Stability improvement in adult maxillary transverse deficiency after surgically assisted rapid maxillary expansion: a Meta-analysis / 中国组织工程研究

ABSTRACT

BACKGROUND: Surgically assisted rapid maxillary expansion (SARME) has been proved to exert good therapeutic efficacy on maxillary transverse deficiency (MTD) in adults, but its long-term efficacy and stability still remain controversial.OBJECTIVE: To analyze the stability improvement in adult MTD after SARME through a Meta-analysis.METHODS: A computer-based search of PubMed, Medline, EMBASE, Central Register of Controlled Trials, CNKI, and WanFang databases was conducted for the randomized, quasi-randomized controlled trials and clinical case-control trials published before May 31st, 2015. The quality evaluation and data extraction in the middle- and high-quality literature were performed by two professional researchers independently, and a Meta-analysis was then performed using Revman5.3 software.RESULTS AND CONCLUSION: Totally 13 articles involving 513 cases were included. The results of Meta-analysis showed that: (1) the stability of the teeth: the difference of the first molar (WMD=-1.03, 95%CI: -2.00--0.06), canine (WMD=-1.26, 95%CI: -2.02 to -0.49) had significant difference after surgery and the follow-up; (2) the stability of the bone: the maxillary alveolar width of the first molar (WMD=-0.43, 95%CI: -1.82 to 0.97) at post-operation and the follow-up had no significant difference; (3) the stability of the nasal airway: in the short-term, the function of the nasal airway was improved significantly, while the long-term efficacy needed to be confirmed further. To conclude, after SARME, the dental and the maxillary alveolar in adult MTD have kept long-term stability, and the nasal airway is improved significantly in short-term.
