The summary describes a physical dental implant system and does not mention any software, algorithms, or AI/ML capabilities.
Yes
The device is a dental implant system used for oral rehabilitation of edentulous and partially dentate patients, which is a therapeutic intervention to restore function and aesthetics.
No
The provided text describes the PUR Implant System, which is a dental implant system used for oral rehabilitation. It is a physical device intended for implantation, not for diagnosing conditions or diseases.
No
The device description clearly details a physical dental implant system made of titanium, including implants, abutments, and a driver. There is no mention of software as a component of this system.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Definition of IVD: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Description: The description clearly states that the PUR Implant System is a dental implant used for oral rehabilitation. It is a physical device implanted into the jawbone.
- Intended Use: The intended use is for dental implant applications, including supporting crowns, bridges, and dentures. This is a surgical and prosthetic application, not a diagnostic test performed on a sample.
- Lack of IVD Characteristics: The text does not mention any analysis of biological samples, detection of biomarkers, or diagnostic purposes.
Therefore, the PUR Implant System is a medical device, specifically a dental implant, but it does not fit the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
The PUR Implant System can be used in dental implant applications, for oral rehabilitation of edentulous and partially dentate patients in the maxilla and mandible. Implant retained restorations may consist of single crowns or bridges as well as complete or partial dentures. The Pur Implant is intended for delayed loading. It is also indicated for immediate loading with good primary stability and appropriate occlusal loading.
The PUR Implant System is only intended for use with straight abutments. The PUR implant body is intended to be placed such no angle correction is necessary.

Device Description
The PUR is a self-tapping, double thread screw implant with a micro groove section, manufactured from Wrought Titanium 6AL-4V ELI. The implant surface is grit-blasted and acid etched. The implants are manufactured with four body diameters 3.5 mm, 4.3 mm, and 6.0 mm. The 3.5 and 4.3 mm implants have a Narrow Platform (NP) prosthetic head. The 5.0 and 6.0 mm implants have a Regular Platform (RP) prosthetic head. The PUR implants are substantially equivalent to the Zimmer Tapered Screw-Vent® 3.5 mmD Platform and the 4.5 mmD Platform implant systems. They provide for non- rotational single and multiple tooth restorations in both the maxilla and mandible. They are packaged sterile in a double blister, which contains: the implant in a titanium tube. A special driver is available for the implants which simplifies implant insertion by eliminating the need for an implant mount.
This device uses straight abutments with no angles. Sterngold has SA Abutments) which are intended for multi-unit restorations. Sterngold also has UCLA abutments which are twopiece abutments composed of Wrought Titanium 6AL-4V ELI, conforming to ASTM F136-13 and Gold Alloy (64% gold, 22% palladium and 14.0% platinum). These UCLA abutments are intended for single and multiple unit use.
The PUR implant system is not intended to include any angled abutments or allow for any correction of angled implant placement.
The PUR Dental Implant will be available in a range of lengths and diameters.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non clinical Testing was performed following "Guidance for Industry and FDA Staff -Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments." Performance testing demonstrated that the device performs appropriately for the proposed indications for use.
Surface analysis was conducted on the final device. SEM photographs confirm that all residue of blasting material had been removed from the treated implant surface, and the surface chemical analysis confirmed that no contaminants remained on the surface.
PUR Implants have the same sterilization process and radiation dose, same shelf life and biocompatibility as previous cleared Sterngold devices, therefore sterility, shelf life and biocompatibility testing performed on previous cleared Sterngold devices is applicable to the PUR Implants. As a result, the PUR Implant System including abutments is substantial equivalent to its predicates.

Indications for Use:
The PUR Implant System can be used in dental implant applications, for oral rehabilitation of edentulous and partially dentate patients in the maxilla and mandible. Implant retained restorations may consist of single crowns or bridges as well as complete or partial dentures. The PUR Implant is intended for delayed loading. It is also indicated for immediate loading with good primary stability and appropriate occlusal loading.
The PUR Implant System is only intended for use with straight abutments. The PUR implant body is intended to be placed such no angle correction is necessary.
Substantial Equivalence:
The proposed PUR Dental implants are substantially equivalent to other currently marketed dental implant systems that have been cleared by FDA through the 510(k) Premarket Notification process. While the Indications for Use statements are not identical between the subject and referenced predicates, the difference in verbiage does not alter the intended use of the subject device. The subject and reference devices all provide oral rehabilitation of edentulous and partially dentate patients in the maxilla and mandible. Both the subject device and its primary predicate are intended for delayed loading as well as immediate loading when there is good primary stability and an appropriate occlusal load. Therefore, the differences noted between the subject and predicates Indications for Use verbiage do not render the subject device as not substantially equivalent to its referenced predicates. The intended use, basic design, fundamental operating principles, sterilization process, shelf life and bio-compatibility of the subject device are equivalent to the predicate devices.
Technological Characteristics:
The PUR dental Implant provides the same or similar functions as well as design and technological characteristics as its predicate devices. In addition, the subject device is identical to the cleared Sterngold Acid Etched Implant (K023580).
The abutments for the subject device are the same or similar to the predicate devices, in terms of intended use, design and function. The materials, technology and processes used to produce the PUR dental implants and abutments are the same as other Sterngold Dental devices previously cleared by the FDA. Any differences between the proposed devices and its predicates do not affect the substantial equivalence. See the comparison chart below for list of similarities and differences.

Performance Testing:
Non clinical Testing was performed following "Guidance for Industry and FDA Staff -Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments." Performance testing demonstrated that the device performs appropriately for the proposed indications for use.
Surface analysis was conducted on the final device. SEM photographs confirm that all residue of blasting material had been removed from the treated implant surface, and the surface chemical analysis confirmed that no contaminants remained on the surface.
PUR Implants have the same sterilization process and radiation dose, same shelf life and biocompatibility as previous cleared Sterngold devices, therefore sterility, shelf life and biocompatibility testing performed on previous cleared Sterngold devices is applicable to the PUR Implants. As a result, the PUR Implant System including abutments is substantial equivalent to its predicates.
Conclusion:
Based on our analysis, technological characteristics and performance testing, the PUR Implant System is substantially equivalent in intended use, material, design and performance to its predicates.
