Intended Use

The Thommen SPI® Dental Implant System is intended to be surgically placed, either immediately or delayed, in the bone of the maxillary and/or mandibular arch to provide support for crowns, bridges or overdentures. SPI® Dental Implants can be loaded immediately if they are for crowns, bridges or overdentures. SPI® Dental Implants can be loaded immediately if they are for crowns, bridges or overdentures in the mandibular arch or six implants in the maxillary arch.

Device Story

SPI® Dental Implant System, TST Surface, is a self-tapping, root-form, endosseous dental implant; manufactured from commercially pure grade titanium. Device features smooth machined transgingival portion and TST-treated surface for bone contact. Surgically placed by dental professionals in clinical settings to support prosthetic restorations (crowns, bridges, overdentures). Immediate or delayed loading protocols supported. TST surface modification intended to enhance osseointegration. Device provides structural foundation for dental rehabilitation, improving patient masticatory function and aesthetics.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on design, material, and intended use similarities to the predicate device.

Technological Characteristics

Endosseous root-form dental implant; material: commercially pure grade titanium (ASTM F67, ISO 5832-2); surface: TST treatment; form factor: self-tapping; sterilization: gamma irradiation (25 kGy).

Indications for Use

Indicated for patients requiring dental restoration via crowns, bridges, or overdentures in the maxillary or mandibular arch. Contraindicated for SPI® CONTACT and ELEMENT implants (ø 3.5 mm) in areas subject to pronounced rotation or large bending movements, specifically: posterior teeth restoration, single-tooth restoration of canines and central incisors in the upper jaw, and applications involving retentive anchors.

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.
