OSSTEM CO., LTD.
AVANA Dental Implant Systems are designed for use in dental implant surgery. A successfully osseointegrated implant will achieve a firm and direct connection between the living bone and the surface of the titanium fixture when surgically implanted under controlled conditions, as per well known clinical studies. They are intended for use in partially or fully edentulous mandibles and maxillae, in support of single or multiple-unit restorations including; cement retained, screw retained, or overdenture restorations, and terminal or intermediate abutment support for fixed bridgework.
The Avana SS-II Implant is a threaded, root form endosseous implant comprised of an internal octa, one-stage 8° morse tapered device manufactured from commercially pure titanium. The implant's external threaded surfaces are roughened to facilitate tissue and bone integration. The implant's self-tapping feature may be used with or without pre-tapping the bone. System components for restorative purposes include: screw-on and cemented abutments, healing abutments, and angled abutments. Surgical accessories include drills, depth gages, drivers, torque wrenches, taps, reamers and fixture mount removal tool.

2. Sample Size and Data Provenance
The provided text does not specify the exact sample sizes used for the biocompatibility animal studies or the in-vitro performance tests. It also does not specify the data provenance (e.g., country of origin of the data, retrospective or prospective).
3. Number of Experts and Qualifications for Ground Truth
The provided information does not indicate the number of experts used to establish ground truth for any specific test set, nor does it state their qualifications. The studies mentioned (biocompatibility, animal studies, in-vitro performance) are laboratory or animal model-based, not involving human expert interpretation of data in the way a clinical diagnostic device might.
4. Adjudication Method
The provided information does not describe any adjudication method as it pertains to human interpretation of data. The types of studies cited (biocompatibility, animal, in-vitro) do not typically involve human adjudication in the context of establishing ground truth for a test set.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No MRMC comparative effectiveness study was mentioned or performed. This device is an endosseous implant, a physical medical device, not a diagnostic imaging or AI-assisted system that typically undergoes MRMC studies to evaluate human reader improvement.
6. Standalone (Algorithm Only) Performance Study
No standalone performance study (i.e., algorithm only without human-in-the-loop performance) was done. This is not an algorithmic or AI device.
7. Type of Ground Truth Used
The ground truth for this device is based on:
- Established standards and methodologies: For biocompatibility, it's ISO 10993-1.
- Biological responses: For surface treatment performance, it's likely based on physiological reactions in animal models.
- Engineering and material science measurements: For device durability and material characterization, it's based on objective physical measurements from laboratory tests (e.g., compression, fatigue, spectroscopy).
8. Sample Size for Training Set
This device is a physical medical implant, not a machine learning model, therefore, there is no concept of a "training set" as understood in the context of AI or algorithms.
9. How Ground Truth for Training Set Was Established
As there is no training set for this type of device, this question is not applicable.
