摘　　要：上颌横向发育不足(MTD)是在各年龄阶段常见的错[牙合]畸形之一,对患者口颌面发育及功能可造成不同程度的影响,其主要治疗手段为上颌扩弓。传统观点认为,对青春后期及成年患者使用快速上颌扩弓、手术辅助上颌快速扩弓等方法存在一定弊端。近年来,微型种植钉辅助上颌快速扩弓凭借其显著优势成为了治疗青春后期及成年MTD患者的新方法;然而,其装置设计、植入部位、扩弓疗效及并发症等也存在争议。作为一种特殊类型的种植钉辅助上颌快速扩弓装置,上颌骨性扩弓器将4枚微型种植钉植入上腭后部的双层骨皮质,治疗青春后期及成年患者效果显著。本文将对上颌骨性扩弓器的生物学及生物力学基础、装置设计、临床应用、治疗效果等方面进行综述。Maxillary transverse deficiency(MTD),a common malocclusion in people of all ages,affects gnathostomatic development and functions of patients at different degrees,and its main treatment is maxillary expansion.Traditionally,rapid maxillary and surgically assisted rapid palatal expansions have several disadvantages in the treatment of late adolescence and adult patients.At present,miniscrew assisted rapid palatal expansion(MARPE)has emerged as a new treatment with significant advantages in late adolescence and adult patients with MTD.However,the device design,implant sites,curative effect,and complications of MARPE are also controversial.As a special type of MARPE,maxillary skeletal expander(MSE)is positioned at the posterior palate,with four microimplants engaging the palatal bone bicortically.Such positioning results in significant expansion in late adolescence and adult patients.This article aims to review MSE in terms of biological and biomechanical bases,device design,clinical application,and curative effect.
