C – control (master model); PP – pre preparation putty; GP – gouging putty (post preparation putty); PS – polythene spacer; CT – conventional temporary; MT – modified temporary; ANOVA – analysis of variance; SD – standard deviation. Point angles: P1 (mesiobuccal distobuccal occlusal), P2 (mesiopalatal distopalatal occlusal), P3 (mesiobuccal occlusal), P4 (mesiopalatal occlusal), P5 (distobuccal occlusal), P6 (distopalatal occlusal); line angles: L1, L4 (mesiobuccal), L2 (mesiopalatal), L3, L5 (distobuccal), L6 (distopalatal); curved surface: C1, C3 (center of buccal), C2, C4 (center of palatal); flat surface: F1, F3 (center of mesial), F2, F4 (center of distal). Statistical interpretation: Test used: least significant difference (LSD) post hoc Tukey test; level of the degree of significance was determined on the value of ^* – significant.
