For years, the treatment for the replacement of a missing tooth was a fixed dental prosthesis. Currently, implants are indicated to replace missing teeth due to high clinical success and with the advantage of not performing preparations in the adjacent tooth. Another option for space closure is the use of orthodontics associated to miniscrews for anchorage allowing better control of the orthodontic biomechanics and especially making possible closure of larger prosthetic spaces. Thus, this article describes two cases with indications and discussion of the advantages and disadvantages of using orthodontics for prosthetic spaces closure. The cases herein presented show that it is possible to close an space when there are available teeth in the adjacent area. It can be concluded that when a malocclusion is present there will be a strong trend to indicate space closure by orthodontic movement as it preserves natural teeth and seems a more physiological approach.
多年来，缺失牙的治疗方法是固定义齿修复。目前，由于种植牙具有较高的临床成功率，且无需对邻牙进行预备，因此被用于替代缺失牙。关闭间隙的另一种选择是使用正畸治疗并结合微型螺钉作为支抗，这样可以更好地控制正畸生物力学，尤其能够实现更大修复间隙的关闭。因此，本文描述了两例关于使用正畸方法关闭修复间隙的适应证及优缺点讨论的病例。本文呈现的病例表明，当邻区有可用牙齿时，关闭间隙是可行的。可以得出结论，当存在错颌畸形时，正畸移动关闭间隙的趋势会很强，因为这样能保留天然牙，且似乎是一种更符合生理的方法。
