The purpose of this article has been to increase the restorative dentist's appreciation for the rationale justifying preprosthodontic orthodontic treatment. It has not been intended to identify all the specific indications for the use of orthodontic treatment to enhance prosthodontic treatment nor has it been intended as a reference to assist the restorative dentist in placing and using orthodontic appliances. Figure 12 illustrates a typical case in which the combination of orthodontic and prosthodontic treatment resulted in a more favorable outcome than prosthodontic treatment alone. When planning prosthodontic treatment, the dentist should embrace a dynamic view of tooth position and determine whether restorative treatment can be enhanced by tooth movement. Improved tooth position can eliminate potentially pathologic occlusion and create a healthier periodontal environment that is easier to maintain. In addition, it permits the dentist to place restorations that often require less natural tooth reduction during preparation, and that are more esthetic, functional, stable, and durable. Orthodontic treatment that accomplishes these benefits may be limited to a partial fixed appliance localized to one segment of an arch or require a more extensive fixed appliance. Much of this treatment can be accomplished by the interested restorative dentist. Addressing more comprehensive orthodontic problems in patients requiring prosthodontic care is best managed through a restorative dentist and orthodontist team approach to treatment.
本文的目的是增强修复牙医对牙体修复前正畸治疗基本原理的认识。本文并非旨在确定使用正畸治疗来加强修复治疗的所有具体适应症，也不是作为协助修复牙医放置和使用正畸矫治器的参考资料。图12展示了一个典型案例，其中正畸治疗与修复治疗相结合比单纯的修复治疗产生了更理想的效果。在计划修复治疗时，牙医应从动态角度看待牙齿位置，并确定牙齿移动是否能加强修复治疗。改善牙齿位置可消除潜在的病理性咬合，并创造一个更健康、更易于维护的牙周环境。此外，这使牙医能够在制备修复体时减少对天然牙体组织的磨除，且修复体更美观、功能更好、更稳定耐用。实现这些益处的正畸治疗可能仅限于局部固定矫治器，其位于牙弓的某一段，或者可能需要更广泛的固定矫治器。许多这类治疗可由感兴趣的修复牙医完成。对于需要修复治疗的患者中更复杂的正畸问题，最好通过修复牙医和正畸医生的团队治疗方法来处理。
