Futhermore, while continuous attempts are being made to enhance these materials, the ideal impression material has yet to be developed. To accomplish these goals, impression materials were essential. 21. The results show that a reheating of the impressions to mouth temperature before die casting reduces their inaccuracy significantly. Because the porcelain would not degrade in the wearer’s mouth like dentures made from human or animal teeth,1this innovation led to exploring different applications for ceramics as a restorative material. Heterogeneity amongst the studies in direct comparison was assessed using Chi-square and I2 tests using the Inverse variance heterogeneity model. The combination material is less accurate when many abutment preparations are to be reproduced. Overall time taken for digital interventions in decreasing order were: LAVA Cos (8.14[3.64, 12.26] (statistically significant);I TERO (4.11 [-1.02, 9.24]); CEREC(0.34[-4.14, 4.82]) CONCLUSION: There was an overall preference for digital impressions, although the time required is longer.
