Intended Use

Intermezzo ™ Implant Systems is threaded one-piece implants designed for orthodontic one-stage surgical procedures in upper and lower jaw to provide a means of prosthetic attachment to restore a patient's chewing function. Intermezzo ™ Implant System consists of single-stage, root-form dental implants. The system is designed to provide immediate provisional implant to provide temporary support for prosthetic devices during the healing phase of permanent root form implants. Depends on a patient's quality of bone condition, Intermezzo ™ Fixtures are to be removed within six to ten weeks after the surgery. The system is intended for immediate placement in partially or fully edentulous mandibles and maxillae, in support of single or multiple-unit restorations including; cement retained, screw retained, or overdenture restorations.

Device Story

Intermezzo Implant System comprises threaded, one-piece, root-form endosseous dental implants, protective caps, and surgical instrumentation (drills, drivers). Used by clinicians in dental settings for immediate placement in edentulous mandibles/maxillae. Provides temporary support for provisional prosthetic devices (cement/screw-retained or overdentures) during the healing phase of permanent implants. Fixtures are removed 6-10 weeks post-surgery depending on bone condition. System maintains gingival contour; allows clinicians to select specific components per clinical situation.

Clinical Evidence

Bench testing only. Laboratory testing conducted to determine device functionality and conformance to design input requirements.

Technological Characteristics

Threaded, one-piece, root-form dental implants; material: titanium; surface treatment: sandblasted; sizes: 1.6mm, 2.0mm, 2.5mm, 3.1mm; includes protective caps and surgical instrumentation (lance, twist, and unification drills).

Indications for Use

Indicated for immediate loading in partially or fully edentulous mandibles and maxillae to serve as temporary support for provisional prosthetic devices during the healing phase of permanent endosseous 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.
