Meta G UCLA Abutment is intended for use with a dental implant to provide support for prosthetic restorations such as crowns, bridges, or overdentures.

The Meta G UCLA Abutment is used for prosthetic restoration. The Meta G UCLA Abutment consists of Meta G UCLA Abutment and abutment screws. The Meta G UCLA Abutment is made of CCM (ASTM F1537) and POM (ASTM F1855). The casting material to make prosthesis is also CCM. When cast a prosthesis with the Meta G UCLA Abutment, the post height above the transmucosal collar of the Meta G UCLA Abutment has to be taller than 4mm and maximum 7mm.

The Meta G UCLA Abutment has Hex, Non Hex connection. Hex-type abutment should be used for single unit restorations and is not recommended for multiple tooth restorations. Non Hex-type abutment is for multiunit restorations only. No angulation is to be incorporated into the cast final device and abutments should not be used on implants placed at an angle.

It is provided non-sterile, this should be user steam sterilized before use. The Meta G UCLA abutment is compatible with our own implant system.

The provided document is a 510(k) summary for a medical device (Meta G UCLA Abutment) seeking clearance from the FDA. It does not describe a study proving the device meets acceptance criteria for an AI/ML powered device. Instead, it details the device's technical specifications, indications for use, and a comparison to predicate devices to demonstrate "substantial equivalence."

Therefore, I cannot fulfill your request for information on acceptance criteria and a study proving an AI/ML device meets them, as this document is not about an AI/ML device or its performance evaluation in that context. This document focuses on the mechanical and material properties of a dental abutment and its equivalence to previously cleared devices.

Here's why and what information is available (though not directly answering your prompt):

• Type of Device: The Meta G UCLA Abutment is an "Endosseous Dental Implant Abutment." This is a mechanical medical device, not an AI/ML powered one.
• Performance Data (Non-Clinical) - Section 7: This section outlines the tests performed to demonstrate the safety and equivalence of the mechanical device:
  • Sterilization validation testing: In accordance with ISO 17665-1 and ISO 17665-2 for steam sterilization.
  • Biocompatibility testing: In accordance with ISO 10993-3, 5, 10, 11.
  • Biocompatibility of the abutment screw: Leveraged from a previously cleared submission (K201323).
  • MR Environment Condition: A non-clinical worst-case MRI review was performed using scientific rationale and published literature to assess magnetically induced displacement force and torque.

These are standard regulatory requirements for this type of mechanical implant component, not acceptance criteria for an AI/ML algorithm's analytical performance (e.g., sensitivity, specificity, AUC).

If you have a document pertaining to an AI/ML powered device, I would be happy to analyze it according to your requested criteria.
