• Attributes: Therapeutic

Intended Use

To provide immediate transitional splinting stability or ongoing fixation of new/ existing crown, bridge and denture instillations in partial or fully endentulous settings.

Device Story

IMTEC Sendax MDI is a self-tapping titanium screw (1.8 mm width; 13, 15, 18 mm lengths) used as a dental anchor post. Operated by dental professionals in clinical settings, the device is surgically placed into bone to provide immediate transitional stability or fixation for dental prostheses. It serves as a temporary support during conventional implant integration, a stabilizer for interim prostheses in graft sites, or a low-commitment introductory system for patients. By providing stable anchorage, the device enables improved mastication, speech, and patient comfort. The device is intended for prescription use.

Clinical Evidence

No clinical data provided; substantial equivalence is based on technological characteristics and intended use.

Technological Characteristics

Self-tapping titanium screw; 1.8 mm diameter; 13, 15, and 18 mm lengths. Mechanical fixation device. Biocompatible titanium construction. Sterilization method not specified.

Indications for Use

Indicated for partial or fully edentulous patients requiring intra-bony and inter-radicular transitional support for crown, bridge, and denture fixation. Used for temporary support during conventional implant integration, stabilization of interim prostheses in graft sites, and as an introductory system for apprehensive patients or medically compromised/terminally ill patients to improve mastication and speech. Contraindicated in patients with local infection, vascular impairment, uncontrolled diabetes, chronic high-dose steroid use, clotting disorders, anticoagulant therapy, metabolic bone disease, or other systemic disorders affecting bone/wound healing.

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.
