The features that constitute an "ideal" functional occlusion have not been conclusively established. Orthodontic treatment has the capacity to change static and functional occlusal relationships fundamentally. In this article, we present the evidence on which features of the occlusion are reported to be detrimental to the teeth and masticatory system Deficiencies in this research area are highlighted, together with the need for prospective longitudinal trials to clarify the requirements of an ideal functional occlusion Based on the existing evidence this paper suggests which occlusal features may be significant in producing an "ideal" functional occlusion As no long-term studies exist to measure the impact of non-ideal occlusal relationships on the dentition, it is debatable whether orthodontic treatment should be prolonged in order to ensure that "ideal" occlusal contacts are achieved As the occlusion tends to "settle" in the period following appliance removal, we propose that it may be more appropriate to examine the functional occlusal relationships after retention has ceased rather than prolong active orthodontic treatment to achieve "ideal" functional occlusal goals.
构成“理想”功能咬合的特征尚未最终确定。正畸治疗有能力从根本上改变静态和功能咬合关系。在本文中，我们阐述了据报道哪些咬合特征对牙齿和咀嚼系统有害的证据。突出了该研究领域的不足，以及进行前瞻性纵向试验以阐明理想功能咬合要求的必要性。基于现有证据，本文提出了哪些咬合特征可能对产生“理想”功能咬合具有重要意义。由于尚无长期研究来衡量非理想咬合关系对牙列的影响，正畸治疗是否应延长以确保实现“理想”咬合接触存在争议。由于咬合在矫治器拆除后的一段时间内趋于“稳定”，我们建议，与其延长积极的正畸治疗以实现“理想”功能咬合目标，不如在保持期结束后检查功能咬合关系可能更为合适。
