Abstract
Introduction: Precision in terms of the marginal seal and the occlusal seat of an indirect dental restoration is the result of the precisely made impression. Many factors that should receive proper attention to make precise impression are technique; tray type, impression type, thickness of wash bulk, impression bulk, polymerization and thermal shrinkage etc affect the accuracy and stability of the impression.
Introduction: Precision in terms of the marginal seal and the occlusal seat of an indirect dental restoration is the result of the precisely made impression. Many factors that should receive proper attention to make precise impression are technique; tray type, impression type, thickness of wash bulk, impression bulk, polymerization and thermal shrinkage etc affect the accuracy and stability of the impression.
Aims and objectives: This study was conducted to evaluate the effect of the bulk on the accuracy of an elastomeric impression material. Materials and methods: The impression of the stainless steel dies with 8mm base diameter and 8mm height with 60 taper was made in the perforated stainless steel cylindrical trays with inside diameter of 12mm, 14mm and 16mm to produce respective material thickness of 2mm, 3mm and 4mm in polysulfide, addition silicone and polyether impression materials. The impression was the poured in Type IV dental stone high strength (Ultrarock, Kalabhai, Karson Pvt. Ltd., India). The die dimensions were measured with the travelling microscope and compared with master die.
Results: The data upon statistical analysis revealed that impression bulk thickness affects the stone dies significantly.
Conclusion: Within the limitations of the study, it can be concluded that the impression bulk significantly affects the die dimensions
