Abstract: Objective　 28 cases of immediately planted upper front teeth, soft tissue of which were reconstructed with the transplantation of free connective tissue flap ,were retrospectively analyzed. Methods　28 cases of transplantation of free connective tissue flap of immediately planted upper front teeth were completed by the same dentist between December 2012 and May 2013, in which 28 implants were embedded immediately, with teeth dragged without flap by way of non-burying. In palatal side lobe the flap of isolated connective tissue was cut off and the reconstruction with the transplantation of free connective tissue flap was retrospectively analyzed and studied in order to observe the situation of the survival of tissue flap and the prospect of reconstruction of implant soft tissue after surgeon. Results　Free connective tissue flap healed very well with 96.43% clinical survival rate. In addition, the soft tissue morphology achieved the expected results with higher scores on pink esthetic score (PES), and reconstruction of soft tissue attained the aesthetic effect. Conclusion　The reconstruction of soft tissue which was immediately embedded in upper front single planted teeth is safe and reliable as well as convenient for disc with short surgical time so that it can be viewed as a reasonable choice of the soft tissue reconstruction.
