When harmonizing occlusion during RPD placement, what must be ensured?

• A. RPD must keep natural teeth apart
• B. RPD does not alter contacts with natural teeth
• C. RPD changes the contact pattern of natural teeth
• D. Framework should guide mandible movement

Answer: (B)

Ensuring that the removable partial denture (RPD) does not alter contacts with natural teeth is crucial for maintaining proper occlusion. This means that when the RPD is in place, the interactions between the natural teeth remain unchanged, preventing any unnecessary stresses or disruptions to the bite. When an RPD is designed and fitted correctly, it integrates smoothly into the existing occlusion, allowing for proper forces to be distributed across the dental arch during function. This stability helps in preserving the health of the remaining natural teeth as well as the supporting structures, such as the gums and bone. Maintaining the existing contacts is also important for the patient's comfort and functionality, as it helps in maintaining the usual chewing patterns and minimizes adjustment periods. Additionally, if the RPD were to change the existing contact pattern significantly, it could lead to discomfort, misalignment, or even detrimental changes in the occlusion over time. Thus, the focus on not altering existing contacts is fundamental to achieving harmony in occlusion with the placement of an RPD.
