Background : surface area anatomy is a proportional point to the retention of complete denture, in past there was no quantitative method to evaluate the surface area, nowadays the size and shape of maxillary arch is measured by different electronically and mathematical devices. A study was therefore, undertaken to measure surface area of upper dental cast that was taken by different final impressions. Materials and methods: twenty patients were examined. All of them had a healthy palate with no singe of injury, trauma, or deformity. Casts were taken by three different final impressions; zinc oxide, additional silicon, and poly ether. And two different devices were used; the computerized one and the Aluminum foil measure. Age, sex, and shape of upper dental arch were also evaluated. Results: the results of this study showed that the use of different methods to measure the surface area of upper dental cast had a significant difference between the two different measurements, while there was no difference in the measurements between the different final materials. Age variable showed more significant difference between the first and second method than sex variable. Conclusion: data collected in the present investigation showed a highly significant difference in measurements between the computerized method and the direct foil method. Zinc oxide, silicon and poly ether materials showed no significant differences in readings.
Departments and offices of public relations and media in any institution or company is the most important departments that reflect the results of their work negatively or positively on their reputation.

The analysis of Least Squares: LS is often unsuccessful in the case of outliers in the studied phenomena. OLS will lose their properties and then lose the property of Beast Linear Unbiased Estimator (BLUE), because of the Outliers have a bad effect on the phenomenon. To address this problem, new statistical methods have been developed so that they are not easily affected by outliers. These methods are characterized by robustness or (resistance). The Least Trimmed Squares: LTS method was therefore a good alternative to achieving more feasible results and optimization. However, it is possible to assume weights that take into consideration the location of the outliers in the data and det
