Device Story

Prepable Abutment System consists of dental prosthetic components (abutments and screws) for single or multiple tooth constructions; used in conjunction with dental fixtures in edentulous or partially edentulous patients; components are manually placed by clinicians during restorative dental procedures; system facilitates cemented bridge construction; provides structural interface between dental implant fixture and prosthetic restoration; benefits patient by restoring dental function and aesthetics.

Clinical Evidence

No clinical data provided; substantial equivalence based on design and material similarity to predicate devices.

Technological Characteristics

Commercially pure titanium construction; mechanical dental prosthetic components; includes prepable abutments and attachment screws; designed for integration with dental fixtures; non-electronic; no software.

Indications for Use

Indicated for use in fully or partially edentulous patients requiring cemented bridge construction via dental implants.

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.
