Yes
The device is used to facilitate guided bone and tissue regeneration following dental and periodontal procedures, which are therapeutic interventions.
No
The device is a collagen membrane used for guided bone regeneration and tissue regeneration. It is a regenerative material, not a diagnostic tool that detects or measures conditions.
No
The device description clearly states that the device is a "pure collagen membrane with a bilayer structure," indicating it is a physical material, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended uses listed are all related to surgical procedures for bone and tissue regeneration in the mouth. These are therapeutic and reconstructive applications, not diagnostic tests performed on samples taken from the body.
- Device Description: The device is described as a collagen membrane used as a barrier in surgical procedures. This is a physical implant/barrier, not a reagent or instrument used to analyze biological samples for diagnostic purposes.
- Lack of Diagnostic Elements: There is no mention of analyzing samples (blood, tissue, etc.), detecting biomarkers, or providing diagnostic information about a patient's condition.
- Performance Studies: The performance studies described evaluate the device's ability to facilitate bone and tissue regeneration in vivo (in living organisms), not its accuracy in diagnosing a condition.
In summary, the Geistlich Bio-Gide® products are medical devices used in surgical procedures for tissue regeneration, not in vitro diagnostic devices used for testing biological samples.

Device Description
Geistlich Bio-Gide® Shape is a pure collagen membrane with a bilayer structure. The porous surface (facing the bone) allows the ingrowth of bone forming cells into the membrane, and the dense surface (facing the soft tissue) prevents the ingrowth of fibrous connective tissue into the bone defect. The membrane is made of collagen without further cross-linking, and is sterilized by gamma irradiation. The Geistlich Bio-Gide® Shape membrane has a pre-shaped form with a maximum width and height of 14mm x 24mm, respectively. With the exception of the size and shape, Geistlich Bio-Gide® Shape is the same as its predicate device, Geistlich Bio-Gide® Perio (K112575).

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
SUMMARY OF ANIMAL STUDY DATA
An in vivo animal study was conducted to evaluate the performance of Geistlich Bio-Gide® in facilitating guided bone regeneration around exposed implant threads (K960724). The results showed that treatment with Geistlich Bio-Gide® improved the decrease of defect size after 6 months, as evaluated histologically and by histomorphometry.
SUMMARY OF CLINICAL STUDY DATA
The clinical performance of the Geistlich Bio-Gide® family of products has been established based on clinical testing data from the K960724 and K042197 reference devices. A total of 75 patients were recruited in a study to examine the effectiveness and tolerability of Geistlich Bio-Gide® as a barrier membrane for quided bone regeneration in simultaneous implant placement. The results demonstrated the performance of Geistlich Bio-Gide® in combination with Geistlich Bio-Oss for bone regeneration in defects around implants. No serious adverse event or antigenic reaction was observed. Only minor or moderate signs of inflammation, including pain, swelling, redness, hematoma or wound dehiscences were noted and were probably related to the surgical procedure.
Another clinical study involved 15 patients and the application of 16 Geistlich Bio-Gide membranes, which similarly showed that Geistlich Bio-Gide® can be used in defect filling in combination with bone grafting material Geistlich Bio-Oss®.
For Geistlich Bio-Gide® Compressed, additional clinical studies were conducted for guided tissue regeneration procedures in periodontal defects:
- Recession defects: 20 patients, each contributing a pair of Miller Class I or II buccal gingival recessions. Treatment with Geistlich Bio-Gide® resulted in a significant gain of root coverage at 3 months and decrease of recess depth at 6 months.
- Furcation defects:
- A total of 52 grade II mandibular molar furcation defects. The experimental group combined Bio-Oss® and Bio-Gide® presented with significantly greater pocket reduction, gain in clinical attachment level (CAL), vertical defect fill and horizontal defect fill compared to the control group (SCTG).
- 21 patients with 31 furcation defects. There was a statistically significant improvement in most clinical indices for the Bio-Oss®/ Bio-Gide® group.
- Intrabony defects:
- 22 paired intrabony defects. Postoperative pocket depths, attachment levels and transoperative bone measurements were similar for control (open-flap debridement) and experimental (bovine porous bone mineral and Geistlich Bio-Gide®) sites.
- 28 patients suffering from chronic periodontitis, and each of whom displayed one intrabony defect. No differences in any of the investigated parameters at baseline between Bio-Gide® treatment and access flap surgery (AFS). At 1 year after surgery both therapies resulted in significant gains of clinical attachment level (CAL) and probing depth (PD) reductions. The Bio-Gide® treatment group resulted in significantly higher CAL gains than treatment with AFS.
- 124 patients with advanced chronic periodontitis, each with at least one intrabony defect of no less than 3mm. The Bio-Gide® test group showed a significantly higher gain in CAL and pocket reduction compared to the controls.
- 4 intrabony defects, two received Geistlich Bio-Gide® alone and two were treated with a combination of Bio-Oss®/ Bio-Gide®. Both treatments were shown to significantly improve clinical probing depths and attachment levels, and the radiographic appearance suggested osseous fill. The regenerative effect was more pronounced with Bio-Gide®. Histologic evaluation revealed that both treatments produced new cementum with inserting collagen fibers and new bone formation on the surface of the graft particles.
- 4 intrabony defects, two received Geistlich Bio-Gide® alone and two were treated with a combination of Bio-Oss®/ Bio-Gide®. Use of Bio-Oss® in combination with / Bio-Gide® resulted in a complete new attachment apparatus, evidencing periodontal regeneration that varied with defect morphology.

Geistlich Bio-Gide® Compressed is made of the same raw materials and manufactured with the same manufacturing process (except for the cutting step and marking the device with "UP") as the predicate device. Hence, the material properties are identical. Further, the same release testing is conducted for the subject and predicate devices, which includes determination of appearance, dry residue, sulphated ash, nitrogen total content, nitrogen amide content, fat content, pH value, native collagen, amino acid analysis, sterility test and bacterial endotoxins. Lot testing confirmed that Geistlich Bio-Gide® Compressed meets the specification and is equivalent to Geistlich Bio-Gide®. Usability tests confirmed that Geistlich Bio-Gide® Compressed has appropriate handling properties and is easy to use. Sterilization of the subject device is based on the predicate and reference devices Geistlich Bio-Gide® Perio and Geistlich Bio-Gide® conducted according to the standards ISO 11137-1, ISO 11137-2, ISO 11137-3, ISO 11737-1 and ISO 11737-2, which showed that the devices meet the sterility specification. A viral clearance study in accordance with the requirements of ICH Q5A and ISO 22442-3 was conducted and confirmed sufficient viral clearance capacity of the manufacturing process of the Geistlich Bio-Gide® family of products.
The following biological risks were evaluated according to ISO 10993: cytotoxicity (ISO 10993-5), genotoxicity (ISO 10993-3), carcinogenicity (ISO 10993-3), irritation (ISO 10993-10), sensitization (ISO 10993-10), acute toxicity (ISO 10993-11), subchronic and chronic toxicity (ISO
11
10993-11) and implantation (local effects; ISO 10993-6). The results demonstrated that the device is biocompatible.
SUMMARY OF ANIMAL STUDY DATA
An in vivo animal study was conducted to evaluate the performance of Geistlich Bio-Gide® in facilitating guided bone regeneration around exposed implant threads (K960724). The results showed that treatment with Geistlich Bio-Gide® improved the decrease of defect size after 6 months, as evaluated histologically and by histomorphometry.
SUMMARY OF CLINICAL STUDY DATA
The clinical performance of the Geistlich Bio-Gide® family of products has been established based on clinical testing data from the K960724 and K042197 reference devices. A total of 75 patients were recruited in a study to examine the effectiveness and tolerability of Geistlich Bio-Gide® as a barrier membrane for guided bone regeneration in simultaneous implant placement. The results demonstrated the performance of Geistlich Bio-Gide® in combination with Geistlich Bio-Oss for bone regeneration in defects around implants. No serious adverse event or antigenic reaction was observed. Only minor or moderate signs of inflammation, including pain, swelling, redness, hematoma or wound dehiscences were noted and were probably related to the surgical procedure.
Another clinical study involved 15 patients and the application of 16 Geistlich Bio-Gide membranes, which similarly showed that Geistlich Bio-Gide® can be used in defect filling in combination with bone grafting material Geistlich Bio-Oss®.
In addition, the performance of Geistlich Bio-Gide® in guided tissue regeneration procedures in periodontal defects was evaluated in several clinical studies, as summarized below:
| Defect Type | Subjects | Key Findings |
|---|---|---|
| Recession | ||
| defects | 20 patients, each contributing a | |
| pair of Miller Class I or II buccal | ||
| gingival recessions | Treatment with Geistlich Bio-Gide® resulted in a | |
| significant gain of root coverage at 3 months and | ||
| decrease of recess depth at 6 months. | ||
| Furcation | ||
| defects | A total of 52 grade II mandibular | |
| molar furcation defects | The experimental group combined Bio-Oss® and | |
| Bio-Gide® presented with significantly greater | ||
| pocket reduction, gain in clinical attachment level | ||
| (CAL), vertical defect fill and horizontal defect fill | ||
| compared to the control group (SCTG). | ||
| 21 patients with 31 furcation | ||
| defects | There was a statistically significant improvement in | |
| most clinical indices for the Bio-Oss®/ Bio-Gide® | ||
| group. |
12
| Intrabony
defects | 22 paired intrabony defects | Postoperative pocket depths, attachment levels and
transoperative bone measurements were similar for
control (open-flap debridement) and experimental
(bovine porous bone mineral and Geistlich Bio-
Gide®) sites. |
|----------------------|-----------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| | 28 patients suffering from
chronic periodontitis, and each
of whom displayed one
intrabony defect | No differences in any of the investigated parameters
at baseline between Bio-Gide® treatment and
access flap surgery (AFS). At 1 year after surgery
both therapies resulted in significant gains of clinical
attachment level (CAL) and probing depth (PD)
reductions. The Bio-Gide® treatment group resulted
in significantly higher CAL gains than treatment with
AFS. |
| | 124 patients with advanced
chronic periodontitis, each with
at least one intrabony defect of
no less than 3mm | The Bio-Gide® test group showed a significantly
higher gain in CAL and pocket reduction compared
to the controls. |
| | 4 intrabony defects, two
received Geistlich Bio-Gide®
alone and two were treated with
a combination of Bio-Oss®/ Bio-
Gide® | Both treatments were shown to significantly improve
clinical probing depths and attachment levels, and
the radiographic appearance suggested osseous fill.
The regenerative effect was more pronounced with
Bio-Gide®. Histologic evaluation revealed that both
treatments produced new cementum with inserting
collagen fibers and new bone formation on the
surface of the graft particles. |
| | 4 intrabony defects, two
received Geistlich Bio-Gide®
alone and two were treated with
a combination of Bio-Oss®/ Bio-
Gide® | Use of Bio-Oss® in combination with / Bio-Gide®
resulted in a complete new attachment apparatus,
evidencing periodontal regeneration that varied with
defect morphology. |
The above studies also showed a favorable safety profile for Geistlich Bio-Gide®, with no serious adverse events noted.
CONCLUSION
In summary, Geistlich Bio-Gide® Compressed has the same indications and identical material properties as the predicate device, Geistlich Bio-Gide® Perio. The sizes of Geistlich Bio-Gide® Compressed have been modified and a marking step is included during manufacture, but these differences are minor and do not affect the performance of the device, as supported by the testing conducted.
Based on the data provided within this 510(k) submission as summarized above, it can be concluded that Geistlich Bio-Gide® Compressed is substantially equivalent to the Geistlich Bio-Gide® Perio, the predicate device.
