Custom tray modification to accurately capture the lingual sulcus of an edentulous mandible
The lingual extension of a mandibular edentulous impression is the most challenging border to determine accurately. Appropriately extending the mandibular lingual flange to assist in stabilizing a removable denture can be obtained with correct understanding of anatomy and function of the floor of the mouth.1 The lingual flange rests in the alveololingual sulcus, which has an S-shaped curve that extends from the lingual frenum to the premylohyoid fossa and then curves medially from the body of the mandible to the retromylohyoid fossa.Reinforcement of an interim fixed prosthesis with a denture metal mesh
Long-term interim fixed prostheses play a critical role in the success of extensive prosthodontic rehabilitations. They allow assessment of esthetics, phonetics, masticatory function, newly established vertical dimension of occlusion, and proper occlusal scheme before fabrication of the definitive restorations. Furthermore, fixed interim restorations protect implants or tissue grafts during the osseointegration phase.1
