How long should a lab wait to perform a reline of immediate dentures?

The recommended wait time for performing a reline of immediate dentures is typically around 6 months. This duration is based on the understanding that immediate dentures are placed right after tooth extraction, which leads to significant changes in the shape of the edentulous ridge as it heals. During the initial healing phase, the bone and soft tissues undergo resorption and remodeling, which can alter the fit of the denture.

By waiting 6 months, clinicians allow for sufficient healing, ensuring that the reline achieved during this period will result in a better fit, comfort, and functionality for the patient. Immediate dentures often require more than one adjustment or reline to accommodate the ongoing changes within the patient's oral anatomy. Therefore, this waiting period helps guarantee that the final reline will be effective as the soft tissue and bony support normalize post-extraction.

The alternatives suggest different durations that do not align with clinical practice guidelines and the healing process following tooth extraction, resulting in a less optimal fit or comfort for the patient if performed too soon or too late.
