When should a reline of an immediate denture typically be performed by a laboratory?

  1. 1 month after placement

  2. 3 months after placement

  3. 6 months after placement

  4. 12 months after placement

The correct answer is: 6 months after placement

A reline of an immediate denture is typically performed around six months after placement to account for the natural healing and changes that occur in the oral structures following tooth extraction. Immediately after teeth are removed, the alveolar bone and soft tissues undergo significant changes as they heal and adapt to the absence of teeth. These changes can lead to alterations in the fit of the denture, which can result in discomfort or reduced function. By the six-month mark, the majority of the healing process will be completed, making it more appropriate to assess the fit of the denture and perform a reline. This timeframe allows the laboratory to create a more accurate and comfortable fit for the patient, ensuring that the denture remains functional and aesthetically pleasing. Therefore, the six-month time point is considered optimal for this procedure, balancing the need for adjustment while minimizing the likelihood of further significant anatomical changes.
