Microsurgical regenerative approach to intrabony defects

Abstract Periodontal regeneration is a validated treatment for intrabony defects, aiming to restore lost periodontal tissues through pocket depth reduction, clinical attachment, and bone gain with minimal recession. Despite its proven efficacy, outcomes vary widely due to patient‐related factors (e.g., oral hygiene and smoking), defect characteristics, and surgical techniques. Minimally invasive approaches, supported by magnification and microsurgical tools, have enhanced surgical precision and clinical predictability. This paper presents a stepwise surgical protocol for minimally invasive periodontal regeneration. Key components include incision design based on papilla width and height, careful debridement with preservation of supracrestal fibers, and tailored flap designs that ensure optimal access while preserving soft tissue integrity. Regenerative materials are selected based on defect morphology to promote clot stability and space maintenance. Advanced suturing strategies, particularly modified internal mattress sutures, enable passive primary closure and stable wound sealing. Microsurgical instruments and monofilament sutures further contribute to atraumatic tissue handling and precise closure. Successful regeneration depends on meticulous surgical execution, appropriate material selection, and integration into a comprehensive treatment plan including long‐term supportive care. This technique‐driven approach optimizes regenerative outcomes and improves prognosis for compromised teeth. Key points The precision in flap design and papilla preservation is critical. Selecting the incision type based on papilla width and height, and preserving supracrestal fibers whenever possible, minimizes tissue trauma and maximizes regenerative potential. The application of minimally invasive, microscope‐assisted approaches improves outcomes. Smaller flaps, careful debridement, and precise regenerative material placement enhance wound stability, reduce surgical trauma, and promote optimal healing. The primary closure and suture stability determine success. Achieving tension‐free, face‐to‐face wound closure with appropriate microsurgical suturing techniques is essential for protecting the regenerative site during early healing. Plain language summary Periodontal regeneration is a treatment used to rebuild the tissues that support teeth, which can be lost because of gum disease. The aim is to reduce deep gum pockets, restore the gum's attachment to the tooth, and regrow bone, while keeping gum recession as small as possible. Results can vary between patients due to factors such as oral hygiene, smoking, the type of bone defect, and the surgical method. Recent minimally invasive techniques, supported by magnification and microsurgical tools, have improved precision and predictability. This paper describes a step‐by‐step surgical approach. It includes designing small, precise incisions depending on the shape of the gum, cleaning the defect carefully while preserving healthy fibers, and lifting the gum in a way that protects soft tissue. Regenerative materials are chosen according to the defect to stabilize the blood clot and support healing. Special suturing techniques, combined with fine monofilament stitches and microsurgical instruments, allow secure wound closure with minimal trauma. Successful outcomes depend on careful surgical execution, correct material choice, and integration into a long‐term care plan. This method improves healing, stability, and the overall prognosis for teeth affected by gum disease.
