Abstract:
BACKGROUND: Maxillary skeletal expander is a non-surgical expansion technique of the maxilla. It is different from the traditional maxillary rapid expander, micro-implant assisted rapid palatal expansion, and surgically assisted rapid palatal expansion. It provides new ideas and methods for the correction of maxillary transverse deficiency, and especially for adult patients with the growth finished, provides an efficient and minimally invasive bone expansion. OBJECTIVE: To review the application and advantage of the maxillary skeletal expander in the treatment of maxillary transverse deficiency, providing scientific reference for the clinical therapeutic schedule in such patients. METHODS: A computer search for Cochrane Library, PubMed, Embase, Web of Science, CNKI, WanFang Database, and CBM databases was performed for Chinese and English literature related to the maxillary expansion device published before May 31st, 2019. RESULTS AND CONCLUSION: The maxillary skeletal expander is an effective method for correcting the maxillary transverse deficiency, and the expansion of the arch is not limited by age. This device also has a good outcome in bone expansion for adults. The maxillary skeletal expander expands the entire mid-face structure, causing the mid-sacral suture to be parallel, followed by ruptured palatine suture, increased width between the zygomatic bones, as well as the entire nasal cavity involving the upper nasal bone area is widened. This device also causes less adverse reactions, for example, the teeth are inclined buccally and the height of the alveolar bone is reduced.
