This meta-analysis evaluated long-term dental and skeletal changes in patients submitted to surgically assisted rapid maxillary expansion.
A search was performed in electronic databases. Human clinical trials with patients submitted to surgically assisted rapid maxillary expansion with a follow-up of at least 1 year after expansion were selected. A methodological quality scoring process was used. A meta-analysis was performed to compare measurements of skeletal and dental structures.
Three hundred sixty-five titles and abstracts were read. Ultimately 10 studies met the inclusion criteria. The 3 articles ranked as presenting low methodological quality were excluded. Three measurements could be compared and 3 time periods were used to assess changes.
There is moderate evidence to conclude that maxillary alveolar width and intercanine and intermolar width have a long-term significant increase as a result of surgically assisted rapid maxillary expansion. A significant relapse is expected in the intercanine width after expansion.
本荟萃分析评估了接受手术辅助上颌快速扩弓治疗的患者的长期牙齿和骨骼变化。
在电子数据库中进行了检索。选择了接受手术辅助上颌快速扩弓治疗且扩弓后随访至少 1 年的人类临床试验。使用了方法学质量评分过程。进行了荟萃分析以比较骨骼和牙齿结构的测量值。
阅读了 365 篇标题和摘要。最终有 10 项研究符合纳入标准。将 3 篇被评为方法学质量低的文章排除在外。可以比较 3 项测量值，并使用 3 个时间段来评估变化。
有中等证据表明，上颌牙槽宽度以及尖牙间宽度和磨牙间宽度由于手术辅助上颌快速扩弓而长期显著增加。扩弓后预计尖牙间宽度会出现明显的复发。
