Indications for Use

This application provides for revision of Astra Tech Dental Implants labeling allowing the option of immediate function. The intended use for this device is to provide support for prosthetic constructions for fully and partially edentulous arches using one or two stage surgical procedures.

Device Story

Astra Tech Dental Implants are root-formed threaded screws composed of commercially pure titanium. Device provides support for prosthetic constructions in fully or partially edentulous arches. Used in single or two-stage surgical procedures. Allows for immediate placement and function on single or multiple tooth applications, provided patient has sufficient bone stability (type I or II) and appropriate occlusal loading. Multiple tooth applications may be splinted with a bar. Device is used by dental professionals in a clinical setting to restore chewing function. Output is the physical implant structure which serves as an anchor for dental restorations. Clinical benefit is the restoration of chewing function through immediate loading.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on design similarities and technological characteristics identical to the predicate device.

Technological Characteristics

Root-formed threaded screws; material: commercially pure titanium; single or two-stage surgical application; intended for immediate or delayed loading; no changes to physical design or materials from previous versions.

Indications for Use

Indicated for single-stage or two-stage surgical procedures and cement or screw retained restorations. Intended for immediate placement and function on single or multiple tooth applications in patients with sufficient bone stability (type I or II bone) and appropriate occlusal loading to restore chewing function. Multiple tooth applications may be splinted with a bar.

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.

#### Identification of legally market dev

Various Brånemark System Dental Implant products, submitted by Nobel BioCare under 510(k) K022562

#### Description of Device

The Astra Tech Dental Implants are root-formed threaded screws made from commercially pure titanium.

The indications and use for the components are not different from similar components of the predicate device.

#### Intended Use

This application provides for revision of Astra Tech Dental Implants labeling allowing the option of immediate function. The intended use for this device is to provide support for prosthetic constructions for fully and partially edentulous arches using one or two stage

# surgical procedures.

#### Indications for use

The Astra Tech Implants - Dental System are for single-stage or twosurgical procedures and cement or screw retained restorations. The The Astra Tech Implants - Dental System are intended for immediate placement and function on single tooth and/or multiple tooth applications recognizing sufficient bone stability (type I or II bone) and appropriate occlusal loading, to restore chewing function. Multiple tooth applications may be splinted with a bar.

#### Comparison of technological characteristics.

The technological characteristics of the Astra Tech Dental Implants remain unchanged. This application does only provide for a change in labeling allowi the option of immediate function.

Substantial equivalence of the Astra Tech Dental Implants is based on design similarities between the predicate device and the device in this application. The proposed and the predicate device are very similar in terms of material, size and basic design.
