What You Need to Know Before You Apply

What is the purpose of this trial?

To correct gum recession, patient's own tissue from the roof of the mouth is harvested and placed where there is root exposed. This is considered gold standard of treatment. Sometimes patient don't want to have second surgical site in their mouth and at the same time do not want to use alternative tissue from human or animal donor. Using patients' blood and preparing it as a membrane is the next best thing to correct gum recession.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

Is the Autologous Blood Membrane Technique for Gum Recession safe?

Soft tissue grafts, including those used for gum recession, are generally considered safe with few minor complications. A rare complication, like an unusual wound healing, can occur but is typically manageable with further treatment. ^{1 2 3 4 5}

How does the Autologous Blood Membrane Technique for Gum Recession differ from other treatments?

The Autologous Blood Membrane Technique is unique because it uses the patient's own blood to create a membrane that aids in healing gum recession, potentially offering a more natural and regenerative approach compared to traditional grafting methods that use donor tissue or synthetic materials. ^{4 5 6 7 8}

What data supports the effectiveness of the Autologous Blood Membrane Technique for treating gum recession?

Research shows that using autologous blood products, which contain healing components like platelets and growth factors, can help improve the healing and regeneration of gum tissue. These products are used alongside traditional gum grafting techniques to enhance outcomes, such as better root coverage and improved tissue quality. ^{9 10 11 12 13}

Interventions

• Soft Tissue Grafting

Trial Overview The study tests the use of patients' own blood prepared as a membrane versus traditional grafting from the roof of the mouth for treating gum recession. It's a split-mouth design, meaning each patient receives both treatments in different areas.

How Is the Trial Designed?

Group I: All Participants Experimental Treatment 1 Intervention

Participants will receive the CTG procedure on one side and the PRF procedure on the other. Both are standard of care soft tissue grafting methods and a split mouth design is standard of care.

The use of autologous blood products (ABPs) in mucogingival surgery showed no adverse events and led to satisfactory treatment outcomes, suggesting they are safe and effective adjuncts to traditional grafting procedures.

ABPs may particularly benefit patients with local or systemic complications, enhancing the predictability of clinical and esthetic results in mucogingival treatments.

In a study involving 14 patients with 20 cases of gingival recession, both acellular dermal matrix allograft (ADMA) and subepithelial connective tissue graft (SCTG) showed significant improvements in recession height, recession width, and keratinized gingiva after six months, indicating their effectiveness in treating gingival recession.

The results demonstrated that ADMA is a viable alternative to SCTG, as both techniques produced similar outcomes in root coverage and other clinical parameters, suggesting that ADMA can be used without compromising treatment efficacy.

Mucogingival plastic surgery aims to achieve complete root coverage and aesthetic blending of treated and untreated tissues, addressing the growing demand for cosmetic dental procedures.

While the connective tissue graft is often seen as the best option for treating gingival recession, the choice of surgical technique should be based on a careful evaluation of individual patient and defect characteristics, as all root coverage methods can be effective under real-world conditions.

Minimally invasive coronally advanced flap-based surgical techniques for treating gingival recession may offer improved esthetic results and reduced patient discomfort compared to traditional methods that use autogenous tissue, which can cause more morbidity.

This review evaluates five specific minimally invasive techniques, highlighting their clinical applications and potential benefits in achieving effective root coverage with less impact on patient well-being.

In a study of 18 patients with gingival recession, the tunnel technique combined with subepithelial connective tissue graft (TUN+CTG) showed significantly better clinical outcomes than the coronally advanced flap with enamel matrix derivative (CAF+EMD) after 5 years, with 50% of TUN+CTG sites achieving complete root coverage compared to 0% for CAF+EMD.

The TUN+CTG technique also resulted in greater recession reduction and thicker marginal soft tissue, indicating improved aesthetic outcomes, although there were no significant differences in patient-centered satisfaction between the two techniques.

In a study involving rats with mucogingival defects, both bacterial cellulose matrix (BCM) and human acellular dermal matrix (ADM) seeded with fibroblasts showed healing results comparable to the gold-standard free gingival grafts (FGGs) after 15 days.

Among the engineered grafts, ADM demonstrated the best clinical and histological outcomes, suggesting its potential as an effective treatment option for mucogingival defects in humans.

A new bioabsorbable bilayer collagen membrane has been successfully used to treat gingival recession, offering a less invasive alternative to traditional soft tissue grafts by eliminating the need for donor site surgery.

This membrane adapts well to bone and tooth surfaces, stabilizing without sutures, and has shown effectiveness in both guided bone regeneration and periodontal defect treatments.

A case report highlights a rare complication of an arterio-venous shunt that occurred after the removal of palatal mucosa for a soft tissue graft in periodontal treatment.

The complication was successfully managed through surgical excision, and the healing process following the procedure was uneventful, indicating that while complications can occur, they can often be effectively treated.

Soft tissue grafts are effective in treating various mucogingival deformities, such as ridge deficiencies and lack of keratinized tissue, which can improve both function and aesthetics around teeth and edentulous ridges.

The article details different types of autologous soft tissue grafts, including free and pedicle grafts, and discusses their specific advantages and limitations for various dental conditions.

Guided tissue regeneration (GTR) using resorbable collagen membranes is an effective alternative to traditional soft tissue grafts for treating gingival recession, as it eliminates the need for a second surgery to harvest donor tissue.

The collagen membranes not only serve as effective barriers to promote healing but also enhance the thickness of the gingiva and may aid in early wound healing due to their platelet-aggregating properties.

The technique of using coronally advanced gingival flaps combined with rhPDGF-BB-saturated graft material shows significant effectiveness in achieving root coverage and improving the aesthetic appearance of recession defects in periodontal treatment.

This method not only provides excellent cosmetic results but also promotes periodontal regeneration, including the potential for new cementum, periodontal ligament, and alveolar bone formation, which is a notable advantage over traditional repair techniques.
