What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine which of three different collagen membranes lasts the longest in dental and oral surgery. These membranes aid healing and tissue growth, and identifying the most durable one can enhance treatment plans. Researchers will place these membranes near participants' upper back teeth and monitor their breakdown over time. This study is double-blind, so neither patients nor researchers know which membrane is used. It suits adults in good health with healthy gums. As an unphased trial, it allows participants to contribute to advancements in dental care and improve future treatment options.

Do I need to stop my current medications for this trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that these collagen membranes are safe for use in dental procedures?

Research has shown that the three types of collagen membranes in the study are generally well-tolerated by people.

For the BioMend Extend membrane, studies indicate that its special structure enhances stability and compatibility with the body. This design reduces the need for additional surgeries, as the membrane breaks down slowly and safely over time.

The Jason membrane, with its simpler structure, is commonly used in dental procedures. It breaks down faster than more complex membranes but remains safe and effective. Studies have shown it works well without causing major side effects.

Lastly, the OSSIX Agile membrane uses a sugar-based process to enhance its connection with body tissue. This method demonstrated excellent safety and low reaction rates in patients.

Overall, research supports the safe use of all three collagen membranes. They are designed to aid healing and are generally well-tolerated by patients.¹ ² ³ ⁴ ⁵

Why are researchers excited about this trial?

Researchers are excited about the different collagen membranes being studied for bone regeneration because they offer unique ways to enhance healing. The Membrane BioMend Extend is cross-linked with glutaraldehyde, which can provide greater stability and slower degradation, potentially leading to more effective bone support over time. Membrane Jason is non-cross-linked, allowing for faster integration with natural tissue, which could speed up the healing process. The Membrane OSSIX Agile utilizes ribose cross-linking, which might offer a balanced degradation rate with excellent tissue compatibility. These features could lead to improved outcomes compared to existing options, mainly non-cross-linked membranes, by either enhancing stability, integration speed, or tissue compatibility.

What evidence suggests that this trial's collagen membranes could be effective for bone regeneration?

This trial will compare the effectiveness of three different collagen membranes for bone regeneration: BioMend, Jason, and OSSIX. Research has shown that both cross-linked and non-cross-linked collagen membranes aid in bone healing and tissue growth. BioMend, a cross-linked membrane, is stronger and more tear-resistant, but studies have indicated it doesn't significantly improve bone regrowth compared to non-cross-linked membranes. The Jason membrane, which is non-cross-linked, breaks down completely in about 6 hours and is often used for dental bone and tissue repair. OSSIX, with its special ribose cross-linking, might lower the risk of exposure, potentially enhancing bone healing. All these membranes effectively support bone regrowth after surgery. Participants in this trial will be randomized to receive one of the various combinations of these membranes.¹ ⁶ ⁷ ⁸ ⁹
