  1. 1. Patient–Dentist–Technician Communication within the Dental Team: Using a Colored Treatment Plan Wax-Up LUKE S. KAHNG, CDT* ABSTRACT Communication among the restorative dental team must include the patient. The patient wants to know the details of the anticipated restorations; but because a patient is not aware of many dental innovations, care must be taken to provide them with a clear explanation of all antici- pated treatment parameters. Many patients have little understanding of today’s advancements in restorative procedures, and they may or may not understand all of the possibilities. Through effective communication, the patient gains confidence in the dental team and better understands the proposed restorative treatment. Patient satisfaction is significantly enhanced through effective communication. CLINICAL SIGNIFICANCE This article describes the use of a diagnostic wax-up to facilitate optimal communication between the dental team and the patient.
