The aim of this paper was to describe a new surgical technique designed to preserve interdental tissue in guided tissue regeneration. This procedure was created to specifically regenerate wide intrabony defects in the esthetic zone. Fourteen subjects with an intraosseous defect in the maxillary incisor region took part in this clinical study. The defects were treated with bioresorbable membranes in combination with a bovine bone mineral graft. At baseline and at 12 months after surgery, the following clinical parameters were measured: full-mouth plaque scores, full-mouth bleeding scores, probing pocket depths, clinical attachment levels, and gingival recession. A significant gain in clinical attachment level (4.57 +/- 0.65 mm) and a reduction in probing depths (5.14 +/- 0.95 mm) were reported 12 months after surgery. The surgical technique allowed complete flap closure in every treated site, resulting in significant improvement of the clinical parameters; thus, it appeared especially appropriate for the treatment of wide defects in the esthetic zone.
本文的目的是描述一种旨在保留引导组织再生中牙间组织的新手术技术。该手术方法专门用于上颌前牙区宽大骨内缺损的再生。14例上颌切牙区存在骨内缺损的受试者参与了这项临床研究。缺损采用可生物吸收膜联合牛骨矿物质移植治疗。在基线期和术后12个月，测量了以下临床参数：全口菌斑评分、全口出血评分、探诊袋深度、临床附着水平和牙龈退缩。术后12个月报告临床附着水平有显著增加（4.57±0.65毫米），探诊深度减少（5.14±0.95毫米）。该手术技术使每个治疗部位的皮瓣完全闭合，导致临床参数显著改善；因此，它似乎特别适合治疗美学区域的宽大缺损。
