Intended Use
Intra Oral Sensor (model: IOX 1 / IOX 2) is intended to collect dental x-ray photons and convert them into electronic impulses that may be stored, views and manipulated for diagnostic use by dentists.
Device Description
Intraoral Sensor (model: IOX 1 / IOX 2) by Dentium is a medical device that acquires digital images by detecting subject information through X-rays and converting them into electrical image signals to identify teeth and tissues in the mouth. The product consists of the Intraoral Sensor, USB Memory, Sensor Holder, Silicon Cover and Quick Guide.
More Information

No
The summary describes a standard digital X-ray sensor and its performance characteristics, with no mention of AI or ML for image processing or analysis.

No.
The device is strictly for diagnostic purposes ("for diagnostic use by dentists") and does not provide any treatment or therapy.

Yes
The "Intended Use" explicitly states that the electronic impulses are "stored, views and manipulated for diagnostic use by dentists." The device acquires digital images of teeth and tissues in the mouth to aid in diagnosis.

No

The device description explicitly lists hardware components (Intraoral Sensor, USB Memory, Sensor Holder, Silicon Cover) and the performance studies focus on hardware characteristics like MTF and DQE of the detector.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are tests performed on samples such as blood, urine, or tissue that have been taken from the human body to detect diseases or other conditions.
  • Device Function: The description clearly states that the device "collect[s] dental x-ray photons and convert[s] them into electronic impulses" to create images of "teeth and tissues in the mouth." This is an imaging device that works directly on the patient's body using external energy (x-rays).
  • No Sample Analysis: There is no mention of analyzing biological samples taken from the patient.

Therefore, the Intra Oral Sensor (model: IOX 1 / IOX 2) is a medical imaging device, not an In Vitro Diagnostic device.

Statement of Substantial Equivalence

5

The intended use, constructions, construction materials, technical characteristics and safety characteristics between Intra Oral Sensor (model: IOX 1 / IOX 2) and its predicate device are same.

The differences include the digital X-ray imager sizes and image viewing software. Performance testing was conducted for the subject device to access whether or not the parameter required for functionalities related to imaging properties of the dental X-ray device meets the designated acceptance criteria. All test results were satisfactory.

Safetv and Effectiveness Information:

Electrical, mechanical and environmental safety testing according to standard of IEC 60601-1(2005+ CORR.1(2006)+CORR.2(2007), AMD 1: 2012 was performed. EMC testing was conducted in accordance with the standard IEC 60601-1-2(2014).

The software of Intra Oral Sensor (model: IOX 1 / IOX 2) has been validated according to FDA "Guidance for the Content d Premarket Submissions for Software Contained in Medical Devices" and applicable requirements contained in the guidance document.

Bench testing was conducted according to FDA Guidance "Format for Traditional and Abbreviated 510(k)s, section 18, Performance Testing - Bench"

Bench testing is used to assess whether or not the parameter measured required for describing functionalities related to imaging properties of the dental X-ray device and patient dosage satisfies the designated tolerance.

Performance (Imaging performance) testing was conducted according to standard of IEC 61223-3-4. All test results were satisfactory.

Non-clinical considerations were conducted in accordance with FDA Guidance for the submissions of 510(k)'s for Solid State X-ray Imaging Devices".

All test results were satisfactory.

The tests include the MTF(Modulation Transfer Function) and DOE(Detective Quantum Efficiency) of detector. MTF of detector shows the resolution more than 30 % at 6 lp/mm and The DQE of detector shows the resolution more than 40 % at 2.5 lp/mm.

Base on the Non-Clinical Test report, Even though the pixel size and active area of predicate detectors are different, the diagnostic image quality of Intra Oral Sensor (model: IOX 1 / IOX 2) is substantially equivalent to that of predicate device and there is no significant difference in efficiency and safety.

Clinical Data: Not required for a finding of substantial equivalence.

Conclusions

In accordance with the federal Food, Drug and Cosmetic Act, 21 CFR Part 807 and based on the information provided in this premarket notification. Dentium Co., Ltd concludes that the Intra Oral Sensor (model: IOX 1 / IOX 2) present no new risk and perform its intended use substantially equivalent to the predicate device.
