One of the main objectives of periodontal reconstructive surgery is the coverage of exposed roots due to gingival recession. A large variety of mucogingival grafting procedures are available that give highly predictable and esthetically acceptable results when treating intact root surfaces. However, these procedures call for a second surgery site in the palate. The present study examines a series of cases in which connective tissue, obtained from the tuberosity during pocket reduction procedures in the posterior region of the maxilla, was used for root coverage.
Forty-four teeth from 25 patients with gingival recession of 3.30 +/- 0.14 mm (mean +/- SEM) were treated with subepithelial connective tissue grafts using connective tissue obtained from the tuberosity area during pocket reduction procedures in the posterior region of the maxilla.
The mean root coverage recession after treatment was 0.16 +/- 0.06 mm, with effectiveness of coverage at 95.0% +/- 1.84 and a predictability of 84.1%. Periodontal probing depth reduction at the donor site was 4.08 +/- 0.24 mm.
These results indicate that the subepithelial connective tissue graft obtained from the tuberosity area during pocket reduction procedures in the posterior region of the maxilla provides a very predictable and esthetic root coverage without the need for a second surgical site.
牙周重建手术的主要目标之一是覆盖因牙龈退缩而暴露的牙根。有多种黏膜牙龈移植手术可供选择，在治疗完整牙根表面时能产生高度可预测且美观效果良好的结果。然而，这些手术需要在上腭开辟第二个手术部位。本研究考察了一系列病例，其中在对上颌后部区域进行袋形切除术时从结节处获取的结缔组织被用于牙根覆盖。
对25例牙龈退缩3.30±0.14毫米（均值±标准误）患者的44颗牙齿，使用在上颌后部区域袋形切除术期间从结节区域获取的结缔组织进行上皮下结缔组织移植治疗。
治疗后牙根覆盖退缩的均值为0.16±0.06毫米，覆盖有效率为95.0%±1.84，可预测性为84.1%。供体部位的牙周探诊深度减少了4.08±0.24毫米。
这些结果表明，在上颌后部区域袋形切除术期间从结节区域获取的上皮下结缔组织移植能提供非常可预测且美观的牙根覆盖，而无需第二个手术部位。
