Soft Liner–Retained, Implant-Supported Overdenture: A Technical Note

Joseph R. Cain, DDS, MS, Donald L. Mitchell, DDS, MS.

PMID: 9857598

This paper describes the design and fabrication of a soft liner–retained, implant-supported overdenture used in 10 patients over a period of 1 to 6 years. A final complete denture impression is made of the dental arch, including implant abutments extending 5 mm above the gingival tissue. The master cast is fabricated with actual abutments placed in the impression. After the final wax try-in, the denture is flasked in the usual manner with the metal abutments in place. Before packing with acrylic resin, plastic tubing 1 to 2 mm thick is placed around each abutment. The denture is trial packed and allowed to bench cure over night. The plastic tubing is then removed and a soft denture lining material is placed in these areas only. The flask is closed and cured according to the manufacturers recommendation. The denture is delivered as a conventional overdenture. (INT J ORAL MAXILLOFAC IMPLANTS 1998;13:857–860) Key words: dental implant, overdenture, soft liner, treatment planning
