• Submission Type: Traditional
• Regulation: 21 CFR 872.3640
• Device Class: Class 2

Intended Use

The Atlantis abutment is intended for use as an accessory to an endosseous implant to support a prosthetic device in a partially or completely edentulous patient. It is intended for use to support single and multiple tooth prostheses, in the mandible or maxilla. The prostheses can be screw or cement retained to the abutment. The abutment screw is intended to secure the abutment to the endosseous implant. The impression coping is intended to transfer the position of the implant in the oral cavity to a working cast. The impression coping screw is intended to temporarily secure the impression coping to either the implant fixture or the analog fixture.

Device Story

Atlantis Abutment System serves as interface between endosseous dental implants and prosthetic restorations. Dentist prescribes abutment; Atlantis designs and manufactures custom abutment based on prescription. Abutment attaches to implant via Atlantis screw; supports screw-retained or cement-retained prostheses. Impression copings facilitate transfer of implant position to working casts. System used in dental clinics by dentists to restore oral function in edentulous patients.

Clinical Evidence

No clinical data provided; substantial equivalence is based on technological and design identity to predicate devices.

Technological Characteristics

Endosseous implant abutment system. Components include abutment, abutment screw, and impression coping. Designed for interface with endosseous implants in mandible or maxilla. Materials and design are identical to predicate Lifecore Biomedical UCLA abutment system.

Indications for Use

Indicated for partially or completely edentulous patients requiring single or multiple tooth prostheses supported by endosseous implants in the mandible or maxilla.

Regulatory Classification

Identification

An endosseous dental implant is a prescription device made of a material such as titanium or titanium alloy that is intended to be surgically placed in the bone of the upper or lower jaw arches to provide support for prosthetic devices, such as artificial teeth, in order to restore a patient's chewing function.

Special Controls

*Classification.* (1) Class II (special controls). The device is classified as class II if it is a root-form endosseous dental implant. The root-form endosseous dental implant is characterized by four geometrically distinct types: Basket, screw, solid cylinder, and hollow cylinder. The guidance document entitled “Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Implant Abutments” will serve as the special control. (See § 872.1(e) for the availability of this guidance document.)(2) *Classification.* Class II (special controls). The device is classified as class II if it is a blade-form endosseous dental implant. The special controls for this device are:(i) The design characteristics of the device must ensure that the geometry and material composition are consistent with the intended use; (ii) Mechanical performance (fatigue) testing under simulated physiological conditions to demonstrate maximum load (endurance limit) when the device is subjected to compressive and shear loads; (iii) Corrosion testing under simulated physiological conditions to demonstrate corrosion potential of each metal or alloy, couple potential for an assembled dissimilar metal implant system, and corrosion rate for an assembled dissimilar metal implant system; (iv) The device must be demonstrated to be biocompatible; (v) Sterility testing must demonstrate the sterility of the device; (vi) Performance testing to evaluate the compatibility of the device in a magnetic resonance (MR) environment; (vii) Labeling must include a clear description of the technological features, how the device should be used in patients, detailed surgical protocol and restoration procedures, relevant precautions and warnings based on the clinical use of the device, and qualifications and training requirements for device users including technicians and clinicians; (viii) Patient labeling must contain a description of how the device works, how the device is placed, how the patient needs to care for the implant, possible adverse events and how to report any complications; and (ix) Documented clinical experience must demonstrate safe and effective use and capture any adverse events observed during clinical use.
