BioHorizons Striate+™ Dual Layer Dental Membrane

Striate+ is a non-cross-linked, acellular type I collagen, which does not induce an abnormal inflammatory response and minimizes the risk of wound dehiscence. Its innovative bilayer design allows it to readily conform to bone surfaces.

The smooth and rough sides allow it to stimulate specific biological responses. The smooth side facing the soft tissue consists of densely packed collagen bundles arranged in parallel, which, in their barrier function, prevent the migration of the epithelial cells into the defect.

The rough side, which faces the bone defect, consists of a porous network of collagen fibers, forming an open scaffold promoting osteogenesis, referred to as the "bioactive chamber". Thus, Striate+ was developed to protect the bone graft from epithelial cell ingrowth and to create a favorable environment for osteogenesis, with a predictable resorption time for protected bone regeneration.

Furthermore, Striate+ exhibits excellent handling and usability. It can be applied without prior hydration, gently adheres and conforms to a defect, and can be stabilized by suturing. I found Striate+ to have a higher mechanical strength than other products on the market. The membrane absorbs fluids by capillarity but does not swell excessively, facilitating primary closure and making it particularly suitable for patients with a thin periodontal biotype.

Seven practitioners, including both general dentists and periodontists who serve as clinical product evaluators for Catapult Education, were given the Striate+ collagen membrane to use in their everyday clinical cases.

These advanced procedures included but were not limited to implant placement, bone regeneration, and tissue repair. As evaluators, we focused on its handling, adaptability, effectiveness, and versatility for achieving predictable clinical outcomes in various surgical scenarios. At the end of the evaluation period, we were all asked to provide unbiased feedback based on our clinical experience with Striate+.

We found Striate+ to be highly adaptable to various surgical scenarios. In comparison with other commonly used brands on the market, we noted positive feedback for its enhanced handling and adaptability. A significant majority rated Striate+ as “better” or “much better” than their current membranes, emphasizing its advantages in challenging surgical situations.

The typical challenges with other membranes, which were minimized with Striate+, include loss of control at placement, difficult manipulation, decreased rigidity/stiffness when moistened, and collapse into the site. Striate+ was particularly well received for its handling, with around half of evaluators rating it as “better” and a third as “much better” compared to their customarily used membranes. Evaluators favorably noted its ability to “conform well to the site” without excessive rigidity, making placement easier.

Postoperative outcome feedback was also positive, with evaluators observing effective wound support and healthy tissue response with minimal inflammation and smooth integration.
