The retromylohyoid area is an important anatomical region in the lower denture that contributes to the retention and stability of the denture. The lateral throat form, which is the space between the retromylohyoid flange and the surrounding tissues, should be adequately large (approximately one-half inch) to allow for proper function and comfort of the denture. A well-formed lateral throat area helps in achieving a good seal and prevents food impaction.
