Various types of attachments have been used during overdenture fabrication; however, no single attachment is perfect for every case. Irrespective of the attachment used, it is important to maintain parallelism between the attachments for ease of insertion and removal, functional efficiency, and durability of the prosthesis. It is challenging to obtain parallelism between attachments when the abutments are divergent, or multiple abutments are engaged. A simplified technique to fabricate cast overdenture attachments using indigenously made parallelometer has been described. This technique eliminates the need of making full-arch impressions and models and surveying the attachments before casting. With this technique, there is a reduction in the duration and cost of treatment, without any compromise in quality of the prosthesis.
在覆盖义齿制作过程中使用了各种类型的附着体;然而,没有一种附着体适用于所有情况。无论使用何种附着体,保持附着体之间的平行度对于便于义齿的插入和取出、功能效率以及假体的耐用性都很重要。当基牙分散或涉及多个基牙时,要使附着体之间获得平行度具有挑战性。本文描述了一种使用国产平行仪制作铸造覆盖义齿附着体的简化技术。该技术无需制作全口印模和模型,也无需在铸造前对附着体进行测绘。采用这种技术,治疗时间和成本得以降低,而假体质量不受任何影响。
