The study revealed that different incision designs have little influence on bone increment during guided bone regeneration. However, the internal gingival sulcus incision showed better postoperative soft tissue condition compared to the other two incisions.
Exploring the influence of different incision designs on bone increment of guided bone regeneration [Bio-Gide collagen membrane +Bio-OSS bone powder (carbonate apatite crystal extracted from bovine bones), Bio-OSS bone meal was placed on the surface of the bone defect and then covered with a Bio-Gide membrane to close the wound] during the same period of maxillary anterior tooth implantation. The 99 patients from the stomatology department were divided into 3 groups: small incision (N = 30, group A), wide incision (N = 39, group B), internal gingival sulcus incision (N = 30, group C). At the different time (immediately after surgery, 6 months, 12 months and 24 months), the width and height of labial bone at different implant margin (2 mm, 4 mm, 6 mm) has no significant difference in comparison of any two of the three groups (p > 0.05). The score of esthetic feeling in group A was significant higher than group C (P < 0.05). The PPD, the incidence of SH, BOP in group A were all significant higher than group B (P < 0.05). The PISm, PISd, PPD, the incidence of SH and BOP in group A were all significant higher than group C (P < 0.05). The PISm, PISd, PPD, the incidence of SH and BOP in group B were all significant higher than group C (P < 0.05). The three groups has no significant different on the influence bone increment. The soft tissue condition around the implant after surgery was better in internal gingival crevicular incision than others two incisions, large-scale incision better than small incisions. [GRAPHICS]
