(338 days)
The Zeramex® P6 Dental Implant System is intended to be surgically placed in the bone of the upper and lower jaw to provide support for prosthetic devices, such as artificial teeth, in order to restore aesthetics and chewing function.
The Zeramex® P6 Dental Implant System can be used for single or multiple unit restorations.
The Zeramex® P6 implants are intended for delayed loading.
The Zeramex® P6 implants are specially indicated for patients with metal allergies/ intolerances and chronic illness due to metal allergies/intolerances.
The Zeramex® P6 (Ø3.3mm SN) implant may only be used in the anterior teeth in the lower jaw and lateral teeth in the upper jaw.
The Zeramex® P6 Dental Implant System is an endosseous dental implant/abutment system including various sizes of endosseous two piece dental implants, abutments, and accessories. The Zeramex® P6 implants may be restored with cement retained abutments or screw retained abutments, depending on the dentist's preference. The Zeramex® P6 implants are placed using the Zeramex® P6 surgical tools.
The implants, produced from aluminum toughened zirconia, are provided in three diameters (Ø 3.3 mm. 4.1 mm. and 4.8 mm),three lengths (8 mm, 10 mm, and 12 mm). The implants are designed with an internal cylindrical connection. Anti-rotational features include internal triangular designs and external hexagonal connections; the feature used depends on the restoration method selected.
Straight and angular (15°) cement retained and screw retained abutments, provided in small neck (SN: 4.0mm) and regular neck (RN. 4.8mm) sizes, are compatible for use with the Zeramex® P6 implants. The straight and angular abutments are made from the same zirconium materials as the Zeramex® P6 implants.
The cement retained Zeramex® Zeralock™ straight and angular abutments have a cylindrical connector which fits into the internal cylindrical connection of the implant and a hexagonal design which fits into the implant's internal triangular design and locks the abutment into place. This design mitigates rotation in six possible positions.
The screw retained Zeramex® P6 abutments fit on the implant's external hexagonal connection such that rotation is mitigated in six possible positions. The Zeramex® P6 screw retained abutments are affixed to the implant with a carbon fiber reinforced PEEK-Optima™ Ultra (Endolign) screw which fits the internal thread of the implant and provides a secure, screw retained ceramic on ceramic connection.
Locator abutments facilitate removable full restoration of the upper or lower jaw. Three sizes (heights 2/3/5 mm) for each platform (SN 4.0mm and RN 4.8mm) are provided for the Zeramex® P6 Dental Implant System and provide the Zeralock™ connection. The Zeramex® P6 Locators are made from ATZ.
The Zeramex® Zeralock™ cement retained abutments are bonded to the implants using dental cements which have been tested and validated for use with the Zeramex® systems: Panavia" (K032455) and 3M ESPE RelyX (K111185).
The screw retained abutments are attached to the implants using carbon-fiber reinforced (CFR) PEEK-Optima™ Ultra (Endolign) screws (provided as straight and angular screws in SN and RN sizes).
Healing caps and gingiva formers are also provided in the system. These components, provided in SN and RN sizes, are manufactured from PEEK and are connected to the implant using a screw. The Zeramex® P6 Gingiva formers are provided in two (2) lengths (3 mm and 4 mm). Provisional restoration components may be used to support temporary crowns after the healing period. The Zeramex® P6 Provisional Restoration SN and RN are made of PEEK. The Zeramex® P6 Provisional Restoration Screw is made of carbon fiber reinforced PEEK.
Here's an analysis of the provided text regarding the acceptance criteria and supporting studies for the Zeramex® P6 Dental Implant System:
1. Table of Acceptance Criteria and Reported Device Performance
The provided FDA 510(k) summary does not explicitly state pre-defined acceptance criteria (e.g., a specific percentage for success rates or a certain threshold for complications). Instead, it describes a retrospective clinical study and non-clinical tests whose positive results support the substantial equivalence claim.
However, based on the non-clinical and clinical study outcomes, we can infer the implied acceptance criteria from the reported success:
| Acceptance Criteria (Inferred) | Reported Device Performance |
|---|---|
| Non-Clinical: | |
| Cleaning and Sterilization Validation (ISO 17665-1, ISO 17665-2, ISO 11737-1, ISO 11737-2) | Device met standards (implied by positive review). |
| Shelf-life, Packaging, and Transport Validation (ASTM F1980, ASTM F88, ASTM F1886, ASTM F1929, ISO 11607-1, ISO 11607-2) | Device met standards (implied by positive review). |
| Biocompatibility (ISO 10993-5) | Device met standards (implied by positive review). |
| Surface Chemical & Roughness Analysis (XPS, SEM, Contact Angle) | Analysis performed; results support design (implied by positive review). |
| Fatigue Testing (ISO 14801, for new and aged samples) | Device met standards (implied by positive review). |
| Clinical: | |
| Absence of Post-operative Complications (e.g., anesthesia, paresthesia, mandibular fracture, alveolar ridge height loss, adverse impact on adjacent teeth, abnormal/prolonged pain, fistula, infection, osteomyelitis) | No complications reported at implant placement, loading, and follow-up (up to >1 year). |
| Absence of Adverse Reactions (e.g., infection, pain, altered sensation, TMJ problems, implant loss, implant breakage, abutment breakage) | No adverse reactions reported at implant placement, loading, and follow-up (up to >1 year). |
| Absence of Screw Issues (movement, fracture, replacement) | No reports of screw movement, fracture, or replacement. |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size (Clinical Test Set): 19 patients, receiving a total of 35 screw-retained abutments. Follow-up data was obtained on 15 of those patients (representing 27 screw-retained abutments). Specific follow-up numbers are:
-
6 months follow-up: 8 patients
-
1 year follow-up: 3 patients
-
- Data Provenance: Retrospective clinical data. The country of origin is not explicitly stated in the provided text.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
The document does not specify the number or qualifications of experts used to establish a "ground truth" for the retrospective clinical test set. The data appears to rely on clinical observations and professional documentation from the treatment of the 19 patients. It's implied that the treating clinicians (dentists/surgeons) made the assessments of complications and adverse events.
4. Adjudication Method for the Test Set
The document does not describe any specific adjudication method (e.g., 2+1, 3+1, none) for the clinical test set data. Given it's retrospective clinical data, it's highly likely that the outcomes were recorded as part of routine patient care, without a formalized independent adjudication process mentioned for the purpose of this 510(k) submission. Therefore, the adjudication method is effectively "none" in the context of this regulatory submission.
5. If a Multi-Reader, Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No, a multi-reader, multi-case (MRMC) comparative effectiveness study was not done. This study focuses on the safety and performance of the device itself, not on comparing differences in human reader performance with or without AI assistance, as the device is a dental implant system, not an AI diagnostic tool.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
This question is not applicable. The Zeramex® P6 Dental Implant System is a physical medical device (dental implant and associated components), not an algorithm or software-as-a-medical-device (SaMD). Therefore, "standalone algorithm performance" is not relevant to this submission.
7. The Type of Ground Truth Used
For the clinical study, the "ground truth" was based on clinical observations and outcomes data from real patients. This includes:
- Absence of complications (e.g., infection, pain, fracture).
- Absence of adverse events.
- Stability and function of the implant and abutment over time.
For the non-clinical studies, the "ground truth" was established by adherence to recognized international and national standards (e.g., ISO, ASTM) for material properties testing, biocompatibility, sterilization validation, and fatigue strength.
8. The Sample Size for the Training Set
The document does not describe a "training set" in the context of machine learning or AI. This is a traditional medical device submission, not an AI/ML device. Therefore, this question is not applicable.
9. How the Ground Truth for the Training Set Was Established
As there is no training set mentioned or implied for an AI/ML device, this question is not applicable.

Discussion
There is only a slight difference between the indications for use statement of the Zeramex® P6 Dental Implant System and the Zeramex® T Dental Implant System which is the addition of the term "intolerances". The addition of patients with metal intolerances to the previous indication for patients with metal allergies does not change the intended use of the device for patients for which traditional titanium implant systems may not be appropriate.
The ZERAMEX® P6 Implants feature the same material, same connection concept (internal cylinder with triangular anti-rotation feature), same surface treatment, and similar abutments as the previously cleared ZERAMEX® T system for cemented abutments.
{9}------------------------------------------------
As seen above, the differences between the subject and primary predicate is the provision of screw retained abutments, addition of an external hexagon anti-rotation feature for the screw-retained abutments, the inclusion of a carbon-fiber reinforced PEEK abutment fixation screw, and the reduction of the implant body diameter from 3.5 to 3.3mm.
The implants are similar in shape and diameter as the previously cleared Straumann® Implants. The ZERAMEX® P6 Implants additionally feature an external hexagon connection similar to the previously cleared Branemark Implants.
The connecting abutment features a fitting hexagon and is of same material as the previously cleared Procera® Abutment.
Performance Data VII.
The following performance data were provided in support of the substantial equivalence determination.
Non-Clinical Studies
- . Cleaning and Sterilization Validation according to ISO 17665-1, ISO 17665-2. ISO 11737-1 and ISO 11737-2.
- Shelf-life, Packaging, and transport validation according to ASTM F1980, ASTM ● F88. ASTM F1886. ASTM F1929, ISO 11607-1, and ISO 11607-2.
- . Biocompatibility in accordance with ISO 10993-5
- Surface chemical and roughness analysis by XPS. SEM, and contact angle .
- . Fatigue testing in accordance with ISO 14801 for new as well as artificially aged samples of the submission device
Clinical Studies
Retrospective clinical data on implants and prosthetics was obtained on 19 patients who received a total of 35 screw retained abutments. Follow up data was obtained on 15 of those patients (representing 27 screw retained abutments), with > 6 month follow up data on eight (8) patients, and > 1 year follow up data on three (3) patients.
Patients were between the ages of 36 and 69 years old, with no local risk factors. Implants were placed in the maxilla and mandible using a 2-step loading process with the time to loading ranging from 12 to 24 weeks.
Bone quantity ranged very heavy bone to soft bone, with all patients presenting with good bone quality.
{10}------------------------------------------------
No post-operative complications or adverse events were reported for any of the patients at the implant placement and loading phases. Follow up data (n = 15 patients, 27 implants/abutments) shows that there were no post-operative complications defined as anesthesia or paresthesia, mandibular fracture, loss of alveolar ridge height, adverse impact on adjacent teeth, abnormal or prolonged pain, failure to maintain adequate oral hygiene, fistula, infection, or osteomyelitis. No adverse reactions (infection, pain, altered sensation, temporomandibular joint problems, implant loss prior to loading, loss of loaded implant, implant breakage, or abutment breakage) were reported. In addition, there were no reports of screw movement, fracture, or replacement.
Conclusion
Although differences in design and technology exist between the subject and predicate devices, these differences are supported by the biocompatibility, fatigue, and retrospective clinical study data described above. Therefore, it is concluded that the Zeramex® P6 Dental Implant System is substantially equivalent to the predicate devices.
