Soft liner-retained, implant-supported overdenture: A technical note

This paper describes the design and fabrication of a soft liner-retained, i mplant-supported overdenture used in 10 patients over a period of 1 to 6 ye ars. A final complete denture impression is made of the dental arch, includ ing implant abutments extending 5 mm above the gingival tissue. The master cast is fabricated with actual abutments placed in the impression. After th e final wax try-in, the denture is flasked in the usual manner with the met al 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 a nd 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 manufacturer's recommendation. The dentu re is delivered as a conventional overdenture. (Int J Oral Maxillofac Impla nts 1998;13:857-860).
