The objective of this article was to report two clinical cases, showing the benefits of interceptive treatment using rapid palatal expansion (RPE) and the preservation of E-space.
It is important to follow-up child throughout its development to detect irregularities in their occlusion and to avoid or attenuate orthodontic treatments in the future. Posterior crossbite and transverse maxillary deficiency can easily be corrected by RPE that enhances the width of the maxilla and promotes a gain of space in the arch. Another way to gain space in the arch is by using the E-space, which is the difference between the mesiodistal distance of the second primary molar in relation to the second premolar. This additional space can be used to resolve negative, mild, or moderate crowding.
Two clinical cases that presented malocclusions due to lack of space and maxillary deficiency, along with clinical technic of how the RPE and E-space can be used to bring those patients back to normality.
We concluded that with a right diagnosis, correct interceptive timing, and using what growth provides, the development can be reestablished.
The clinical importance of this report is that RPE and E-space are efficient interceptive orthodontic treatments to correct skeletal posterior crossbite (SPC) and gain space in dental arches.

本文的目的是报告两例临床病例，展示使用快速腭扩展（RPE）进行阻断性治疗以及保留E空间的益处。
在儿童的整个发育过程中进行随访，以检测其咬合异常并避免或减轻未来的正畸治疗，这一点很重要。后牙反合和上颌横向发育不足可通过RPE轻松矫正，RPE可增加上颌宽度并促进牙弓获得间隙。在牙弓中获得间隙的另一种方法是利用E空间，E空间是第二乳磨牙与第二前磨牙近远中距离的差值。这个额外的间隙可用于解决阴性、轻度或中度牙列拥挤。
两例因间隙不足和上颌发育不足导致错牙合畸形的临床病例，以及如何使用RPE和E空间使这些患者恢复正常的临床技术。
我们得出结论，通过正确的诊断、正确的阻断时机以及利用生长所提供的条件，可以重建发育。
本报告的临床重要性在于，RPE和E空间是矫正骨骼性后牙反合（SPC）和在牙弓中获得间隙的有效阻断性正畸治疗方法。
