AIM
To evaluate the best method of overlay generation out of the three methods, i.e., manual, photocopying, and computer assisted method.
MATERIALS AND METHODS
Impressions of maxillary and mandibular arches of 25 individuals participating in the study were made and dental study models were prepared. Overlay production was done by manual, photocopying, and computer assisted methods. Finally, the overlays obtained by each method were compared.
RESULTS
Kruskal Wallis ANOVA H test was used for the comparison of manual, photocopying, and computer assisted overlay generation methods. H value being highest in case of computer assisted overlays, thus, making it the best method of overlay generation out of the three methods.
CONCLUSION
We conclude that the method of computer assisted overlay generation is the best among the three methods used in our study.
目的
评估三种方法（即手工法、复印法和计算机辅助法）中生成覆盖物的最佳方法。
材料与方法
对参与研究的25名个体的上颌和下颌牙弓进行印模，并制作牙科研究模型。通过手工法、复印法和计算机辅助法制作覆盖物。最后，对每种方法获得的覆盖物进行比较。
结果
采用Kruskal Wallis方差分析H检验对手工法、复印法和计算机辅助覆盖物生成方法进行比较。计算机辅助覆盖物的H值最高，因此使其成为三种方法中生成覆盖物的最佳方法。
结论
我们得出结论，在我们研究中使用的三种方法中，计算机辅助覆盖物生成方法是最佳的。
