Abstract

Objectives: To investigate the relationship between circummaxillary sutures and miniscrew-assisted rapid palatal expansion (MARPE) success in adult male patients and to evaluate the correlation between the width of the sutures and the maxilla expansion ratio.

Materials and methods: This retrospective study comprised 40 adult male patients treated with MARPE divided into a separation group (N = 20, mean age, 21.9 years) consisting of subjects with midpalatal suture opening and a nonseparation group (N = 20, mean age, 21.7 years) consisting of subjects with no midpalatal suture opening. Cone-beam computed tomography images were obtained before MARPE expansion for both groups and after expansion for the separation group. Vertical and horizontal skeletal relationships, palate length, and widths of 10 circummaxillary sutures before expansion were compared. The correlation between maxilla expansion ratio (jackscrew expansion to maxillary expansion ratio) and circummaxillary suture widths was also analyzed in the separation group.

Results: There were no significant differences in age, vertical and horizontal skeletal relationships, and palate length between the two groups. Zygomaticomaxillary, pterygomaxillary, midpalatal, and transverse palatine sutures showed significantly greater width in the separation group (P < .05). The zygomaticomaxillary suture showed the greatest difference (Δ = 0.36 mm) between the groups. The zygomaticomaxillary and pterygomaxillary sutures showed significant positive correlation with the maxilla expansion ratio (P < .01).

Conclusions: In adult male patients, greater circummaxillary suture widths before MARPE expansion, especially zygomaticomaxillary and pterygomaxillary sutures, resulted in a better chance of successful suture separation and more maxillary expansion.

通过比较成年男性患者颌周缝合线在扩张前的宽度,评估微型螺丝刀辅助快速腭扩张术的成功率。
研究目的研究成年男性患者颌周缝合与微型螺钉辅助快速腭扩展术(MARPE)成功率之间的关系,并评估缝合线宽度与上颌骨扩展率之间的相关性:这项回顾性研究包括40名接受MARPE治疗的成年男性患者,分为分离组(N=20,平均年龄21.9岁)和非分离组(N=20,平均年龄21.7岁),前者包括腭中缝开口的患者,后者包括腭中缝未开口的患者。两组受试者均在 MARPE 扩容前获得锥形束计算机断层扫描图像,分离组受试者在扩容后获得锥形束计算机断层扫描图像。比较了扩容前的垂直和水平骨骼关系、腭长和 10 条颌周缝的宽度。此外,还分析了分离组的上颌骨扩张比(颌骨扩张比与上颌骨扩张比)与颌周缝宽度之间的相关性:结果:两组患者在年龄、垂直和水平骨骼关系以及上颚长度方面没有明显差异。分离组的颧颌缝、翼颌缝、腭中缝和腭横缝宽度明显大于分离组(P < .05)。颧颌缝在两组间的差异最大(Δ = 0.36 mm)。颧颌面缝和翼颌面缝与上颌骨扩张比呈明显的正相关(P < .01):在成年男性患者中,MARPE扩张前的颌周缝合宽度越大,尤其是颧颌缝和翼颌缝,则缝合分离成功的几率越大,上颌骨扩张的幅度也越大。
