Patients seeking treatment for complete dentures can be categorized into two groups, those who are completely edentulous, and those with some remaining teeth. In the latter case, several treatment options are available, including immediate dentures, overdentures, and telescopic prosthesis. Another option, which is not widely practiced, is the Cu-sil denture, an alternative to overdentures, transitional dentures, conventional dentures, and full dentures. It can be used for roofless uppers and free end partials where tooth contour is insufficient to cast clasps. This technique is most commonly used in Western countries, and we have attempted a similar approach using O-ring dentures.
