Intended Use

ZirAce™ abutments are indicated for use in partially edentulous patients requiring prosthetic devices and/or endosseous implants to restore chewing function. They are especially applicable to anterior or canine teeth where the typical titanium color may show through the gum. In addition to the Branemark (Nobel Biocare) implants, the ZirAce™ abutments hexagon connector fits the external hexagon of the following implants: 3i , Lifecore Biomedical , . Sterngold Implamed. .

Device Story

ZirAce is a ceramic dental abutment composed of yttrium-stabilized zirconium oxide with added niobium oxide for color and property enhancement. Device is intended to be cemented or screw-fastened to endosseous dental implants to provide a foundation for dental prostheses. Used by dental professionals to restore mastication in edentulous or partially edentulous patients. Radio-opaque for visualization. Provides aesthetic alternative to titanium abutments in anterior/canine regions.

Clinical Evidence

Bench testing only. Physical properties including compressive strength, fracture toughness, and durability were tested in accordance with ISO 14801 'Dynamic Continuous Fatigue Test.' Biocompatibility of the material was evaluated and found equivalent to common tetragonal yttrium-stabilized zirconia.

Technological Characteristics

Ceramic abutment composed of yttrium-stabilized zirconium oxide with niobium oxide. Radio-opaque. Designed for compatibility with external hexagon implant connections. Tested per ISO 14801 for dynamic continuous fatigue. Material is established in hip-implant and dental prostheses applications.

Indications for Use

Indicated for partially edentulous patients requiring prosthetic devices and/or endosseous implants to restore chewing function, particularly for anterior or canine teeth where titanium color aesthetics are a concern.

Regulatory Classification

Identification

An endosseous dental implant abutment is a premanufactured prosthetic component directly connected to the endosseous dental implant and is intended for use as an aid in prosthetic rehabilitation.

Special Controls

Submitter: Phone: 82-(0)31-527-6940. I. Classification Names and numbers: Endosscous dental implant abutment, code NHA,. II. Common/Usual Name: Abutment, implant abutment III. Proprietary Names: Zir Ace™ IV. Establishment Registration Number: Foreign, in process V. Classification: These products have recently been classified by the Dental Products Panel into 21 CFR 872.3630, Class II. VI. Device Description: ZirAce "" is a ccramic abutment composed of zirconium oxide stabilized with yttrium oxide, and containing niobium oxide to improve the properties and color. The zirconium oxide stabilized with yttrium oxide ceramic has been used for about 25 years as hip-implant and other prostheses and is capable of machining by modern CAD-C'AM methods. Various versions of this ceramic have been cleared for dental uses as inlays onlays and vencers by Dentronic in K971414 and for such materials and crowns and copings by Cynovad in K033227 and Medin Tech in K043472. The material is radio-opaque, for ready visualization. VII. Substantial Equivalence: Zir Ace" is substantially equivalent, and nearly identical, to the Procera Abutment Branemark, cleared in K042658. It is equivalent to several other ceramic abutments, such as the Esthetic Zirconia Abutment (K031719), the Astra Tech Dental Implants-Ceramic abutment (K023631) and others such as the Ceramic Abutment (K9132255), the Procera Abutment System (K974150), the 3i Dental Abutment (K032263), and the Sterngold Implant (K081516). The material from which the Zir Ace" abutment is manufactured is couvalent to the common yttrium stabilized zircoma used in Denzir cleared by Dentronic AB in K984201 and Cynovad Zircon (K02327). This has been demonstrated by extensive physical tests summarized in Appendix IV and provided from the literature in Appendix V. The "510(k) "Substantial Equivalence" Decision-Making Process (Detailed) from ODE Guidance Memorandum #86-3 was followed as described below: 1. These products have the same intended_use, to be cemented or screw-fastened to endosseous dental implants to provide a basis for building a prostheses to provide mastication in edentulous or partly edentulous persons. (repl. p. 11) ### XI. {1}------------------------------------------------ - 2. The technological characteristics for this product are similar to those for the predicate devices and those currently on the market except for slight differences in composition. Physical properties, including compressive strength, fracture toughness, and durability have been thoroughly tested with physical tests and in accordance with ISO 14801 "Dynamic Continuous Fatigue Test." The biocompatibility of the material used has also been studied carefully; it has been found equivalent to the common tetragonal yttrium stabilized zirconia. - 3. Descriptive information provided shows that the materials from which this device is made are well established in the more demanding areas of hip implants and that they have been more well recognized for their broad use in dental structures. - 4. The FDA "Decision-Making Process" chart was used and appears in Appendix V.1.
