What is the purpose of the modified pen grasp in coronal polishing?

The purpose of the modified pen grasp in coronal polishing primarily revolves around enhancing control and balance of the handpiece. This technique involves holding the handpiece similarly to how one would hold a pen, which facilitates better maneuverability and precision during the polishing procedure. With a secure yet relaxed grip, the dental hygienist can apply appropriate amounts of pressure and maintain stability, even in tight spaces within the oral cavity.

This grip is particularly beneficial because it promotes a less fatigued hand, allowing for longer periods of effective polishing without compromising the quality or accuracy of the work. Enhanced control also means that the hygienist can navigate around curves and contours of the teeth more easily, leading to a thorough and effective polishing process.

In contrast to other methods that may focus only on visibility or access to specific areas, the modified pen grasp prioritizes the operator's comfort and effectiveness during the procedure, making it a fundamental technique in coronal polishing.
