Indications for Use
SPI® System Dental Implants are for one-stage or two-stage surgical procedures. SPI System Dental Implants are intended for immediate placement and function on single-tooth and/or multiple tooth applications when good primary stability is achieved and with appropriate occlusal loading, to restore chewing function. Multiple tooth applications may be rigidly splinted. In the case of edentulous patients, four or more implants must be used in immediately loaded cases.
Device Story
SPI System Dental Implants are self-tapping, root-form, endosseous dental implants; manufactured from commercially pure grade titanium. Used by dental surgeons in clinical settings for one-stage or two-stage surgical procedures. Implants provide foundation for single or multiple tooth restorations; restore chewing function. Device allows for immediate functional loading when primary stability is achieved; supports reduced six-week healing protocol compared to conventional twelve-week standards. Clinical benefit includes faster restoration of dental function for patients.
Clinical Evidence
No clinical data provided; substantial equivalence based on design principles and intended use.
Technological Characteristics
Self-tapping, root-form, endosseous dental implants; material: commercially pure grade titanium. Dimensions: includes 3.5 mm diameter variants. Sterilization: not specified. Connectivity: N/A. Software: N/A.
Indications for Use
Indicated for one-stage or two-stage surgical procedures for single or multiple tooth replacement to restore chewing function. Suitable for immediate placement and function when primary stability is achieved and occlusal loading is appropriate. Edentulous patients require four or more implants for immediate loading. Contraindicated for 3.5mm diameter ELEMENT and CONTACT implants in areas with high rotation/translation (bending) forces, specifically: posterior teeth in upper/lower jaw, single-tooth restoration of upper canines/central incisors, 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.
