Integration of an intraoral scan and a conventional impression for fabricating complete dentures for a patient with flabby tissues


      Inflammatory movable tissues in the maxillary anterior region are the result of excessive stimulation of the anterior alveolar ridge, as the maxillary denture habitually rotates anteriorly and upward during mastication. The pressure required for a functional impression makes it difficult to obtain the accurate anatomy of the inflamed mucosal tissues. An intraoral scanner can be used to record the movable tissues in an immobile state. However, for removable dentures, the oral scanner is limited by the difficulty in evaluating the denture borders or the posterior palatal seal area accurately. The fabrication of a complete denture by combining the use of an oral scanner to capture an anatomic impression without exerting pressure on the maxilla, including the movable tissues, and a traditional functional impression using the closed-mouth technique is described.
