Storage Time Effect of Wax Patter to Distortion of Castings Metal Framework
Technicians fail in getting accuracy and dexterity of the cast mental feamework denture in Dental Technic Laboratories. Metal framework was distorted from an early from of wax pattern at night so it is not fixed in position. This is likely due to the nature of wax is so complex compared with other dental materials. This is likely due to the nature of wax is complex compared with other dental materials. This experimental-research laboratory with a complete-randomized-block-design is to determine the effect of stoage time on the wax pattern disortion of the metal frame castings. Research subjects in from of acrylic plates under the application of castings on the refreactory model and measured its thicjness with a digital califer castings at a certain point (TI,T2,T3 and grip end) with the help of self-curing acrylic. The sample is a model refractory RA (42 models) and has been waxing with wax pattern design major type connectors Single Bars and palatal strap, and stronge 1,3 and 7 days. Data were tested statistically by SPSS windows 13 (p
