Intended Use

Geistlich Fibro-Gide® is intended for soft tissue augmentation. It is indicated for:

  • Localized gingival augmentation to increase keratinized tissue (KT) around teeth and implants A
  • Alveolar ridge reconstruction for prosthetic treatment A
  • Recession defects for root coverage A
Device Description

Geistlich Fibro-Gide® is a fully resorbable, porous, collagen matrix of porcine origin of a spongious consistency. The collagen is extracted from veterinary certified pigs and is carefully purified to avoid antigenic reactions. The collagen scaffold is weakly crosslinked. Geistlich Fibro-Gide® is sterilized in double packaging by Gamma-irradiation.

Geistlich Fibro-Gide® is an implantable device intended for use in soft tissue augmentation procedures. As described in more detail below, the device is indicated specifically for insufficient tissue volume at the alveolar ridge and for soft tissue recession. It has mechanical properties appropriate to withstand the mechanical stresses that occur after wound closure in soft tissue augmentation procedures, i.e., it has good volume stability and it withstands early resorption to allow the formation of new soft tissue and degrades over time. In addition, the matrix is designed with an appropriate thickness to provide sufficient space for the ingrowth of new soft tissue. Due to its good wettability, suturability and biological properties, the device becomes well integrated into the surrounding soft tissue.

AI/ML Overview

The provided text describes a 510(k) premarket notification for a medical device called Geistlich Fibro-Gide®. This document focuses on demonstrating substantial equivalence to a predicate device (Geistlich Mucograft®) rather than establishing novel safety and effectiveness criteria. Therefore, the information provided does not contain traditional "acceptance criteria" for a new device's absolute performance against a set standard, but rather criteria for demonstrating similarity to an already approved device.

Here's an analysis based on the categories you provided:

1. A table of acceptance criteria and the reported device performance:

Since this is a substantial equivalence submission, "acceptance criteria" are implicitly defined by the characteristics of the predicate device. The performance shown is a comparison to that predicate.

The "performance" is that it "passes" these comparative tests.


2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective):

  • Bench Testing: No specific sample sizes are provided for the bench tests. The data provenance is not explicitly stated as country of origin, but the sponsor and manufacturing/sterilization locations are in Switzerland. The testing is assumed to be prospective, undertaken for this submission.
  • Biocompatibility Testing: The specific sample sizes for each biocompatibility test (e.g., number of L929 fibroblast cultures, rabbits, guinea pigs, mice, rats) are not explicitly stated in this summary. The tests adhere to ISO 10993 standards, suggesting standard methods and sample sizes for these types of studies. The provenance of these animal studies is generally considered prospective, conducted for regulatory submission.
  • Animal Studies (Rat and Dog): "a rat and in a dog study" – exact number of animals is not provided. These were conducted "compliant with 21 CFR Part 58" (Good Laboratory Practice for Nonclinical Laboratory Studies), indicating prospective and controlled studies. The country is not specified, but given the sponsor and manufacturing locations, it is likely Europe (Switzerland) or a contracted lab.
  • Clinical Data: "The clinical data from a controlled, parallel and randomized study in patients presenting insufficient soft tissue volume." The sample size (number of patients) is not provided. This describes a prospective study design. The country of origin for the clinical data is not specified.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience):

This document does not describe the establishment of a "ground truth" by experts in the context of diagnostic accuracy, which is common for AI/imaging devices. Instead, the ground truth for this medical device is:

  • Bench testing: Established by laboratory measurements and adherence to scientific standards.
  • Biocompatibility: Established by adherence to ISO 10993 standards and generally accepted biological endpoints.
  • Animal studies: Established by histological examination, physiological measurements, and comparison to the predicate, likely reviewed by veterinary pathologists or relevant scientists.
  • Clinical study: The "ground truth" for safety and effectiveness is derived from the clinical outcomes of the study itself, assessed by the investigators and clinicians involved in the trial.

There is no mention of a panel of experts specifically establishing a "ground truth" for the test sets in the way an imaging device might rely on expert consensus.


4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:

No adjudication method for disagreements among experts is described, as the studies primarily involve objective measurements (benchmarks, lab results) or clinical trial outcomes rather than subjective interpretations requiring adjudication.


5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

Not applicable. This device is a collagen matrix for soft tissue augmentation, not an imaging or diagnostic AI device. Therefore, MRMC studies and "human readers improve with AI vs without AI assistance" are irrelevant to this submission.


6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

Not applicable. This device is a physical implantable medical device, not an algorithm or AI.


7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE

Geistlich Fibro-Gide® and its primary predicate device Geistlich Mucograft® are implantable, collagen matrices (scaffolds) used in dental soft tissue augmentation procedures. Both devices consist of collagen fibers in a loose, porous arrangement to enable cell invasion and settlement, providing an environment to allow for soft tissue growth by using the patient's own healing capacities. Both devices are fully resorbable and do not require a second intervention for removal. Like its reference device, Geistlich Fibro-Gide® is cross-linked. The device dimensions are similar and both devices require adaptation to fit the defect size.

Bench testing was conducted to compare Geistlich Fibro-Gide® against its predicate device in terms of its appearance, porosity, amino acid and protein composition, capillarity and wettability, as well as trimming, suturing and degradation capabilities.

Geistlich Fibro-Gide® was tested in a rat and in a dog study compliant with 21 CFR Part 58 to demonstrate substantial equivalence, safety and performance to its predicate device. The studies confirmed tissue integration, continuous resorption and comparable degradation rate of Geistlich Fibro-Gide® and the predicate devices. Further, the investigation of distal organs, hematologic parameters and clinical chemistries confirmed that the safety profile is acceptable. The dog study also investigated soft tissue augmentation and local tissue effects after several soft tissue augmentation periods in Geistlich Fibro-Gide® and the predicate device Geistlich Mucograft®. In all instances, the subject device was demonstrated to be substantially equivalent to the predicate device.

The clinical data from a controlled, parallel and randomized study in patients presenting insufficient soft tissue volume demonstrated product safety and effectiveness in the product's indications for use.

The biocompatibility testing, in combination with the bench testing, animal studies, and published clinical data included in this submission, demonstrates the substantial equivalence of Geistlich Fibro-Gide® to its predicate device, Geistlich Mucograft®.

CONCLUSION

Based on the data provided within this 510(k) submission as summarized above, it can be concluded that Geistlich Fibro-Gide® is substantially equivalent to the predicate device Geistlich Mucograft® with regard to intended use and indications for use, technological characteristics, including principles of operation, and performance characteristics as shown in a series of biocompatibility, bench, animal, and clinical testing. Thus, the subject device is substantially equivalent.
