 5.5 mm ### PERFORMANCE DATA Non-clinical testing data submitted to demonstrate substantial equivalence included: - Sterilization validation according to ISO 17665-1 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 Sterilization of health care products — Moist heat — Part 2: Guidance on the application of ANSI/AAMI/ISO 17665-1 was leveraged from previously cleared submissions K151194 and K170022. - Biocompatibility testing for Klockner TiBase, straight abutments, healing abutments, temporary abutments, and denture housing subject devices leveraged from K170022 and K151194. - Biocompatibility testing for TiCN coated K-Lock Abutments and ZrN coated Mimetic .
