 根上附着体的去模制作过程

           精密附着体，虽然戴入口中固位好美观等优点，但是过程繁琐，时间周期较长，取模的难度较大。尤其是对于无牙牙合的只剩下牙根或在种植体上制作附着体的患者较其他的牙列缺损的难度更大，因为不但有牙槽嵴的精确印模还要把握附着体的准确对位。看看下面的过程可以 作为参考。

                                                                                                 根管预备的口内示意图

                                                                                        和备冠一样的排龈取模灌模

                                                                                      桩根帽的制作完成

                                                                             在桩根帽上开始研磨根上附着体部件

                                                                                                     螺纹的研磨

                                                                                        根上部件完成模型观

                                                                                                          口内的试戴

                                                                                                粘接桩根帽

                                                                             在上端的分瓣簧上安装转移帽                                           

                                                                                            转移帽安于桩根帽上

                                                                                    取模后将转移杆安到印模上灌注石膏

                                                                                    转移杆的放置

                                                                                              灌注石膏模

                                                                              取模时区别于普通印模的个别托盘

                                                                              完成的义齿组织面安放附着体的帽状装置

                                                                             本病例的附着体的固位装置图就位后的

                                                                                  摘出时候的固位帽的变化

                                                                  这是调整附着体的固位力的一套工具

             还有很多病例的总结以后有机会交流。
