[Advance and review: miniscrew-assisted rapid palatal expansion].

Rapid palatal expansion (RPE) is commonly used to correct transverse maxillary deficiencies and recognized as a reliable orthopedic procedure in children and adolescents. For adults, however, conventional RPE has been considered rarely successful and can produce undesirable dental effects. Along with the development of digital techniques and mini-implant anchorage, a novel method called miniscrew-assisted RPE (MARPE) has become available for the treatment of maxillary transverse deficiency in older patients recently. In this article, the biomechanical principles and indications of MARPE, the advances in device design, the clinical effects, the matters needing attention and limitations of this method, and the stability after expansion are discussed.上颌快速扩弓是治疗上颌横向发育不足的常用方法，其治疗腭中缝未闭合的儿童和青少年患者的疗效较好，而对成年患者的疗效欠佳。随着数字化技术和种植体支抗的广泛应用，近年支抗种植体辅助上颌快速扩弓成为治疗成人上颌横向发育不足的新方法，但目前尚未形成完善的体系。本文从支抗种植体辅助上颌快速扩弓的矫治原理和适应证、装置结构设计的研究进展、临床疗效、注意事项和不足以及扩弓效果的稳定性5个方面进行综述，以期为临床治疗提供参考。.
