The appropriate alignment of the lower teeth is indicated by the Curve of Spee (COS), which can be observed in the sagittal profile view of human skulls. Graf Von Spee made the initial observation on this occlusal curvature. Through this systematic review and meta-analysis, we evaluated studies that looked at how COS affected masticatory activities.
The databases PubMed-MEDLINE, Web of Science, Cochrane, and Scopus were all searched. A total of 12 documents were ultimately picked because they met the necessary inclusion and exclusion requirements. The data was then loaded into the RevMan 5 programme for meta-analysis after being chosen for information on the sample size, variables analyzed, and various aspects of the research.
The Curve of Spee was found to have a noticeable impact on both the masticatory efficiency as well as dentofacial alignment in the 12 studies that we selected for the review and meta-analysis. In addition, other occlusal curvatures such as the Curve of Monson and the Curve of Wilson were found to be of vital importance on a similar level to the COS. The meta-analysis further revealed that seven of the included clinical trials had mentioned the noticeable impact on masticatory efficiency.
This study focused on the significance of the COS on force distribution in the oral cavity as well as the necessity of COS corrections after receiving full orthodontic care. Following orthodontic treatment, the COS, along with other occlusal curves such as the Curve of Wilson and the Curve of Monson, is essential in removing strains from the condyle, as well as the maxilla and mandible, which enhances masticatory effectiveness and lessens the overall strain on a patient's oral cavity.
斯皮曲线（COS）可指示下牙的正确排列，在人类头骨的矢状面视图中可以观察到该曲线。格拉夫·冯·斯皮最先观察到这种咬合曲线。通过本系统评价和荟萃分析，我们评估了研究斯皮曲线如何影响咀嚼活动的研究。
检索了PubMed-MEDLINE、科学网、Cochrane和Scopus数据库。最终共挑选出12篇文献，因为它们符合必要的纳入和排除标准。在选择了关于样本量、分析变量和研究的各个方面的信息后，将数据加载到RevMan 5程序中进行荟萃分析。
在我们选择进行综述和荟萃分析的12项研究中，发现斯皮曲线对咀嚼效率和牙面排列均有显著影响。此外，还发现其他咬合曲线，如蒙森曲线和威尔逊曲线，与斯皮曲线具有同等重要的意义。荟萃分析进一步显示，纳入的7项临床试验提到了对咀嚼效率的显著影响。
本研究关注斯皮曲线对口腔内力量分布的重要性以及在接受全面正畸治疗后矫正斯皮曲线的必要性。正畸治疗后，斯皮曲线与威尔逊曲线和蒙森曲线等其他咬合曲线对于消除髁突以及上颌骨和下颌骨的应力至关重要，这可提高咀嚼效率并减轻患者口腔的整体应力。
