The ARCHITEX™ Space Maintenance System is indicated for use as temporary implants to stabilize and support autograft, autograft extenders, allograft, and bone void fillers and/or fractured bone segments with or without bone plates or ritanium mesh in bony defects of oral maxillofacial anatomy.

Device Description

ARCHITEX™ Space Maintenance System is intended for use in oral-maxillofacial surgical reconstruction and dental regeneration procedures; the implants contained in the System are for maintaining space during bone grating procedures and/or to support soft tissue until bone formation.

The ARCHITEX™ Space Maintenance System consists of a variety of shapes and sizes of screws (Socket Preservation, Tenting, and Mesh Fixation Screws) and titanium mesh implants components as well as placement instruments components. These instruments supplied are general class I instruments added as a convenience for doctors to use to place the provided implants.

The ARCHITEX™ Space Maintenance System includes a selection of Socket Preservation screws which are designed to aid in extraction socket grafting while simultaneously supporting the original gingival margins and papilla.

The ARCHITEX™ Space Maintenance System components are fabricated from medical grade stainless steel and medical grade titanium or titanium alloy. Medical grade titanium and titanium alloy may be used together. The subject implants components will be manufactured from medical grade titanium allov described by such standards as ASTM F 136-08el or ISO 5832-3, and/or from medical grade unalloyed titanium described by such standard as ASTM F67-06. The placement instruments components will be manufactured from medical grade stainless steel as described in ASTM F8PP-09. The ARCHITEX™ Space Maintenance System is sold non-sterile.

The purpose of this 510(k) application is to seek marketing clearance for the ARCHITEX™ Space Maintenance System to be used as a root-form endosseous dental implants system.

2. Sample Size Used for the Test Set and Data Provenance

The document does not explicitly state the sample size for the test set. However, the non-clinical tests involved "Subject Devices and Predicate Devices" to compare their performance. The data provenance is not specified, but these are primarily bench performance tests conducted on the physical devices rather than patient data.

3. Number of Experts Used to Establish Ground Truth and Qualifications

This information is not applicable. The study involved non-clinical bench testing and material/dimensional analysis, not clinical ground truth established by experts.

4. Adjudication Method

This information is not applicable, as the study did not involve expert adjudication of clinical data.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. The study focused on the physical and mechanical properties of the device and its predicates.

6. Standalone (Algorithm Only) Performance

No, a standalone (algorithm only) performance study was not done. This device is a physical implant system, not a software algorithm.

7. Type of Ground Truth Used

The "ground truth" for this submission was established through:

Dimensional and Material Analysis: Comparing the physical specifications and materials of the ARCHITEX™ components against the predicate devices.
Bench Performance Testing: Conducting standardized and non-standardized mechanical tests (Static Axial Pullout, Static Subsidence, Static Cantilever Bending, Static "Removal Torque" and "Torque to Failure") on both the subject and predicate devices. The results of these tests served as the empirical "ground truth" for equivalence claims.

8. Sample Size for the Training Set

This is not applicable, as there was no "training set" in the context of an algorithm. The study compared the device components directly to predicate device components through bench testing.

9. How the Ground Truth for the Training Set Was Established

This is not applicable, as there was no "training set" for an algorithm. The "ground truth" for the non-clinical evaluation was established through direct comparison of material properties, dimensions, and mechanical performance between the ARCHITEX™ System components and the legally marketed predicate devices, using established ASTM standards where available, and conducting comparative testing where industry standards were absent.

VI. Brief Discussion of the Non-Clinical Tests Submitted

For a determination of substantial equivalence, the following analysis and bench performance tests were performed on Subject Devices and Predicate Devices:

Analysis of Dimensional and Material Features
·> Statis Axial Pullout Testing in accordance with ASTM F543-02

{2}------------------------------------------------

Statis Subsidence Testing (To date there is no industry standards)
Statis Cantilever Bending Testing (To date there is no industry standards)
Static "Removal Torque" and "Torque to Failure" testing in accordance with ASTM F543-02

VII. Conclusions Drawn from the Non-Clinical Tests

Results of material and dimensional analysis have demonstrated that ARCHITEX™ Space Maintenance System implants are equivalent to the predicate devices in terms of bone/screw interface features.

When compared with predicate devices, results of bench performance testing indicated all acceptance criteria were met, and demonstrated the subject Tenting Screws and Socket Preservation Screws have equivalent static axial pullout and subsidence strength and that the subject Titanium Mesh has equivalent static cantilever bending strength.

The conclusions drawn from the analysis and performance testing, along with the intended use of the subject devices demonstrate that the ARCHITEX™ Space Maintenance System is substantially equivalent to the listed predicate devices.
