Minimally invasive techniques for repairing soft tissue defects around implants focus on tunnel techniques and envelope techniques. When combined with autologous connective tissue grafts, they remain the most reliable "gold standard" for efficacy. Xenogeneic collagen matrices can avoid donor site damage with acceptable efficacy. Platelet-rich fibrin and laser assistance primarily play a synergistic role in optimizing healing. Minimally invasive procedures offer significant advantages in preserving blood supply, reducing complications, and improving patient experience. Clinical selection should comprehensively consider the type of defect, material characteristics, and surgeon experience. Future development should move toward more precise and minimally invasive approaches.
