A Technique to Replicate Soft Tissues Around Fixed Restoration Pontics on Working Casts

Abstract

When missing maxillary incisors are replaced, the patient's primary concern is usually esthetics. Depending on the patient's smile line and the display of the incisors, the esthetic zone may extend to the entire clinical crown and include the surrounding soft tissue. For these patients, the appearance and form of the soft tissue at the base of the pontics is as critical as the esthetics of the incisal edges of the restoration. A technique is presented to precisely transfer the soft tissue morphology of the pontic area to the working cast. This modified master cast allows the laboratory technician to fabricate restorations that will harmonize precisely with the soft tissues of the patient.

Precise Reproduction of Soft Tissue Structure around the Pontic Area Using Computer‐Aided Design and Manufacturing

“…In restorative situations using an anterior fixed dental prosthesis (FDP), an ovate pontic is often used for an esthetic result. [1][2][3][4][5][6][7] However, even when esthetic soft tissue around the pontic is obtained with an interim prosthesis, the well-formed soft tissue structure could easily deform during a final impression procedure because of the absence of a supporting structure from the interim prosthesis and the pressure of the silicone impression material. 2,8 The well-formed soft tissue structure begins to deform quickly after an interim prosthesis is removed to make a final impression.…”
