## Intended Use

The Opti-Max angled crown post for externally-hexed implants is intended to be used as an abutment for a cast crown, to be retained by cementation. The metal for this cast crown is to be composed of a computible formulation when in contact with Ti6A4V. If light retention is desired by the cinician zinc-oxide cement can be used, if stronger retention is desired, carboxylate cements of an be used. The cast crown seated on this crown post may be single and free-sanding, part of fixed bridgework, or connected to a bar structure for overdenture retention .

## Device Story

Opti-Max angled crown post serves as dental implant abutment; designed for externally-hexed implants. Device acts as interface between implant and cast crown; crown retained via cementation (zinc-oxide for light retention; carboxylate for strong retention). Compatible with Ti6A4V implant materials. Used by dental clinicians in clinical settings to facilitate prosthetic restoration; supports single crowns, fixed bridges, or overdenture bar structures. Benefits patient by providing stable foundation for dental prosthetics.

## Clinical Evidence

No clinical data provided; bench testing only.

## Technological Characteristics

Angled crown post for externally-hexed dental implants. Material compatibility specified for Ti6A4V. Mechanical retention via cementation.

## Regulatory 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.
