Which device is used to shape the contour of the lips?

The device used to shape the contour of the lips is the Mouth Former. This specialized tool is designed specifically for contouring and molding the lips after death, ensuring that they are aesthetically pleasing and properly positioned for viewing during memorial services. The Mouth Former helps maintain the desired lip shape, which is critical in restorative art and embalming practices, creating a natural and lifelike appearance.

Other options do not fulfill this specific purpose. The Needle Injector is primarily used for injecting embalming fluid or other substances into the tissues, which is more about preservation than shaping. Musculature Sutures relate to stitching techniques to secure tissue and maintain anatomical positions but are not specifically used for shaping the lips themselves. On the other hand, a Pathological Discoloration Agent is used to address color irregularities in tissues but does not serve to contour or shape the lips. Thus, the Mouth Former stands out as the correct choice for this particular function.
