The effects of 40 interdental osteotomies on surrounding osseous and periodontal structures were evaluated clinically and radiographically. No statistically significant changes were noted in any of the clinical parameters except gingival height, which decreased slightly in the maxilla and increased in the mandible. These changes were found to be statistically significant, but not clinically significant, and are most likely explained by the direction of movement of the bony segment. Radiographic evaluations revealed no statistically significant changes other than an increase in interdental width in both the maxillary and mandibular sites. These measurements were made at the root level, and, although the crowns were moved closer, the roots may actually have flared apart because the anterior segment was tipped to upright the incisors. The lack of change in the other radiographic parameters indicated that there was no loss of alveolar bone support.
对40例牙间截骨术对周围骨组织和牙周组织的影响进行了临床和影像学评估。除牙龈高度外,其他任何临床参数均未发现有统计学意义的变化,上颌牙龈高度略有下降,下颌牙龈高度有所增加。这些变化具有统计学意义,但无临床意义,很可能是由骨段移动方向所致。影像学评估显示,除上颌和下颌部位的牙间隙宽度增加外,其他参数均无统计学意义的变化。这些测量是在牙根水平进行的,尽管牙冠移动得更近,但由于前段倾斜以使切牙直立,牙根实际上可能已经分开。其他影像学参数没有变化表明牙槽骨支持没有丧失。
