Fabrication of custom overdenture attachments using indigenously made parallelometer: A technique.

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 modified technique for single-step border molding.

The sectional and the single-step are techniques for border molding. Even though the sectional technique is routinely taught in dental schools in the United States, and is followed by a large number of general dental practitioners, it is not without disadvantages. Common problems associated with the sectional technique include its time-consuming nature and the difficulty in mastering it because of the short manipulation time of the impression compound modeling plastic.
