This study aimed to review the literature related to the intrusion of maxillary posterior teeth in subjects needing pre-prosthetic restoration or orthodontic treatment due to anterior open bite, and to report a thin alveolar biotype case needing a pre-prosthetic intrusion of maxillary teeth by introducing a novel, personalized method of intrusion measurement. An electronic search was conducted between February 2022 and March 2022 in the following databases: PubMed, Scopus, Embase, Web of Science, and Lilacs; the terms "tooth movement techniques", "orthodontic anchorage procedures", "tooth intrusion", "intrusion", "molar", "premolar", and "human" were surveyed. Eighteen articles were included in this review; the mean amount of intrusion ranged from between 2.1 ± 0.9 mm and 4.57 ± 0.98 mm (being mostly 2-3 mm). The intrusion force varied between 100 and 500 g; 10 articles reported miniscrews (MS), 7 reported zygomatic plates (ZP), and 1 publication reported both anchorage types. The average treatment time was 6.9 months for MS and 7.9 months for ZP. Levelling the occlusal plane by intrusion of the upper posterior teeth can be achieved by skeletal anchorage. The stability of the obtained results, shortening treatment time, and controlling treatment outcome are the main goals for a complex surgical and orthodontic treatment approach.
本研究旨在回顾因前牙开牙合而需要进行修复前或正畸治疗的患者中上颌后牙压低的相关文献，并通过引入一种新颖的、个性化的压低测量方法，报告一例需要对上颌牙进行修复前压低的薄牙槽骨生物型病例。2022年2月至2022年3月期间，在以下数据库中进行了电子检索：PubMed、Scopus、Embase、Web of Science和Lilacs；检索了“牙齿移动技术”“正畸支抗程序”“牙齿压低”“压低”“磨牙”“前磨牙”和“人类”等术语。本综述纳入了18篇文章；压低的平均量在2.1±0.9毫米至4.57±0.98毫米之间（大多为2 - 3毫米）。压低力在100至500克之间；10篇文章报道了微螺钉（MS），7篇报道了颧骨板（ZP），1篇出版物报道了两种支抗类型。MS的平均治疗时间为6.9个月，ZP为7.9个月。通过骨骼支抗可以实现通过压低上颌后牙来整平牙合平面。获得结果的稳定性、缩短治疗时间和控制治疗效果是复杂手术和正畸治疗方法的主要目标。
