Where is the larger circumference of the cord placed during a packing procedure?

The larger circumference of the cord is placed at the occlusal surface during a packing procedure to ensure that the cord effectively displaces the gingival tissue and adequately creates a space for impression material in restorative dentistry. This placement helps in achieving a better marginal detail and a more accurate impression, which is crucial for the success of the restoration. By positioning the cord at the occlusal surface, the dental assistant or dentist can manipulate and control the tissue more effectively and obtain a clearer impression of the prepared tooth and surrounding structures. Ensuring this positioning allows for a precise fit of the final restoration and contributes to the overall success of the dental procedure.
