Replacement of missing ears is a challenging task in which extensive array of materials and techniques have been employed. This article describes a different and simplified procedure for fabricating auricular prostheses very similar to the intact left ear of the patient. A 65-year-old male patient was referred to the Department of Prosthodontics with the loss of the right ear. In this case, the impression was made using hydrocolloid material (alginate) from the both defected and the opposite side. After hardening of the stone casts, a custom-made transparent splint plate was designed for the left auricular side. The splint was reversed and a cast model of the right auricular side was obtained as pouring the dental stone into transparent orthodontic splint. After getting the impression from cast model, conventional wax pattern and try on process was done. Finally, silicone elastomer was polymerized and the retention of the prosthesis acquired with the magnetic attachments. The technique described is economical, conventional, and time-saving. Furthermore, the prosthesis imitates the patient's intact auricular tissue.
替换缺失的耳朵是一项具有挑战性的任务，人们已经采用了各种各样的材料和技术。本文描述了一种不同的、简化的制作耳假体的方法，该假体与患者完好的左耳非常相似。一名65岁男性患者因右耳缺失被转诊至口腔修复科。在这个病例中，使用水胶体材料（藻酸盐）从缺损侧和对侧制取印模。石膏模型硬化后，为左耳侧设计定制的透明夹板。将夹板翻转，把牙科石膏倒入透明正畸夹板中，获得右耳侧的铸型模型。从铸型模型制取印模后，进行传统的蜡型制作和试戴过程。最后，使硅橡胶弹性体聚合，并通过磁性附着获得假体的固位。所描述的技术经济、常规且省时。此外，该假体模仿了患者完好的耳部组织。
