Vaginal agenesis is one of the major congenital anomalies affecting women. Postoperative prosthetic vaginal dilators are indicated in patients treated surgically for vaginal agenesis. Although different dental materials such as acrylics and silicone-coated materials are used, addition silicones alone have never been used for the fabrication of prosthetic vaginal dilators. Addition silicone materials have advantages, such as high elastic recovery, high tear and tensile strengths, which aid in the definitive use of vaginal dilators. Vaginal dilators fabricated using addition silicone materials act as an efficient prosthesis in terms of function and ease of use in surgically treated vaginal agenesis patients.
阴道闭锁是影响女性的主要先天性异常之一。对于接受手术治疗阴道闭锁的患者，术后需使用人工阴道扩张器。虽然使用了不同的牙科材料，如丙烯酸树脂和硅胶涂层材料，但仅加成型硅酮从未用于制造人工阴道扩张器。加成型硅酮材料具有诸如高弹性回复率、高撕裂强度和拉伸强度等优点，这有助于人工阴道扩张器的最终使用。就功能和在接受手术治疗的阴道闭锁患者中的易用性而言，使用加成型硅酮材料制造的阴道扩张器是一种有效的假体。
