The synOcta® angled abutments are indicated for use in cases where the placement of the implant requires an angled reconstruction for an aesthetic result. The abutment can be used to restore crowns for single tooth replacements and bridges for bound situations.
The angled abutment is not to be used in conjunction with the ITI 15° angled implant as the total degree of angulation is 30 degrees or above.
The subject device of this 510(k) is the ITI® synOcta® Angled Abutment which is placed into the dental implant to provide support for a prosthetic reconstruction. The angled abutment is used for angulation correction in cases where the angle of placement of the dental implant requires an angled reconstruction for an aesthetic result.
The synOcta® abutment is available in 15° and 20° angles and is made from commercially pure Grade 4 titanium (cold worked) which conforms to ASTM Standard Specification F67. The abutment is provided non-sterile in medical grade heat-sealed packaging.
The basal portion of the modified angled abutment has an 8° conical taper which fits into the coronal portion of the ITI implants. The abutment is held in place with a screw located in the basal portion of the abutment. This screw is composed of titanium alloy. The abutment is manufactured out of a single piece of titanium. The screw and suspension ring are mounted into the basal portion of the abutment. The coronal aspect of the abutment has an occlusal thread for the impression coping and a lateral screwdriver access hole.
The provided text is a 510(k) summary for the synOcta® Angled Abutment, which is a dental implant accessory. This document focuses on demonstrating substantial equivalence to predicate devices rather than proving performance against specific acceptance criteria through a study. Therefore, much of the requested information regarding acceptance criteria, study details, sample sizes, ground truth establishment, and multi-reader comparative effectiveness studies is not present in this type of regulatory submission.
However, I can extract information related to the device description and the basis for its substantial equivalence.
Here's a breakdown of what can be inferred or explicitly stated from the provided document, and what is absent:
1. A table of acceptance criteria and the reported device performance
This information is not provided in the 510(k) summary. A 510(k) primarily focuses on demonstrating substantial equivalence to legally marketed predicate devices, not on presenting novel performance data against pre-defined acceptance criteria for a new clinical study. The device's performance is implicitly considered equivalent to the predicate devices.
2. Sample size used for the test set and the data provenance
Not applicable/Not provided. No specific "test set" for a performance study is mentioned. The submission relies on a comparison to predicate devices already on the market.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable/Not provided. This document does not describe a study involving expert-established ground truth for a test set.
4. Adjudication method for the test set
Not applicable/Not provided. No adjudication method is mentioned as there is no test set described for performance evaluation.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
Not applicable/Not provided. This is a dental implant abutment, not an AI-powered diagnostic device. Therefore, no MRMC study or AI assistance is relevant here.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
Not applicable/Not provided. This is a physical medical device, not an algorithm.
7. The type of ground truth used
Not applicable/Not provided. No ground truth for a performance study is mentioned. The "ground truth" for this submission is the established safety and effectiveness of the predicate devices.
8. The sample size for the training set
Not applicable/Not provided. This is not an AI/ML device; therefore, there is no "training set."
9. How the ground truth for the training set was established
Not applicable/Not provided. As there is no training set, this question is irrelevant.
Summary of Device and Equivalence Argument (derived from the provided text):
- Device Name: synOcta® Angled Abutment
- Intended Use: "The synOcta® angled abutment is indicated to be used in cases where the angle of placement of the implant requires an angled reconstruction for an aesthetic result. The abutment can be used to restore both crowns for single tooth replacements and bridges for bound situations."
- Description: Available in 15° and 20° angles, made from commercially pure Grade 4 titanium. It has an 8° conical taper, a titanium alloy screw, and features for impression coping and screwdriver access.
- Predicate Devices:
- Basis for Substantial Equivalence: The ITI® synOcta® angled abutment is claimed to be "substantially equivalent in intended use, material and design" to the listed predicate devices. The FDA concurred with this finding, allowing the device to be marketed.
Note: The provided document is a 510(k) summary, which is a premarket notification for demonstrating substantial equivalence. It does not typically contain detailed clinical study data with acceptance criteria as would be found in a Premarket Approval (PMA) application or a clinical trial report for an AI/ML device.
§ 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.
