Final answer:
The statement is true; tissue conditioner and soft reline can indeed be used on a complete denture at any time to adjust fit and aid in tissue healing.
Step-by-step explanation:
The statement that you can use tissue conditioner and soft reline on a complete denture (CD) at any time is true. Tissue conditioners and soft relines are materials used to adjust the fit of a denture, particularly when the oral tissues have changed or when there is a need to help the tissues heal after extractions or other dental procedures. They can be applied by a dentist or a dental technician whenever it is necessary to improve the comfort and fit of the denture for the patient.
Tissue conditioners are typically temporary soft materials placed inside a denture to reduce irritation and help tissues recover. Soft relines are similar but can last for a longer period. They are useful when the gums have resorbed or when inflammation has caused changes in the oral mucosa, thereby changing the fit of the denture.
