A standard stainless steel specimen of 76 x 76 x 9.5 mm was made. Vertical and horizontal grooves were made on the specimen as reference marks. The horizontal grooves were in different depths and widths. The duplicating materials were prepared and poured over the standard die to make a negative likeness. These negatives were poured with the same investment material. Twelve investment specimens were measured for accuracy and detail reproduction with a Talysurf finish analyzer. Results of this study indicated that polyvinyl siloxane and polyelher rubbers are superior in accuracy compared to the agar reversible hydrocolloid. No significant differences in detail reproduction were noted in anv of the duplicating materials tested.  ISSN : 0  Journal Name : Saudi Medical Journal  Volume : 7  Issue Number : 1  Publishing Year : 1995 AH 1995 AD  Article Type : Article  Added Date : Saturday, June 21, 2008  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email سلمى باحنان Bahnnan, Salma Investigator Doctorate Sbahnnan@kau.edu.sa أحمد عبد الحميد Abd El-Hamid, Ahmed Researcher Doctorate   محمد عبد الحليم Abd E-Halim, mohammad Researcher Doctorate   Files File Name Type Description  ACCURACY AND REPRODUCIBIUTY OF REVERSIBLE.pdf pdf   Back To Researches Page
