Evaluation of retentivity of different clasp materials in interim maxillary distal extension prosthesis,
, Giza, Cairo University, 2010.
AbstractThe use of metal clasps on anterior teeth may cause esthetic problems; recently acetal resin and Versacryl have been used as alternative materials to improve esthetics, Material and Methods: Ten patients were selected to receive an interim partial denture with different clasp materials, retention of different clasp materials was measured by using digital force meter. Results: There was a significant difference in the retention between the three different materials, the Versacryl clasp showed more retention than the wrought wire clasp followed by the acetal resin clasp. Conclusion: within the limitation of this study it was shown that the retention of the Versacryl clasp was the highest and the retention of acetal resin clasp was closer to the wrought wire clasp.
