Intended Use
Geistlich Bio-Gide® is intended for the following uses: - · augmentation around implants placed in immediate extraction sockets; - · augmentation around implants placed in delayed extraction sockets; - · localized ridge augmentation for later implantation; - · alveolar ridge reconstruction for prosthetic treatment; - · filling of bone defects after root resection, cystectomy, removal of retained teeth; - · guided bone regeneration in dehiscence defects; and - · guided tissue regeneration procedures in periodontal defects.
Device Story
Geistlich Bio-Gide® is a resorbable, bilayer porcine collagen membrane used in dental surgery. It features a porous surface for bone-forming cell ingrowth and a dense surface to prevent fibrous tissue infiltration. The device is used by dentists/periodontists in clinical settings to support guided bone and tissue regeneration. It is applied over bone defects or around implants to facilitate healing and tissue integration. The membrane is non-cross-linked and sterilized via gamma irradiation. It acts as a physical barrier, promoting predictable bone and soft tissue regeneration, which benefits patients by improving the success of dental implants and ridge reconstruction procedures.
Clinical Evidence
No new clinical data was generated. Substantial equivalence is supported by bench testing (elongation, suture pull-out, swelling, DSC, collagenase digestion, SEM) and viral safety evaluation per ICH Q5A(R1) and ISO 22442-3:2007. Biocompatibility, sterilization, shelf-life, and clinical performance data were leveraged from the applicant's own predicate devices.
Technological Characteristics
Bilayer porcine collagen membrane; non-cross-linked; porous and dense surfaces. Sterilized by gamma irradiation. Single-use. Dimensions vary by product (e.g., 13x25mm, 25x25mm, 40x50mm, 16x22mm, 14x24mm, 8mm diameter). No electronic components or software.
Indications for Use
Indicated for dental patients requiring bone or tissue regeneration, including augmentation around immediate/delayed dental implants, localized ridge augmentation, alveolar ridge reconstruction, filling of bone defects (post-root resection, cystectomy, tooth removal), guided bone regeneration in dehiscence, and guided tissue regeneration in periodontal defects.
Regulatory Classification
Identification

#### IV. Device Description
Geistlich Bio-Gide® Perio is a pure collagen membrane with a bilayer structure and smoothed dense (cell-occlusive) surface. The modified surface makes the membrane somewhat stiffer in the dry state, and this facilitates cutting the membrane for periodontal applications. The porous surface (facing the bone) allows the ingrowth of bone forming cells, and the dense surface (facing the soft tissue) prevents the ingrowth of fibrous connective tissue into the defect. The membrane is made of collagen without further cross-linking, and is sterilized by gamma irradiation.
{19}------------------------------------------------
Preformed sterile templates are provided to simplify the cutting of the respective membrane shape. Four templates (uncoated Tyvek®) are packaged with Geistlich BioGide® Perio to serve as an aid to assist the clinician in trimming the Geistlich Bio-Gide® Perio membrane to fit the defect and are in varying shapes to fit the clinical need (e.g., rectangular, interproximal).
