Excessive movement of the underlying tissue bed can lead to poor retention of an implant-retained silicone auricular prosthesis. This article describes a 2-step impression technique with a secondary functional pickup impression of the wax pattern. A wide range of tissue movements can be recorded while maintaining a stable relationship between the abutment analog assembly and retentive elements. The definitive cast is modified accordingly to provide an accurate reproduction of the patient's tissues during function, thus, increasing the overall retention and stability of the definitive prosthesis.
下方组织床的过度移动会导致种植体固位的硅胶耳廓假体固位不佳。本文介绍了一种两步印模技术,包括对蜡型进行二次功能性取模印模。在保持基台模拟组件与固位元件之间稳定关系的同时,可以记录广泛的组织移动情况。相应地对终印模石膏模型进行修改,以在功能状态下准确再现患者的组织情况,从而提高终修复体的整体固位力和稳定性。
