In a recent "Just Ask" online seminar, hosted by Stephan, Professor Martina Stefanini shared valuable insights on harvesting connective tissue grafts, with a focus on techniques and considerations for optimal results. The seminar, which attracted participants from all over the world, was a deep dive into one of the most critical aspects of dental surgery—tissue harvesting.
Martina, a renowned expert from Italy, discussed how the quality of connective tissue grafts significantly influences the success of treatments, particularly when dealing with delicate cases like gingival recession. She emphasized that while surgical techniques, such as the "trapdoor" and "envelope" methods, are important, the true key to success lies in the graft's quality. Specifically, the connective tissue graft's ability to provide stability and proper coverage is paramount for ensuring long-term healing and aesthetic results.
She provided a detailed look at the anatomical considerations when harvesting from the palate, highlighting the importance of minimizing risks to the palatal artery. In addition to technique, the patient’s anatomy must be assessed carefully to avoid complications like bleeding or graft necrosis. The depth of tissue harvesting also plays a crucial role in postoperative recovery, with deeper incisions generally resulting in more discomfort for the patient.
Martina’s discussion also covered the patient experience, noting that the postoperative pain is more closely tied to the depth of the graft removal than to the type of healing (primary vs. secondary). For this reason, techniques that preserve the periosteum and reduce tissue trauma, such as using magnification during surgery and minimizing unnecessary cuts, can improve patient outcomes.
The session concluded with a focus on the practical aspects of tissue grafts—how to avoid common pitfalls like leaving epithelial remnants and ensuring stable grafts by avoiding glandular tissue. Martina shared her own tips, including the use of magnification and a new blade to ensure precise tissue removal, and discussed how to manage post-surgical care to avoid complications.
This engaging seminar offered dental professionals a wealth of practical knowledge, shedding light on both the science and art of connective tissue harvesting, and left participants eager to apply these insights to their own practices.
