Protrusive movement in wax is characterized by which property?

Protrusive movement in wax refers to the ability of the material to be manipulated and shaped during dental procedures, especially in the context of creating impressions or models. The characteristic of being unable to be perforated relates to the integrity and durability of the wax during manipulation. This property ensures that as the dentist or technician moves the wax in a protrusive manner—forward or outward—it maintains its structure without tearing or losing shape. This is essential for achieving accurate representations of the dental arches and ensuring that the wax can be carved or further manipulated without compromising the final result.

While other properties like adhesion, rigidity, and carving capabilities may play a role in the overall usability of the wax, the inability to be perforated is specifically relevant to protrusive movement, as it highlights the strength of the material in maintaining its form under physical stress during the procedure. Therefore, this property is crucial for effective and accurate dental work involving wax.
