图1 集中𬌗型全口义齿的咬合接触分析Figure 1 Occlusal contact analysis of the complete denture with the centralized occlusal scheme A, centric occlusion, color bar representing the interocclusal distance, with green indicating larger gaps and red indicating closer contact; B, centric occlusion; C, protrusive balanced occlusion; D, lateral balanced occlusion (left as working side); E, lateral balanced occlusion (left as balancing side); B-E color bar representing the interocclusal distance, with red indicating larger gaps and blue indicating closer contact. |
图2 集中𬌗型与传统𬌗型的咬合接触面积及咀嚼效率比较分析Figure 2 Comparative analysis of occlusal contact area and masticatory efficiency between the centralized and conventional occlusal schemes A, distribution of occlusal contact points in the conventional occlusal scheme; B, distribution of occlusal contact points in the centralized occlusal scheme; occlusal contact points on the maxillary dentition are shown in blue; C, quantitative comparison of masticatory efficiency between the two occlusal schemes for 5 patients. *P < 0.05. |
