The reconstruction of functionally appropriate contacts between antagonistic teeth substantially determines the quality of prosthetic-restorative work. In a population-based sample comprising 2597 subjects, static occlusal contacts were registered and analysed using the GEDAS (Greifswald Digital Analyzing System), which digitally represents the contact point situation by means of silicone bite impressions. The number of contacting teeth is approximately equal on the Left- and right-hand side amounting to 8.3 on the left and 8.4 on the right. Furthermore, it was shown that 39% of the maxillary bridge pontics and 33% of the mandibular bridge units are not in contact. Antagonistic contacts are missing in 41% of the maxillary and 39% of the mandibular removable denture teeth. These results show that the fabrication of fixed dentures, particularly in bridge pontics, and the inspection of removable dentures needs to be done with more care to this detail.
拮抗牙之间功能合适的接触重建在很大程度上决定了修复性治疗工作的质量。在一个包含2597名受试者的基于人群的样本中，使用GEDAS（格赖夫斯瓦尔德数字分析系统）记录并分析静态咬合接触，该系统通过硅橡胶咬痕数字化呈现接触点情况。左右两侧接触牙的数量大致相等，左侧为8.3颗，右侧为8.4颗。此外，结果显示上颌桥体的39%和下颌桥体单元的33%未形成接触。上颌可摘义齿41%的牙齿和下颌可摘义齿39%的牙齿缺少拮抗接触。这些结果表明，固定义齿的制作，尤其是桥体部分，以及可摘义齿的检查需要更加关注这一细节。
