Figure 4 The outcomes of regenerative treatment for the mandibular left second molars. A: Primary wound healing at the 2 wk after surgery; B: The parallel film showed 100% bone fill in the distal intrabony defects at 2 wk postoperatively; C: No gingiva accession appeared around the second molar at 9 months postoperatively; D: The radiographic bone gain remained satisfactory at the distal site according to the parallel film.
