The periodontal response to vertical osteotomy was evaluated in seven males and ten females, aged 14-45 years (mean 26.8), who were scheduled for maxillary and/or mandibular segmental osteotomies. Plaque and gingival indices, pocket depth, clinical attachment level, width of attached gingiva, and osseous support were recorded from teeth adjacent to each osteotomy site prior to and from six months to three years after surgery. In each patient teeth numbers 3, 9, 13, 19, 25, and 29 were used as controls. There was no significant (P less than or equal to 0.05) difference between experimental and control teeth with respect to plaque, gingivitis, pocket depth, or clinical attachment level. Slightly decreased osseous support and width of attached gingiva were found adjacent to osteotomy sites. However, although these decreases were statistically significant (P = 0.005), they were not clinically very large. It was concluded that segmental osteotomies, in general, may be performed without producing significant changes in the periodontal structures.
对7名男性和10名女性（年龄14 - 45岁，平均26.8岁）进行了评估，这些患者计划接受上颌和/或下颌节段性截骨术，以观察垂直截骨术对牙周组织的影响。在手术前以及术后6个月至3年期间，记录每个截骨部位相邻牙齿的菌斑指数、牙龈指数、牙周袋深度、临床附着水平、附着龈宽度和骨支持情况。在每位患者中，第3、9、13、19、25和29号牙齿作为对照。在菌斑、牙龈炎、牙周袋深度或临床附着水平方面，试验牙和对照牙之间没有显著（P≤0.05）差异。在截骨部位相邻处发现骨支持和附着龈宽度略有减小。然而，尽管这些减小在统计学上具有显著性（P = 0.005），但在临床上变化不大。研究得出结论，一般来说，节段性截骨术的实施可能不会引起牙周结构的显著改变。
