The Effect of Drying Methods with Space and Microwave Temperatures on Compression Strength and Changes in Type IV Gips Dimensions

Introduction

Type IV casts, made from pure hydrate calcium sulfate, are crucial components in the creation of artificial dentures. These casts are used to produce an accurate work model, which is essential in the process of making crowns and dental bridges. The quality of the work model is heavily influenced by its compression strength and dimensional changes. In the field of dentistry, the hardening time of the work model is a significant consideration for both dentists and engineers. To expedite this process, alternative drying methods such as microwave drying can be an effective solution. This article aims to discuss the effect of drying methods, both with space and microwave temperatures, on the compression strength and changes in the dimensions of Type IV GIPS.

Research Methods

This study employed an experimental laboratory design with a post-test only control group design. The study consisted of 60 samples of Type IV GIPS, divided into two groups: 30 samples for the compression strength test and 30 samples for the dimensional change test. The samples were tested using two drying methods:

Drying with Space Temperature at 23 °C ± 2 °C for 24 hours.
Drying with Microwave at 600 W for 5 minutes and 10 minutes.

The measurement of compression strength was conducted using a universal testing machine tool, while changes in dimensions were measured by digital calipers. The data obtained were then analyzed using the Univarian test to obtain an average value and standard deviation, as well as one-way ANOVA test to determine the effect of the drying method on the two parameters.

Research Results

The results of the analysis showed a significant difference between the two drying methods. The drying method with a microwave for 5 minutes showed p = 0.001 (p < 0.05) for compression strength and p = 0.0001 (p < 0.05) for dimensional changes. Meanwhile, the drying of the microwave for 10 minutes also showed significant results with P = 0.0001 for the two parameters tested. Further testing with the LSD test showed that drying with a 600 W microwave for 5 minutes not only increased the power of compression but also had a minimum impact on dimensional changes when compared to drying space and microwave temperatures for 10 minutes.

Additional Analysis and Explanation

Drying Type IV casts with microwave proven to be more efficient than the spatial drying method. Drying with microwave allows water molecules in the cast to evaporate faster, resulting in faster hardening without sacrificing compression power. This is very important in the practice of dentistry, where time is a key factor.

The higher compression strength shows that the resulting work model is better able to withstand the load it receives during use. Meanwhile, fewer dimensional changes mean that accuracy in printing of artificial dentures can be maintained, which is very important for patient compatibility and comfort.

Thus, the use of microwave drying methods for 5 minutes can be adopted as a faster and more effective alternative in the process of making denture work models. This not only accelerates work time, but also ensures that the quality and accuracy of the work model is maintained, providing significant benefits for dental and patient practitioners.

Conclusion

In conclusion, the study found that drying Type IV casts with microwave temperatures for 5 minutes resulted in higher compression strength and fewer dimensional changes compared to drying with space temperatures and microwave temperatures for 10 minutes. This suggests that microwave drying can be a more efficient and effective method for drying Type IV casts, resulting in better quality and accuracy of the work model. The use of microwave drying methods for 5 minutes can be adopted as a faster and more effective alternative in the process of making denture work models, providing significant benefits for dental and patient practitioners.
