OpenTex®
Non-Resorbable PTFE Membrane

OpenTex® is a 100% medical grade, non-resorbable PTFE membrane with a microporous structure designed to remain a stable, predictable barrier even if exposed. Its smooth surface and small pore size resist soft tissue and fibroblast ingrowth, easing removal at re-entry — making OpenTex® a reliable choice for the Open Membrane Technique when primary closure isn't achievable.

Clinical Insight

What clinicians are saying

Real-world feedback from implantologists and periodontists using OpenTex® in their practices.

"What changed my approach to ridge preservation is not having to chase primary closure anymore. With OpenTex left intentionally exposed over a deficient socket, the membrane stays put, the site doesn't get infected, and by the time I'm ready for an implant the ridge contour is exactly what I needed."

Alveolar Ridge Preservation · Open Membrane Technique · Non-Primary Closure

"The microporous surface makes removal straightforward — there's minimal tissue ingrowth into the membrane itself, so I'm not fighting to peel it off the graft at re-entry. It's a small detail, but it changes how predictable the whole staged approach feels."

Indications

When to use OpenTex®

OpenTex® is suited to guided bone regeneration cases where large defects or thin gingiva make primary closure difficult or impossible.

Alveolar Ridge Preservation — Socket grafting after extraction to limit hard-tissue resorption ahead of future implant placement.
Open Membrane Technique — Used over large bone defects or thin gingiva where flap closure over the membrane is not achievable.
Horizontal Ridge Augmentation — Combined with a bone graft material to reconstruct deficient ridges ahead of implant placement.
GBR in Compromised Soft Tissue Sites — Suitable when soft tissue volume is insufficient for full membrane coverage.
Protection of Graft Material During Exposure — Maintains a barrier over the regeneration site even if the membrane becomes exposed.
Staged Implant Site Development — Used ahead of implant placement following a healing period after ridge preservation.
Scientific Evidence

Membrane design & published research

OpenTex® performance is supported by its validated material properties and by published clinical literature on PTFE barrier membranes for guided bone regeneration.

① Main Features

Non-Resorbable

100% medical grade PTFE membrane. Prevents resorption of bone graft material, with validated physicochemical stability and biological safety.

Withstands Exposure

Protects the tissue regeneration site even if the membrane is exposed. The procedure remains possible even when soft tissue is insufficient for full coverage.

Microporous

Enhances interstitial fluid circulation and promotes gingival tissue attachment, while resisting penetration of foreign substances and fibroblast cell migration.

② Open Membrane Technique

Non-Primary Closure

  • OpenTex® is a good option for the Open Membrane Technique when the bone defect is large or the gingiva is thin so that primary closure is not possible

Clinical Cases

Real-world clinical outcomes

Alveolar ridge preservation (ARP) using OpenTex® as an open d-PTFE membrane, from extraction through to implant placement.

Alveolar Ridge Preservation (ARP)

ARP with a d-PTFE membrane and freeze-dried irradiated allogenic bone substitute material in sockets with bone deficiency — reducing horizontal hard tissue resorption and the need for bone augmentation at the time of implant placement.

Clinical Tips

Getting the most from OpenTex®

Practical guidance for predictable outcomes with the Open Membrane Technique.

1
Use the Open Membrane Technique without forcing primary closure. OpenTex® is designed to remain a stable, predictable barrier even when left exposed — suited to large defects or thin gingiva where flap closure isn't achievable.
2
Expect straightforward removal at re-entry. The smooth, microporous surface resists soft tissue and fibroblast ingrowth into the membrane itself, which is intended to ease removal compared with membranes that integrate more closely with the wound bed.
3
Match membrane size to the defect. OpenTex® is supplied in 17×25mm and 24×30mm sizes, in a Textured surface finish.
4
Plan a staged timeline consistent with published ARP protocols. In the cited randomized controlled trial, sites were evaluated at 1 month and 4 months after ridge preservation before proceeding to implant placement.
5
Combine with a bone graft material as part of the technique. OpenTex® is intended to protect graft material at the defect site rather than replace it — pair with an appropriate bone substitute as part of the regenerative procedure.
⚠ Clinical Notice: OpenTex® is a non-resorbable PTFE membrane intended for use by trained dental and oral surgical practitioners as part of guided bone regeneration or ridge preservation procedures. As a non-resorbable device, it requires a second surgical step for removal. Store per manufacturer instructions and do not use if packaging is damaged or sterility is compromised. Refer to the Instructions for Use for full indications, contraindications, and handling guidelines.
