Intended Use

DenTack PYRAMIDION Dental Implants and Prostheses are intended for surgical placement in the maxilla and/or in the mandible to provide a means for prosthetic attachment in single tooth restorations and in partially or fully edentulous jaws utilizing conventional, delayed or immediate loading when good primary stability is achieved and with appropriate occlusal loading. Implants in 5-6mm length are indicated for delayed loading only.

Device Description

DenTack has developed a range of expandable dental implants made of titanium (the most common material for dental implants) to serve the need of patients that require partial or complete tooth restoration.

The implant is placed so its end is in the trabecular (spongy) bone like any other implant. Once in place, the apical portion of the implant is expanded to achieve increased contact surface area with the surrounding bone.

The system also includes various accessories that are attached to the implant. The PYRAMIDION has an external hex connection with 0.7mm height and 2.7mm hex with a distinct projection externally to the implant body. The connection between the prosthetic part to the upper platform of the implant interacts with a recessed plain of 15-degrees into the upper platform of the implant body while it is projected from the prosthetic part.

All DenTack's implants are made of biocompatible Titanium. Prostheses and Surgical components are made of same Titanium alloy, stainless-steel and polymers.

DenTack's PYRAMIDION Implants with are the subject of this submission are available in outer diameter (OD) of 4.1 mm and in length of 5 and 6 mm.

DenTack's Prostheses and dimension ranges are identified as follows:
Metal Housing: 3.3 mm Height
Plastic Cup: 2.7 mm Height
Straight Multi-Unit Sleeve: 11 mm Height
Straight Multi-Unit Screw: 2.3 mm Diameter
Angled Abutments 15° And 22.5°: Length: 7 mm – 9 mm
Angled Abutments 15° Large: Total Length: 9 mm – 12 mm
Ball Attachments: 2, 3 and 4 mm Height
Direct Screw Platform
Straight Abutments 2, 3, 8.5 mm Length
Straight Multi-Unit Abutments 2, 3 and 4 mm Length
Angled Multi Unit Abutments 17° and 1.5 and 3 mm Length
Healing Caps 3, 4, 5 and 6 mm
Cover Screw

The Direct Screw Platform is to be used with a burn-out plastic sleeve for ensuring a minimum post height of 4 mm (with no angular correction).

Like the QUAD implants cleared under K152188, the subject PYRAMIDION implants expansion is performed using a reusable Expansion Tool and Ratchet Torque).

AI/ML Overview

The provided text is a 510(k) summary for the DenTack PYRAMIDION Dental Implants and Prostheses. It describes the device, its intended use, and comparative testing performed to demonstrate substantial equivalence to predicate devices. However, this document does not describe a study involving an AI/Machine Learning device or its acceptance criteria and performance metrics.

The document primarily focuses on mechanical, physical, and biocompatibility testing of dental implants and prostheses, comparing them to legally marketed predicate devices. It covers aspects like:

  • Fatigue testing (ISO 14801): To assess durability.
  • Surface analysis (SEM): To characterize the implant surface.
  • Implant removal after expansion: To evaluate interaction with artificial bone.
  • Minimal rotation torque after placement and expansion: To assess stability.
  • Partially expanded implant reciprocating effect test: To evaluate effects of rotation.
  • Biocompatibility (ISO 10993): To ensure biological safety.
  • Sterilization validation (Gamma and Steam): To ensure sterility.
  • Cleaning validation: For reusable tools.
  • Shelf life validation: To confirm sterility maintenance over time.
  • Comparative pull-out test (ASTM F543): To assess mechanical strength.
  • Comparative bone to implant contact surface area analysis: To compare integration potential.
  • Implant surface area analysis: For physical characteristics comparison.

Therefore, I cannot provide the requested information regarding AI/ML device acceptance criteria and performance, as the document does not contain any details about an AI/ML component or study.

The questions posed (e.g., sample size for test set, number of experts for ground truth, MRMC study, standalone algorithm performance) are highly specific to AI/Machine Learning model validation in a medical context, which is not described in this 510(k) summary for dental implants.

§ 872.3640 Endosseous dental implant.

(a)
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.(b)
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.
