The correct option regarding the use of an extruder gun in dental applications is that it dispenses calibrated mixing of rubber bases. An extruder gun is specifically designed to handle materials that need to be mixed and applied in precise proportions, which is particularly important when working with rubber bases used for creating impressions. The device ensures that the materials are uniformly mixed and delivered in a controlled manner, allowing for optimal consistency and accuracy in the dental procedure. This accurate dispensing helps in achieving the right material properties necessary for creating high-quality dental impressions.

Other options involve functions that are not typically associated with an extruder gun in dental settings. Spraying dental materials, applying heat, or curing dental resins may utilize different tools and equipment specifically designed for those tasks. Thus, the role of the extruder gun remains focused on the precise dispensing and mixing of rubber bases essential for impressions.
