Assembly and clinical use of the XCP-ORA: a three-function dental X-ray film positioning device for taking anterior and posterior periapical and bitewing intraoral radiographs.

This article describes the assembly and clinical use of a newer type ofXCP dental X-ray film positioning device, called the XCP-ORA. The previous version of the XCP consists of three separate devices for taking anterior, posterior, and bitewing radiographs. The XCP-ORA dental X-ray film holder combines all three of these dental X-ray functions into one device, in contrast to theprevious generation ofXCP holders. The large paralleling ring of the device contains three color-coded square-shaped holes that attach to a metal rod. This single metal rod with two right angle bends contains two sets of corresponding color-coded prongs that attach the anterior, posterior and bitewing X-ray film holders. One set of prongs consists of two red prongs that correspond to the insertion points of the bitewing X-ray film holder. The other set of prongs consists of one prong that is yellow colored, and another prong that is blue colored. Both of these prongs fit into the insertion holes of either the yellow (posterior) or the blue (anterior) film holders. The multi-function XCP-ORA device reduces the total number of XCP parts that are needed to take intraoral dental radiographs. Fewer parts make the device less confusing to assemble and reduce the number of steps that are needed to prepare the XCP-ORA parts for autoclaving.
