精细印模两步法应用于下颌低平牙槽嵴单颌总义齿修复的临床体会

Clinical application of two-step fine impression into single complete denture with mandibular alveolar ridge atrophy

目的探讨精细印模两步法在下颌低平牙槽嵴单颌总义齿修复中的临床效果。方法选取1例下颌牙全部缺失、牙槽嵴低平的患者,采用后端开窗式的托盘经过个性化调改后获取初印模,结合下颌吸附性义齿的理念制作个别托盘,用不同稠度的硅橡胶主动性边缘整塑后获取终印模。结果通过精细印模两步法的取模,对该例患者制作的单颌总义齿固位及功能良好,舒适度高。结论精细印模两步法应用于下颌低平单颌总义齿的修复效果良好。

Objective The present study investigated the clinical effects of a single complete denture using two-step fine impression during the restoration of mandibular alveolar ridge atrophy. Methods A back-end window traythat was personalized and adjusted was used to obtain the original impression for a mandibular alveolar ridge case. Theindividual trays were made with the conception of mandibular occlusal denture, and the final impression was obtainedafter active edge shaping using different viscous silicones. Results A case of single complete denture with mandibularalveolar ridge atrophy restoration was accomplished using a single complete denture and two-step fine impression. Thedenture was well fixed and functioned well, and the patient was satisfied. Conclusion The application of fine impres-sion into a single complete denture is helpful for the restoration of mandibular alveolar ridge atrophy.
